The aim of the study was to review the status of patients with D-transposition of the great arteries after arterial switch operation (ASO). Patients: the study included 166 patients (115M/51F), operated on between January 1993 - December 2003. Mean follow-up was 5.8 years. Results: early mortality was 6 % (10 pts). In 5 pts (4.1 %) supravalvar pulmonary stenosis with gradient > 40 mmHg occurred, 4 of them underwent a catheter balloon and/or surgical dilatation. 1 patient (0.8 %) had a surgical treatment of supravalvar aortic stenosis (gradient 55 mmHg). Aortic regurgitation occurred in 47.5 % of patients, mostly trivial or mild. In 6 patients was one thin or completely missing main coronary artery branch found, with sufficient collateral circulation. Conclusion: arterial switch operation (ASO) is at present the method of choice because of low mortality and low incidence of severe complications.
