What is the diagonal branch?

The diagonal branch comes off the LAD and runs diagonally across the anterior wall toward its outer or lateral portion, supplying the anterolateral portion of the left ventricle. The first diagonal artery generally originates after the branch point of the LAD and the first septal perforator.

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.

How many diagonal branches are there in LAD?

The Left Main coronary artery typically bifurcates into two branches, the left anterior descending artery (LAD) and the circumflex artery (Cx). Occasionally, a third branch called Ramus Intermedius may arise between the LAD and the Cx.

What percent of blockage requires a stent?

By clinical guidelines, an artery should be clogged at least 70 percent before a stent should be placed, Resar said. “A 50 percent blockage doesn’t need to be stented,” he said.

Is artery blockage reversible?

Can atherosclerosis be reversed or slowed down? The disease is progressive, and, unfortunately, current treatments can’t melt it away. However, there are things that can be done to slow its development and dramatically reduce the chances of a heart attack or stroke.

How stent is placed in heart?

To place the stent, a small sheath, plastic tube, is placed in the groin or wrist artery. A catheter is guided through the artery into the part of the coronary artery that is blocked. The stent is inserted along with a balloon catheter and expands when the balloon is inflated.

How long can you live with one heart artery?

Survival at 6 years: 85% for one artery.

What are the 4 main arteries of the heart?

The right coronary artery, the left main coronary, the left anterior descending, and the left circumflex artery, are the four major coronary arteries. Blockage of these arteries is a common cause of angina, heart disease, heart attacks and heart failure.

Should I get a stent or not?

If you are having a heart attack, a stent is absolutely needed, stresses Donald Lloyd-Jones, M.D., chair of the Department of Preventive Medicine at the Northwestern University Feinberg School of Medicine in Chicago. Since a clot has completely blocked an artery, your heart muscle is starved of oxygen.
