Many surgical procedures for the implantation of anomalous left coronary artery from pulmonary artery have been described. A dual coronary system offers most benefit and is most advantageous for the patient. Two autogenous flaps of the pulmonary trunk and ascending aorta, without mobilizing the coronary artery, were created for use in this procedure. This technique was successfully used in an 8 month-old patient with severe myocardial dysfunction and moderate mitral regurgitation. This procedure allows 2 coronary systems to be repaired for any anatomic change of the left coronary artery without the use of prosthetic material. There were no technical complications. During the postoperative course minimal inotropic support was used. The magnetic resonance study, 11 months postoperative, showed wood How of the left coronary artery and mild mitral regurgitation. The operative technique was simple and its execution easy. The follow-up in the intermediate and late period showed the growth of this endothelized tube.
