In transposition of the great arteries without intact ventricular septum, the ventricular configuration is one factor limiting total intracardiac repair. In six patients with uncorrectable ventricular configuration and pulmonic stenosis, a superior vena cava-pulmonary artery anastomosis was done without mortality. Pulmonary vascular disease, another limiting factor, was found in four patients who failed to survive an intraventricular repair combined with a Mustard atrial septoplasty. There was one survivor. Two 8-year-old children who had pulmonary artery banding in infancy survived total intracardiac repair combined with removal of the band. The data and experience lead to the opinion that an optimal pulmonary artery banding in infancy followed by a total repair in the latter part of the first decade warrants an adequate clinical trial.
