Anterior cardiac veins
Sternocostal surface of heart.(Anterior cardiac veins not labeled, but visible at left.)

Anatomical terminology []

The anterior cardiac veins (or anterior veins of right ventricle), comprising three or four small vessels which collect blood from the front of the right ventricle and open into the right atrium; the right marginal vein frequently opens into the right atrium, and is therefore sometimes regarded as belonging to this group.

Unlike most cardiac veins, they do not end in the coronary sinus. Instead, these veins drain directly into the anterior wall of the right atrium.
