Dr Siddhant N Yadav › Angioplasty
Angioplasty in Andheri East
Opening a blocked coronary artery with a stent — including the complex, long-standing blockages that other centres often turn down.
What angioplasty is
The coronary arteries are the small vessels that supply blood to the heart muscle itself. When one narrows or blocks, the muscle downstream is starved — that is what causes angina, and if the blockage is sudden and complete, a heart attack.
Angioplasty opens that artery from the inside. A thin tube is passed to the heart, usually through an artery at the wrist, a balloon is inflated at the narrowing, and a stent — a small metal scaffold — is left behind to hold the vessel open. There is no surgical cut and no general anaesthetic. Most people are awake throughout.
When it is advised
- During a heart attack, where opening the artery quickly saves heart muscle
- Angina that limits what you can do, despite medication
- A significant blockage found on angiography, CT angiography or a stress test
- Blockages causing repeated hospital admissions
Not every blockage needs a stent. Some are better treated with medication alone, and some are better served by bypass surgery. That decision depends on how many vessels are involved, where the narrowing sits, how the heart is pumping, and what other conditions you have. It should be an honest conversation, not a foregone conclusion.
Complex angioplasty and CTO
A chronic total occlusion is an artery that has been completely blocked for months or longer. These are the hardest cases in interventional cardiology: there is no channel to follow, the blockage is often hard and calcified, and crossing it takes specialised wires, dedicated techniques and considerable time.
Many centres will tell a patient with a CTO that nothing more can be done. Often something can. Dr Yadav's practice includes this complex coronary work, and his case entry won third place overall — and first among Indian entries — at CHIP-CTO India 2026 in New Delhi.
Complex cases are frequently guided by intravascular ultrasound (IVUS), a camera-like probe inside the artery itself. It shows the true size of the vessel and how well the stent has expanded — detail an ordinary angiogram cannot give, and which is linked to better long-term results.
What to expect on the day
- You will be asked not to eat for a few hours beforehand
- Local anaesthetic at the wrist or groin; you stay awake
- A straightforward procedure takes under an hour; a complex CTO can take considerably longer
- Most people go home the next day, some the same day
- Light activity within days; driving and full activity usually within a week
Afterwards
Blood-thinning tablets after a stent are not optional. Stopping them early is one of the few genuinely dangerous things a patient can do, because a stent can clot shut. If any other doctor or dentist asks you to stop them, ring the clinic first.
The stent fixes one blockage. It does not fix the disease that caused it. Blood pressure, cholesterol, diabetes, smoking and weight all still need attention, and follow-up matters as much as the procedure.

Common questions
Is angioplasty painful?
Not usually. Local anaesthetic numbs the wrist or groin where the tube goes in. Some people feel brief pressure or a flush of warmth when the balloon inflates. You are awake and can talk to the team throughout.
How long will I be in hospital?
Commonly one night. Simple cases done through the wrist are sometimes same-day. A long, complex CTO procedure may mean a slightly longer stay.
Where are the procedures done?
At the attached hospitals in Andheri, Bandra and Vile Parle rather than at the clinic itself. The clinic can arrange it at whichever is most convenient for you.
Will I need to take medicines forever?
You will need blood thinners for a defined period after the stent — the duration depends on your case. Medicines for cholesterol, blood pressure or diabetes usually continue long term, because they treat the underlying disease.
Can a blocked artery be opened years later?
Often, yes. That is exactly what CTO angioplasty is for. Whether it is worth doing depends on whether the muscle beyond the blockage is still alive and still causing symptoms — which a stress test or cardiac MRI can answer.
