Impact of Right Heart Catheterization and the 2022 ESC/ERS Definition of Pulmonary Hypertension in Patients With Mitral Regurgitation Undergoing Valve Repair/Replacement.

ABSTRACT: In patients with mitral regurgitation (MR), the role of invasive hemodynamics is not well defined. We evaluated the value of right heart catheterization (RHC) and the 2022 ESC/ERS pulmonary hypertension (PH) definition prior to a mitral valve procedure for the prediction of PH several months thereafter. We studied 274 patients (mean age 68 ± 11 years) with at least moderate MR (84% degenerative, 11% functional, 5% combined) undergoing RHC (baseline) followed by surgical (70%) or transcatheter (30%) valve repair/replacement who had an echocardiogram after a median follow-up of 3 months. PH was defined as a mean pulmonary artery pressure (mPAP) > 20 mmHg and was subclassified by mean pulmonary artery wedge pressure (mPAWP) and pulmonary vascular resistance (PVR). The PH follow-up probability
