Caution against visual sinus node localization in procedures; leaves open need for histological or imaging validation.
Observational (n=45)
The sinus node is located at the cavoatrial junction but is usually indistinguishable to the naked eye, highlighting the need for caution during cardiac surgery in this area.
Gc et al. (2017) conducted an observational in Normal hearts (n=45). Anatomical and histological examination was evaluated on Visibility and location of the sinus node. The sinus node was indistinguishable to the naked eye in 97.77% of cases but could be identified histologically at the cavoatrial junction.
