==Superior vena cava== | |||
The superior vena cava contains oxygen-poor blood returning from the tissue in the upper portion of the body (pulmonary circulation). The superior vena cava is close to the roof of the right atrium. The superior vena cava is transthoracically not good to bring into image, only supraclavicular (no standard recording). Better to spend (the last part of) the VCS with TEE in image. The VCS can be constricted by space-occupying processes, it is also called the VCS Syndrome. | |||
