Anterior cardiac veins

The anterior cardiac veins (or anterior veins of right ventricle) are a variable number of small veins (usually 2-5)^[1] which drain blood from the anterior portion of the right ventricle into the right atrium.^[1][2]

Anatomy

The right marginal vein frequently opens into the right atrium,^[1] and is therefore sometimes regarded as belonging to this group.^{[citation needed]}

Fate

Unlike most cardiac veins, the anterior cardiac veins do not end in the coronary sinus; instead, they drain directly into^[2] the anterior wall of^{[citation needed]} the right atrium.^[2]
