Abstract Purpose The aim of this study was to determine the pulmonary artery computed tomography obstruction index ratio (PACTOIR) in patients who have been diagnosed with acute pulmonary embolism (APE) with multi-slice computed tomography (MSCT) and to research the predetermination efficiency of right ventricular dysfunction (RVD) compared with echocardiography (ECHO). Materials and methods One hundred patients (50 males, 50 females), who had ECHO findings and were diagnosed with APE, were subsequently examined in this study. Patients who had RVD on ECHO, tricuspid regurgitation, and pulmonary hypertension parameters that were completely positive were accepted to have RVD. Results RVD was identified in 52 patients (52 %) on echocardiography. The PACTOIR value for patients with RVD were evaluated to be significantly higher than those

without RVD (41 ± 17 vs 20 ± 12 %, p 3.4 cm at the basal plane or >3.8 cm at the midplane was used to designate RV dilatation as per the guidelines. Right atrium (RA) size was measured on the minor-axis dimension extending from the lateral border of the RA to the interatrial septum [9]. Valvular regurgitations were measured via the combination of color flow jet Doppler signal intensity and vena contracta width according to guideline recommendations [10]. Systolic pulmonary artery pressure was calculated as shown previously [9]. Patients were recorded to have RV dysfunction in this study if they had RV dilatation, accompanied by either decreased RV fractional area change (RVFAC,
