Anomalous origin of the left coronary artery from the pulmonary artery: repair by aortic reimplantation.
From 1980 to 1990, 12 patients (mean age 2.5 years, range 5 months to 9 years) with anomalous origin of the left coronary artery from the pulmonary artery were treated surgically. Five infants were operated upon in the first year of life because of persistent symptoms of congestive heart failure. In all cases, a two-coronary system was constructed by direct aortic reimplantation of the anomalous vessel with no deaths early or late over a follow-up period of up to 10 years. The technique of reimplantation was facilitated by transection of the main pulmonary artery. One patient with severe mitral regurgitation underwent, in addition, a mitral annuloplasty. A pulmonary valvotomy was performed in another patient with associated pulmonary stenosis. Three patients are receiving medication. The reimplanted anomalous left coronary artery was patent in each reevaluated patient (10/12). Left ventricular function improved considerably in all cases. Patients with symptoms should undergo repair soon after diagnosis. Direct aortic reimplantation should be technically feasible in even the smallest infant. Operative mortality is related to preoperative conditions and severity of ischemic damage of the myocardium.
