Can CT Pulmonary Angiography Allow Assessment of Severity and Prognosis in Patients with Pulmonary Embolism?
Movie 1. The clot is shown moving freely in the lumen of the left atrium on four-chamber multiplanar images.
Movie 2. The whole cardiac cycle is shown. Note the flattening and moderate paradoxical motion of the interventricular septum toward the LV. Flattening is maximal in early diastole, when the gradient pressure is maximal between the ventricles. At this time, the LV starts relaxing, while RV contraction continues, thereby reversing the transseptal pressure gradient.
