Heart cell transplant rejections
The concept that cell transplantation is the answer to the treatment of heart failure may have suffered a major setback as a result of a research scam perpetrated at Harvard University’s Brigham and Women’s Hospital in Boston.
The fraudulent cardiac research at that institution was from the lab of Piero Anversa, MD, which falsified or fabricated data. Dr. Anversa was one of the leaders in pursuing the concept that adult cardiomyocytes can not only regenerate by cell division but can also be transplanted from one animal to another, in his case a mouse.
The original reports over a decade ago caused a major stir in heart failure research. They also were met with considerable skepticism in the research field and have not been reproduced in other laboratories. Numerous small trials in humans have been unsuccessful in demonstrating the survival of autologous cells transplanted in both animal and humans. Dr. Anversa’s research has been under scrutiny by Harvard and Brigham and Women’s since 2013, ultimately resulting in the call to retract 31 published studies in mid-October. In the meantime, admission of fraud in regard to the original Anversa papers resulted in a fine of $10 million paid by the institutions to the National Institutes of Health in a 2017 settlement. Dr. Anversa left Harvard in 2015.
Nevertheless Dr. Anversa’s concepts led to the initiation of an NIH-supported multicenter trial in humans of the implantation of autologous bone marrow cells using endocardial devices to transplant cells in 144 patients with heart failure. The Combination of Autologous Bone Marrow Derived Mesenchymal and C-Kit+ Cardiac Stem Cells as Regenerative Therapy for Heart Failure (CONCERT-HF) was started in 2015 and was still recruiting until Oct. 29, when the National Heart, Lung, and Blood Institute announced that a pause in recruitment was called in order to review the fraudulent data that led to the trial’s initiation. Patients were to be followed over a 1-year period using delayed-enhanced magnetic resonance imaging (DEMRI) scans to assess scar size and left ventricular function and structure at baseline and at 6 and 12 months post study product ad-ministration. For the purpose of the endpoint analysis and safety evaluations, the investigators planned to use an intention-to-treat study population evaluating a number of clinical parameters.
Anatomists and physiologists have long been of the opinion that adult human and mammalian cardiomyocytes are terminally differentiated and do not undergo cell division. However, over time, cardiomyocytes can undergo hypertrophy as a result of increased workload. Cells can die as a result of ischemia, infarction, or stress mediated through unchecked inflammatory processes. It also has been shown that cells can die as a result of apoptosis, particularly in areas in proximity to myocardial scars. It is generally believed that these three methods of cell depletion contribute to the progression of heart failure. Dr. Anversa also proposed that there is some degree of replication of cardiomyocytes but not to a degree that can have a meaningful replacement value.
The concept of cell transplantation in medicine certainly has been in the forefront of clinical research in medicine for the last decade based in part on research by Dr. Anversa and others in cardiology and numerous investigators in other medical disciplines. With few exceptions, there has been little support for the clinical benefit of these clinical studies. We are unfortunately now faced with the release of the tainted fraudulent research that led to CONCERT-HF. Whether there is anything of scientific value to come of the trial is highly unlikely.

Antimalarial-induced cardiomyopathy in lupus may be underrecognized
Cardiomyopathy induced by antimalarial treatment for systematic lupus erythematosus may not be as rare as previously thought, according to the authors of a case series published Oct. 15 in The Journal of Rheumatology.
The paper describes eight patients attending a lupus clinic, who were diagnosed with definite or possible antimalarial-induced cardiomyopathy over the course of 2 years.
Konstantinos Tselios, MD, PhD, a clinical research fellow at the University of Toronto Lupus Clinic, and his coauthors wrote that antimalarial-induced cardiomyopathy was thought to be relatively rare, with only 47 previous isolated reports, but they suggested the complication may be significantly underrecognized.
“Hypertrophic cardiomyopathy and heart failure, the most common clinical features of AM-induced cardiomyopathy (AMIC), may be falsely attributed to other causes, such as arterial hypertension or ischemic cardiomyopathy,” the authors wrote. “Consequently, nonspecific therapeutic approaches with diuretics and/or antihypertensives will exert minimum or even deleterious effects on such patients.”
All eight patients in this series were female, with a median age of 62.5 years, median disease duration of 35 years, and median antimalarial use of 22 years. They presented with conditions such as heart failure, exertional dyspnea, and pedal edema. Several patients were asymptomatic but had been found to have elevated heart biomarker levels that prompted further investigation.
All patients showed abnormal cardiac troponin I and brain natriuretic peptide levels, and seven of the eight also had chronically elevated creatine phosphokinase.
In three patients, endomyocardial biopsy showed cardiomyocyte vacuolation, intracytoplasmic myelinoid inclusions, and curvilinear bodies.
Four patients were diagnosed based on cardiac MRI, which showed features suggestive of antimalarial-induced cardiomyopathy, including ventricular hypertrophy with or without atrial enlargement and late gadolinium enhancement in a nonvascular pattern.
All patients had left ventricular hypertrophy, and four also had right ventricular hypertrophy. Only one patient showed impaired systolic function, compared with around half of patients in the literature with antimalarial-induced cardiomyopathy, but seven patients showed a restrictive filling pattern of the left ventricle.
“It seems possible that AMIC is a chronic process and systolic dysfunction will become apparent only in late stages,” the authors suggested.
One patient showed complete atrioventricular block, left ventricular and septal hypertrophy, and concomitant ocular toxicity.
After patients stopped antimalarials, the hypertrophy regressed and heart biomarkers decreased in seven patients, but one patient died from refractory heart failure.
Based on their findings, the authors proposed that heart-specific biomarkers be used as a regular screening tool for detecting myocardial injury, followed by more thorough investigations, such as cardiac MRI, in patients with positive biomarker findings.
“However, drug cessation should be prompt and probably upon suspicion of AMIC, because complete investigation may be delayed significantly.”

