​Chronic Total Occlusion Intervention

Chronic total occlusion (CTO) is a complete blockage of a coronary artery that has been in place for 30 days or longer. CTOs are very common, occurring in 15 to 20 percent of patients with significant coronary artery disease. The condition can cause severe angina (chest pain) and lead to a lower quality of life.

Most CTO patients are treated with medical therapy or bypass surgery. However, interventional cardiologists at Sacred Heart Medical Center offer a minimally invasive procedure that can reroute blood flow around the blockage and restore selected patients' quality of life.

Hybrid CTO Approach

Through a small incision in the femoral artery near the groin, our interventional cardiologists use a catheter to gain access to the blockage and reroute the blood flow around it. Thanks to advances in technology and technique, our team of experts can approach blockages from either the front or back, via collateral vessels that develop over time. This "hybrid" approach provides more treatment options and improved patient outcomes, with more than 95 percent of blockages successfully treated in our cardiac catheterization lab.

Patient Benefits

Patients with successful interventions typically experience immediate and dramatic symptom relief.
