Fig. 2From: Pulmonary arterial hypertension due to antiphospholipid syndrome initially mimicking chronic thromboembolic pulmonary hypertensionSerial changes in the echocardiography images (A), hemodynamic parameters of right heart catheterization and 6MWD (B). A Echocardiography images showed an enlarged right ventricle and atrium at the first three time points. After 38 months (Jun 2021), a follow-up echocardiogram showed a normal-sized right ventricle. B Hemodynamic parameters of right heart catheterization: PAWP, mPAP, PVR, and 6MWD showed marked improvement at the end of the follow-up period (Jun 2021). mPAP, mean pulmonary arterial pressure; PAWP, pulmonary arterial wedge pressure; PVR, pulmonary vascular resistance; and 6MWD, six-minute walking distanceBack to article page
