Percutaneous devices for the treatment of complex native valve mitral leaflet and aortomitral continuity defects: Review and case series (original) (raw)

Cardiovascular Revascularization Medicine

Abstract

Percutaneous closure of paravalvar leaks (PVLs) was once only performed in extreme or non-surgical risk cases not suitable for redo-surgery with tissue or mechanical valves. This technique is now the treatment of choice with long term outcomes that are better than redo operations.123 As interventionalists become more familiar with using PVL devices, more off label device use has been reported in non-surgical cases involving complex native mitral valve regurgitation (NVMR). In this review, we appraise the literature regarding percutaneous treatment of paravalvar leaks and more recently esoteric off label use. We also describe two recent challenging cases where percutaneous devices were used to treat severe leaks that developed as a sequela of previous infective endocarditis. We also provide specific recommendations regarding periprocedural strategy and focus on the importance of device choice to provide an optimal outcome.
