Relationship between clot burden in pulmonary computed tomography angiography and different parameters of right cardiac dysfunction in acute pulmonary embolism.

Background: Pulmonary computed tomography angiography (CTA) contains a wealth of information regarding the diagnosis and impact of acute pulmonary embolism (PE). Echocardiography remains the recommended examination to detect signs of right ventricular (RV) dysfunction in patients with shock or hypotension following PE.

Objectives: To detect the relationship between clot volume in pulmonary CTA and different parameters of RV dysfunction assessed by echocardiography and pulmonary CTA in patients with acute PE.
