Patients from hospitals across the state and western Pennsylvania turn to 

for innovative, expert-led care for relief from severe coronary artery disease.

For patients with coronary occlusion or chronic total occlusion (CTO) — a blockage of a coronary artery of 100% and has been present for at least 90 days — CTO procedures can be complex due to the chronicity of the blockage.

While few cardiologists in the region perform CTO proceduresdue to their complexity, AHN is proud to offer 

Specialized equipment, techniques, and talent

CTOs differ from the acute artery blockages that cause heart attacks, requiring specialized expertise and cutting-edge technology for optimal procedure results.

At AHN, our talented Interventional Cardiologistsutilize advanced tools, like precision-engineered wires, guide catheters, and imaging systems designed specifically for navigating and clearing chronic blockages. With this approach, we maximize success rates while prioritizing patient safety and comfort.

Recovery from a CTO procedure is comparable to that of a standard Percutaneous Coronary Intervention (PCI) or stent placement, with most patients returning home the next day.

Following the CTO procedure, patients generally report significant improvement, with relief from debilitating symptoms like chest pain, shortness of breath, and fatigue.

To ensure long-term success, AHN coordinates follow-up care with each patient’s local cardiology team, providing comprehensive support throughout recovery.

If your patient is suffering from symptoms of a severe artery occlusion and you think they may require a CTO procedure, skilled 

at AHN Cardiovascular Institute are here to provide a consultation or second opinion — ensuring the best possible treatment plan for your patient.
