  ABSTRACT: Although necrosis of the left ventricular papillary muscles during acute myocardial infarction is common, rupture of the anterolateral papillary muscle due to occlusion of high lateral branch is rare. We present a rare case of anterolateral papillary muscle rupture caused by occlusion of a high lateral branch of the left coronary artery. Although the patient was in cardiogenic shock on admission, she was successfully treated by emergency mitral valve replacement after percutaneous catheter intervention and intra-aortic balloon pumping support. This case implies that the anterolateral papillary muscle can have a single blood supply and that it can be ruptured by an occlusion of a high lateral branch. Prompt diagnosis, immediate mechanical stabilization and aggressive surgical treatment are essential to save this group of patients.
