Subcostal 4-chamber view from a 2D echocardiogram shows a massive PE surrounding the LV, RA, and RV, which is strikingly reduced and shows diastolic collapse. The patient had severe hemodynamic compromise and tamponade physiology.
2D: 2-dimensional; LA: left atrium; LV: left ventricle; PE: pericardial effusion; RA: right atrium; RV: right ventricle.
