The superior vena cava (SVC, also known as the cava or cva) is a short, but large diameter vein located in the anterior right superior mediastinum. Embryologically, the SVC is formed by the left and right brachiocephalic veins (also known as the innominate veins) that also receive blood from the upper limbs, eyes, and neck.

There is no valve that divides the SVC from the right atrium, which conducts blood from right atrial and right ventricular contractions upwards into the internal jugular vein (seen as the jugular venous pressure) and sternocleidomastoid muscle.
