A new surgical approach to a patient with anomalous origin of left coronary artery from pulmonary artery: A case report.

Anomalous origin of the left main coronary artery from the main pulmonary artery is a very rarely seen congenital heart disease in children. Fatal ischemic and arrhythmic complications usually occur during early infancy, when pulmonary vascular resistance falls and left coronary artery flow decreases. Nearly 10% of patients reach childhood and adulthood, if extensive collateral coronary artery circulation develops. In this article, we report our end-to-end anastomosis technique of the left internal mammary artery to the left main coronary artery in a-10-year-old patient.
