Angioplasty — its full name is percutaneous coronary intervention, or PCI — opens a heart artery narrowed by fatty plaque. A thin tube (catheter) is passed from the wrist or groin up to the heart, a small balloon is inflated at the blockage to widen it, and a stent — a tiny mesh scaffold, usually coated with medication (drug-eluting) — is left in place to hold the artery open. It is done under local anaesthetic, with no chest incision.
It is important to understand what angioplasty does and does not do. It treats a specific blockage, restoring blood flow — but it does not cure the underlying disease (atherosclerosis) affecting the rest of the arteries. Medication and lifestyle changes remain essential. And where blockages are extensive or involve the main left artery, bypass surgery may be the better option — a decision your cardiologist makes with you.

Angioplasty is used for significant coronary blockages — in an emergency during a heart attack, and in a planned way for stable disease causing chest pain. A coronary angiogram maps the blockages first, and a cardiologist decides whether angioplasty, bypass surgery or medication alone is the best route for you.
USUALLY SUITABLE
- A heart attack — emergency angioplasty (locally, at once)
- Stable angina limiting daily life despite medication
- One or a few discrete, reachable blockages
- Blockages confirmed significant on an angiogram
BYPASS MAY BE BETTER
- A blockage in the main left (left main) artery
- Complex disease across several arteries
- Diabetes with multivessel disease
- Where medication alone is the wiser first step 2
EVIDENCE
When it helps — the honest picture
Angioplasty is one of the best-studied procedures in medicine. What it achieves depends entirely on the situation, and we set that out plainly.

What this means for you. In a heart attack, minutes matter — you do not travel for that; you are treated at the nearest heart-attack centre. Planned angioplasty for stable disease is different: it is an excellent way to relieve chest pain that medication cannot control, and that is what an international patient usually travels for. A good cardiologist is honest about which situation is yours. 1,2
OUTCOMES
Benefits and limits
WHAT IT CAN DO
- Restore blood flow quickly, without open surgery.
- Save heart muscle and life during a heart attack. 1
- Relieve chest pain that limits daily life. 2
- Allow a short stay and fast return to activity.
WHAT IT CANNOT DO
- Cure the underlying artery disease.
- Reduce death or heart attack in stable disease. 2
- Replace medication and lifestyle change.
- Always be the right choice — sometimes bypass is better.
SAFETY
Risks and complications
Angioplasty is generally safe, especially at high-volume centres, but it carries some risk. These are what a cardiologist discusses at consent.
Access-site problems
Bruising or bleeding where the catheter went in is common and minor; a larger bleed is uncommon. The wrist route reduces this.
Re-narrowing & clotting
The stented artery can re-narrow or clot; drug-eluting stents and dual antiplatelet medication greatly lower this risk.
Heart or vessel injury
Rarely, the procedure can trigger a heart attack, damage the artery, or (very rarely) a stroke.
Contrast & kidneys
The X-ray dye can affect the kidneys, particularly if they are already impaired; this is checked and managed beforehand.
Your cardiologist gives you the full, personalised list at consent. This is a summary, not a complete account.
BEFORE TREATMENT
What to prepare for
The angiogram that maps your disease, the antiplatelet medication, and the timing of travel are the parts to plan for.
01Send your cardiac reports
Any angiogram, ECG, echo and blood results let a cardiologist judge whether angioplasty, bypass or medication is the right route — sometimes before you even travel.
02Understand the angiogram step
If no recent angiogram exists, one is done first to map the blockages; angioplasty often follows in the same sitting if suitable.
03Commit to the medication
After a stent, dual antiplatelet tablets are essential for a set period to prevent clots — stopping early is dangerous. Plan to continue them at home.
04Plan a short stay and safe travel
Expect one to two days in hospital and a short stay in India. The team confirms when it is safe to fly home.
05A heart attack is different
If you are having a heart attack, do not travel — call local emergency services. Angioplasty then is an emergency treated at once, wherever you are.
INDICATIVE COST
Cost in India
Single stent, from$3,500
Typical range$3,500–5,500
- Cardiologist and cath-lab charges
- Balloon and one drug-eluting stent
- Short hospital stay for the package
- Standard post-procedure medication in hospital
Indicative, not a quotation. The number of stents is the main reason cost varies. The same procedure often costs US$28,000 or more in the USA. A current itemised estimate is prepared after clinical review of your records.
Angioplasty results are best at high-volume cardiac centres with modern cath labs and a surgical back-up team on site. These are the accredited centres in our network.
FAQ
Questions patients ask
Is angioplasty better than bypass?
Neither is universally better — it depends on your anatomy. Angioplasty suits discrete blockages; bypass is often better for left-main or complex multivessel disease, especially with diabetes. 2 Your cardiologist and surgeon decide together.
Will it stop me having a heart attack?
For stable disease, angioplasty relieves symptoms but does not reduce future heart attacks or death compared with good medication. 2 That is why medication and lifestyle change remain central.
How long is the recovery?
Most people go home in a day or two and return to normal activity within about two weeks. The wrist route allows a particularly quick recovery.
Can I travel for a heart attack?
No. A heart attack is an emergency — call local services immediately. Planned angioplasty for stable, investigated disease is what international patients travel for.
What is a drug-eluting stent?
A stent coated with medication that slowly releases to stop the artery re-narrowing. It is the modern standard and reduces the need for repeat procedures. 3
Every clinical claim on this page traces to one of these. The benefit of angioplasty depends on the clinical situation.
1Primary percutaneous coronary intervention in ST-elevation myocardial infarction (STEMI).
SCAI expert consensus and meta-analyses. Primary PCI reduces mortality versus fibrinolysis and is the recommended emergency treatment for STEMI; it is time-critical and delivered locally.
2PCI versus optimal medical therapy in stable coronary artery disease (COURAGE; ISCHEMIA).
In stable CAD, PCI improves angina and quality of life but does not reduce death or myocardial infarction compared with optimal medical therapy.
3Drug-eluting stents in contemporary PCI.
Modern drug-eluting stents are the standard of care and reduce the need for repeat revascularisation compared with earlier bare-metal stents; dual antiplatelet therapy is required for a defined period after stenting.
