Abstract

A 27-year-old man with a history of Kawasaki disease presented with chest discomfort. A coronary angiography (CAG) showed coronary aneurysms at the proximal portion of the left anterior descending artery (LAD) without significant stenosis, and complete obstruction of the proximal right coronary artery. We performed off-pump coronary artery bypass grafting (OPCAB) from either side of the internal thoracic artery (ITA). Postoperative CAG revealed flow competition in the left ITA graft. However, 3 years after the surgery, the patient experienced complete occlusion of the diagonal branch, but the left ITA graft reopened the occlusion. Thus, we believe that even in the absence of significant stenosis associated with coronary aneurysms, arterial grafting may prevent fatal myocardial infarction.