HF unlikely in pregnant cancer survivors without history of cardiotoxicity
The risk of adverse cardiac events in female cancer survivors during pregnancy is low unless there is a history of cardiotoxicity, according to Shiying Liu, MD, of the University of Toronto, and her associates.
In a research letter published in the Journal of the American College of Cardiology, Dr. Liu and her associates reported on a retrospective chart review of 78 women with 94 pregnancies who had previously received cancer therapy who were seen at Mount Sinai Hospital between 2005 and 2015. Of these, 15 pregnancies occurred in 13 women with a prior history of cardiotoxicity. The primary outcome was a composite of cardiac events including cardiac death, heart failure (HF), acute coronary syndrome, and sustained arrhythmia.
HF occurred during five pregnancies in four women; no other adverse cardiac events occurred during the study period. All four of the women who experienced HF had a history of cardiotoxicity. There was no difference in age at cancer diagnosis, age at pregnancy, cancer type, or exposure to anthracyclines between those who did and did not experience HF, but women who developed HF were more likely to have left ventricular systolic dysfunction at the first antenatal visit (75% vs. 8%; P = .004) and to be on cardiac medications (50% vs. 8%; P = .026).
“The risk of developing [HF] during pregnancy is rare in female cancer survivors without a history of cardiotoxicity. These women can be reassured that they are at a very low risk of developing [HF] during pregnancy. Women who have a history of cardiotoxicity have an approximately one in three chance of developing [HF] during pregnancy and should receive close cardiac surveillance during pregnancy at a center with expertise in cardiac disease in pregnancy,” the authors concluded.

ADVENT-HF early results: High ASV compliance, no safety concerns
SAN ANTONIO – The in heart failure patients with sleep apnea, so far has better compliance than previous trials, with no safety concerns to date, according to investigator T. Douglas Bradley, MD.
On average, patients with obstructive sleep apnea were using the device 4.6 hours per night at 1 month and 4.1 hours at 12 months, while patients with central sleep apnea were using the device 5.2 hours per night both at 1 month and 12 months, Dr. Bradley said.
“This represents much better compliance than the other trials that have looked into this area, so we are quite happy about that,” Dr. Bradley said at the annual meeting of the American College of Chest Physicians.
The study has been reviewed five times by the data safety monitoring board since the announcement of SERVE-HF trial results, with no safety concerns in either obstructive sleep apnea or central sleep apnea patients, Dr. Bradley noted in a podium presentation.
The compliance results have been submitted for publication, though efficacy results of the study will have to wait. The estimated study completion date is June 2020, according to the latest study information on ClinicalTrials.gov.
More than 600 patients have been enrolled in ADVENT-HF to date, and the investigators hope to enroll more than 800: “We should be there by the end of next year,” Dr. Bradley said.
He provided disclosures related to Philips Respironics (funding and devices) and the Canadian Institutes of Health Research.

Short-term NSAIDs appear safe for high-risk patients
in a retrospective, observational study.
The findings of the study challenge the Choosing Wisely campaign of the American Society of Nephrology, which recommends against NSAIDs for high-risk patients, according to lead author Zachary Bouck, MPH, of the department of medicine at Sunnybrook Health Sciences Centre in Toronto, and his coauthors.
“While these recommendations offer basic analgesics and nonpharmacological treatments as preferable alternatives, it is both possible and disconcerting that some physicians might instead prescribe opioids, which typically pose elevated risk of adverse events and dependence vs. NSAIDs,” the investigators wrote. The report is in JAMA Internal Medicine.
They sought to estimate the frequency and characteristics of NSAID prescriptions while also looking for associations with acute renal and cardiovascular complications. The retrospective, observational study involved 814,049 adults with musculoskeletal disease and 7,365 primary care physicians in Ontario, Canada. All patients were aged 65 years and older, and had been diagnosed with hypertension, chronic kidney disease, or heart failure in the past year. Instances in which a patient was prescribed an NSAID within 7 days of presentation were included.
To assess for associations between prescription NSAIDs and negative outcomes, the investigators searched for renal or cardiovascular complications within 37 days of presentation. Over-the-counter NSAID usage was not evaluated.
There were 224,825 visits. An NSAID was prescribed after 9.3% of these visits.
Renal and cardiovascular outcomes were similar between high-risk patients who received a prescription NSAID and those who did not (absolute risk reduction, .0003; P = .74).
“The similarity in risk between users and nonusers, each group primarily consisting of patients with hypertension, suggests that the short-term association of NSAIDs in high-risk patients with musculoskeletal pain may not be as dangerous as initially thought,” the authors concluded.
The investigators found that prescribing rates varied widely, ranging from 6.7% to 14.4% of different health regions, and from 0.9% to 60.3% among 688 primary care practices, with “substantial variation in use” among primary care physicians.
The authors acknowledged limitations, including the use of administrative data, but noted that their study, showing substantial variations in NSAID prescribing, “along with the identification of patient and physician characteristics associated with NSAID use, presents an opportunity for quality improvement, with some potential targets for any resulting interventions,” they wrote.
The Institute for Clinical Evaluative Sciences funded the study. The authors reported compensation from the Canadian Institute of Health Research, the department of family and community medicine at the University of Toronto, the Heart and Stroke Foundation of Canada, and Women’s College Hospital.

