Describe about Congenital Cardiac Conditions Encountered in Adults ?

The entire population of adults with CHD is constituted by patients whose cardiac malformations have a natural history allows survival into adulthood and patients with CHD who have undergone corrective or palliative procedures in childhood. In India, the former constitutes the majority because specialized pediatric cardiac services are limited to very few centres.

Approximately 30 per cent of all newborns have critical CHD. These are congenital heart diseases that do not allow survival or correction beyond the first few years of life (the small fraction of these newborns that survival beyond the first few years usually have irreversible pulmonary vascular obstructive disease that precludes any operation). A large number of conditions including most complex congenital cardiac malformations come under this category. For some of these conditions there clearly is a spectrum of severity.
