Isovolumic phase indices of right ventricular(RV) systolic function were evaluated in 9 normal control cases(Group I) and 9 patients with mitral stenosis(Group IIa) and 8 patients with mitral stenosis and aortic regurgitation(Group IIb). RV systolic pressures of all patients in Group II(n=17) were over 40mmHg RV dp/dt max, Vmax and Vpm were measured by digitizing method and V(CE10) were measured by manual tangent method. RV isovolumic contractile functional indices were greater in Group II(n=17) compared with those in Group I(n=9) : RV dp/dt max(mmHg. Sec(-1)) 347.8+/-104.4(mean+/-SD) VS 230.5+/-65.5(p<0.05), Vmax(Sec(-1)) 30.9+/-10 VS 20.1+/-5.18(p<0.05), Vpm(Sec(-1)) 22.96+/-9.63 VS 14.8+/-4.04(p<0.05) and V(CE10)(Sec(-1)) 20.4+/-7.11 VS 12.5+/-5.31(p<0.05). But no significant differences were noted between Group IIa(n=9) and Group IIb(n=8) in these indices. In all cases(n=26), significant correlations were noted between V(CE10) and Vmax(r=0.90), V(CE10) and Vpm(r=0.85). We summurized that RV contractile function is preserved in many cases with mitral stenosis and V(CE10) may be used as an convenient index for RV contractile function.

4.Rheumatoid mitral stenosid - comparison of echocardiographic mitral lesion and close cardiac valvotomy
Journal of Practical Medicine 2000;383(6):5-12
A study was carried out on the extent of echocardiographic mitral lesion and results of close cardiac valvotomy in 43 patients with rheumatoid mitral stenosid (male: 12) in Viet Duc during 1997-1998. The results showed that: the extent of echocardiographic mitral lesion as scores of Wilkins played a role in the prognosis of close cardiac valvotomy. The high scores usually indicated for poor prognosis. The close cardiac valvotomy found good outcome, stable post operation in almost of patients.

In our study we estimated mitral orifice area by use of two dimensional echocardiography in 59 patients with mitral stenosis form February 1979 till June 1981. We classified them to 3 subgroups by severity of mitral stenosis as Cope was done in 1975. and investigated correlationship between the severity and other various echo-cardiographic findings indices such as mitral valve calcification, posterior mitral leaflet motion, doming of mitral valve, EF slope, ED amplitude, LA dimension, LA/Ao ratio and especially mitral valve closure index. The following results were obtained. 1) We could accurately estimate mitral orifice area by two dimensional echocardiography. 2) Except EF slope and MVCI, we could find that various echocardiographic findings were poorly correlated with mitral orifice area measured from two-dimensional echocardiography. 3) MVCI was overlapped less frequently than EF slope in severe, moderate and mild mitral stenosis, and we could find that MVCI reflected the extent of mitral stenosis more accurately than EF slope.

To evaluate the change in valvular morphology and occurence and severity of mitral regurgitation produced by PMV, 45 patients(33 women and 12 men,mean age 38+/-10 years) were studied using two-dimensional(2-D) and Doppler echocaediography before and 1-2 days after this procedure. Mitral valve area after PMV increased in all patients, from 0.9+/-0.2 to 1.8+/-0.4cm2(P<0.0001). In valve area estimation, the correlation between Gorlin`s method and 2-Dechocardiography was better(r=0.61, p<0.0001) than that between Gorlin`s method and Doppler pressure halftime(r=0.38, P<0.01) before valvuloplasty, but after the procedure Gorlin`s and 2-D image valve area correlated less well(r=0.33, P<0.05) than Gorlin`s-Doppler pressure halftime correlation(r=0.46, P<0.002). Before PMV, 37 patients had no mitral regurgutation, 7 had grade 1 and 1 had grade 2 mitral regurgutation. After PMV, new mitral regurgutation occurred in 14 patients, increased in severity in 5 patients and so mitral regurgutation newly developed or increased in severity in 19(42%) patients. There were no differences between the patients with and those without an increase in mitral regurgutation after PMV, in age, sex, caediac rhythm, initial mitral valve area, increase in mitral valve area and fluoroscopic calcification. However, morphologic characteristics especially mobility(P<0.01) and thickening(P<0.05) of mitral leaflets were better pressured, and EBDA/BSA(effective balloon dilating area/body surface area) was significantly smaller(P<0.02) in patients without an increase in mitral regurgutation. Thus, an increase in mitral regurgutation after PMV might be related to the features of valve morphology especially and thickand EBDA/BSA.

10.Evaluation of the pulmonary artery and right ventricular pressures in the patients with mitral stenosis using directive measurement prior and after closed mitral detachment
Journal of Practical Medicine 2002;435(11):27-28
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.
