Abstract:
Evidence regarding redo percutaneous interventions for recurrent mitral regurgitation is scarce. We ought to evaluate procedural and clinical outcomes of repeated edge‐to‐edge transcatheter mitral valve repair (TMVR) interventions. Methods This multicenter study collected individual data from eight high‐volume TMVR Centers in Spain. Between 2012 and 2020, all patients undergoing a second edge‐to‐edge TMVR intervention (Redo) were included in the study. Results Among a total of 1028 procedures, 31 patients (3%) with residual MR ≥ 3 at follow‐up underwent a second procedure (Redo). Redo intervention was mainly conducted between the first and second year after the first procedure. The most common cause of MR progression was partial detachment (46.7%) followed by LV remodeling (35.5%). Procedural success was achieved in 87% of cases. After a mean follow‐up of 1.75 ± 1.54 years, all‐cause and cardiovascular mortality were 48.1% and 25%, respectively. Nearly half of the patients (48.1%) required at least one hospital admission for CHF within the follow‐up period. However, most of the patients presented symptomatic improvement as depicted by an NYHA class ≤2. Elective mitral surgery was conducted in only one patient at follow‐up due to insufficient MR reduction. Conclusions According to our findings, redo edge‐to‐edge TMVR interventions were feasible and safe with a high procedural success rate. Clinical and echocardiographic follow‐up showed however modest long‐term results in this specific setting.
