Right Atrial Collapse With Hepatic Hydrothorax in Advanced Liver Disease.

Cardiac chamber collapse secondary to extrapericardial causes is rare. Focused cardiac ultrasound (FoCUS) in the emergency department can rapidly yield important clinical information and guide management in patients presenting with dyspnea, hypotension, or other cardiopulmonary complaints of uncertain etiology. We report a case of newly-diagnosed cirrhosis with massive ascites and large pleural effusions that distorted normal cardiac anatomy and venous return, in which FoCUS was essential in differentiating underlying pathology of this sick patient and guiding therapy.
