Venae cordis minimae

Dr Tim Luijkx and Dr Craig Hacking et al.

The venae cordis minimae (singular: vena cordis minima), meaning "smallest cardiac veins", also known as thebesian veins, are a small group of valveless myocardial coronary veins within the walls of each of the 4 cardiac chambers that drain venous blood directly into each of the respective chambers. They are most frequent in the right atrium and they are of little physiological or pathological significance.
