Tricuspid valves surgeries are preferably performed fully endoscopically via right lateral mini-thoracotomy using extracorporeal circulation but without cardioplegic arrest (minimally invasive beating-heart tricuspid valve surgery [MIC-TVS]). Transcatheter edge-to-edge repair (TEER) is an increasingly performed alternative in patients with symptomatic tricuspid regurgitation (TR) at high surgical risk. Contemporary MIC-TVS and TEER outcomes have not been compared. The TRI-SCORE has been proposed as a risk stratification in TR patients. Therefore, the objective of this study was to compare clinical outcomes in patients with TR undergoing TEER versus MIC-TVS in an all-comers cohort and to stratify outcomes according to the TRI-SCORE.
This is a retrospective observational multicentre study of patients treated for TR with TEER using edge-to-edge repair (n=211) or isolated MIC-TVS beating-heart procedures (n=28) between 2016 and 2021.
Endpoints were all-cause mortality at 30 days and 1 year, grade of TR at discharge and 1 year, and all-cause mortality at 1 year, stratified by TRI-SCORE (<6 vs ≥6 points). Kaplan-Meier estimation was used for survival analyses, and curves were compared using the log-rank test.
