[Long-term results of arterial switch operation].
Surgical results and late outcome in 202 patients who had undergone arterial switch operation from 1984 to 1997 were investigated. Actuarial survival was 90.6% at 10 years and 90.0% at 20 years. Fifty-two patients (25.7%) underwent reoperation for pulmonary stenosis and 7 patients (3.5%) had aortic valve replacement. Freedom from re-intervention was 71.9% at 10 years and 60.4% at 20 years. Using xeno-pericardial patch for pulmonary reconstruction was strong predictor for postoperative pulmonary stenosis. Coronary ischemic event was rare but some patients showed electorocardiogram (ECG) change on exercise and hypoplastic left coronary artery. Cardiopulmonary function was almost normal in long term survivors.
