Mitral Stenosis Caused by an Amplatzer Occluder Device Used to Treat a Paravalvular Leak
ABSTRACT Paravalvular leaks following valve replacement can result in heart failure and hemolysis. Surgical intervention is the treatment of choice, but it carries substantial risk of morbidity and mortality. Percutaneous techniques using devices designed for congenital heart disease are increasingly applied to the treatment of paravalvular leaks. We present the case of a mitral paravalvular leak treated with an Amplatzer occluder device. Unfortunately, the device occluded flow through the mitral valve, resulting in symptomatic mitral stenosis requiring surgical intervention.

ABSTRACT: A large mitral paravalvular leak in a 63-year-old patient was closed by percutaneous placement of 2 Amplatzer Septal Occluder (AGA Medical Corporation, Plymouth, MN) devices. The patient had a residual paravalvular leak and subsequently developed infective endocarditis that was successfully treated by removal of all hardware and implantation of a new valve. Transcatheter treatment of paravalvular leaks may be useful in select patients who are poor candidates for open surgery; however, one must be aware of the potential complications. This report underscores the risk of device infection that may be increased if there is turbulence related to residual paravalvular leaks.The Annals of thoracic surgery 05/2013; 95(5):1787-9.
