Postoperative evaluation of patients with tetralogy of Fallot repaired in infancy. Including criteria for use of outflow patching and radiologic assessment of pulmonary regurgitation.


The late hemodynamic and radiologic findings were good or excellent in 96 percent of 23 infants in whom tetralogy of Fallot was repaired with the use of profound hypothermia. These results encourage continuation of the policy of early repair rather than palliation in tetralogy of Fallot. The preoperative cineangiocardiographic assessment of the type and severity of the pulmonary stenosis accurately predicted the findings at operation and the type of repair required. In infants between 1 and 21 months of age and 3 and 10 kilograms in weight, a main pulmonary artery (MPA) diameter of less than 7 mm. was the cineangiocardiographic measurement most accurately predicting the necessity for an outflow patch across the pulmonary ring. Postoperative studies showed significant increases in the MPA and pulmonary ring diameters. A Method of cineangiocardiographic assessment of pulmonary incompetence is presented. Severe mechanical pulmonary incompetence in some patients produced mild hemodynamic effects by radiologic criteria.
