Paravalvular Leakages after Surgical Aortic-Valve Replacement and after Transcatheter Aortic-Valve Implantation: Strategies to Increase the Success Rate of Percutaneous Closure.

J Clin Med 2022 May 25;11(11). Epub 2022 May 25.

Interventional Cardiology Department, Centro Cardiologico Monzino, Istituto di Ricovero e Cura a Carattere Scientifico (IRCCS), 20138 Milan, Italy.

Moderate to severe paravalvular-leak (PVL) regurgitation after surgical aortic-valve replacement or after transcatheter valve implantation represents a well-known complication associated with symptoms related to heart failure, hemolysis, or both in patients with multiple comorbidities and with poor prognostic outcomes. The transcatheter closure of aortic paravalvular leaks (APVLs) is currently considered a valid alternative to cardiac surgery. Nevertheless, careful patient selection, optimal cardiac imaging for intraprocedural guidance, and expert operators are key for success. Read More
