Abstract：Objective To analyze the application value of real-time three-dimensional echocardiography (RT-3DE) to reviews of ejection fraction and right ventricular volume in patients with moderate-severe pulmonary arterial hypertension (PAH). Methods PAH patients received treatment were chosen from People’s Hospital of Inner Mongolia Autonomous Region and Affiliated Hospital of Inner Mongolia Medical University, from Sept. 2016 to Jan. 2018, and divided into moderate PAH group and severe PAH group (each n=50). At the same time the healthy controls (n=50) were chosen into control group. The indexes of right ventricular ejection fraction (RVEF), right ventricular end-diastolic volume (RVEDV), right ventricular stroke volume (RVSV) and right ventricular end-systolic volume (RVESV) were detected by using RT-3DE. The indexes of right ventricular fractional area change (RVFAC), tricuspid annulus peak systolic velocity (S’), tricuspid annulus plane systolic excursion (TAPSE), right ventricular index of myocardial performance (RIMP), right ventricular free wall thickness (RV-FW), right atrial left and right diameter (RA-D1), right ventricular basal diameter (RV-D) and right atrial upper and lower diameter (RA-D2) were detected by using conventional echocardiography. The correlation among pulmonary arterial systolic pressure (PASP) and all above indexes was analyzed. Results RC-FW, RA-D1 and RA-D2 in moderate PAH group and severe PAH group and RV-D in severe PAH group were higher than those in control group, and RA-D1, RA-D and RA-D2 were higher in severe PAH group than those in moderate PAH group (P<0.05). RVEF was lower in moderate PAH group and severe PAH group than those in control group, RVEDV and RVESV in moderate PAH group and severe PAH group and RVSV in severe PAH group were higher than those in control group, RVEF was lower and RVEDV and RVESV were higher in severe PAH group than those in moderate PAH group (P<0.05). RVFAC and TAPSE in moderate PAH group and severe PAH group and S’ in severe PAH group were lower, and RIMP was higher than those in control group, and RVFAC and TAPSE were lower in severe PAH group than those in moderate PAH group (P<0.05). Conclusion RT-3DE can accurately and objectively review the ejection fraction and right ventricular volume in patients with moderate-severe PAH, and provide a reference for clinical diagnosis and treatment.
