OBJECTIVE: Pediatric coronary artery bypass grafting is uncommon. Small target vessels and appropriate conduit choice are the main technical challenges. METHODS: Fourteen patients undergoing coronary artery bypass grafting from January 1986 to December 2008 were retrospectively reviewed. RESULTS: Median age was 10 years (range, 3-15 years); median weight was 36 kg (range, 12-71 kg). Indications included symptoms or evidence of inducible ischemia and angiographically documented coronary stenosis. Diagnoses included Kawasaki disease (5/14), anomalous left coronary artery originating from the pulmonary artery (2/14), previous stent implant (1/14), and metabolic disease (3/14). The remaining 3 patients had coronary stenosis after other cardiac operations. Preoperatively 5 patients (45%) had no symptoms and 9 (64%) had positive stress test. Single-vessel disease was demonstrated in 2 (14%), double-vessel disease in 7 (50%), triple-vessel disease in 1 (7%), and left main coronary artery involvement in 4 (29%). With standard cardiopulmonary bypass, 18 (81%) in situ internal thoracic arteries and 4 (19%) long saphenous veins were grafted. There was 1 early reoperation for graft failure. All patients survived to hospital discharge. Follow-up angiography was performed in 5 patients (36%; median, 2 years; range, 1 day-10 years), and 1 (7%) required late balloon dilatation. Median follow-up was 3.3 years (1 month-10 years), and 12 patients had no symptoms. There was 1 late death of noncardiac cause. CONCLUSIONS: Pediatric coronary artery bypass grafting can be performed for a wide range of indications. Midterm results are excellent. Preoperative stress testing can detect silent myocardial ischemia. 2010 The American Association for Thoracic Surgery. Published by Mosby, Inc. All rights reserved.
