TEE - longitudinal view of the superior vena cava.
SVC: superior vena cava.
This view is obtained from the view of the vessels at the base of the heart (film 13). By centering the image on the superior vena cava in the transversal view and then progressively turning the multiplane probe to about 90°, a longitudinal view of this vein is obtained. Using motion mode, it is then easy to measure the diameter of the superior vena cava at end-expiration and its variations during ventilation. On this film, the patient presented no respiratory variations in the size of the superior vena cava.
