POCUS of lower extremities revealed no evidence of deep vein thrombosis (Fig. 1).
Apical four-chamber view of the heart on point of care ultrasound on ICU admission. Severely dilated RA and RV, and a small pericardial effusion were seen. The RA appears to bulge into the LA. No air bubbles were visualized in the chambers. RA, right atrium; RV, right ventricle; LA, left atrium; LV, left ventricle; *, small pericardial effusion.
