    Abstract:
    A 71-year old man presented with partial rupture progressing to complete rupture of the left ventricular anterior papillary muscle after acute anterolateral myocardial infarction. The progressive rupture was demonstrated by transthoracic and transesophageal echocardiography. Transthoracic echocardiography showed exaggerated systolic prolapse of the anterior mitral leaflet with grade III mitral regurgitation and partial disruption of the anterolateral papillary muscle, but transesophageal echocardiography during surgery disclosed the progression of the partial rupture to complete rupture. The flail anterior mitral leaflet with severe mitral regurgitation and the head of the ruptured papillary muscle into the left atrium in systole were confirmed. The patient was treated by coronary artery bypass grafting and mitral valve prosthesis using a St. Jude Medical valve with good outcome.
