India has a population of 1.2 Billion, second to China. Diagnosis and treatment for congenital heart disease has become prevalent only during the last 20 years. In this presentation, we report our experience with a series of 711 patients above the age of 18 years with congenital heart disease seen in a single institution between 2004 and 2008. We have reported earlier, a series of 1142 adults with congenital heart disease at the international society of Adult congenital heart disease meeting held in 1998 at Houston. The above series has not been quoted in this paper at all since the Institution has changed and the follow up has not been sufficient .Both the earlier and the present series are a single surgeon’s experience from two institutions. There are other institutions in Chennai performing congenital heart surgery. The combined experience of all the institution in Chennai will be more extensive. In the present study, Patients are assessed using a questionnaire to obtain information on their Present age, Education, Employment status, marital status, if married, how many children, whether children are healthy / having congenital malformations, whether on continued medical treatment, Quality of life, frequency of follow-up, current financial status including whether independent or in service.
