The accuracy and influencing factors of Doppler echocardiography in estimating pulmonary artery systolic pressure: comparison with right heart catheterization: a retrospective cross-sectional study

Abstract

In this study, we found that all TR-related methods, including sPAP_ECHO, had comparable and good efficiency in PH screening. To make the assessment of sPAP_ECHO more accurate, attention should be paid to TR signal quality, sPAP_RHC level, and PAWP.
