Anomalous left coronary artery, ventricular septal defect, and double aortic arch.

Anomalous origin of the left coronary artery from the pulmonary artery generally occurs in isolation. We report an infant diagnosed with double aortic arch and ventricular septal defect who was found to have an anomalous origin of the left coronary artery from the pulmonary artery at surgery. Successful ventricular septal defect repair, division of the arch, and aortic reimplantation of the left coronary artery was performed.
