[Emergency off-pump coronary artery bypass grafting for a nonagenarian with acute myocardial infarction; report of a case].

: A 92-year-old man was presented with chest pain in home clinic. And he was transferred to our hospital for emergent operation of the acute myocardial infarction. Emergent coronary angiography (CAG) revealed the occlusion of left main trunk (LMT) and 2 vessels disorder. The patent was indicated of an emergency off-pump cardiac artery bypass graft (OPCAB). Our patient had a favorable post-operative course without severe complications, and discharged on post-operative day 23. It is difficult to standarlize the cardiac operation technique and indication of advanced elderly patients. In spite of lower safety margin of nonagenarians, we have to reevaluate the indication considering with physical defect, post-operative quality of life (QOL), the will of patients and their families themselves.
