Correlation of Pulmonary Hypertension and Severity of Mitral Stenosis

Abstract

aim of study: The aim of study is to define the correlation between mitral valve stenosis and its predictors of severity as pulmonary hypertension and other cardiac valves lesions. Material and Methods: This study that enrolled total 80 patients, 25 males and 55 females and their age range from 15 to 60 years old , with male to female ratio 1:2.2 . The study was conducted in Al sadder teaching hospital in Al Najaf governorate during the period from May 2012 to May 2013. Echocardiography was done for all patients to assess mitral valve area by planimetry, detect other valves lesion and assess right ventricular systolic pressure which is equal to pulmonary artery systolic pressure (PASP) . Results & Discussion: This study shows that the increased incidence of moderate to severe mitral stenosis in female as compared with male and there were no statistically significant difference between age groups. There was statistically significant correlation between severities of mitral valve stenosis with increased systolic pressure of pulmonary artery since the more severe mitral stenosis, as the higher pulmonary hypertension. There were no statistically significant correlation between mitral stenosis severity and other cardiac valves. There were statistically significant correlations between pulmonary hypertension and tricuspid regurgitation with or without mitral regurgitation. There were increased incidence of moderate to severe mitral stenosis in female as compared with male and there were no statistically significant difference between age groups. There were statistically significant correlation between severity of mitral valve stenosis with increased systolic pressure of pulmonary artery since the more severe mitral stenosis. There were statistically significant correlations between pulmonary hypertension and tricuspid regurgitation .Conclusions: The predictors for mitral stenosis severity in this study that female, younger than 40 years old, echocardiographic evidence of pulmonary hypertension and tricuspid regurgitation with or without mitral regurgitation. Recommendation: We recommended that follow up all patients with mitral valve stenosis by pulmonary artery systolic pressure measured by echocardiography.
