The blood supply of the AV node is from the atrioventricular nodal branch. The origin of this artery is most commonly (80–90% of hearts) a branch of the right coronary artery, with the remainder originating from the left circumflex artery. [4] [5] [6] This is associated with the dominance of the coronary artery circulation.
Oct 30, 2023 · The atrioventricular node (also known as the AV node) is a collection of specialized cardiac muscle cells, which are bundled together to form a node within the wall of the interatrial septum. It is an important component of the cardiac conduction system and is responsible for transmitting impulses that originate in the sinoatrial (SA) node to the ventricles of the heart.

The atrioventricular nodal branch is a coronary artery that supplies arterial blood to the atrioventricular node, which is responsible for initiating muscular contraction of the ventricles. The AV nodal branch is most often a branch of the right coronary artery .
Nov 7, 2024 · The RCA also provides blood to the atrioventricular (AV) node through the AV nodal artery. The AV node is a key component in the heart’s electrical conduction system, receiving impulses from the SA node and transmitting them to the ventricles. The RCA’s role in perfusing the AV node ensures that electrical signals are properly conducted ...
Jul 24, 2023 · The sinoatrial nodal branch of the RCA provides blood to the SA node, and the atrioventricular nodal artery delivers blood to the AV node. The marginal branch of the right coronary artery provides blood supply to the lateral portion of the right ventricle. The posterior descending artery branch supplies blood to the inferior aspect of the heart.

Oct 30, 2023 · The right coronary artery gives rise to several cardiac arteries/heart vessels that vascularize the majority of structures located in the right aspect of the heart. These structures usually include: the right atrium, right ventricle, the interatrial and interventricular septa, atrioventricular (AV) node and sinuatrial (SA) node.

Jul 25, 2023 · The atrioventricular (AV) node is a small structure in the heart, located in the Koch triangle,[1] near the coronary sinus on the interatrial septum. In a right-dominant heart, the atrioventricular node is supplied by the right coronary artery. The purpose of this structure is to connect the electrical systems of the atria and the ventricles, providing electrical impedance from the atria and ...
