Revascularization of Chronic Occlusive Disease of a Right Pulmonary Artery Graft

Abstract

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 the 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.
