Background: Data regarding the safety and long-term effectiveness of percutaneous closure of paravalvular leak (PVL) after transcatheter aortic valve implantation (TAVI) are scarce.

Aims: This study aims to present a large multicentre international experience of percutaneous post-TAVI PVL closure.

Methods: All patients who underwent percutaneous post-TAVI PVL closure in 14 hospitals across Europe and North America between January 2018 and October 2022 were included.

Results: Overall, 45 patients (64% male) were enrolled. The median age was 80 years (75-84). Among them, 67% and 33% had self-expanding and balloon-expandable valve implantations, respectively. Baseline post-TAVI PVL was severe in 67% of cases and moderate in the rest. The time from index TAVI to PVL closure procedure was 16.1 (8.7-34.8) months. Most patients were in NYHA Class III and IV (73%) before the procedure, and 40% had referred hospitalisations for heart failure between TAVI and the PVL closure procedure. Successful PVL closure was achieved in 94%, reducing regurgitation to ≤mild in 91% and moderate in the rest. The Amplatzer Valvular Plug III was the most frequently used device (27 cases), followed by...
