Surgery for congenital heart disease.

General agreement has been reached on the indications for treating most congenital cardiac malformations. Strong disagreement exists, however, about timing and methods of treatment, either for congenital heart defects, for which the approach should be standardized after years of use, and even more when a new technique or a new approach is introduced to replace the existing ones. The ideal solution should be to perform prospective, randomized studies, with long-term follow-up, possibly with preliminary experimental studies to support the hypothesis. Unfortunately this is rarely possible, either because of the nonreproducibility of the malformation in an experimental environment, or because prospective, randomized studies with adequate follow-up are rarely feasible, due to the relatively small number of children with the same congenital heart defect. An updated review of the current trends in congenital heart surgery, based on the papers published in the past year, is presented here.
