Figure Legends

Figure – Chest X-Ray
CXR demonstrates diffuse bilateral patchy airspace opacities consistent with COVID-19 pneumonia.
Figure – POCUS
Point of care ultrasound (POCUS) imaging in off-axis 4-chamber view demonstrates a severely dilated right ventricle (RV) and a large clot in transit in the right atrium (RA). LV, left ventricle. Video 1corresponds to this figure.
Figure – TEE
TEE in the approximate bicaval view demonstrates a large serpiginous clot in transit tumbling in the right atrium (RA) during different parts of the cardiac cycle during chest compressions. Video 2 corresponds to this figure.
Figure – TEE
TEE guidance of mechanical CPR. In this instance, the area of maximal compression (AMC) over the right ventricle (RV) is directed toward the left ventricular outflow tract (LVOT). This obliterates the LVOT and prevents proper left ventricular (LV) emptying. LA, left atrium.Video 3 corresponds to this figure.
Figure – TEE
TEE guidance of mechanical CPR. In this instance, the area of maximal compression (AMC) over the right ventricle (RV) is directed toward the body of the left ventricle (LV) and away from the left ventricular outflow tract (LVOT). This allows for proper LV emptying. LA, left atrium. Video 4 corresponds to this figure.
Figure – TEE
TEE demonstrates an agonal rhythm leading to cardiac standstill. RA, right atrium; RV, right ventricle; TV, tricuspid valve. Video 5corresponds to this figure.
