In this study, we aimed to assess the value of cardiac CT parameters and PA obstruction scores (OS) in determining the echocardiographic RVD in low-intermediate risk PE patients.Materials-Methods A total of 120 patients with low-intermediate risk acute PE confirmed by contrast-enhanced multi-detector CT were included in the study. The patients were divided into two groups as with and without RVD.Results The demographic and clinical characteristics of patients with and without RVD were comparable (Table 1.)
