Widow maker is an alternative name for the anterior interventricular branch of the left coronary artery. [9] [3] The name widow maker may also apply to the left coronary artery [10] or severe occlusions to that artery. [11] [12] This term is used because the left main coronary and/or the left anterior descending supply blood to large areas of ...
Posterior descending artery; Ramus or intermediate artery; Right coronary artery. Right marginal artery; 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 ...
[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 ...
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 around the pulmonary trunk.
The circumflex branch of left coronary artery (also known as the left circumflex artery or circumflex artery [citation needed]) is a branch of the left coronary artery. It winds around the left side of the heart along the atrioventricular groove (coronary sulcus). It supplies the posterolateral portion of the left ventricle. [1]

In normal anatomy, three essential coronary arteries are identified: right coronary artery (RCA), left anterior descending artery (LAD) and left circumflex artery (LCx). LAD and LCx usually originate from the bifurcation of a common vessel known as left main trunk or left coronary artery (LM or LCA). [citation needed]
The anastomosis supplying the left anterior descending branch is the most significant one and usually, the left internal mammary artery is harvested for use. Other commonly employed sources are the right internal mammary artery, the radial artery , and the great saphenous vein .
