Background: Prosthetic heart valve replacement is the commonest choice in case of valvular failure or functional impairment. Although, they are considered to be ideal choices, they are vulnerable to dysfunction depending on various factors. Arising valvular dysfunctions are mostly related to stenosis or regurgitation. Methodology: This is a descriptive study including 30 participants out of which 17 are male and 13 are female. Subjects between 20 and 80 years of age with mitral valve replacement were included in the study with their consent. Subjects with other cardiac complications were excluded. The study was conducted for 12 months in the department of Echocardiography in a private institute for Cardiac sciences. Outcomes were assessed using ECG, ECHO, Catheterisation data, complications, type of valve used and symptoms associated with dysfunction. Results: Hypertension was seen in 50% subjects and mechanical valve was mostly used in subjects about 46.7%. observing the symptoms associated with dysfunction, syncopewas noted majorly in men about 93.3% and dyspnea was commonly seen in women about 63.3%. Dysfunction commonly occurred in 80% men on acitrom medication and 43.3% women on warfarin treatment. Conclusion: In conclusion we report that mechanical valves tend to cause valvular dysfunction alone or when supported by various other factors like use of drugs, comorbidities, social habits, and other cardiac disturbances. Although they are considered to be potentially a greater choice, they still tend to cause dysfunction which hinders the therapeutic progress. Further studies in larger sections need to be conducted to analyse the results more specifically and provide better therapeutic outcomes.
