Epidemiology
Overview
Knowledge of the epidemiology of congenital heart disease depended on:
- The development of pediatric cardiology as a discipline and specifically on the increasing attention to newborns and to small sick infants, who in earlier days may have died without recognition of their heart disease.
- The development of good population study methods to identify this young case population and to select appropriate controls.
- The availability of computing resources to deal with extensive data collections.
