Abstract：Objective To explore the application value of real-time three-dimensional echocardiography and two-dimensional speckle tracking imaging technology in assessing right ventricular function in patients with cirrhosis.Methods 91 patients with clinically diagnosed cirrhosis were selected and divided into Group A,Group B and Group C according to the Child-Pugh score.Additionally,30 healthy subjects were selected as a control group.RT-3DE was used to assess right ventricular ejection fraction(RVEF),right ventricular end-diastolic volume(RVEDV),right ventricular end-systolic volume(RVESV)and right ventricu-lar stroke volume(RVSV).2D-STI was utilized to measure right ventricular four-chamber longitudinal strain(RV4CSL)and right ventricular free-wall longitudinal strain(RVFWSL).Results Compared with the control group,Group A and Group B,RVEDV and RVESV of Group C increased,while RVEF,RVFWSL and RV4CSL decreased(P<0.05).In comparison with the control group and Group A,Group B showed the increased RVEDV and RVESV,and decreased RVEF and RVFWSL(P<0.05).Relative to the control group,Group A demonstrated increased RVESV,and decreased RVEF,RVFWSL and RV4CSL(P<0.05).Correlation analysis showed that RVEDV,RVESV were positively correlated with liver function grade,while RVEF,RVFWSL and RV4CSL were negatively correlated.Conclusion RT-3DE and 2D-STI offer quantitative assessment capabilities for evaluating functional alterations in the right ventricle of patients afflicted with cirrhosis,thereby presenting significant clini-cal significance.
