Successful anatomic correction of transposition of the great vessels. A preliminary report.

TLDR

The authors introduce a novel surgical technique for anatomically correcting transposition of the great vessels. The procedure involves transposing the coronary arteries with a segment of aortic wall, patching the aortic openings, transecting and reanastomosing the aorta and pulmonary artery, and closing the interventricular septal defect via a right ventriculotomy with a dacron patch. In a 40‑day‑old infant, the operation under deep hypothermia and total circulatory arrest resulted in an uneventful recovery, with hemodynamic assessment at 20 days confirming complete correction and the patient weighing 5,500 g without cyanosis at 50 days.

Abstract

The authors present a new approach for anatomical correction of transposition of the great vessels. The two coronaries with a piece of aortic wall are transposed to the posterior artery. The two aortic openings are closed with a patch. The aorta and pulmonary artery are transected, contraposed and then anastomosed. The interventricular septal defect was closed through a right ventriculotomy with a dacron patch. A 40-dayold white male infant with 3,700 g was operated on with deep hypothermia and total circulatory arrest and made an uneventful recovery. The hemodynamic study 20 days after surgery showed the complete correction of the malformation. At 50 days after surgery, he weighed 5,500 g, without cyanosis and in good conditions.
