Perforated mitral valve aneurysm in the posterior leaflet without infective endocarditis

Abstract

Aneurysm of the mitral valve, although uncommon, occurs most commonly in association with infective endocarditic of the aortic valve and true mitral valve aneurysm is a rare cause of mitral regurgitation. We report a case with perforated mitral valve aneurysm in the posterior leaflet without concurrent infective endocarditic initially mistaken diagnosis of cystic mass, which was confirmed at operation with successful mitral valve annuloplasty. © 2012 Korean Society of Echocardiography.
