left coronary artery
The diagonal branch is one of the terminal branches of the left coronary artery, as well as the circumflex and anterior interventricular branches, when it splits into three or four branches.
What does the diagonal artery supply?
The diagonal branch supplies the anterolateral papillary muscle and the anterior and lateral portions of the left ventricular wall. The circumflex artery follows the coronary sulcus to the left portion of the heart and further divides into the left marginal artery and posterior left ventricular artery.
Can diagonal artery be stented?
The patency of the diagonal artery graft in bifurcating lesions of the LAD and diagonal artery is always questionable due to competition of flow from the LITA graft. However, the efficacy of diagonal coronary artery stenting in patients undergoing robotic LITA-to-LAD anastomosis is not well defined.
Which artery is called Widowmaker?
A widowmaker is an informal term for a heart attack that involves 100 percent blockage in the left anterior descending (LAD) artery, says Stanley Chetcuti, M.D., an interventional cardiologist at the University of Michigan Frankel Cardiovascular Center.
Is the diagonal artery part of the LAD?
Diagonal branches of the left anterior descending coronary artery supply blood flow to the anterior and anterolateral walls of the left ventricle. There are usually denoted as D1, D2, D3, etc. There are termed “diagonal” due to them branching from their parent vessel at acute angles.
What is the survival rate of a Widowmaker?
