Atrioventricular Nodal Branch of Right Coronary Artery

Ramus nodi atrioventricularis arteriae coronariae dextrae

Read more


The atrioventricular nodal branch arises from the right coronary artery near the posterior interventricular sulcus.


The atrioventricular nodal branch has a short course from the external surface of the heart near the origin of the posterior interventricular artery. It then courses inferiorly through the interatrial septum towards the atrioventricular node.


There are no named branches of the atrioventricular nodal branch.

Right Coronary Artery

ScienceDirect image

The right coronary artery (RCA) is initially imaged in the LAO 30-degree view, which displays the proximal and distal RCA well, and the artery appears as the letter C. To evaluate the right posterior descending artery (rPDA) and posterior lateral branches (rPL), RAO 0-degree, cranial 30-degree view is utilized.
