[A successful management of acute myocardial infarction with severe left main trunk lesion using beating heart coronary artery bypass grafting: report of a case].

A 56-year-old male was admitted for sudden onset of severe chest pain and diagnosed as acute myocardial infarction (AMI). Emergency coronary angiography revealed complete obstruction of the left anterior descending artery (LAD) and 99% stenosis of left circumflex coronary artery (LCX), which was almost same with obstruction of the left main trunk coronary artery. Emergency coronary artery bypass grafting (CABG) to LAD and LCX was performed under a beating-heart. Left ventricular wall motion was improved after bypass grafting. CABG under a beating-heart is a new strategy for critical cases such as acute coronary syndrome. The better patency rate and the more complete revascularization that may be achieved with the new generation of stabilizers and retractors may improve long-term results.
