Diagnosis Heart & Vascular

Chronic Total Occlusion
Diagnosis

The primary test used to diagnose CTO is a coronary angiogram. A catheter (thin, flexible tube) is threaded through a blood vessel in the wrist or groin to an artery in the heart; then a harmless dye that shows up well on X-rays is injected through the catheter. The images reveal blocked arteries as well as how well the heart muscle and valves are functioning.

Our providers review your angiogram results and tailor a treatment plan to your condition and needs. You will then have a clinic visit – either in person or by video – in which we discuss the recommended treatment, including its risks, benefits and what to expect.
