Background: In Rheumatic heart disease, mitral valve is most commonly affected. Approximately 25% of all patients with rheumatic heart disease have pure mitral stenosis. 10% of all rheumatic heart disease patients have pure mitral regurgitation and 40% have combined mitral stenosis and mitral regurgitation. This study is the correlation between clinical status and common pulmonary functions in patient with mitral valvular disease and improvement in pulmonary functions after surgery in mitral valvular heart diseases. Aim and objectives: To study the pulmonary function test (PFT) in patients with mitral valvular heart diseases, to study PFT in patients with mitral valvular heart diseases with various age groups, to study clinical features and investigatory profile of mitral valvular heart disease patients, to study PFT in various stages of mitral stenosis and mitral regurgitation, to compare the pulmonary function test results before and after treatment of mitral stenosis (MS) and mitral regurgitation (MR). Material and methods: This present study was carried out of total fifty patients of mitral valve disease to determine the changes in Spirometric pulmonary function. Out of this, forty patients were of mitral stenosis and ten patients were of mitral regurgitation. These patients were selected from indoor as well as outdoor cases of Civil Hospital, Ahmedabad and U. N. Mehta Cardiology Institute, Ahmedabad. The diagnosis was made by clinical features, X-ray, electrocardiography and echocardiography studies and all Patients, selected for study, were underwent operative procedure. Results: Mean age of cases in this study was 30.46 years. So that present study showed that younger age groups were more affected in rheumatic mitral stenosis and regurgitation. Present study showed that mean value of FEV1/FVC% was 84.69 % in NYHA class II, 88.49% in NYHA class III and 81.51% in NYHA class. Present study showed that mean value of FEV1/FVC% of all classes were 86.06% preoperatively and after operation 89.94%. Present study showed that mean value of FEF 25-75% was 2.47 liter/sec preoperatively and after operation 2.81 liter/sec. Conclusion: In all cases of mitral valve disease, pulmonary function tests abnormality predominantly reveals restrictive pattern of lungs.
