A 45-year-old woman was admitted to our hospital because of chest pain on exertion. She was diagnosed to have an anomalous aortic origin of the right coronary artery (RCA) arising from the left sinus of Valsalva, passing between the aorta and the main pulmonary artery. Exercise treadmill test demonstrated significant depression of ST segments in leadsⅡ,Ⅲ and aVF.Because medical treatment was ineffective, reimplantation of the RCA was performed. Dysfunction of the reimplanted RCA occurred, however 3 hours after surgery, and emergency coronary artery bypass grafting was performed using a saphenous vein graft to the RCA. After the 2nd operation, postoperative course was uneventful and multidetector row computed tomographic angiography revealed the patent vein graft and narrowing of the relocated site of RCA.
