Chronic Total Occlusion

If you’re living with chronic total occlusion — even after bypass surgery or stents — chances are your quality of life is not what you want it to be. Community Heath Network’s interventional cardiologists are here to help.

Chronic Total Occlusion Leads to More Serious Problems

If you have severely blocked arteries, even if you have been told that "nothing can be done," you may have a condition called chronic total occlusion (CTO). That kind of total blockage (100 percent) keeps blood from flowing normally to your heart with the oxygen and nutrients it needs. Are you experiencing these symptoms of blocked arteries? They could be warning signs and shouldn’t be ignored.

  • Chest pain, pressure or tightness
  • Shortness of breath, trouble breathing
  • Fatigue
  • Nausea
  • Rapid or irregular heartbeat
  • Pain in the upper body and arm

Minimally-Invasive Treatment for Chronic Total Occlusion

Community Health Network interventional cardiologists specialize in minimally-invasive heart procedures for blocked arteries that do not require open-heart surgery. Similar to a heart catheterization, CTO procedures are performed in a heart cath lab. Some patients may even go home the same day. As one of the most experienced CTO programs in central Indiana, we put that experience to work for you.

Talk to the Heart Specialists at Community

Even if you’ve had stents or bypass surgery before, you don’t have to live with chronic total occlusion. Our interventional cardiology team gets to know you to better understand you and your heart health, so we can decide together on the right care plan.
