Study Notes
Dominance of Vascular Supply
- Vascular supply to the heart can be right or left dominant.
- Dominance is determined by the origin of the posterior interventricular artery.
- Dominance describes which coronary arteries supply most of the heart structures.
Significance of Dominance
- Dominance is significant for the supply of the conduction system.
Coronary Arteries and Accompanying Veins
- Right coronary artery:
- Main branch of right coronary artery accompanies small cardiac vein.
- SA nodal branch accompanies right marginal vein.
- Inferior (Posterior) interventricular branch accompanies middle cardiac vein.
Left Coronary Artery
- Anterior interventricular branch accompanies great cardiac vein.
- Circumflex branch is a continuation of the great cardiac vein into the coronary sinus.
