[Perforated mitral valve aneurysm as a rare course of bacterial endocarditis]

Abstract

A 65 year old man with a history of mechanical aortic valve replacement acquired Enterococcus faecalis mediated infective endocarditis about 3 years later. Transesophageal echocardiography revealed formation of an aneurysm confined to the anterior mitral valve leaflet. The aortic valve revealed no signs of endocarditis by transesophageal ultrasound. With sudden perforation of the mitral valve aneurysm, subsequent hemodynamic deterioration and pulmonary oedema, the patient underwent emergency mitral and aortic valve replacement. The postoperative course was uneventful.
