Abstract
Forty-one consecutive patients, ranging in age from 41/2 to 27 years, were operated upon for complete repair of tetralogy of Fallot without an operative mortality. Postoperative catheterization of 25 patients permitted objective evaluation of the results which were, by the criteria adopted, excellent in 16 patients, good in 5, and poor in 4, including the 2 late deaths. Surgical experience has shown the necessity for extensive resection of the right ventricular outflow tract. Prosthetic patches are considered necessary for closure of most of the ventricular septal defects encountered, but are infrequently needed for reconstruction of the right ventricular outflow tract. Its use is indicated in certain patients with hypoplasia of the pulmonary annulus or artery. Age has been an important factor in patient selection. It is suggested that symptomatic patients under five years of age may benefit from a systemic-to-pulmonary arterial anastomosis before definitive correction is undertaken later in childhood.
