dc.description.abstractTo evaluate the accuracy of cardiac computed tomography (CT) parameters and pulmonary artery (PA) obstruction (OS) scores in determining the echocardiographic right ventricular dysfunction (RVD) in hemodynamically stable patients with acute pulmonary embolism (PE). A total of 120 patients with acute PE were included in the study. Right ventricle/left ventricle ratio (RV/LV); PA axial diameter; superior vena cava (SVC) axial diameter; and Ghanima, Miller, Qanadli, and Mastora obstruction scores were obtained using CT. RVD was assessed by echocardiography. The patients were divided into two groups based on the presence or absence of RVD. RV/LV ratio, SVC axial diameter, PA axial diameter, and Miller, Qanadli, and Mastora scores were significantly increased in the RVD group. Multivariate logistic regression analysis showed that RV/LV ratio [OR 6.36 (2.02-279.46 95 % CI), p = 0.01] and PA axial diameter [OR 5.02 (1.02-1.26 95 % CI), p = 0.03] were independent predictors of echocardiographic RVD. Predictive values of these parameters were improved when combined with other intragroup cutoff values. A cutoff value for the RV/LV ratio of > 1.08 had 81.43 % sensitivity, 52.08 % specificity, 71.3 PPV, and 65.8 NPV for prediction of RVD. Tomographic axial diameters enable more accurate predictions of RVD than OS scores do.en_US
