Arterial switch operation in neonates with complex congenital heart defects.
The aim of the study was to analyze short-term results of the arterial switch operation in 29 neonates with simple transposition of the great arteries (group A) and 18 (group B) with complex heart defects: transposition with a ventricular septal defect (10), coarctation of the aorta (5), or Taussig-Bing anomaly (3). The operations were usually performed on the 7th day of life (2nd-30th day), after a Rashkind procedure when necessary. The mean weight was 3,530 +/- 780 g, body surface area was 0.219 +/- 0.032 m(2). Delayed sternal closure was necessary in 7 patients from group A (24%) and 8 from group B (44%) because of hemodynamic instability after weaning from extracorporeal circulation; these neonates had significantly lower body weights and smaller body surface areas. Perioperative mortality was 13.8% (4 patients) in group A and 27.8% (5 patients) in group B. Correction of complex transposition tends to be associated with a higher operative risk than simple transposition, but the difference was not significant.
