The computed tomographic (CT) pulmonary angiogram appearances
of acute right ventricular dysfunction due to massive pulmonary embolus
in a patient are described. Abnormal findings comprised right
ventricular dilatation, interventricular septal shift, and compression
of the left ventricle. These changes resolved following thrombolysis.
Use of CT pulmonary angiography to diagnose pulmonary emboli is
increasing. Secondary cardiac effects are established diagnostic
features shown by echocardiography. These have not been previously
described but are important to recognise as they may carry important
prognostic and therapeutic implications.
