A pericardial vein is any vein that drains blood from the area around the heart, specifically the pericardium, and typically empties into the azygos or brachiocephalic veins. It helps in the circulation of blood around the heart tissues. The pericardium is the double-walled sac containing the heart and the roots of the great vessels.
