Mitral valve aneurysm is a rare abnormality whose pathophysiology is poorly understood. It is defined as a bulge of the mitral valve leaflet toward the left atrium. Aneurysm in the posterior leaflet is exceptional. We report the case of a 26-year old man, who had been followed up for rheumatic aortic regurgitation for 4-years, hospitalized for febrile syndrome associated with episodes of left heart failure. Transthoracic echocardiographic examination (TTE) and transesophageal echocardiography (TEE) showed aortic valve vegetations with wide aneurysm of the small mitral valve associated with severe mitral valve regurgitation. The patient underwent mitral and aortic valve replacement with simple postoperative outcome. Clinical suspicion associated with suitable preoperative imaging and early surgical treatment are essential to recognize and treat this rare complication of infectious endocard.
