Pediatric cardiovascular surgery in South america: current status and regional differences

Abstract

Very little information is available about the epidemiology of congenital heart disease in developing parts of the world, including South America. This article describes the incidence of congenital cardiac disease, the different treatment rates among countries, and future solutions for achieving improved coverage for the children with cardiac diseases in South America. An incidence of congenital cardiac disease of 8 per 1000 live births appears to be a fair approximation for the population of the world and also the population in South America. Nevertheless, a wide variation exists in the observed incidence of congenital cardiac disease in South American countries, which can be partly explained by inequalities in the access to diagnosis, differences in the diagnostic criteria, and true regional variations. It is estimated that 58,718 children are born yearly with congenital heart disease in South America. Brazil, Colombia, and Argentina have the highest number, followed by Peru, Venezuela, Chile, Ecuador, Bolivia, Paraguay, Uruguay, and Guyana. It is also estimated that in South America, 24,081 children per year with a new diagnosis of congenital cardiac disease do not receive any treatment. This paper provides strategies for improving the access to and quality of pediatric cardiac surgery in South America.
