Yes, it's possible to open a 100% blocked artery (Chronic Total Occlusion or CTO) using specialized interventional cardiology procedures like advanced angioplasty and stenting, often involving creative wire techniques to go through or around the blockage, or through bypass surgery, though lifestyle changes and medications help manage plaque and prevent worsening. While plaque buildup isn't fully reversible, these treatments restore blood flow, relieve symptoms, and improve quality of life, with modern success rates for CTOs now reaching 90-95%.
Treatment for chronic total occlusion: Even if your coronary artery is 100% blocked (also called chronic total occlusion), our interventional cardiologists can help. Our team specializes in using angioplasty and stents to open for chronic total occlusion.
Today, we have more treatment options. We can sometimes go around the blockage or work backward through the heart. We're now seeing success rates of 90% to 95%. If you are told that you have an artery that is 100% blocked, it's important to know that it can be treated.
When the artery eventually becomes completely blocked, the heart may supply that area through collaterals, which are branches of other arteries that supply the area. While a person can live with a chronic total occlusion, the most significant negative impact is on a person's quality of life.
While it is not possible to unblock clogged arteries, there are ways to slow the development of plaques, widen the arteries and reduce the chances of a heart attack or stroke.
CTO Percutaneous Coronary Intervention (CTO-PCI) – Special techniques and wires are used to either get through or around the blockage despite the 100% occlusion. A balloon is then inflated within the coronary artery to widen it and improve blood flow. Stents are subsequently placed to keep the artery patent.
PTAB is a minimally invasive approach that utilizes an endovascular technique using a patient's own blood vessels to create a bypass around the diseased or blocked area.
Making plaque disappear is not possible, but with lifestyle changes and medication they can shrink and stabilize. Doctors especially want to target the softer plaques before they rupture.
Symptoms are from the lack of blood flow to the heart. They may include chest pain and shortness of breath. A complete blockage of blood flow can cause a heart attack. Treatment for coronary artery disease may include medicines and surgery.
A blockage higher than 70% is classified as a severe cardiac blockage. This level of blockage can seriously restrict blood flow, causing symptoms such as chest pain and shortness of breath. Hence, doctors perform angioplasty.
When arteries are slightly occluded, medication and lifestyle modification may be enough to restore optimal blood flow. However, more severe cases may require the placement of a stent or even full bypass surgery. Stenting is a minimally invasive surgical procedure, but it still requires recovery time.
Dr. Skali emphasizes that regular exercise isn't just for those who are looking to prevent heart problems. It can help people whose heart muscle is already damaged. Although exercise can't clear existing plaque from clogged arteries, it can help prevent further accumulation.
Applying statins to control cholesterol is one of the most important preventive measures. Studies have found that taking statins caused plaque regression[24,25], but it took at least two years[26].
While bypass patients spend days recovering in the hospital and on average two months recovering at home, stenting is often an outpatient procedure. Most previous studies evaluating the two procedures have suggested that bypass surgery produces better and longer-lasting results.
Treatment Options for 100% Heart Blockage
A catheter is used to open the blocked artery, often followed by placing a stent. Less invasive with a shorter recovery period. May not be suitable for complex blockages. Cholesterol-lowering drugs and antiplatelet agents can help manage blockage.
An artery stent may not be recommended if: Your condition is mild. Your provider may monitor your condition, start you on medicine, and recommend heart-healthy lifestyle changes. You cannot take antiplatelet medicines for the amount of time needed after the stenting procedure.
You can live a long time with blocked arteries with appropriate management. They can often be treated without surgery, using minimally invasive procedures as well as medicine. “Medication is the cornerstone of treating chronic arterial blockages involving the heart arteries,” Dr. Vyas explains.
Among foods that contribute to clogged arteries are:
High blood pressure and high cholesterol
Cholesterol is the main component in plaque. Your liver naturally produces all the cholesterol you need, but you may consume extra cholesterol in the food you eat. As cholesterol increases in your blood, it can form fatty deposits (plaque) in your arteries.
Colchicine acts on many anti-inflammatory pathways, which translates to cardiovascular event reduction, plaque transformation, and plaque reduction. With the FDA's 2023 approval of colchicine for reducing cardiovascular events, a novel clinical pathway opens.
Green Tea: This healthy beverage contains procyanidins, which have been found to help prevent blood clots and promote healthy endothelium (the tissue that lines blood vessels and your heart). Apples: Apples (particularly Red Delicious and Granny Smith) are also rich in procyanidins.
Most of the time, bypass surgery is open-chest surgery. Its risks include heart attack, stroke, and death. Recovery usually takes at least 2 months. Whether you have surgery or not, having a heart-healthy lifestyle and taking medicine give you the best chance of living a longer, healthier life.
Subsequently, both single dose and chronic trodusquemine treatment resulted in attenuated plaque formation, as indicated by a decrease in total plaque area (Figure 5C,D).
You get medicines to help you relax. The amount of sedation needed for coronary angioplasty and stenting depends on your health conditions and why you're having the procedure. Usually you are awake during angioplasty. But some people may need a combinations of medicines that puts them to sleep during the procedure.
