Procedure guide · Interventional cardiology
Coronary angioplasty widens a narrowed coronary artery with a small balloon, and a stent is a short mesh tube left in place to help keep it open. The NHS explains that the procedure is done through an artery in the groin, wrist or arm under local anaesthetic. An interventional cardiologist decides whether it suits your arteries after studying your angiogram.
What are coronary angioplasty and stenting?
The procedure takes place in a catheter laboratory with X-ray equipment. The NHS describes the steps. A local anaesthetic numbs the skin. A thin tube called a catheter is guided along an artery to the heart. A fine wire is passed across the narrowing and a balloon is inflated there to press back the fatty deposits. If a stent is used it sits on the balloon, expands with it and stays in the artery.
The NHS describes two main stent types. Bare metal stents are uncoated. Drug-eluting stents are coated with medicine that lowers the chance of the artery narrowing again. People with stents usually take blood-thinning medicines afterwards. The NHS says aspirin is often taken long term with a second antiplatelet medicine for a set period.
Who may a cardiologist consider for angioplasty?
Angioplasty is one way to treat coronary heart disease. Others include medicines and bypass surgery. The NHS notes that an angiogram is often done first to map the narrowings. Sometimes the angioplasty follows straight away in the same session.
The choice depends on the number and position of narrowed arteries and on conditions such as diabetes or kidney disease. Your cardiologist decides whether a stent, bypass surgery or medicines suit you. If you have already had an angiogram at home, a cardiologist in India can review it before you travel.
Which reports does a cardiologist usually ask for?
The NHS says you will need an assessment beforehand, which may include blood tests and a general health check. For a remote review ask whether the hospital needs:
- the angiogram images and report, if one has been done
- a recent ECG and echocardiogram
- a stress test report, if you have one
- kidney function tests, since contrast dye is used
- your full medicine list, especially warfarin or other blood thinners
- diabetes medicines and recent HbA1c, because timings may need changing
How do I plan an angioplasty trip?
The NHS notes that many people go home the same day and some stay overnight. Plan for the time your cardiologist advises, not a fixed number of days. Stages usually include remote review, a written plan and estimate, visas, arrival and pre-procedure tests, the procedure and a short period of observation before you are cleared to fly.
Medicines matter most after a stent. Take enough of your prescribed antiplatelet medicines to last until you can see your doctor at home. Ask whether the brands you receive in India are available in your country. Never stop them without medical advice. Carry the stent details, often given on a card or in the discharge summary, in case you need care later.
What should I ask the hospital before booking?
- Will the angiogram and angioplasty be done in one session or separately?
- Will you go through my wrist or my groin?
- What type of stent do you plan to use and why?
- How long will I take each blood-thinning medicine?
- What happens if the angiogram shows I need bypass surgery instead?
- Will I receive a stent card and a full procedure report?
Who decides
IndiaMedica does not give medical advice. Your treating specialist decides whether this procedure suits you, the treatment plan, how long you stay and when it is safe to fly.
Questions people ask
What if the angiogram shows I need surgery instead?
This can happen. The angiogram may show narrowings better treated with bypass surgery or medicines. Ask the hospital before you travel how it would handle that, what extra time it might need and how the estimate would change. Your cardiologist and surgeon explain the options to you before any decision.
Can I stop my blood thinners once I feel well?
Do not stop them without speaking to your cardiologist. After a stent these medicines help keep the artery open. The NHS explains that a second antiplatelet medicine is usually prescribed for a set period. Plan how you will get further supplies at home.
