Immediate effect of Mitral Balloon Valvotomy on Pulmonary Hypertension and LV. Volume, and Systolic Function in Severe Mitral Stenosis

Abstract

Cm immediately after and to 1.83 ± 0.15 Cm' 3 month after the procedure . The PASP decreased from 52.05 ± 16.16mmHg to 36.95 ± 12.8mmHg immediately after and to 31.2 ± 12 mmHg 3 months after the procedure. Fifteen patients (75%) showed decreese of PASP to near • normal and 5 patients (25%) showed persistently elevated PASP. Patients who showed persistently elvated PASP were more likely older in age, with higher echoscores, smaller mitral valve area and higher PASP before the procedure. Global left ventricular fuction (EF%) were improved from 56.8 ± 6.1 to 62.2 ± 5.1 and this was due to increased left ventricular enddiastolic dimentions from 49.65 ± 2.8 (0 52.6 ± 2.4 The pulmonary artery pressure and left ventricle dimension & EF were studied in 20 patients with severe MS before , immediatily after and 3 months after successful PBMV by Echo• Doppler to evaluate the effects of optimal valvotomy on these parameters. Results of this study were shown 111 tables 5 to 16 and summerised as the following : The MVA increased from 1.03 ± 0.14 Cm • to 1.93 ± 0.13 The PASP decreased from 52.05 ± 16.16mmHg to 36.95 ± 12.8mmHg immediately after and to 31.2 ± 12 mmHg 3 months after the procedure. Fifteen patients (75%) showed decreese of PASP to near • normal and 5 patients (25%) showed persistently elevated PASP. Patients who showed persistently elvated PASP were more likely older in age, with higher echoscores, smaller mitral valve area and higher PASP before the procedure. Global left ventricular fuction (EF%) were improved from 56.8 ± 6.1 to 62.2 ± 5.1 and this was due to increased left ventricular enddiastolic dimentions from 49.65 ± 2.8 (0 52.6 ± 2.4
