From Wikipedia, the free encyclopedia
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]
