Can a total occlusion be stented?
Coronary arteries with severe blockages, up to 99%, can often be treated with traditional stenting procedure. Once an artery becomes 100% blocked, it is considered a coronary chronic total occlusion, or CTO. Specialized equipment, techniques and physician training are required to open the artery with a stent.
How is chronic total occlusion treated?
Treatment options for CTO have traditionally been limited due to the complexity of opening up completely blocked arteries using catheter-based techniques. Historically, physicians often recommended coronary artery bypass grafting (CABG), or open-heart surgery, as the only option for treating these blockages.
What happens when a coronary artery is completely blocked?
A completely blocked coronary artery will cause a heart attack. The classic signs and symptoms of a heart attack include crushing chest pain or pressure, shoulder or arm pain, shortness of breath, and sweating. Women may have less typical symptoms, such as neck or jaw pain, nausea and fatigue.
Which treatment would be best in treating a completely blocked coronary artery?
Coronary bypass surgery Sometimes, surgery is needed to fix a blocked artery. Some options are: Coronary angioplasty and stent placement. This procedure is done to open clogged heart arteries.
What is chronic total occlusion procedure?
Coronary chronic total occlusion (CTO), defined as complete occlusion of a coronary artery for at least 3 months with thrombolysis in myocardial infarction (TIMI) grade 0 flow, represents one of the most complex situations in the field of interventional cardiology.
Can you live with a blocked artery?
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.
Can blocked arteries be treated with medication?
In serious cases, medical procedures or surgery can help to remove blockages from within the arteries. A doctor may also prescribe medication, such as aspirin, or cholesterol-reducing drugs, such as statins.
Can heart blockage be treated without surgery?
Through angioplasty, our cardiologists are able to treat patients with blocked or clogged coronary arteries quickly without surgery. During the procedure, a cardiologist threads a balloon-tipped catheter to the site of the narrowed or blocked artery and then inflates the balloon to open the vessel.
What causes occlusion of coronary arteries?
Most occlusions are caused by either a blood clot or the buildup of fatty plaque in the arteries (atherosclerosis). A blood clot can form at the site of occlusion, or it can travel from another area through the bloodstream and block an artery.

What drug will be used to dilate the coronary arteries?
Drugs that dilate large coronary arteries, such as nitroglycerin and the calcium channel-blocking agents, can dilate these stenotic segments. This dilation may contribute to the relief of myocardial ischemia by increasing coronary blood flow.
Can you live with 100 blocked LAD artery?
A widow maker is when you get a big blockage at the beginning of the left main artery or the left anterior descending artery (LAD). They're a major pipeline for blood. If blood gets 100% blocked at that critical location, it may be fatal without emergency care.
Diagnosis
- Coronary artery disease is the narrowing or blockage of the coronary (heart) arteries, as shown in the top illustration. After an interventional procedure, the coronary artery is opened, increasing blood flow to the heart. Coronary artery disease is the narrowing or blockage of the coronary arteries caused by atherosclerosis. Atherosclerosis is the...
