Background: Prevalence studies on Congenital heart Diseases (CHDs) have been done several times world wide and such studies are very limited in Indian populations. A few earlier studies in India have reported an increased prevalence of CHDs ranging from 2.25 to 50.89 per 1000 live births. Aims and Objective: To study the prevalence of congenital heart diseases in Indian population. Materials and Methods: Data on the prevalence of CHDs were collected and analyzed from the three major hospitals of Mysore, Cheluvamba Hospital, CSI Holdsworth Memorial Hospital and J.S.S Hospital from the year 2000 to 2004. Results: The prevalence of CHDs for five years in Mysore hospitals ranges from 6.6 to 13.06 per 1000 live births. The most frequent type of CHD was found to be VSD (40.47%) followed by ASD (19.06%), TOF (13.38%) and PDA (9.53%). It is clear that the maximum CHDs were detected in the first year of life when compared to the later years of life. The prevalence of CHDs in Mysore is increasing from 2000 to 2004 which might be due to the improvement of diagnosis, attention or awareness among the medical authorities on the disease. Conclusion: The prevalence of CHDs in Mysore is not very high as reported in other parts of the country, however; it is an important disease which needs an immediate medical attention.
