Koronarvenen

The coronary veins return deoxygenated blood from the myocardium back to the right atrium. Most venous blood returns via the coronary sinus. Coronary venous anatomy is highly variable, but is generally comprised of three groups:

• cardiac veins which drain into the coronary sinus:
  • great cardiac vein
  • middle cardiac vein
  • small cardiac vein
  • posterior vein of the left ventricle
  • vein of Marshall (oblique vein of the left atrium)
• the anterior cardiac veins which drain directly into the right atrium
• the venae cordis minimae (smallest cardiac veins a.k.a. Thebesian veins) which drain directly into all four chambers, but are most frequent in the right atrium.
