PE is a life-threatening emergency that carries a mortality rate of up to 58% if it is not diagnosed in a timely fashion. Point-of-care cardiac, thoracic, and vascular ultrasonography is increasingly being used for the diagnosis and management of patients with PE.,, Focused lower extremity compression ultrasound by intensivists has been shown to accurately diagnose DVT. Among patients with large PE, findings on GDE include RV dilation, RV hypokinesis, flattening and paradoxical motion of the interventricular septum, tricuspid regurgitation, and lack of collapse of the inferior vena cava with inspiration. The RV diameter is larger than the left ventricular diameter, with evidence of decreased RV contractility. McConnell’s sign, in which there is severe RV free wall hypokinesis along with hypercontractility of the RV apex, can be seen with acute PE; however, it may also be detected in RV myocardial infarction.
