While these cutoffs are straightforward, a gap in practical application is evidenced by considerable variability in how PH providers perform and interpret RHC hemodynamic information.
A recent survey of 145 PH providers conducted by CHEST’s Pulmonary Vascular Disease Section shed light on the current RHC practices in the US.2 Regarding the respondents’ characteristics, 85% were in the 30-60 age range, 68% were males, and 71% were pulmonologists.
About half of the providers perform the RHC themselves. Most review the hemodynamic tracings, but up to 21% rely on the final report alone. Regarding PCWP, most (86%) obtain it during end-expiration, but only 42% routinely measure a PCWP saturation for confirmation. When faced with PVR discrepancies between thermodilution and indirect Fick (IFick), up to 30% chose either IFick or didn’t know which one to trust. Nearly 20% repeat the RHC at least annually, and 80% whenever the patient declines.
This study provides the largest reported data on real-world RHC practices by PH physicians in the US. We found significant variability in hemodynamic interpretation. Standardization of RHC performance and hemodynamic evaluation is crucial to ensure appropriate PH management.
