Abstract：Objective To evaluate right ventricular(RV)volume and function in patients with rheumatic mitral stenosis(RMS)by real-time three-dimensional echocardiography(RT-3DE).Methods Forty-six patients of RMS with mild(n=16),moderate(n=13)and severe(n=17)stenosis were examined by RT-3DE.Sixteen age-matchod healthy adults in sinus rhythm with normal electrocardiogram and routine echocardiogram were enrolled as controls.The right ventricular end-diastolic volume(RVEDV)and right ventricular end-systolic volume (RVESV)were measured and the right ventricular ejection fraction(RVEF)was calculated.Results There was no significant differences of RVEDV between mild stenosis patients and healthy controls(P>0.05),but tllere were significant differences among patients with moderate(P<0.05)and severe(P<0.01)stenosis and healthy controls.RVESV of patients with mild or moderate(P<0.05)or severe(P<0.01)stenosis was significantly greater than that of controls.RVEF was significantly lowerin all the patients that in with healthy controls(P<0.01).Furthermore,RVEDV of patients with severe stenosis was significantly greater than that of mild stenosis(P<0.05).There was a significant difference of RVE Fbetween patients with mild and severe stenosis(P<0.01).Conclusions RV function is impaired earher than LV function in patients with RMS.Patients with modemte or severe stenosis have a higher RV volume and lower RV function than healthy persons.RT-3DE can accurately evaluate RV function.
