Anatomical description of the deep venous channel from the anterior vestibular wall of the right atrium.
The deep venous channels in the walls of the right atrium are not routinely described in medical treatises although their existence has been remarked from some time. Our study demonstrates that the right atrium is opened for some of the anterior veins of the heart through a venous channel located deep in the myocardium of the vestibule of the right atrium. We suggest that no Thebesian veins drain into this channel. We achieved anatomical dissection in 14 adult human cadaveric hearts, which had been fixed in formalin solution, and we found the channel in 75% of cases. These channels were measured, photographed and presented in detail. We highlighted the importance of the proximity with the tricuspid annulus in order to avoid incidents during tricuspid annuloplasty. The authors intend that through a qualitative study to draw attention to such a structure often ignored. This vascular structure and its role in cardiac physiology and pathology have not been investigated yet. Although not constant, specialists in cardiology and cardiac surgery should be informed about this basic detail on the endocardium morphology.
