Objectives. Our aim was to adapt the technique of transcatheter umbrella closure of
intracardiac defects for closure of valvular and paravalvular defects. Background. The …

Background: Paravalvular leak (PVL) occurs in 5% to 17% of patients following surgical
valve replacement. Percutaneous device closure represents an alternative to repeat surgery …

Paravalvular regurgitation affects 5% to 17% of all surgically implanted prosthetic heart
valves. Patients who have paravalvular regurgitation can be asymptomatic or present with …

Abstract Background: Paravalvular leaks (PVLs) are a well‐recognized complication of
prosthetic valve replacement. Most are asymptomatic and benign, but some may cause …

Objectives: The aim of this study is to provide a summary of the currently applied aortic
paravalvular leak (PVL) closure techniques and describe the procedural and long-term …

Objectives: This study sought to describe a method of paravalvular leak closure using a
purpose-specific occlusion device. Background: Transcatheter closure of paravalvular leaks …

Aims: The aim of the study was to assess the safety and efficacy of percutaneous closure of
paravalvular prosthetic leak (PVL) and to identify the predictors of procedural success and …

Following aortic valve replacement, up to 5% of patients may develop clinically significant
paravalular leaks. Reoperation is associated with higher mortality and an excess risk of …

Objectives: The purpose of this study was to evaluate the feasibility and efficacy of the
percutaneous device closure of a consecutive series of patients with periprosthetic …

Aims: The purpose of this study was to evaluate the feasibility and short-term efficacy of
transcatheter paravalvular leak closure using different occlusion devices. Methods and …
