Anomalous origin of the left coronary artery from the pulmonary artery. New operative technique.

Abstract

We report a new operative technique for repair of anomalous origin of the left coronary artery from the pulmonary artery. The principles of the proposed technique are left main coronary angioplasty using a transected main pulmonary artery, side-to-side anastomosis of the aorta and newly created left coronary artery, and direct anastomosis of the transected pulmonary artery. No prosthetic material is used in this procedure. Our experience in two adults (a 35-year-old man and a 68-year-old woman) indicated that this technique permits two coronary system repair for any anatomic variation of the left coronary artery without the use of prosthetic material. This is more advantageous in infants.
