Anomalous aortic origin of the left coronary artery (AAOLCA) is a rare occurrence. This anomaly may lead to myocardial ischemia and, therefore, surgical repair is recommended to improve long-term survival in these patients. We present a case of successful mobilization of an anomalous left main coronary artery, pulmonary artery translocation, and interposition graft to the right pulmonary artery with a late complication of right pulmonary artery graft occlusion. This case illustrates the difficulty in the recanalization of pulmonary artery graft occlusion and stenosis, and highlights the utility of treatment via a staged approach.
