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.
