The artery of the atrioventricular node: an anatomic study based on 38 injection-dissections

Abstract: The origin and course of the artery of the atrioventricular node (AAVN) was studied in 45 anatomic specimens by the method of injection-dissection in 38 human hearts removed at medicolegal autopsies from black Senegalese subjects. Though sometimes double, the AAVN is classically solitary. Its coronary origin, which is always distal, occurred on the right side in the great majority of cases, at the level of the "U-turn of James", and on the left side at the level of the terminal portion of the circumflex a.

“…In 80-87% of patients, atrioventricular nodal artery arises from distal RCA and penetrates to the posterior interatrial septum base at the level of heart crux. In the remaining patients, it arises from terminal part of LCX (8-13%) or rarely from left anterior descending artery (2-10%) [2,3,24]. Pejković et al [21] defined AVNA as the first and the longest inferior septal perforator branch that usually arose from RCA (90%) and infrequently from LCX artery (10%).…”

“…The AAVN can have a right or left coronary artery origin, though the AAVN most commonly originates from the right coronary artery, that is, in 90% of patients. [9,10] The distal segment of the AVN has a dual blood supply in 80% of human hearts from the same AAVN and the left anterior descending artery. It is an indispensable component of the cardiac conduction system axis and the only electrical conduit from the atria to the ventricles.…”

“…Based on previous studies, the nutritious artery of the SAN is the sinuatrial node artery (SANA) 1520 ; the AVN is mainly supplied by the atrioventricular node artery (AVNA) 16, 2022 and can sometimes also be supplied by the first septal artery 21, 23 ; and the nutritious arteries of the HBB are the AVNA and the first septal artery of the left anterior descending artery 24 . The nutritious arteries of the RBB are the AVNA and the septal arteries 19, 24 .…”
