Papillary Muscle Rupture (PMR) is a rare complication (0.5-5%) with high mortality that usually occurs two to seven days after Acute Myocardial Infarction (AMI). However, rapid diagnosis and concomitant treatment can improve early and long-term outcomes. We describe a rare PMR occurring immediately after AMI. The patient complained of exertional chest pain and dyspnea in cardiogenic shock, and was diagnosed with acute PMR by echocardiography. Electrocardiogram showed STsegment elevation in inferior leads, and the time course of creatinine kinase elevation indicated early onset of AMI. Herein, we describe an unusual PMR immediately after AMI and further review PMR.
