Abstract:
A neonate presented with d-transposition of the great arteries, aortic arch hypoplasia, aortic coarctation, and multiple ventricular septal defects. During the arterial switch procedure and the aortic arch repair, a fenestrated Gore-Tex disk (W.L. Gore & Assoc, Flagstaff, AZ) was sewn into the right ventricular outflow tract to restrict pulmonary blood flow. The internal right ventricular band successfully controlled the pulmonary blood flow, maintaining a systemic oxygen saturation of 88% to 92%, and allowing growth from 3.5 to 10.5 kg. At 8 months of age, the internal band in the patient was removed, and the ventricular septal defects were successfully closed.
