Anomalous origin of the left coronary artery from the pulmonary trunk: its clinical spectrum and current surgical management.
An anomalous left coronary artery arising from the pulmonary artery is a rare congenital anomaly which carries a serious prognosis with a high mortality in infants. Our experience in the surgical treatment of 9 patients with this condition during the last 5 years is discussed. The majority of patients were under the age of 2 years and presented with left ventricular failure. Surgical procedures included simple ligation of the left coronary artery, left subclavian to left coronary artery anastomosis, interposition vein graft, and direct reimplantation of the left coronary artery into the aorta. Patients treated by simple ligation survived the procedure but did not show improvement. Results with the subclavian artery to left coronary artery anastomosis were disappointing. Direct reimplantation or interposition of a saphenous vein graft appears to be the method of choice.
