Pulmonary Hypertension in Mitral Valve Disease-Rheumatic Mitral Stenosis versus Organic Mitral Regurgitation: The Doppler-Echocardiographic Study Revisited

Background: Pulmonary hypertension (PH) is common in patients with mitral valve disease. Objective: To determine the factors associated PH among disease, and similarities differences subgroups of stenosis (MS) regurgitation (MR). Materials Methods: Patients isolated moderate to severe organic disease were prospectively enrolled. was defined echocardiographically as pulmonary artery systolic pressure more than 50 mmHg. MS who had area 1.5 cm² MR effective regurgitant orifice less 20 mm² excluded. Results: Three hundred eighteen a mean age 54.3±15.5 years including 57.6% female 66.7% included this study. present 119 (37.4%), 48.1% 31.8% MR. Severe reported 245 (77.0%).
