Key result
Mapping septal perforator anatomy prevents iatrogenic injury to the septum and conduction system during cardiac procedures.
Why the study?
Because septal perforating arteries are not directly visible externally, their anatomy and variations might be overlooked, risking vessel damage during common cardiac procedures.
Understanding the anatomy of the septal perforating arteries is crucial to avoid vessel damage during common cardiac procedures such as CABG, PCI, and aortic valve replacement.
Reinforces septal perforator awareness in interventions; leaves open prospective validation of risk reduction.
The septal perforating arteries of the heart usually branch off from the anterior and inferior interventricular arteries and supply the interventricular septum and the conduction system therein. Since the septal perforating arteries are not directly visible from the outside of the heart, their anatomy and variations might be overlooked. However, the septal perforating arteries have their unique anatomy that needs to be recognized to avoid the damage of the vessels especially during common cardiac procedures such as the coronary artery bypass graft, percutaneous coronary intervention, and aortic valve replacement. A better understanding of these important arteries will help physicians to enhance the overall cardiac care for their patients. Therefore, this article discusses the anatomy, the relationship to the conduction system of the heart and the clinical significance of the septal perforating arteries.

Sung Deuk Kim (2019) conducted a review in Coronary artery anatomy. Anatomical knowledge of septal perforating arteries was evaluated. Understanding the unique anatomy of the septal perforating arteries is critical to avoid damaging the interventricular septum and conduction system during cardiac procedures.
