Abstract
Background: The sinoatrial nodal artery (SANA) is highly variable vessel which supplies blood to the sinoatrial node. Due to its variability and susceptibility to iatrogenic injury, our study aimed to assess the anatomy of SANA and determine the prevalence of its anatomical variations.
Aim: To study the prevalence of variable origin of the Sinoatrial nodal artery.
Material and Methods: Study was conducted in the department of Anatomy in association with the department of Cardiology of M.L.N Medical College, Allahabad. A total number of 100 subjects (both male and female) were enrolled. Angiographic films of the cases were analyzed for the origin of SA nodal artery. For the Right Coronary Artery, LAO view, and for the Left Coronary Artery, RAO view were analyzed.
Result: Out of 100 cases studied, SANA was seen to be arising from RCA in 66% of cases, from circumflex branch of LCA (LCX) in 12 % of cases and from both the coronary arteries (RCA+LCX) in 15% cases.
Conclusion: The distribution of the SA nodal artery makes us understand the possible ischaemic etiology of the sinusal nodal syndrome and helps the surgeon accordingly.
