Objectives: The aim of this study was to assess the pooled clinical and echocardiographic outcomes of different isolated transcatheter tricuspid valve repair (ITTVR) strategies for significant (moderate or greater) tricuspid regurgitation (TR). Background: Significant TR is a common valvular heart disease worldwide. Methods: Published research was systematically searched for studies evaluating the efficacy and safety of ITTVR for significant TR in adults. The primary outcomes were improvement in New York Heart Association (NYHA) functional class and 6-minute walking distance and the presence of severe or greater TR at the last available follow-up of each individual study. Random-effect meta-analysis was performed comparing outcomes before and after ITTVR. Results: Fourteen studies with 771 patients were included. The mean age was 77 ± 8 years, and the mean European System for Cardiac Operative Risk Evaluation II score was 6.8% ± 5.4%. At a weighted mean follow-up of 212 days, 209 patients (35%) were in NYHA functional class III or IV compared with 586 patients (84%) at baseline (risk ratio: 0.23; 95% CI: 0.13-0.40; P < 0.001). Six-minute walking distance significantly improved from 237 ± 113 m to 294 ± 105 m (mean difference +50 m; 95% CI: +34 to +66 m; P < 0.001). One hundred forty-seven patients (24%) showed severe or greater TR after ITTVR compared with 616 (96%) at baseline (risk ratio: 0.29; 95% CI: 0.20-0.42; P < 0.001). Conclusions: Patients undergoing ITTVR for significant TR experienced significant improvements in NYHA functional status and 6-minute walking distance and a significant reduction in TR severity at mid-term follow-up.

Abstract

Objectives: The aim of this study was to assess the pooled clinical and echocardiographic outcomes of different isolated transcatheter tricuspid valve repair (ITTVR) strategies for significant (moderate or greater) tricuspid regurgitation (TR). Background: Significant TR is a common valvular heart disease worldwide. Methods: Published research was systematically searched for studies evaluating the efficacy and safety of ITTVR for significant TR in adults. The primary outcomes were improvement in New York Heart Association (NYHA) functional class and 6-minute walking distance and the presence of severe or greater TR at the last available follow-up of each individual study. Random-effect meta-analysis was performed comparing outcomes before and after ITTVR. Results: Fourteen studies with 771 patients were included. The mean age was 77 ± 8 years, and the mean European System for Cardiac Operative Risk Evaluation II score was 6.8% ± 5.4%. At a weighted mean follow-up of 212 days, 209 patients (35%) were in NYHA functional class III or IV compared with 586 patients (84%) at baseline (risk ratio: 0.23; 95% CI: 0.13-0.40; P < 0.001). Six-minute walking distance significantly improved from 237 ± 113 m to 294 ± 105 m (mean difference +50 m; 95% CI: +34 to +66 m; P < 0.001). One hundred forty-seven patients (24%) showed severe or greater TR after ITTVR compared with 616 (96%) at baseline (risk ratio: 0.29; 95% CI: 0.20-0.42; P < 0.001). Conclusions: Patients undergoing ITTVR for significant TR experienced significant improvements in NYHA functional status and 6-minute walking distance and a significant reduction in TR severity at mid-term follow-up.
