Figure 3. Transthoracic echocardiography images obtained. Panel A demonstrating short-axis view of the left ventricular apex with significant loculated pericardial effusion. Panel B demonstrating short-axis view of the mid-left ventricle with circumferential, loculated pericardial effusion. Panel C demonstrates the inferior vena cava distended to 3.0 cm [normal 1.5–2.5 cm], and panel D demonstrates no respiratory variation of the distended inferior vena cava, indicative of a central venous pressure of at least 15 mmHg [normal 8–12 mmHg].
