Can you stent a 100% blocked artery?
“Patients typically develop symptoms when an artery becomes narrowed by a blockage of 70 percent or more,” says Menees. “Most times, these can be treated relatively easily with stents. However, with a CTO, the artery is 100 percent blocked and so placing a stent can be quite challenging.”Jul 18, 2017

Saphenous vein grafts (SVGs), used during coronary artery bypass graft surgery for severe coronary artery disease, are prone to degeneration and occlusion, leading to poor long-term patency compared with arterial grafts.

What is CABG in medical?
Surgery in which a healthy blood vessel taken from another part of the body is used to make a new path for blood around a blocked artery leading to the heart. This restores the flow of oxygen and nutrients to the heart. Also called aortocoronary bypass and coronary artery bypass grafting.
Overview
The left coronary artery normally arises from the aortic sinus above the left cusp of the aortic valve. The origin of the left coronary artery is called the left main coronary artery, and it bifurcates into the left anterior descending and the left circumflex artery.
Branches
The left coronary artery typically courses for 1 to 25 mm as the left main artery, and then bifurcates into the anterior interventricular artery (also called left anterior descending (LAD)) artery and the left circumflex artery (LCX).

What are the three arteries that run over the surface of the heart?
There is one artery on the right side, and two arteries on the left side. The one on the right is known as the right coronary. On the left side, which is the main side, we have the left anterior descending (LAD) that runs down the front of the heart and supplies the front and main wall, and then the left circumflex that supplies the sidewall. If you look carefully, a major artery called the left main artery supplies the LAD and the circumflex. The left main artery and even the LAD artery are so important that critical blockages in these arteries are known as the Widow Maker!
What is a moderate heart blockage?
A moderate amount of heart blockage is typically that in the 40-70% range, as seen in the diagram above where there is a 50% blockage at the beginning of the right coronary artery. Usually, heart blockage in the moderate range does not cause significant limitation to blood flow and so does not cause symptoms. Moderate coronary artery disease is treated much in the same way as mild disease, basically attention to risk factors, medications, and healthy lifestyle modification. Occasionally, heart blockage at the higher end of the moderate range (50-70%) may require additional testing to see if it is significant or not and may be responsible for symptoms.
What is 80% blockage?
Severe heart blockage is typically that in the greater than 70% range. This degree of narrowing is associated with significantly reduced blood flow to the heart muscle and can underlie symptoms such as chest pain and shortness of breath. In the diagram above, an 80% blockage can be seen at the beginning of the vessel. This is actually a bypass graft in someone that has had bypass surgery. The severe heart blockage caused symptoms and was treated with placement of a stent as can be seen in the picture. Sometimes, bypass surgery is required in the setting of multiple severe blockages.
What is the LAD in the heart?
LAD stands for left anterior descending artery. It is a coronary artery, which is the name given to arteries that supply the heart muscle with blood. The LAD is considered the most important of the three main coronary arteries and is almost always the largest. It’s called the LAD because is on the left side of the heart (left) it runs down the front wall of the heart (anterior descending). The Left anterior descend ing artery typically supplies over half of the heart muscle with blood, so twice as much as the other coronary arteries. For this reason, a major blockage at the beginning of the artery is often known as the Widowmaker!
How dangerous is a LAD artery?
Significant blockages of the LAD artery can be dangerous simply because the LAD supplies such a large territory. A stemi heart attack involving the LAD is typically more serious than other heart attacks. Usually a blockage of the LAD artery has to be more than 70% to cause significant problems. Even when it looks 70% blocked, more sophisticated tests are often used to determine whether a procedure is required to treat it. It’s now well accepted that a visual estimate of blockage is not a good way of determining how severe the disease it.
