Advantage of vein grafts for anomalous origin of a right coronary artery.
A 66-year-old man with anomalous origin of the right coronary artery suffered from chest pain. The results of coronary angiography and multidetector computer tomography indicated that the proximal right coronary artery was intermittently compressed, causing the ischemia. Coronary artery bypass grafting was regarded as a reliable treatment compared with percutaneous coronary intervention or other surgeries. Because of plentiful flow of the right coronary artery, we decided to use a vein graft to avoid competitive flow. Postoperative coronary angiography revealed intact flow in both the native coronary artery and the vein graft 1 year after the surgery. The myocardial ischemia seen on scintigraphy and the chest pain had disappeared.