The study by Bouck and colleagues found that short-term prescription NSAIDs were safe for high-risk patients; however, physicians should consider the inherent limitations of observational studies before altering clinical decisions, according to Jonathan Zipursky, MD, and David N. Juurlink, MD, PhD. This is particularly important since the findings challenge the American Society of Nephrology, which recommends against NSAIDs in patients with chronic kidney disease (CKD), heart failure, or hypertension.
Among the advantages of observational studies over randomized trials is that they often include patients not eligible for randomized controlled trials, “and extended follow-up enables examination of outcomes that might not have arisen earlier in treatment,” they wrote in an editorial. “Moreover, sample sizes often greatly exceed those of RCTs, facilitating detection of less common adverse events.

This is particularly important since the findings challenge the American Society of Nephrology, which recommends against NSAIDs in patients with chronic kidney disease (CKD), heart failure, or hypertension.

in a retrospective, observational study.
The findings of the study challenge the Choosing Wisely campaign of the American Society of Nephrology, which recommends against NSAIDs for high-risk patients, according to lead author Zachary Bouck, MPH, of the department of medicine at Sunnybrook Health Sciences Centre in Toronto, and his coauthors.
“While these recommendations offer basic analgesics and nonpharmacological treatments as preferable alternatives, it is both possible and disconcerting that some physicians might instead prescribe opioids, which typically pose elevated risk of adverse events and dependence vs. NSAIDs,” the investigators wrote. The report is in JAMA Internal Medicine.
They sought to estimate the frequency and characteristics of NSAID prescriptions while also looking for associations with acute renal and cardiovascular complications. The retrospective, observational study involved 814,049 adults with musculoskeletal disease and 7,365 primary care physicians in Ontario, Canada. All patients were aged 65 years and older, and had been diagnosed with hypertension, chronic kidney disease, or heart failure in the past year. Instances in which a patient was prescribed an NSAID within 7 days of presentation were included.
To assess for associations between prescription NSAIDs and negative outcomes, the investigators searched for renal or cardiovascular complications within 37 days of presentation. Over-the-counter NSAID usage was not evaluated.
There were 224,825 visits. An NSAID was prescribed after 9.3% of these visits.
Renal and cardiovascular outcomes were similar between high-risk patients who received a prescription NSAID and those who did not (absolute risk reduction, .0003; P = .74).
“The similarity in risk between users and nonusers, each group primarily consisting of patients with hypertension, suggests that the short-term association of NSAIDs in high-risk patients with musculoskeletal pain may not be as dangerous as initially thought,” the authors concluded.
The investigators found that prescribing rates varied widely, ranging from 6.7% to 14.4% of different health regions, and from 0.9% to 60.3% among 688 primary care practices, with “substantial variation in use” among primary care physicians.
The authors acknowledged limitations, including the use of administrative data, but noted that their study, showing substantial variations in NSAID prescribing, “along with the identification of patient and physician characteristics associated with NSAID use, presents an opportunity for quality improvement, with some potential targets for any resulting interventions,” they wrote.
The Institute for Clinical Evaluative Sciences funded the study. The authors reported compensation from the Canadian Institute of Health Research, the department of family and community medicine at the University of Toronto, the Heart and Stroke Foundation of Canada, and Women’s College Hospital.

