Figures

Figure 1.
Figure 1.
Computed tomographic scan of the patient’s chest with intravenous contrast. (A) Axial view cephalad to the tracheal bifurcation. Note the large mediastinal mass (MM), compressing the trachea (white arrow). (B) Coronal view. The mass severely compresses the left lung (black arrow), left innominate vein, and superior vena cava (white arrow).
Figure 2.
Figure 2.
Transthoracic echocardiography after return of spontaneous circulation. (A) Apical four-chamber view demonstrates an enlarged right ventricle (RV) with bowing of the intraventricular septum (IVS) into the left ventricle (LV) during systole. (B) Parasternal short axis view at the midpapillary level shows RV dilation, IVS bowing, and LV compression (“D-sign”). (C) Subxiphoid view also shows an enlarged RV with deviation of the IVS into the LV during systole. EFF  =  pericardial effusion; LA  =  left atrium; LIV  =  liver; RA  =  right atrium.
Figure 3.
Figure 3.
Computed tomographic scan of the patient’s chest with intravenous contrast after stabilization with extracorporeal life support. (A) Axial view at the level of the pulmonary artery bifurcation. Note the near-complete contrast filling defect in both the left and right pulmonary arteries, suggestive of a saddle pulmonary embolism (arrows). Also note the massively dilated pulmonary artery (PA), which is 1.5-fold larger than the adjacent aorta (Ao). (B) Axial view at level of right and left ventricles (RV and LV, respectively). The RV is dilated with intraventricular septal flattening and poor contrast flow into the LV, secondary to acute RV failure.
