A coronary occlusion, or coronary artery disease, is the partial or complete obstruction of blood flow in a coronary artery. This condition was first discussed in 1910 by Sir William Osler. [1] This condition slows or blocks the supply of oxygen-rich blood to the heart. [2]

2022年8月3日 · A chronic total occlusion is a complete blockage in one of your coronary arteries that has been present for three months or longer. A CTO restricts blood flow to your heart and can cause serious complications, including a heart attack.

2024年6月14日 · Coronary artery disease often develops over many years. 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.

When a coronary artery becomes completely blocked—not simply narrowed—it is called a total occlusion. And if a complete blockage lasts for 3 months or longer, doctors refer to it as “chronic total occlusion,” or CTO for short.

2024年6月14日 · To diagnose coronary artery disease, a healthcare professional examines you. You are usually asked questions about your medical history and any symptoms. If you have symptoms of coronary artery disease such as chest pain or shortness of breath, tests may be done to check your overall health.

Chronic coronary total occlusion (CTO) occurs when either the left main or right coronary artery — one of the arteries that delivers oxygen-rich blood to your heart — has become completely blocked or occluded for three months or longer.

2023年7月24日 · A coronary chronic total occlusion (CTO) is defined as 100% occlusion of a coronary artery for a duration of greater than or equal to 3 months based on angiographic evidence.

2023年7月17日 · A chronic coronary occlusion is most often discovered on coronary angiography due to anginal chest pain, possible revascularization due to angina refractory to medical therapy, or diagnostic testing suggestive of myocardial ischemia or after a positive stress test.

A chronic total occlusion (CTO) is a complete or near-complete blockage in one or more coronary arteries that lasts three months or longer. The coronary arteries are the blood vessels that supply blood to the heart. A CTO commonly develops in people with coronary artery disease.
