Posterior descending artery; The left coronary artery arises from the aorta within the left cusp of the aortic valve and feeds blood to the left side of the heart. It branches into two arteries, the left anterior descending and the left circumflex. The left anterior descending artery perfuses the interventricular septum and anterior wall of the ...
[citation needed] The left coronary artery typically runs for 10–25 mm, then bifurcates into the left anterior descending artery, and the left circumflex artery. [ 1 ] The part that is between the aorta and the bifurcation only is known as the left main artery (LM), while the term "LCA" might refer to just the left main, or to the left main ...
The circumflex artery supplies the posterolateral left ventricle and the anterolateral papillary muscle. It also supplies the sinoatrial nodal artery in 38% of people. It supplies 15–25% of the left ventricle in right-dominant systems. If the coronary anatomy is left-dominant, the circumflex artery supplies 40–50% of the left ventricle.
Soon after it emerges, the brachiocephalic artery divides into the right common carotid artery and the right subclavian artery. [4] There is no brachiocephalic artery for the left side of the body. The left common carotid artery and the left subclavian artery come directly off the aortic arch. Despite this, there are two brachiocephalic veins. [5]
The circumflex artery arises from the left coronary artery and follows the coronary sulcus to the left. Eventually, it will fuse with the small branches of the right coronary artery. The larger left anterior descending artery (LAD), is the second major branch arising from the left coronary artery. It follows the anterior interventricular sulcus ...
