摘要

We report the case of a 71-year-old man hospitalized for acute heart failure. Transthoracic and transesophageal echocardiography showed mitral valve aneurysm (MVA) rupture and severe mitral regurgitation. No vegetations but significant aortic regurgitation were also observed. MVA perforation is a rare life-threatening condition that typically occurs as a complication of endocarditis but may also be associated with other diseases, in particular connective tissue disorders. In the present case, the absence of such etiology suggests a possible role for of aortic regurgitation in MVA rupture secondary to a "jet lesion" mechanism.