Home telemonitoring for heart failure cuts mortality
MUNICH – A comprehensive home telemonitoring program paid off big for selected patients with heart failure in a large, German nationwide masked randomization trial.
First, TIM-HF2 didn’t rely on passive monitoring of the patients’ daily electronically submitted home data. Instead, the data went straight to a central telemonitoring center staffed 24/7 by physicians and nurses with heart failure expertise. There, the information was immediately analyzed using proprietary telemedical analytic software known as the Fontane system. The software employs individually tailored, self-adapting algorithms in order to alert staff when trouble is brewing.
But the telemonitoring intervention doesn’t merely detect early clinical deterioration. It’s also a vehicle for ongoing patient education, outpatient adjustment of drugs, management of major comorbid conditions, and hospital admissions as needed. The patient’s local primary care physician was also plugged into the remote monitoring system and kept abreast of the patient’s condition.
Second, TIM-HF2 focused on a carefully selected subgroup of heart failure patients whom prior studies suggested were particularly likely to benefit from home telemedical management. All participants were NYHA class II or III with a left ventricular ejection fraction of 45% or less, a hospitalization for heart failure within 12 months prior to randomization, and free of moderate or severe depression as evidenced by a baseline Patient Health Questionnaire-9 score of 9 or less, explained Dr. Koehler, head of the center for cardiovascular telemedicine at Charite University in Berlin.
Why exclude patients with depression?
“In this concept, with wholistic remote patient management, we need an active patient who is able to measure every day, who is able to communicate with the telemedical center, and who is able to communicate in this network created between the telemedical center and local caregivers. If someone is really depressed, unable to act, lying in bed saying it makes no sense to take drugs or do anything, then we cannot help. That is for us, I think, the most important thing. We’ve seen it now in two trials,” according to the cardiologist.
The all-cause mortality rate was 7.86 per 100 person-years in the home-telemonitoring group versus 11.34 in usual-care controls. Patients in the active intervention arm lost a mean of 17.8 days per year because of unplanned cardiovascular hospital admissions, compared with 24.2 days per year in controls.
Importantly, outcomes were equally good in the remote patient-management group regardless of whether patients were among the 40% of participants living in urban Germany or the 60% in rural areas. Thus, the telemonitoring intervention eliminated the geographic disparity in health care outcomes which is a prominent issue in Germany, as well as the United States.
A formal cost-benefit analysis of the TIM-HF2 results is in the works, Dr. Koehler said.
Simultaneous with his presentation in Munich, the TIM-HF2 study was published online in the Lancet.
In an accompanying editorial, two prominent heart failure experts – John F.G. Cleland, MD, of the University of Glasgow and Robin A. Clark, MD, of Flinders University in Adelaide – hailed TIM-HF2 as a major advance and indicated in sharp terms that it’s time for guideline writers to sit up and take notice.
“Despite much clinical skepticism and feeble support from most guidelines, in our view the growing weight of evidence suggests that home telemonitoring does reduce mortality for patients with heart failure, and this effect might be substantial. These and other trials also show that the emphasis placed on hospital admission for heart failure might be misplaced, at least from a patient’s perspective, because the proportion of days lost due to hospital admission is small, compared with those lost to death,” the physicians wrote in the editorial.
They also noted that, even though the between-group difference in the number of days during which patients were hospitalized for cardiovascular causes was relatively small, it’s clear that home telemonitoring triggered some potentially life-saving hospitalizations. “Home telemonitoring puts the patient back in the center of health care, ensuring that they know what the health professional is trying to achieve and that they agree with those aims. Ultimately, patients and their families are a large and relatively untapped health care resource,” they wrote.
The TIM-HF 2 trial was funded by the German Federal Ministry of Education and Research. Dr. Koehler reported receiving speaking and/or consultant fees from Novartis, Abbott, and Medtronic.

Pulmonary artery denervation boosts walking capacity in left heart failure
SAN DIEGO – Pulmonary artery denervation is efficacious for treating combined pre- and postcapillary pulmonary hypertension attributable to left heart failure, based on results of the Chinese PADN-5 trial reported at the Transcatheter Cardiovascular Therapeutics annual meeting.
This ablative treatment has been studied among patients with pulmonary hypertension attributable to other etiologies, but not in randomized fashion among this population, noted lead investigator Shao-Liang Chen, MD, of Nanjing (China) First Hospital, Nanjing Medical University. The treatment is an attractive one, as medications recommended for pulmonary arterial hypertension are not recommended for joint pre- and postcapillary pulmonary hypertension (group II pulmonary hypertension).
In PADN-5, 98 patients were randomized to pulmonary artery denervation or to sham denervation plus open-label sildenafil (Viagra), which at the time of trial initiation was thought to be safe and potentially beneficial.
The trial’s main outcome, 6-minute walk distance at 6 months, improved in both groups, according to data reported at the meeting and simultaneously published in JACC Cardiovascular Interventions. But the improvement was about four times greater in the pulmonary artery denervation group. Secondary efficacy outcomes also favored that group, and the rate of fatal pulmonary embolism did not differ for the two groups.
“The PADN-5 trial demonstrates the benefits of pulmonary artery denervation for patients with combined pre- and postcapillary pulmonary hypertension. Patients with preserved and with reduced ejection fraction equally benefited,” summarized Dr. Chen, who pioneered this procedure about 7 years ago. “There was no sign of any harm of sildenafil in patients with combined pre- and postcapillary pulmonary hypertension.”
Trial critique
“This is a very difficult study to conduct, being able to recruit patients and actually have these procedures done,” commented press conference moderator Ori Ben-Yehuda, MD, professor of clinical medicine and director, coronary care unit, UC San Diego Medical Center.
At the same time, he expressed some reservations about the trial. “Sildenafil in the control group might actually be expected to ... decrease your effect size. Also, particularly in men, perhaps even in women, it might unblind them to which group they are in and undermine your sham design,” he noted. In addition, some hemodynamic changes after pulmonary artery denervation – a decrease in wedge pressure and an increase in ejection fraction – were puzzling.
“We need a lot more data here. There are some issues with this trial in terms of design, and we haven’t even gotten into the issue of whether there were core labs, whether the echoes, the hemodynamics, were read blindly,” Dr. Ben-Yehuda maintained. “This issue of secondary or group II pulmonary hypertension due to left heart failure is one that has been very frustrating in terms of actual PA-specific therapies. So this is an important step further, but it needs confirmation in truly sham-controlled trials that have no potential for unblinding.”
The catheter used in PADN-5 is available in China but has not received clearance in the United States, he pointed out. “There are alternative or competing technologies, one using ultrasound, for example, that has a very similar approach. … We’ll have to see how it ends up [performing].”
Trial details
Patients in the PADN-5 pulmonary artery denervation group underwent ablation only in the periconjunctional area between the distal main trunk and the left ostial branch with a multifunction catheter having premounted electrodes. Those in the control group underwent a sham procedure, with catheter positioning at the target sites and connection to a generator but no ablation, and were given open-label sildenafil. All additionally received standard heart failure medical therapy. (No sildenafil placebo was used in the denervation group.)
Trial results reported at the meeting, which is sponsored by the Cardiovascular Research Foundation, showed that most echocardiographic and hemodynamic measures improved more in the pulmonary artery denervation group.
The greater improvement in 6-minute walk test with denervation versus sham sildenafil at 6 months was evident in a variety of measures: absolute median distance walked (432.5 m vs. 358 m) and mean distance walked (434.6 m vs. 359.4 m), and absolute increase (80 m vs. 17.5 m) and relative increase (21.4% vs. 4.9%) The difference was significant for all measures at P less than .001.
The denervation group had a comparatively greater reduction of pulmonary vascular resistance (29.8% vs. 3.4%; P less than .001) and were less likely to experience clinical worsening (16.7% vs. 40.0%; P = .014).
There was a single fatal pulmonary embolism in each treatment group. Of the seven total deaths, two occurred in the denervation group (one attributable to pump failure, one a sudden death) and five occurred in the sham sildenafil group (all but one attributable to pump failure).
Dr. Chen disclosed that he had no relevant conflicts of interest. The trial was sponsored by Nanjing First Hospital, Nanjing Medical University.

