Pericardial effusion

Apical four chamber view from a two-dimensional echocardiogram shows a moderate pericardial effusion (PE) surrounding the right atrium (RA), right ventricle (RV), and left ventricle (LV), but not the left atrium (LA). RA motion is exaggerated, but the chamber is not compressed. At cardiac catheterization, the patient had normal hemodynamics.
