On imaging, chest radiograph (CXR) portrayed bilateral pulmonary vascular congestion with small bilateral pleural effusions (Figure 1(a)). The patient's CXR postresuscitation showed worsening left pleural effusion without pneumothorax (Figure 1(b)).

Computerized tomography (CT) scan of the chest revealed large pericardial effusion and small bilateral pleural effusions right greater than the left side (Figure 2).

Bedside transthoracic echocardiogram confirmed moderate to large pericardial effusion with right ventricular collapse concerning for tamponade (Figure 3(a), Video 1). Transthoracic echocardiogram postresuscitation revealed left ventricular ejection fraction of 61-65% with near complete resolution of the pericardial effusion and new left pleural effusion (Figure 3(b), Video 2).
