OBJECTIVE: To analysis of morbidity and mortality of surgical treatment of the classic of tetralogy of Fallot in the first year of life and particularly to define possible advantages of early primary repair. MATERIAL AND METHODS: Between March 1986 and September 1999, 56 children under one age tetralogy of Fallot underwent surgical treatment. Thirty-six (64.3%) were male and 20 (35.7%) female, ranging in age from 1 to 11 months (mean 6.5 ± 2.9 mo.). Weight ranged from 3 to 10 kg (mean 6.3 ± 1.8 kg). The patients were divided into 2 groups: Group I, consisted of 26 children operated on between 1986 and 1996, submitted to a Blalock-Taussig shunt; Group II, comprised of 30 children operated on consecutively since 1996 and submitted to intracardiac repair. RESULTS: In Group I, there were 2 (7.6%) early and 1 (3.8%) late deaths. No postoperative com-plications were observed in the remaining children. In Group II, 2 (6.6%) early deaths and 1 (3.3%) non-cardiac late death of a have occurred. Only 2 children had non-significant postoperative complications and 16 presented signs of congestive heart failure. The mortality in both groups was not statistically significant. CONCLUSIONS: In the authors' experience, ideal management of children with classical Fallot's tetralogy in the first year of life consists of the intracardiac repair since it has the same surgical risk as palliation.
