What is anterior cardiac vein?

The anterior cardiac vein is a vein that drains blood from the front portion of the heart. It runs along the anterior surface of the heart and empties into the right atrium. It is a small vein that contributes to the overall venous drainage of the heart. The anterior cardiac vein is not as well-known or studied as other major veins of the heart, but it plays an important role in the overall circulation of blood within the cardiovascular system.
