Congenital heart disease is one of the most frequent malformations in newborn children with a prevalence of about 1%. Of these children, about 28% need diagnostic heart catheterization followed by cardiac surgery or catheter intervention in about 31% of cases. Although there are ongoing programs to establish local centers in developing countries, 93% of patients still require transfer to specialized centers in developed countries to undergo surgery. This results in a significant number of newborns and children suffering from congenital heart disease who need international interhospital transfer.
