Percutaneous Paravalvular Leak Repair

Abstract

Paravalvular leaks (PVLs) are challenging lesions that require a comprehensive understanding of surgical and transcatheter heart therapies, multimodality imaging, and transcatheter techniques. Approach to a transcatheter heart valve (THV) or surgical prosthesis for PVL differs in terms of options and varies according to the location (aortic or mitral). A suggested framework for transcatheter PVL repair is defect localization, access planning, defect crossing, sheath delivery. and occluder deployment. Careful planning facilitates success, but operators begin the case with a flexible mindset because many initial strategies may not succeed.
