[Perioperative myocardial infarction due to graft atheroembolism during coronary artery bypass surgery].
We presented a female patient who had complicated perioperative myocardial infarction resulting from intraoperative embolization with atheromatous debris during coronary artery bypass surgery. On separation from cardiopulmonary bypass, ventricular function was poor and she suffered from severe low cardiac output syndrome postoperatively. The intraoperative electrocardiographic monitoring showed conduction abnormalities, elevation of the ST-T segments and new Q waves. Though it is difficult to diagnosis the onset of perioperative myocardial infarction early, adequate treatment is necessary to preserve ischemic myocardium and to reduce the size of myocardial necrosis.
