Abstract:
23 patients (10 males, 13 females) with mitral stenosis aged from 23-50 years of old (mean 37.5 years) were enrolled in the study. Valvular opening area ranged from 0.7cm2 to 1.2cm2. 5 patients have mitral stenosis alone. 18 patients have mitral stenosis with insufficiency grade I, II. 14 patients have sinus rhythm and 98 patients have atrial fibrillation. Pulmonary artery pressure ranged 25mmHg to 45mmHg when measuring directly. There was closed positive correlation between pulmonary artery pressure and right ventricular pressure with r= 0.509 for pre-operation and 0.548 for post-operation. After valve detachment, both pulmonary artery pressure and right ventricular pressure decreased rapidly and dramatically in comparison with prior detachment with p = 0.01.
