Coronary Circulation

Left Coronary Artery runs along the surface of the left atrium and then divides into:

• Left anterior descending artery
• Left circumflex artery

Left anterior descending supplies:

• Anterior wall of the left ventricle
• Interventricular septum
• Right bundle branch
• Fasciculus of the left bundle branch
• Branches further into the septal perforators and the diagonal arteries that supply blood to the walls of both ventricles
