Small cardiac vein

The small cardiac vein, also known as the right coronary vein,[1] is a coronary vein that drains 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]

Anatomical terminology

Location

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]

Function

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

Variations

The small cardiac vein may drain to the coronary sinus, right atrium, middle cardiac vein, or be absent.[4]
