Abstract              Background: Although once considered a rarity in the Indian subcontinent, the prevalence of rheumatic heart disease (RHD) is now recognized to be very high, particularly among children and young adults Aims and Objectives: To Study Various Demographic distribution among valvular lesions in the Patients with Rheumatic heart disease. Methodology: Present study was carried to study the clinical profile of Rheumatic fever (RF) and Rheumatic heart disease (RHD) in patients of all age groups. The study was approved by the ethics committee prior to commencement of data collection. This cohort study was conducted on all cases diagnosed as Rheumatic fever and Rheumatic Heart Disease. 196 cases fulfilling inclusion criteria Statistical analysis was performed using SPSS. Descriptive statistics (frequency, mean and SD) were used for data presentation T-test, Chi square, z test and ANOVA test were used to test significant difference in mean of variables between two groups and more than two groups respectively. A probability of less than 0.05 was considered statistically significant. Result: MS, AR and AS were found to be common in >30 years age group with 13/17, 04/04 and 08/09 patients respectively. Combined diseases were common in >30 years age and multivalvular diseases were common in ≤30 years age. However in our study, patients of MS, AR, AS and combined diseases were significantly found in >30 years age (p<0.05) and MS was significantly found in ≤30 years age (p<0.05) In our study, MR was found equally distributed among (19/38) males and (19/38)females, MS and AS were more common in females. (16/17 and 08/09 patients respectively) AR was found in 03(75%) males and 01(25%) females. Combined diseases were equally distributed among males (11/22) and females (11/22). Multivalvular diseases were found in 18/37 males and 19/37 females. However in our study MS and AS were significantly found in females (p<0.01) and AR was significantly found in males (p<0.01). All valvular diseases were more common in rural populations and were found to be significant (p<0.05). Conclusion: It can be concluded from our study that MS, AR and AS were found to be common in >30 years age MS and AS were more common in females, All valvular diseases were more common in rural populations and were found to be significant
