Definition[Bearbeiten]
The ramus nodi atrioventricularis is a coronary artery branch that supplies blood to the AV node.
Anatomy[Bearbeiten]
The ramus nodi atrioventricularis usually arises from the right coronary artery (RCA) shortly before the posterior interventricular ramus (RIVP) leaves it. It runs in the epicardial fatty tissue under the base of the atrial septum forwards to the AV node.
In approximately 15 % of cases, the AV node is supplied from branches of the ramus circumflexus of the left coronary artery.
