Anatomic correction of transposition of the great arteries.

ABSTRACT

Complete anatomic correction of transposition of the great arteries (TGA) and ventricular septal defect (VSD) was performed on 2 infants with high pulmonary arterial resistance. Both patients were operated upon under deep surface-induced hypothermia and limited cardiopulmonary bypass. Direct repair of the anomaly was accomplished by switching the aorta and the pulmonary artery with reattachment of the coronary arteries. The clinical result in the first patient was satisfactory. The postoperative cardiac catheterization and angiogram demonstrated no gradient across either outflow tracts and normal arrangement of the great vessels. The second patient died in the operating room, probably owing to compression or kinking of the left coronary artery.
