Parasternal 4-chamber view from a 2-dimensional echocardiogram shows a massive pericardial effusion (PE) in a patient with hemodynamic compromise and tamponade physiology. The effusion surrounds the LV and RV, which is severely compressed.
LA: left atrium; LV: left ventricle; PE: pericardial effusion; RA: right atrium; RV: right ventricle.
