Abstract

A 61-year-old man presented with chest pain and ST elevation, and he underwent coronary angiography under the impression of acute myocardial infarction. Coronary intervention under intra-aortic balloon pumping was necessary due to his hemodynamic instability from the acute total occlusion of a large obtuse marginal branch. In spite of successful intervention, the cardiogenic shock persisted, and so extracoporeal membranous oxygenation was performed to treat this. Afterwards, the cardiogenic shock still persisted, and the auscultatory and echocardiographic findings revealed severe acute mitral valve regurgitation. Emergency mitral valve replacement was then performed. The ECMO and IABP were removed on the 2nd postoperative day. The patient was discharged on the 48th postoperative day.
