It is also known as the left main coronary artery ( abbreviated LMCA ) and the left main stem coronary artery ( abbreviated LMS ). It is one of the coronary arteries.

Sometimes an additional artery arises at the bifurcation of the left main artery, forming a trifurcation ; this extra artery is called the ramus or intermediate artery. 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 and all its eventual branches. A `` first septal branch '' is sometimes described. Additional images This gallery of anatomic features needs cleanup to abide by the medical manual of style.
