[Stanford Type A Acute Aortic Dissection with Acute Myocardial Infarction due to Compression of Left Main Coronary Artery:Report of a Case].

A 58-year-old man was admitted to our institution with sudden onset of hypotension and acute ischemia of left lower extremity. Electrocardiography showed ST segment elevation in leads V1~V6 and a transthoracic echocardiogram revealed antero-septal wall hypokinesis. He was given a diagnosis of acute myocardial infarction caused by left main coronary artery compression due to acute aortic dissection by enhanced computed tomography. We implanted a stent in the left main coronary artery and performed right external iliac-left femoral arterial bypass under general anesthesia. We performed a conventional total arch replacement and frozen elephant trunk and mitral valve repair at day 16. His postoperative course was good. Implantation of a left main trunk stent is an effective strategy for Stanford type A acute aortic dissection with left main coronary arterial occlusion before surgical repair.
