Abstract：Objective To explore the correlation between ultrasound, right ventricular quantitative system and right heart catheterization in evaluating right ventricular systolic function in patients with pulmonary hypertension. Methods Twenty-two patients with pulmonary hypertension hospitalized in the First Affiliated Hospital of University of Science and Technology of China (Anhui Provincial Hospital) from August 2022 to May 2023 were enrolled in this retrospective analysis. These patients all accepted examinations of ultrasound, right heart quantitative system and right heart catheterization. The correlation between traditional ultrasound parameters, right ventricular quantitative system parameters and right heart catheterization parameters were analyzed, including lateral tricuspid annulus displacement (TAPSE), lateral tricuspid annulus velocity (TASPV) and right ventricular area change fraction (RVFAC), right ventricular ejection fraction (RVEF) and right ventricular cardiac output (RVCO) , cardiac output measured by thermodilution (TDCO). Results TAPSE was positively correlated with RVCO and RVEF (r=0.698, 0.678, P<0.01), TASPV was positively correlated with RVCO and RVEF (r=0.451, 0.507, P<0.05), RVFAC was significantly positively correlated with RVEF (r=0.971, P<0.01); TAPSE was positively correlated with TDCO (r=0.680, P<0.01). There was no correlation between TASPV, RVFAC and TDCO. RVCO was significantly positively correlated with TDCO (r=0.918, P<0.01). The Bland Altman scatter plot showed that the mean difference between RVCO and TDCO was-0.198 L/min (95％ CI:-1.29-0.89 L/min, P>0.05), indicating the high consistency between the two measurement methods. Conclusion Right ventricular quantitative system and right cardiac catheter have good correlation in evaluating right ventricular systolic function and there is no significant difference in measuring cardiac output between them. Right ventricular quantitative system can be used as a new non-invasive method for evaluating right ventricular function.
