Chronic Total Occlusion

When an artery of the heart is completely blocked for 30 or more days, it is called a chronic total occlusion (CTO). CTO is caused by a buildup of the fatty substance called plaque on the walls of the artery. This can lead to a decrease in blood flow to the heart, which prevents it from working correctly. When one or more of the coronary arteries is completely blocked, it can cause a heart attack. If the blockage occurs more slowly, it can cause chest pain (angina).

Some people will require coronary artery bypass graft surgery, which may clear the blockage. Another option for some people is percutaneous (through the skin) intervention. With this innovative technique, interventional cardiologists gently steer special guide wires and catheters through blockages. If you have been diagnosed with CTO, your doctor will discuss treatment options with you based on your individual case.
