Repair of Anomalous Single Coronary Artery From the Pulmonary Artery (ASCAPA).

We describe the management of an infant presenting with severe heart failure at 6 weeks of age found to have an anomalous single coronary artery originating from the main pulmonary artery (MPA). This patient was transferred to our hospital and ultimately had their coronary artery translocated to the ascending aorta successfully. Preoperative severe left ventricular (LV) dysfunction and moderate/severe mitral regurgitation (MR) improved to normal function and mild-to-moderate MR 6 weeks postrepair. Three-dimensional CT reconstructions proved valuable and allowed for accurate preoperative planning leading to successful coronary transfer.
