Early results for anatomic correction of transposition of the great arteries and for double-outlet right ventricle with subpulmonary ventricular septal defect.
Fifty patients, 21 with transposition of the great arteries plus ventricular septal defect, four with double-outlet right ventricle plus ventricular septal defect, and 25 with transposition of the great arteries plus intact ventricular septum, have undergone anatomic correction. There were four hospital deaths, all in the patients with ventricular septal defects (overall mortality rate 8%). The Lecompte maneuver was used in all patients, and in the last 25 patients the coronary arteries were transposed to medially hinged trapdoor flaps created in the neoaorta. In 10 patients (20%) intraoperative adjustments were necessary to the great vessels and coronary arteries to achieve unobstructed coronary artery flow. There have been no late deaths. Postoperative cardiac catheterization in 19 patients has revealed stenosis on the new main pulmonary artery suture line to be the main early problem. Anatomic correction of transposition (with or without ventricular septal defect) and double-outlet right ventricle septal defect would seem to be a good operative alternative to the Mustard or Senning operation, with the advantage of incorporating the left ventricle into the systemic circulation.
