We present patients of corrected transposition of the great arteries and associated cardiac abnormalities, insufficiencies of both atrioventricular valves, conduction disturbances, surgical procedures and outcomes of 28 cases admitted to Department of Pediatric Cardiology in the period of 1985-1991. The patients' age ranged 2 months to 20 years. All patients were studied by two-dimensional echocardiography and then cardiac catheterization and angiography were performed on 23 of them. Seven patients (25%) had Ebstein's anomaly and one patient had straddling of left sided atrioventricular valve and 13 patients had ventricular septal defect. Left atrioventricular valve regurgitation was identified in 12 patients (43%) and mild right atrioventricular valve regurgitation was diagnosed in 3 patients. Pulmonary hypertension was present in 9 patients. Complete atrioventricular block was observed in four patients at their first admission. 11 patients underwent surgical correction. Only one of them died ten days after the operation. One patient developed left-sided atrioventricular valve regurgitation postoperatively. Surgically induced complete heart block was seen in 5 patients who had undergone ventricular septal defect repair. Consequently, we stress that in the follow-up of patients with corrected transposition of the great arteries, right atrioventricular valve regurgitation as well as left sided atrioventricular valve regurgitation should be investigated and that in the postoperative period the development of incompetence of the left-sided atrioventricular valve should be considered as a possibility.