In PADN-5, 98 patients were randomized to pulmonary artery denervation or to sham denervation plus open-label sildenafil (Viagra), which at the time of trial initiation was thought to be safe and potentially beneficial.
The trial’s main outcome, 6-minute walk distance at 6 months, improved in both groups, according to data reported at the meeting and simultaneously published in JACC Cardiovascular Interventions. But the improvement was about four times greater in the pulmonary artery denervation group. Secondary efficacy outcomes also favored that group, and the rate of fatal pulmonary embolism did not differ for the two groups.
“The PADN-5 trial demonstrates the benefits of pulmonary artery denervation for patients with combined pre- and postcapillary pulmonary hypertension. Patients with preserved and with reduced ejection fraction equally benefited,” summarized Dr. Chen, who pioneered this procedure about 7 years ago. “There was no sign of any harm of sildenafil in patients with combined pre- and postcapillary pulmonary hypertension.”
Trial critique
“This is a very difficult study to conduct, being able to recruit patients and actually have these procedures done,” commented press conference moderator Ori Ben-Yehuda, MD, professor of clinical medicine and director, coronary care unit, UC San Diego Medical Center.
At the same time, he expressed some reservations about the trial. “Sildenafil in the control group might actually be expected to ... decrease your effect size. Also, particularly in men, perhaps even in women, it might unblind them to which group they are in and undermine your sham design,” he noted. In addition, some hemodynamic changes after pulmonary artery denervation – a decrease in wedge pressure and an increase in ejection fraction – were puzzling.
“We need a lot more data here. There are some issues with this trial in terms of design, and we haven’t even gotten into the issue of whether there were core labs, whether the echoes, the hemodynamics, were read blindly,” Dr. Ben-Yehuda maintained. “This issue of secondary or group II pulmonary hypertension due to left heart failure is one that has been very frustrating in terms of actual PA-specific therapies. So this is an important step further, but it needs confirmation in truly sham-controlled trials that have no potential for unblinding.”
The catheter used in PADN-5 is available in China but has not received clearance in the United States, he pointed out. “There are alternative or competing technologies, one using ultrasound, for example, that has a very similar approach. … We’ll have to see how it ends up [performing].”
Trial details
Patients in the PADN-5 pulmonary artery denervation group underwent ablation only in the periconjunctional area between the distal main trunk and the left ostial branch with a multifunction catheter having premounted electrodes. Those in the control group underwent a sham procedure, with catheter positioning at the target sites and connection to a generator but no ablation, and were given open-label sildenafil. All additionally received standard heart failure medical therapy. (No sildenafil placebo was used in the denervation group.)
Trial results reported at the meeting, which is sponsored by the Cardiovascular Research Foundation, showed that most echocardiographic and hemodynamic measures improved more in the pulmonary artery denervation group.
The greater improvement in 6-minute walk test with denervation versus sham sildenafil at 6 months was evident in a variety of measures: absolute median distance walked (432.5 m vs. 358 m) and mean distance walked (434.6 m vs. 359.4 m), and absolute increase (80 m vs. 17.5 m) and relative increase (21.4% vs. 4.9%) The difference was significant for all measures at P less than .001.
The denervation group had a comparatively greater reduction of pulmonary vascular resistance (29.8% vs. 3.4%; P less than .001) and were less likely to experience clinical worsening (16.7% vs. 40.0%; P = .014).
There was a single fatal pulmonary embolism in each treatment group. Of the seven total deaths, two occurred in the denervation group (one attributable to pump failure, one a sudden death) and five occurred in the sham sildenafil group (all but one attributable to pump failure).
Dr. Chen disclosed that he had no relevant conflicts of interest. The trial was sponsored by Nanjing First Hospital, Nanjing Medical University.

