Anomalous left coronary artery from the pulmonary artery: creating an autogenous arterial conduit for aortic implantation.

Anomalous origin of the left coronary artery from the pulmonary artery requires surgical correction. A surgical technique is presented. Two infants underwent re-implantation of their anomalous left coronary arteries by creating a tunnel using autogenous aortic and pulmonary arterial walls. The advantage of this technique is that the new left coronary artery lies in the horizontal plane and in an anatomically correct axis running in the groove behind the pulmonary artery. It also provides a tension free endothelialized autogenous arterial walls with normal growth anticipated.
