Right marginal branch of right coronary artery
The right marginal branch of right coronary artery (or right marginal artery) is the largest marginal branch of the right coronary artery. It follows the acute margin of the heart. It supplies blood to both surfaces of the right ventricle.

Structure
The right marginal branch is the largest branch to split off from the right coronary artery.[1][2] It often anastomoses with the nearby parallel posterior interventricular artery, which itself is usually a continuation of the right coronary artery.[3]
Variation
The right marginal branch may reach the distal part of the posterior interventricular sulcus.[3]
Function
The right marginal branch primarily supplies the right ventricle.[2][4]
