Transcatheter para mitral annular ring leak device closure - A case report

Para mitral annular ring leakage can occur following ring dehiscence after mitral annuloplasty. Percutaneous device closure of para-annular ring leakage can be performed successfully to treat such regurgitations with good transesophageal echocardiography guidance and patient selection. While para valvular device closure has been described in the medical literature, there have been few anecdotal reports published on para ring leak device closures. In this case, we highlight our experience from the successful closure of a para mitral annular ring closure with an AVP III device. The patient had a para annular ring regurgitation post coronary artery bypass grafting with mitral ring annuloplasty presenting with hemolytic anemia and acute renal failure, successfully treated by percutaneous device closure.

Learning objective: This report describes the safety and effectiveness of a transcatheter para ring leak closure with an AVP III device. We applied the principles of device closure of paravalvular leak from our experience and related data from literature for this case and describe various hardware and techniques used for a successful closure of a para mitral ring leak.
