[Surgery of tetralogy of Fallot in the first year of life (author's transl)]. / Chirurgie de la tétralogie de Fallot pendant la première année de la vie.

Despite the very good results published by B. Barrat Boyes and A. castaneda with early correction of Tetralogy of Fallot in the first year of life, the authors prefer palliative surgery for this group. They have operated upon 47 infants less than one year of age, 15 of them being less than 2 weeks of age. The overall mortality is 4%, the only two deaths being in the neonate group, which is usually a very small group in the published series with early correction. Since all the children with S.P. Shunt performed for Tetralogy of Fallot can wait 2 to 4 years before complete correction, and since the mortality of corrective surgery at 4 years of age is almost nil, the authors think that the two stages approach give as good results than one stage surgery, despite the possibility of neurological complications which may occur between operations. They argue that with early correction, surgeons are obliged to put more transannular patches which result in more pulmonary insufficiency cases, and that the mortality in this age group is still very high in some publications. They have also compared the percentage of low cardiac output syndrome after correction and found that children with a previous S-P shunt have smoother post-operative course. Finally they think that it is possible to obtain a global mortality around 7% for the 2 stages approach and that this kind of surgery is technically easier than early correction and must be very useful for the majority of cardiac centers interested in congenital heart disease.
