Abstract
Objective: To determine the frequency of mitral valve prolapses in patients with mitral regurgitation in our population.
Methodology: This cross sectional study was conducted at the Cardiology Department of Hayatabad Medical Complex, Peshawar, Pakistan. A total of 121 cases of Mitral regurgitation were included through consecutive sampling technique.
Results: Out of 121 patients with mitral regurgitation, 20 had mitral regurgitation that was due to MVP. There were 55% females with mitral regurgitation. Mean age was 25.6±6.95 years (range 21 to 40 years). The different percentage of mitral regurgitation due to MVP among patients with mitral regurgitation was 16.52%, whereas 83.47% had rheumatic mitral regurgitation. 55% patients affected with mitral regurgitation due to MVP were between 21 to 30 years of age, predominantly affecting males in this age group (72.72%).
Conclusion: Mitral regurgitation due to MVP is less common in our population as compared to regurgation due to RHD and predominantly affects females.

Key words: Mitral regurgitation, mitral valve prolapse, valvular heart disease.
