[Re-coronary artery bypass grafting for anomalous origin of left coronary artery from pulmonary artery (Bland-White-Garland syndrome) after operation in infancy: a case of 18-year follow-up].

Anomalous origin of the left coronary artery from the pulmonary artery is a very rare congenital malformation. Re-coronary artery bypass grafting was performed in a 18-year-old man who had received coronary artery reconstruction with a homologous saphenous vein (from his mother) at 7-months old. After the first operation, clinical course was uneventful, but the patient became symptomatic because of effort angina at age 15. The electrocardiogram showed abnormal ST segments in Lead V2-5 and abnormal T waves in Lead V5-6. Coronary arteriography revealed that saphenous vein graft was occluded. The left internal thoracic artery (LITA) was anastomosed to the left anterior descending artery and a two coronary system was established. Postoperative angiography revealed that LITA was patent, and relief of angina was obtained.