Prosthesis-patient mismatch post TAVR ups death risk 19%
SAN DIEGO – Severe prosthesis-patient mismatch (PPM) after transcatheter aortic valve replacement (TAVR) increases risk of adverse outcomes and may be preventable in some cases with careful preprocedural planning, suggests a registry-based retrospective cohort study of 62,125 patients treated in the contemporary era.
The study – the largest to date of this patient population – determined that about one in every eight patients undergoing TAVR ultimately had a severe mismatch between the hemodynamics of the valve prosthesis and the requirements for cardiac output. Compared with counterparts that have moderate or no PPM, these patients with severe PPM had a 12% higher adjusted risk of heart failure rehospitalization and a 19% higher adjusted risk of death, according to results reported at the Transcatheter Cardiovascular Therapeutics annual meeting and simultaneously published online (J Am Coll Cardiol. 2018 Sep 23. doi: 10.1016/j.jacc.2018.09.001).
Notably, some of the predictors of severe PPM, such as use of smaller-diameter valves and performance of a valve-in-valve procedure, were potentially modifiable.
“Our findings suggest that efforts should be made to identify this problem and limit the risk for PPM after TAVR,” concluded lead investigator Howard C. Herrmann, MD, a professor at the University of Pennsylvania and director of the cardiac catheterization laboratories, Hospital of the University of Pennsylvania, both in Philadelphia. “Awareness is really the first step in trying to fix it.”
“We spend a lot of time in the heart-team meetings looking at the CT scans for annular dimensions and the vascular access, but we don’t really talk too much about severe PPM or the risk of that,” he elaborated. “This [study] allows us to start to predict it, based on patient factors and what prosthesis we might be choosing for a patient, and it allows us to have that conversation and think about alternatives.
“There are alternatives to try to avoid PPM, everything from which prosthesis we choose to the size of the prosthesis, to whether we fracture a patient’s valve if we are doing a valve-in-valve procedure. In the future, in some situations, we might even choose a low-risk or low-intermediate-risk patient for surgery with an enlargement operation in order to get a larger effective orifice area. So there are choices that we can make, and we should start thinking about that in the heart-team approach.”
Findings in context
The new study reinforces the message “that hemodynamics matter,” he said. “To the extent that we can get larger valves in and get better results from those valves, it will reduce the frequency of PPM. That’s something as operators we don’t spend as much time focusing on, and this will refocus our attention in trying to prevent PPM by being more diligent in terms of prosthesis choice and some operator characteristics, to try to reduce the gradients and improve the effective orifice areas as much as we can.”
Panelist Jeffrey J. Popma, MD, an interventional cardiologist at Beth Israel Deaconess Medical Center, Boston, noted that he and his colleagues have observed similar trends in their smaller studies but had difficulty teasing out contributors. “It really goes back to the preprocedural planning about what valve you can get in, and larger orifice area is certainly better,” he concurred. “So I do think that this is a phenomenal addition.”
Study details
For the study, Dr. Herrmann and his colleagues analyzed 2014-2107 data from the STS/ACC Transcatheter Valve Therapy Registry, a national surveillance and quality improvement system. They identified enrollees aged 65 years or older at the time of their TAVR procedure who had fee-for-service Medicare and linked them to Centers for Medicare & Medicaid Services claims data to assess outcomes.
Overall, 12.1% of patients had severe PPM, defined as an effective valve orifice area indexed to body surface area of less than 0.65 cm2/m2 on discharge echocardiography, and another 24.6% had moderate PPM, Dr. Herrmann reported at the meeting, sponsored by the Cardiovascular Research Foundation.
The strongest multivariate predictors of severe PPM were small prosthetic valve size (up to 23 mm in diameter) (odds ratio, 2.77), a valve-in-valve procedure (OR, 2.78), larger body surface area (OR, 1.71 per 0.2-U increase), and female sex (OR, 1.46). Odds also increased with decreasing age and were elevated for patients of nonwhite/Hispanic race and those having a lower ejection fraction, atrial fibrillation or flutter, or severe mitral or tricuspid regurgitation.
It was not possible to assess specific valves as predictors of mismatch because the registry prohibits comparisons across manufacturers, according to Dr. Herrmann.
One-year mortality, the study’s primary endpoint, was 17.2% in patients with severe PPM, compared with 15.8% in patients with moderate or no PPM (adjusted hazard ratio, 1.19; P less than .001). Findings were similar across subgroups.
The 1-year rate of heart failure rehospitalization was 14.7% in patients with severe PPM, compared with 12.2% in patients with moderate or no PPM (AHR, 1.12; P = .017).
“I would point out that these [outcome] curves are divergent at 1 year,” Dr. Herrmann noted. “So if we look at low-intermediate-risk and low-risk patients and younger patients, who may be more active and who see the effects of PPM more commonly and who are going to be living more than 1 year, we are going to have to consider this going forward in a more important way.”
Severe PPM did not significantly influence the rate of stroke (which stood at about 4% in each group) or worsen quality of life score at 1 year.
Dr. Herrmann disclosed receiving institutional grant/research support from Abbott Vascular, Bayer, Boston Scientific, Corvia Medical, Edwards Lifesciences, Medtronic, and St. Jude Medical, as well as consulting fees/honoraria from Edwards, Medtronic, and Siemens Healthineers.

