TEE deep transgastric view of the right upper pulmonary vein and pulmonary artery taken before and after compression release. The four upper panels were imaging taken before tamponade evacuation, while the four lower panels were taken after. Note the narrowing of the RUPV due to external compression (Panel A, arrow) compared with after release (Panel E). Similarly, narrowing of the PA due to external compression was captured (Panel C, arrow) compared with after release (Panel G). VTI was shown at the right side of the captured images. Reduced blood flow passing through the compressed RUPV (Panel B) compared with after release (Panel F). Increased VTI was also noted at the level of PA prior and after the evacuation (Panels D and H). Legend: A, aorta; PA, pulmonary artery; RA, right atrium; RUPV, right upper pulmonary vein.
