Pulmonary arterial hypertension (PAH) is characterized by pulmonary vasoconstriction and vascular remodeling, leading to increased pulmonary vascular resistance, pathological right ventricular (RV) remodeling, and ultimately right heart failure and death. 

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.
