Revisiting coronary artery–cameral vessels: clarifying ‘MICROFISTULAE’ and moving beyond eponymous terms

titled 'Coronary artery microfistulae, Thebesian veins, or vessels of Wearn?,' published in Oxford Medical Case Reports [1].Their discussion highlights a persistent conundrum in cardiovascular anatomy: the varied terminology applied to small vascular channels connecting coronary arteries to cardiac chambers.Terms such as 'microfistulae,' 'arterioluminal vessels,' 'arteriosinusoidal vessels,' 'vessels of Wearn,' and 'Thebesian veins' have all been employed, at times interchangeably, leading to confusion regarding whether these structures are pathologic or merely normal variants.This commentary aims to clarify why the eponym 'vessels of Wearn' is not recommended for standard usage today.Instead, I advocate consistently using 'coronary artery-cameral vessels,' a descriptor that more accurately conveys these channels' anatomic and embryologic nature, and propose that they be formally recognized within future international classification of diseases (ICD) classifications as either physiologically normal or 'abnormally prominent' when implicated in pathology.
