AIMS The aim of this study was to determine the impact of tricuspid regurgitation (TR) on mortality after edge-to-edge percutaneous mitral valve repair (PMVR), and also to analyse whether there is a difference in outcome between patients with improvement of TR after PMVR compared to patients without. METHODS AND RESULTS Out of 197 consecutive patients who underwent PMVR, 139 patients with available follow-up (mean 428±386 days) were included in the study. Concomitant moderate/severe TR was present in 58.3% of patients. Kaplan-Meier analysis showed significantly reduced overall survival for patients with moderate/severe TR, compared to patients with none/mild TR (p=0.003). Cox multivariate regression analysis revealed severe TR at baseline as the strongest independent predictor of mortality (HR 4.367, p=0.003). An improvement of the baseline moderate/severe TR was observed in 45.5% of patients at 30-day follow-up. Patients with no improvement of TR after PMVR had a higher midterm mortality compared to patients in whom TR improved (40.5% versus 11.4%, p=0.005). CONCLUSIONS More than half of patients undergoing PMVR have concomitant moderate/severe TR, which is associated with a worse outcome. Among predictors of mortality after edge-to-edge PMVR, severe TR at baseline is the most important. Patients with no improvement of TR at 30 days after PMVR have a significantly higher mortality at follow-up.
