Coronary artery disease (percutaneous intervention)
What Is Percutaneous Coronary Intervention?
Percutaneous coronary intervention, commonly known as PCI or coronary angioplasty with stenting, is a minimally invasive procedure used to open blocked or narrowed coronary arteries without traditional open heart surgery.1
PCI is performed using a catheter, a thin, hollow tube inserted into a blood vessel, typically in the wrist or upper thigh, and guided through the vascular system to the affected coronary artery, where blockages caused by plaque buildup can be treated directly.2

Who Is a Candidate for PCI?
PCI is typically recommended for people with significant blockages caused by plaque buildup in one or more coronary arteries, particularly when blockages are causing chest pain or reduced blood flow to the heart muscle.2
It’s also commonly performed on an urgent basis following a heart attack, when restoring blood flow to the affected coronary artery as quickly as possible is critical to limiting damage to the heart muscle.2
The Procedure
Once the catheter reaches the narrowed section of the artery, the physician typically performs balloon angioplasty, inflating a small balloon at the tip of the catheter to widen the narrowed vessel.2
In most cases, this is followed by stenting, in which a small mesh framework called a stent is placed to hold the artery open. Many modern stents are drug eluting, meaning they release medication directly into the artery wall over time to reduce the chance that the vessel will narrow again at that location.2
Recovery
Because PCI is minimally invasive compared with open heart surgery, recovery is typically much shorter. Most patients are able to resume their usual activities within about a week following the procedure.2
With a drug eluting stent specifically, the likelihood that the treated artery will narrow again is generally less than 5%, reflecting significant improvement in long term outcomes compared with older stent technology.2
Risks and Complications
As with any invasive procedure, PCI carries risks, including bleeding, bruising or hematoma at the catheter access site, and allergic reaction to the contrast dye used during imaging.2
More serious, though less common, risks include abrupt closure of the treated vessel, coronary artery perforation or dissection, arrhythmia, and, rarely, death, risks that are carefully weighed against the benefits of restoring blood flow, particularly in urgent situations such as a heart attack.2
Results
For most patients, PCI successfully restores blood flow through the treated artery, relieving symptoms such as chest pain and reducing the risk of further heart damage. Because coronary artery disease is a chronic, ongoing process, however, PCI addresses the specific blockage treated rather than curing the underlying disease, and continued risk factor management remains important afterward.3
Why visual communication matters for percutaneous coronary intervention?
Patients preparing for PCI are often unfamiliar with how a catheter inserted in the wrist or thigh can reach and treat a blockage inside the heart, a journey that’s far easier to understand visually than through description alone.
Medical illustrations and animations can trace the catheter’s path from the access site to the coronary artery, show exactly how balloon angioplasty and stenting widen a narrowed vessel, and help patients understand both the procedure and its risks before giving informed consent.1
Visual communication can support:
- Coronary artery anatomy and blockage location education
- Catheter access and navigation animation
- Balloon angioplasty and stent placement demonstrations
- Drug eluting stent mechanism of action materials
- Patient informed consent resources
- Healthcare professional training
- Clinical trial and research communication
How Biotic Artlab supports percutaneous coronary intervention communication
At Biotic Artlab, we transform complex catheter based procedures and scientific information into clear, accurate medical illustrations and animations.
We collaborate with healthcare organizations, medical device developers, researchers, and publishers to create educational content that supports patient education, clinician training, and scientific communication.
Whether you’re explaining how a stent is placed, comparing PCI with surgical bypass, or presenting clinical trial findings, we create scientifically accurate illustrations and animations that improve understanding without oversimplifying the science.
Our services include:
- Medical illustration
- 3D medical animation
- Scientific illustration

Frequently Asked Questions
What is the difference between PCI and cardiac bypass surgery?
PCI is a minimally invasive catheter based procedure that treats a blockage from inside the artery, while bypass surgery reroutes blood flow around a blockage using a graft vessel and requires open heart surgery.1
How long does PCI take?
The procedure itself typically takes about one to two hours, though timing varies depending on how many blockages are treated and their complexity.
What is a drug eluting stent?
A drug eluting stent is a mesh device that releases medication directly into the artery wall over time, significantly reducing the chance the treated artery will narrow again compared with older stent designs.2
How long is recovery after PCI?
Most patients return to their usual activities within about a week, since the procedure is minimally invasive compared with open heart surgery.2
What are the risks of PCI?
Risks include bleeding or bruising at the access site, allergic reaction to contrast dye, and less commonly, vessel closure, perforation, or arrhythmia, all of which are discussed with patients before the procedure.2
Does PCI cure coronary artery disease?
No, PCI treats the specific blockage causing symptoms, but coronary artery disease is a chronic condition, so ongoing risk factor management remains important after the procedure.3
