Echocardiographic diagnosis and clinical implications of wide-open tricuspid regurgitation for evaluating right ventricular dysfunction in the emergency department.

The tricuspid regurgitation pressure gradient (TRPG) reflects the difference in pressure between the right ventricle and right atrium (ΔP). Its estimation by echocardiography correlates well with that obtained using right-heart catheterization. An elevated TRPG is an important marker for identifying right ventricular dysfunction in both the acute and chronic settings.

Point of Care Ultrasound Diagnosis of Maxillary Artery Pseudoaneurysm in the Emergency Department.

A pseudoaneurysm results from a tear in a vessel wall. This leads to extravasation of blood into adjacent tissue and eventual formation of a fibrous sac that maintains continuity with the lumen. These vascular injuries very rarely occur in deeper vessels of the face (e.

Invasive Fungus Balls Diagnosed by Point-of-Care Ultrasound in the Emergency Department.

Background: Genitourinary tract fungus balls are a rare complication of urinary tract infections (UTI). They arise from dense aggregations of hyphae that combine with surrounding urothelial cells and debris. Symptoms can progress to urosepsis and systemic dissemination.
