My Approach to Assessment of Mitral Paraprosthetic Leak

Abstract

Mitral paraprosthetic leak is a common, often asymptomatic condition. When presented with clinical manifestations such as heart failure and/or hemolysis, interventional treatment is indicated. The transcatheter approach has become increasingly popular, requiring careful planning using imaging methods, particularly echocardiography. Echocardiography is crucial for assessing the severity, location, size, shape, and number of leaks. Once these variables are determined, the treatment approach is planned, typically using the transseptal route. The optimal puncture site depends on various factors, with precise puncture location being paramount. Intraoperative echocardiographic evaluation is essential for procedure success, guiding device positioning and adjustments while also identifying any potential complications.
