Imaging of right ventricle in predicting the development of chronic thromboembolic pulmonary hypertension (CTEPH)

Abstract

There is increasing evidence in the literature emphasizing the importance of right ventricular(RV) imaging in the prognosis of pulmonary hypertension. We aimed to investigate the predictive role of RV dysfunction parameters assessed by echocardiography(ECHO) and thorax computed tomography(CT) in developing CTEPH. Patients diagnosed with pulmonary embolism(PE) prospectively included. All patients underwent ECHO and CT within 24hours after admission. We repeated CT and ECHO after 6 months and 1 year to assess the incidence of CTEPH and assess the predictive role of RV dysfunction factors in the development of CTEPH. Twenty-two patients (7 of whom were male) with a mean age of 53.9±17.9years were included; CTEPH developed in two patients during the follow-up. Baseline PO2 levels were significantly lower in patients with CTEPH(61.5±11.4vs77.8±25.2,p
