Chronic Total Occlusion

You Can Make a Difference

“For me, there is not another aspect in cardiology where cardiologists are able to provide the type of benefits that we see. Patients tell us literally on the table, they feel like they can take a breath again. For the first time in years they don’t have this constricting feeling around their chest."

– J. Aaron Grantham, MD

Common Occurrence

CTOs are very common, occurring in as many as 30% of patients with significant coronary artery disease.1,2


Patients with CTOs are most often treated with medical therapy or coronary artery bypass graft (CABG) rather than PCI.


Recent meta-analyses and large registries have shown that successful CTO PCI is associated with symptom relief, a reduction in long-term mortality, and a lower need for coronary artery bypass graft (CABG) surgery.3,4,5