Novel device improves mitral regurgitation 30% in REDUCE-FMR
SAN DIEGO – In patients with heart failure and functional mitral regurgitation, implantation of an investigational device led to reduced MR and improved left ventricular remodeling at 1 year, compared with patients who received sham treatment in the REDUCE-FMR trial.
The device showed promise in this trial, despite a small sample size, and its nature makes it possible to follow up with other procedures if the disease progresses. “The advantage of this technique is that all other options are still open,” Horst Sievert, MD, director of the CardioVascular Center in Frankfurt, said during a press conference at the Transcatheter Cardiovascular Therapeutics annual meeting.
The Carillon Mitral Counter System includes two anchors, one in the great cardiac vein and one in the coronary sinus, connected by a shaping ribbon. The tension of the ribbon bolsters the mitral annulus, which in turn reduces mitral regurgitation.
REDUCE-FMR recruited 120 patients from centers in eight countries and randomized 87 to the Carillon device (73 implanted) and 33 to a sham procedure. Sham patients were sedated and received a coronary sinus angiogram. Patients were included if they had dilated ischemic or nonischemic cardiomyopathy and moderate to severe functional MR, among other requirements. Exclusion criteria included existing coronary artery stents in the implant target zone, severe mitral annular calcification, and significant organic mitral valve pathology.
The primary endpoint was the mean reduction of regurgitant volume at 1 year. The treated patients had a 22% reduction of 7.1 mL, while the sham group on average had an 8% increase of 3.3 mL (P = .03). In the as-treated subpopulation, which comprised 45 patients in the treatment group and 13 controls, the values were –7.5 mL and +3.3 mL (P = .02). A per-protocol analysis, which excluded patients who did not meet protocol criteria, led to an amplification of the effect when the study design was adhered to (–12.5 mL vs. +1.3 mL), though this result did not achieve statistical significance owing to the small sample size.
For the safety endpoints, the researchers examined the frequency of major adverse events (MAE), including death, myocardial infarction, cardiac perforation, device embolism, and surgery or percutaneous coronary intervention related to the device at 1 year. In the treatment group, 16.1% experienced a MAE, compared with 18.2% of control patients, a statistically nonsignificant difference.
A secondary efficacy endpoint of change in left ventricular end-diastolic volume showed improvements in the treatment group at 6 months (–12.4 mL) and 12 months (–8.6 mL), compared with increases in the sham group at 6 months (+5.4 mL) and 12 months (+6.5 mL). A similar trend occurred in left ventricular end-systolic volume (–7.8 mL and –4.8 mL; +3.4 mL and +6.1 mL, respectively).
The study was conducted in a patient population similar to that of the COAPT trial, which examined implantation of Abbott’s MitraClip. That study, presented here at TCT 2018 and simultaneously published in the New England Journal of Medicine, also examined patients with heart failure and secondary MR.
However, in REDUCE-FMR, many of the patients had milder heart failure than the researchers had expected: 44.8% in the treatment group had NYHA class II, as did 48.5% in the sham group. That surprise may help identify an appropriate patient population. “I think this device may have a nice spot in between medical therapy and MitraClip implantation, because we have, by chance, a patient population with mild heart insufficiency and mild MR,” said Dr. Sievert.
The two devices also showed different physiologic effects, Michael Mack, MD, said at a press conference. “One subtle difference is that, in this trial, the difference is due to both positive left ventricular remodeling in the treatment arm and continued progression in the sham control. In COAPT, the difference in improvement that we saw was totally due to prevention of progression of disease. We just stabilized the disease to where it was at. So that’s an intriguing difference here, that you actually were able to demonstrate positive left ventricular remodeling,” noted Dr. Mack, medical director for cardiovascular surgery at Baylor Scott & White Medical Center, Plano, Tex. He was a coinvestigator in the COAPT trial.
REDUCE-FMR was funded by Cardiac Dimensions. Dr. Sievert has received consulting fees, travel expenses, and study honoraria from Cardiac Dimensions, and 35 other companies. Dr. Mack has received grant support or had a research contract with Abbott Vascular, Medtronic, and Edwards Lifesciences.

For the safety endpoints, the researchers examined the frequency of major adverse events (MAE), including death, myocardial infarction, cardiac perforation, device embolism, and surgery or percutaneous coronary intervention related to the device at 1 year. In the treatment group, 16.1% experienced a MAE, compared with 18.2% of control patients, a statistically nonsignificant difference.
A secondary efficacy endpoint of change in left ventricular end-diastolic volume showed improvements in the treatment group at 6 months (–12.4 mL) and 12 months (–8.6 mL), compared with increases in the sham group at 6 months (+5.4 mL) and 12 months (+6.5 mL). A similar trend occurred in left ventricular end-systolic volume (–7.8 mL and –4.8 mL; +3.4 mL and +6.1 mL, respectively).
The study was conducted in a patient population similar to that of the COAPT trial, which examined implantation of Abbott’s MitraClip. That study, presented here at TCT 2018 and simultaneously published in the New England Journal of Medicine, also examined patients with heart failure and secondary MR.
However, in REDUCE-FMR, many of the patients had milder heart failure than the researchers had expected: 44.8% in the treatment group had NYHA class II, as did 48.5% in the sham group. That surprise may help identify an appropriate patient population. “I think this device may have a nice spot in between medical therapy and MitraClip implantation, because we have, by chance, a patient population with mild heart insufficiency and mild MR,” said Dr. Sievert.
The two devices also showed different physiologic effects, Michael Mack, MD, said at a press conference. “One subtle difference is that, in this trial, the difference is due to both positive left ventricular remodeling in the treatment arm and continued progression in the sham control. In COAPT, the difference in improvement that we saw was totally due to prevention of progression of disease. We just stabilized the disease to where it was at. So that’s an intriguing difference here, that you actually were able to demonstrate positive left ventricular remodeling,” noted Dr. Mack, medical director for cardiovascular surgery at Baylor Scott & White Medical Center, Plano, Tex. He was a coinvestigator in the COAPT trial.

