Loss of right ventricular outflow function in pulmonary hypertension
Right ventricular outflow tract (RVOT) function is not systematically quantified by three-dimensional (3D) echocardiography. We tested the hypothesis that loss of RVOT function in pulmonary hypertension (PH) is related to disease severity independently of other echocardiographic parameters. In this observational study, patients with PH, disease controls, and a matched healthy control group underwent 3D echocardiography and RVOT analysis using ReVISION software. The study included 43 patients (38 with PH, 5 disease controls) and 43 healthy controls.
