Percutaneous Paravalvular Leak Closure.

چکیده
Symptomatic paravalvular leak (PVL) complicates up to 12 % of surgical valve replacements. When patients present with congestive heart failure and/or haemolysis, reoperation for repeat valve replacement may be undertaken, but presents greater risk and lower likelihood of success than the initial operation. Therefore, percutaneous approaches to PVL closure have been developed by specialists in structural cardiac intervention. Large series demonstrate high levels of procedural success and promising clinical outcomes for this complex intervention. A thorough understanding of multimodality imaging is necessary for the diagnosis of PVL and the safe and successful performance of these closure procedures.

Bioprosthetic leaflet erosion after percutaneous mitral paravalvular leak closure.
Davis nline ranscatheter closure of prosthetic paravalvular eaks is increasingly performed at experienced enters (1–3). The lack of devices dedicated to aravalvular leak closure has not deterred the ff-label use of various occluder devices. These mages illustrate the potential complexity of ranscatheter paravalvular leak repair with the eed for additional occluder placement, and the evelopment ...

Paravalvular leak (PVL) is a complication observed in patients after prosthetic valve replacement. The incidence of PVL is estimated as 2-3%. The cause of PVL may be paravalvular infection, suture continuity disruption, damage of tissues around the annulus or limitation of disc mobility by thrombus or vegetation. The preferable method of treatment of PVL is surgery. Recently, percutaneous closu...

Percutaneous closure of paravalvular leaks has emerged as an alternative to repeated surgeries. Different percutaneous techniques and various devices have been used, off-label, for paravalvular leak closure. For mitral leaks, antegrade transseptal, retrograde transfemoral, and retrograde transapical techniques have been developed. In the antegrade transseptal approach, an arteriovenous guidewir...

INTRODUCTION AND OBJECTIVES Percutaneous paravalvular leak closure is a complex procedure with varying success rates; the lack of closure devices specifically designed for this purpose has hampered this technique. The characteristics of the Amplatzer Vascular Plug III appear to be well suited for paravalvular leak closures; however, the available data are limited to case reports or small series...
