Anatomical terminology [ edit on Wikidata]

The small cardiac vein, also known as the right coronary vein, ^[1] is a coronary vein that drains parts of the right atrium and right ventricle of the heart. ^[2] Despite its size, it is one of the major drainage vessels for the heart. ^[3]

Anatomy

Course

The small cardiac vein runs in the coronary sulcus between the right atrium and right ventricle, and opens into the right extremity of the coronary sinus. ^{[1] [2]}

Territory

The small cardiac vein receives blood from the posterior portion of the right atrium and ventricle. ^[2]

Variation

The small cardiac vein may empty into the coronary sinus, right atrium, or middle cardiac vein. It may be absent. ^[4]
