PCI, also known as coronary angioplasty with stenting, is a minimally invasive procedure used to open blocked coronary arteries and restore blood flow to the heart muscle. The Clinic is renowned for treating highly complex cases with excellent patient outcomes.

PCI is a catheter-based procedure that addresses the buildup of fatty, waxy plaque (atherosclerosis) in the coronary arteries, which can lead to coronary artery disease (CAD) or acute events like a heart attack (myocardial infarction).

Key Aspects of PCI Treatment

The Cleveland Clinic's approach to PCI emphasizes advanced techniques, comprehensive patient evaluation, and a focus on complex and high-risk cases.

Procedure Overview

A PCI procedure typically involves the following steps:

Access: A small hollow tube (sheath) is inserted, usually through a blood vessel in the arm (radial access) or groin (femoral access). Cleveland Clinic reports a high use of the radial approach, which is associated with fewer bleeding complications.
Catheter Insertion: A thin, hollow tube (catheter) is guided through the sheath to the heart.
Visualization: A contrast dye is injected, and X-ray imaging (fluoroscopy) is used to pinpoint the blockage.
Opening the Artery: A tiny balloon at the tip of the catheter is inflated at the site of the blockage to compress the plaque and open the artery.
Stent Placement: In most cases, a small mesh tube called a stent (often a drug-eluting stent to prevent re-narrowing) is deployed to keep the artery open after the balloon is deflated and removed.

Specializations and Complex Interventions

The Clinic's Interventional Cardiology section is a referral center for complex, catheter-based treatments, including:

Chronic Total Occlusion (CTO) PCI: Treatment of coronary arteries that have been 100% blocked for typically more than three months. The Clinic has significantly high success rates (around 85%) for this complex procedure, often using advanced techniques and a hybrid approach.
Intracoronary Brachytherapy: A specialized treatment involving the localized delivery of radiation inside a blood vessel to treat in-stent restenosis (re-narrowing of the artery within a previously placed stent). This is available at only a few centers nationally.
Adjunctive Support Devices: Routine use of ventricular support devices when necessary for high-risk patients undergoing complex PCI.
Diagnostic Tools: Extensive use of advanced diagnostic tools like Intravascular Ultrasound (IVUS) and Fractional Flow Reserve (FFR) to accurately assess the severity of blockages and guide treatment decisions.
