The dorsal interventricular vein of the heart (Vena interventricularia dorsalis cordis, better known by the abbreviation VI **VCD**) is one of the large veins in the coronary circulatory system. It collects blood from the atria and pulmonary circulation and transfers it to the right atrium. This vein is located in close proximity to the interventricular septum, which is why it got its name.
Anatomy and location As mentioned above, the vein has its roots in the venous system of the ventricles and connects them to the right atrium. This is a widely distributed, dilated vein with many branches. It passes through the interventricular septum, piercing it and exiting into the central vascular bed. So it turns out to be divided into right and left sides. The left branch often entwines the heart valves. The main branches are divided into ascending (ascendentes) and descending (descendentes)
