Related parts of the anatomy
Origin
There are a series of ventricular branches that arise from the right coronary artery and can be divided into anterior and posterior ventricular branches.
Between the origin of the right coronary artery and the origin of the right marginal artery, there are a series of small branches that supply the anterior aspect of the right atrium and ventricle. Of these branches there are usually two or three anterior ventricular branches. There are also two or three posterior ventricular branches that originate between the right marginal artery and the posterior interventricular sulcus.
Course
The ventricular branches course inferiorly along the anterior and posterior (inferior) aspects of the right ventricle.
Branches
The ventricular branches ramify as they descend towards the apex along the right ventricle.
Supplied Structures
The ventricular branches contribute to the supply of the right ventricle.

Right Coronary Artery
A normal right coronary artery origin is defined as a vessel that arises within the mid third of the right sinus of Valsalva perpendicular to the aortic sinus wall, and a normal left coronary artery origin is defined as a vessel that arises within the mid third of the left sinus of Valsalva and perpendicular to the sinus wall.
