Echocardiographic and invasive RV-PA coupling predict mortality after edge-to-edge repair for degenerative mitral regurgitation, while pulmonary artery pulsatility index does not: a single-center observational study
RV-PA coupling, but not PAPi, predicts mortality and heart failure rehospitalization following M-TEER in DMR patients. These findings highlight the value of RV-PA coupling indices for risk stratification and support their routine use in preprocedural assessment.
