Abstract
Eighty-one patients with tetralogy of Fallot malformations evaluated between July 1, 1971 and November, 1975 are presented. Fifty-one patients underwent primary intracardiac repair; three died. Twenty-seven patients were corrected after a previous palliative shunt; there was one death. Three additional patients have been palliated and are awaiting repair. While the overall mortality in these patients was less than 5%, the infants undergoing total correction before the age of two years appeared to be at greater risk (25%). There were no deaths in the group of patients undergoing palliative procedures. Based on these data it appears that a safely performed palliative shunt in the symptomatic small infant is a reasonable first step, particularly if the outflow tract of the right ventricle is diffusely hypoplastic.