COAPT: MitraClip prolongs life in selected HF patients
SAN DIEGO – Among a carefully selected subset of heart failure patients and severe secondary mitral regurgitation, transcatheter mitral valve repair with the MitraClip reduced hospitalizations for heart failure by 47%, and death from any cause by 38% over 24 months, compared with maximal medical therapy alone.
That’s according to a randomized, open-label trial presented at the Transcatheter Cardiovascular Therapeutics annual meeting.
The number needed to treat to prevent one heart failure (HF) hospitalization within 2 years was three; the number needed to treat to save one life was six. Only about 3% of patients had a device complication within 12 months of placement in the study, dubbed COAPT (the Heart Failure Patients with Functional Mitral Regurgitation Trial).
COAPT patients had grade 3+ or 4+ secondary mitral regurgitation, with a mean effective regurgitant orifice area (EROA) of 41 mm2. Their left ventricles were dilated, but not huge, with a mean left ventricular end-diastolic volume of 101 mL/m2. “We estimate that’s about 10% of heart failure patients,” said lead investigator and interventional cardiologist Gregg W. Stone, MD, a professor of medicine at Columbia University, New York.
MitraClip placement was performed in high-volume centers by experienced operators, and patients were on maximally tolerated doses of guideline-directed medical therapy, as per the 2013 American College of Cardiology/American Heart Association heart failure management guidelines. There was very little variation in treatment regimens during the 2-year trial (J Am Coll Cardiol. 2017;70:776-803).
Those parameters matter. Among HF patients who did not fit them in the recent Mitra-FR trial in France, MitraClip did not reduce rates of death or unplanned hospitalization (N Engl J Med. 2018 Aug 27. doi: 10.1056/NEJMoa1805374).
COAPT and Mitra-FR investigators said at the meeting that the studies are complimentary, not conflicting, because together, they define secondary mitral regurgitation (MR) patients who will and will not benefit from the device.
MR was less severe in Mitra-FR, with a mean EROA of 31 mm2, but left ventricles were more dilated, with a mean left ventricular end-diastolic volume of 135 mL/m2. Patients were on more real-world drug regimens that varied over the course of the trial. Also, the lower implantation rates and higher complication rates in Mitra-FR “suggests perhaps greater experience of the COAPT operators,” said Dr. Stone, who also is the director of cardiovascular research and education at the Center for Interventional Vascular Therapy at New York-Presbyterian Hospital/Columbia University Medical Center.
In short, “they were a different patient population than were enrolled in COAPT,” he said at the meeting, sponsored by the Cardiovascular Research Foundation, which Dr. Stone also codirects.
There was great excitement at TCT about COAPT because there was a startling benefit for patients who previously had few options. But many speakers worried that the hype surrounding the trial will drown out the critically important message about patient selection and that the clip will be used in HF patients who don’t fit the COAPT profile.
They also said that the emerging picture of benefit in patients with less ventricular dilation but more mitral regurgitation needs to be fleshed out and better quantified.
COAPT randomized 302 patients to MitraClip on a background of guideline-directed therapy and 312 to guideline-directed therapy alone. Participants who had mitral regurgitation caused by left ventricular dysfunction, were not surgical candidates, and remained symptomatic despite optimal treatment.
The annualized rate of all hospitalizations for HF within 24 months was 35.8% per patient-year in the device group, as compared with 67.9% per patient-year in the control group, for a relative reduction of 47% (P less than .001).
Death from any cause within 24 months occurred in 29.1% of the patients in the device group and 46.1% in the control group, yielding a reduction of 38% (P less than .001).
“We didn’t cure patients by fixing their MR. They still had 29% 2-year mortality, but we did markedly improve their quality of life. The only subgroup that didn’t benefit were patients that had an EORA of less than 30 mm2 and end diastolic volume greater than the median” of 96 mL/m2, which was “fascinating,” Dr. Stone said, and fit the emerging picture.
Mitral regurgitation grade fell to 1+ or lower in 82% of patients after clip placement and remained there in the majority of survivors at 2 years.
For a long time, “HF experts thought MR was just a marker of severe left ventricular dysfunction. What I think we see here is that secondary MR is not just a bystander. It contributes to the abnormal pathophysiology of these patients,” he said.
The trial was sponsored by MitraClip’s maker, Abbott. The company participated in site selection, management, and data analysis. Dr. Stone disclosed that his employer, Columbia University, receives royalties from Abbott for sale of the clip. Several fellow investigators disclosed grants, fees, and other financial ties to the company.
Simultaneously with the COAPT presentation, the results were published online (N Engl J Med. 2018 Sep 23. doi: 10.1056/NEJMoa1806640).
Mitra-FR was funded by the French Ministry of Health and Research and Abbott.
This is really a blockbuster trial, because you see a statistically significant reduction in cardiovascular endpoints, which is something we almost never see in device-based trials. I think this is going to change clinical practice, but the question of generalizability is tricky. This was such a well-conducted trial; it may be difficult to generalize this to the practicing public. I was impressed by the MitraClip performance: the reduction in MR [mitral regurgitation], the lack of recurrence, and the small number of complications. Perhaps more than anything else, the difference between Mitra-FR and COAPT was the quality of the operators.

Leon, MD , is the director of the Center for Interventional Vascular Therapy at Columbia University, N.Y., and the Cardiovascular Research Foundation’s founder and codirector of medical research and education.
