Abstract
Mitral valve aneurysm; defined as a bulge of the mitral valve leaflet toward the left atrium is a rare abnormality whose pathophysiology is poorly understood. The weakened aneurysmal wall may rupture and may cause severe mitral regurgitation and life-threatining conditions. In this case report we present a case of mitral anterior leaflet aneurysm rupture in a patient with immun deficiency and chronic renal failure.
