Abstract: Objective To further investigate the accuracy of the real-time three-dimensional echocardiography(RT-3DE) in evaluating right ventricular(RV) systolic function.Methods RT-3DE,MRI and SPECT were used to study a total 30 patients including 10 with coronary artery disease,7 with hypertension,5 with cardiomyopathy,5 with atrial septal defect,and 3 with pulmonary hypertension.The RV end-diastolic volume(RVEDV),RV end-systolic volume(RVESV),RV stroke volume(RVSV) and RV ejection fraction(RVEF) were measured.The correlation and the difference between different modalities were compared.Results RT-3DE had a good correlation with MRI in RVEDV,RVESV,RVSV and RVEF (rEDV =0.811,rESV =0.837,rSV =0.818,and rEF =0.701).Also RT-3DE had a correlation with SPECT in RVEDV,RVESV,and RVSV(rEDV =0.526,rESV =0.493,rSV =0.514),but there was no correlation between RT-3DE and SPECT in RVEF (rEF =0.235).Conclusions RT-3DE can assess RV systolic function accurately.
