About the origin of the sinus node artery

We read with interest the Letter to the Editor by Nerantzis et al. entitled “A secret pathway of the sinus node artery”. The use of post-mortem angiography in the above report is impressive in showing also small coronary branches not easily evaluable during autopsy. From an anatomical point of view, some more morphological details would be useful to stress the novelty of the finding. In the above manuscript the authors describe “a unique and hitherto not reported variation” in which the left circumflex (LCX) and the sinus node (SN) arteries “originated with a common trunk branching (3.1mm long, internal diameter 1.4mm) from the posterior wall of the left main coronary artery”. In the literature, the SN arteries are known to frequently originate from the proximal segment of the ...
