Branches of left coronary aery are all of the following except:

The left coronary aery, which is usually larger than the right coronary aery, supplies the major pa of the hea, including the greater pa of the left atrium, left ventricle, and ventricular septum.It arises from the left posterior aoic sinus of the ascending aoa.It then enters the atrioventricular groove and divides into an anterior interventricular branch and a circumflex branch. BranchesThe anterior interventricular (descending) branch /left anterior descending (LAD) runs downward in the anterior interventricular groove to the apex of the hea.The anterior interventricular branch supplies the right and left ventricles with numerous branches that also supply the anterior pa of the ventricular septum. One of these ventricular branches (left diagonal aery) may arise directly from the trunk of the left coronary aery.The left circumflex aery (LCX) is the same size as the anterior interventricular aery. It winds around the left margin of the hea in the atrioventricular groove. A left marginal aery is a large branch that supplies the left margin of the left ventricle down to the apex. Anterior ventricular and posterior ventricular branches supply the left ventricle. Atrial branches supply the left atrium.Posterior interventricular branch: It is typically a branch of the right coronary aery (80%, known as right dominance). Alternately, the Posterior interventricular branch can be a branch of the left circumflex coronary aery (20%, known as left dominance) which itself is a branch of the left coronary aery
