Where do the anterior cardiac veins drain besides the right atrium?

The anterior cardiac veins primarily drain into the right atrium, but they can also drain into the right ventricle directly. This is important because the anterior cardiac veins are responsible for draining blood from the anterior portion of the right ventricle.

While the choice identifies the right marginal vein, this vein serves a different role as a tributary of the coronary sinus and is not directly related to the drainage of the anterior cardiac veins. The anterior cardiac veins bypass the coronary sinus which collects other venous blood from the heart.

Understanding the anatomy of cardiac venous drainage is crucial for cardiovascular perfusionists, as it has implications for procedures and interventions that may involve the heart's venous structures. Thus, recognizing how different veins connect and where they drain provides vital insights into overall cardiac function and pathology.
