What Is Coronary Intervention (PCI)?

Coronary artery disease — where the arteries supplying the heart become narrowed or blocked — is one of the leading causes of heart attacks and angina. Coronary intervention, also known as Percutaneous Coronary Intervention (PCI) or angioplasty, is a proven, minimally invasive procedure to open these blockages.

PCI involves passing a thin wire through a narrowed coronary artery and using a small balloon to open the blockage. A stent — a tiny metal scaffold — is then placed to keep the artery open permanently. The entire procedure is performed through a small puncture in the wrist (radial approach) – meaning you have no cuts, no stitches and a much faster recovery compared to bypass surgery.

Who Needs Coronary Intervention?

Your cardiologist may recommend PCI if you have significant chest pain (angina) that is not controlled with medications, a positive stress test indicating reduced blood flow to the heart, an acute heart attack requiring emergency treatment, or coronary artery disease confirmed on angiogram that is suitable for stenting.

Conditions Treated

PCI (Percutaneous Coronary Intervention), commonly known as angioplasty, is used to treat:

Treatment Options

Benefits of the Procedure

When Surgery/Treatment is Recommended

Significant blockage in one or more coronary arteries
Persistent chest pain despite medications
Reduced blood flow affecting heart function
During or after a heart attack
High risk of future cardiac events

Non-Surgical Alternatives

Step-by-Step Procedure Explanation

A catheter is inserted through the wrist or groin artery.
The catheter is guided to the blocked coronary artery.
A balloon is inflated to open the blockage.
A stent is usually placed to keep the artery open.
The catheter is removed and recovery begins.

Advanced Technology Section

Not all coronary blockages are straightforward. Our interventional cardiology team is trained in handling complex cases, including:

Calcified (hardened) arteries requiring rotational atherectomy or intravascular lithotripsy
Bifurcation lesions at the branching points of arteries
Left main coronary artery disease
IVUS (Intravascular Ultrasound) and OCT (Optical Coherence Tomography) guided stenting for precision results
Drug-coated balloon (DCB) therapy as an alternative to stenting in selected cases

Risks & Complications

Bleeding or bruising at the catheter insertion site
Blood clot formation within the stent
Re-narrowing of the treated artery (restenosis)
Irregular heart rhythms (arrhythmias)
Allergic reaction to contrast dye or medications
Damage to the blood vessel or artery
Heart attack or stroke (rare)
Infection or kidney complications (uncommon)

Serious complications are uncommon, and PCI is generally considered a safe and effective procedure when performed by experienced specialists.

Recovery Timeline

Most patients are discharged within 24–48 hours. You will be prescribed dual antiplatelet therapy (DAPT) — aspirin and a second blood-thinning tablet — to be taken for a period of time as advised by your cardiologist. Regular follow-up is essential to monitor your recovery and adjust medications as needed.
