Transcatheter Tricuspid Valve Intervention in Patients with Previous Left Valve Surgery.

Abstract Background Scarce data exist on patients with previous left valve surgery (PLVS) undergoing transcatheter tricuspid valve intervention (TTVI). Objectives This study sought to investigate the procedural and early outcomes in patients with PLVS undergoing TTVI. Methods This was a sub-analysis of the multicenter TriValve registry including 462 patients, 82 (18%) with PLVS. Data were analyzed according to the presence of PLVS in the overall cohort and in a propensity score-matched population including 51 and 115 patients with and without PLVS, respectively. Results Patients with PLVS were younger (72±10 vs. 78±9 years, p Conclusions In patients with PLVS, TTVI was associated with high rates of procedural success and low early mortality. However, about one third of patients required rehospitalization or died at midterm follow-up. These results would support TTVI as a reasonable alternative to redo-surgery in patients with PLVS, and suggest the importance of earlier treatment in order to improve clinical outcomes.
