Paddling Upstream With Point-of-Care Ultrasound to Diagnose Cardiac Ascites.

Ascites has multiple etiologies, including cirrhosis and heart failure, which can be differentiated by point-of-care ultrasound (POCUS). One cause of cardiac ascites that can be difficult to identify is portopulmonary hypertension (PPH), a rare disorder caused by pulmonary artery vasoconstriction due to advanced liver disease. POCUS can readily identify right ventricular dysfunction which can accelerate a PPH diagnosis. This case report describes the use of POCUS to work-up new onset ascites and expedite diagnosis of cardiac ascites due to PPH.
