Anatomical dissection of 150 adult hearts revealed the SA node artery originated from the right coronary artery in 63% of cases, and the AV node artery from the right coronary artery in 90%.
Observational (n=150)
Detailed anatomical knowledge of the SA and AV node arterial supply variants can assist in avoiding complications during arrhythmia treatments and mitral valve surgery.

May guide nodal artery awareness in ablation and mitral procedures; leaves open prospective clinical correlation of these variants.
Pejković et al. (2008) reported an observational. Anatomical characteristics of SA and AV node arteries was evaluated on Origin of the SA and AV node arteries. Anatomical dissection of 150 adult hearts revealed the SA node artery originated from the right coronary artery in 63% of cases, and the AV node artery from the right coronary artery in 90%.
