Percutaneous paravalvular leak closure for balloon-expandable transcatheter aortic valve replacement: a comparison with surgical aortic valve replacement paravalvular leak closure.

Paravalvular leak (PVL) is frequently observed after transcatheter aortic valve replacement (TAVR) and is related to increased mortality. Percutaneous PVL closure, which is a viable option for this complication, has been performed following surgical aortic valve replacement (SAVR); however, the experience in TAVR remains limited. We sought to compare this technique between post-TAVR and post-SAVR cases.A single-center series of patients...
