ANOMALOUS ORIGIN OF THE LEFT CORONARY-ARTERY FROM THE PULMONARY-ARTERY - NEW OPERATIVE TECHNIQUE

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 tran sected main pulmonary artery, side-to-side anastomosis of the aorta an d newly created left coronary artery, and direct anastomosis of the tr ansected pulmonary artery. No prosthetic material is used in this proc edure. Our experience in two adults (a 35-year-old man and a 68-year-o ld woman) indicated that this technique permits two coronary system re pair for any anatomic variation of the left coronary artery without th e use of prosthetic material. This is more advantageous in infants.
