Because they were in profound shock, 2 patients required mechanical support with extracorporeal membrane oxygenation before the operation. Another patient was given moderate inotropic support and treated with an intraaortic balloon pump before surgery, because he had a dominant right coronary artery with extensive collateral circulation to the left coronary artery. All 3 patients underwent surgical revascularization within 20 hours of acute occlusion. Two patients survived, although I of them required extracorporeal membrane oxygenation support for 5 days postoperatively. The 3rd patient, despite successful weaning from extracorporeal membrane oxygenation immediately after coronary revascularization, died of hypoxic encephalopathy due to prolonged preoperative resuscitation. Immediate surgical revascularization was an effective treatment in our 3 patients who were in cardiogenic shock due to acute total occlusion of the left main coronary artery. Such factors as abundant collateral vessels from the right coronary artery to the left coronary artery, complete surgical revascularization within 20 hours of acute occlusion, and mechanical circulatory support were deemed important to recovery of left ventricular function. Two of our 3 patients survived.[SDGs]SDG3inotropic agent; adult; aorta balloon; article; brain disease; cardiogenic shock; case report; cause of death; coronary artery dilatation; disease course; electrocardiography; extracorporeal oxygenation; heart infarction; heart left ventricle function; heart muscle revascularization; human; left coronary artery; male; resuscitation; survival; Adult; Coronary Artery Bypass; Coronary Vessels; Extracorporeal Membrane Oxygenation; Humans; Intra-Aortic Balloon Pumping; Male; Middle Aged; Myocardial Infarction; Shock, Cardiogenicjournal article110934182-s2.0-0033770899
