title: Off-pump coronary artery bypass grafting for a patient with anomalous origin of the right coronary artery from the pulmonary artery.
abstract: We report on a case of a 70-year-old chronic hemodialysis patient. He presented with anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) and severe left anterior descending coronary artery (LAD) stenosis, which supplied collateral flow to the right coronary artery (RCA). The patient complained of myocardial ischemic symptoms during routine hemodialysis. We performed off-pump coronary artery bypass grafting (OPCABG) surgery and ligation of the origin of the ARCAPA. Previous reports described that the myocardial ischemia was a rare complication with the ARCAPA patients. However, this case required coronary revascularization because of the atherosclerotic LAD stenosis as a collateral source of the RCA.
