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.
