Abstract

Papillary muscle rupture is a rare and life-threatening complication of acute myocardial infarction (AMI). We present a unique case of double papillary muscle rupture in a patient with three vessel disease and acute thrombotic occlusion of left circumflex obtuse marginal artery as the culprit lesion. (Level of Difficulty: Beginner.).

Keywords: AMI, acute myocardial infarction; IABP, intra-aortic balloon pump; OM1, left circumflex obtuse marginal artery; echocardiography; myocardial infarction; papillary muscles.
