Blocked coronary arteries are one of the most common causes of heart attacks in India. Angioplasty is the procedure doctors use to open those blockages – restoring blood flow to the heart without open surgery. If your cardiologist has recommended this treatment, here is a plain-language explanation of exactly what happens, why it works, and what to expect.
Dr. Kulin Sheth is a leading interventional cardiologist in Ahmedabad with extensive experience in angioplasty and coronary artery disease. The information below reflects how he explains this procedure to patients in his clinic every day.
What Is Angioplasty?
Angioplasty, also called percutaneous coronary intervention (PCI), is a minimally invasive procedure that opens narrowed or blocked coronary arteries. These arteries supply oxygen-rich blood to the heart muscle. When fatty deposits, known as plaque, build up inside them, blood flow drops and the risk of a heart attack rises significantly.
During the procedure, a cardiologist threads a thin, flexible tube called a catheter through a blood vessel, usually at the wrist or groin and guides it to the site of the blockage. A small balloon on the tip of the catheter is inflated to push the plaque against the artery wall, widening the vessel. In most cases, a stent, a small mesh tube, is then placed inside the artery to keep it open permanently.
How Is Angioplasty Performed? A Step-by-Step Overview
The procedure takes place in a specialised cardiac catheterisation laboratory. Here is what happens at each stage:
- Local anaesthesia: The skin at the insertion site, typically the wrist, is numbed so the patient feels minimal discomfort throughout.
- Catheter insertion: A thin catheter is guided through a blood vessel toward the heart using real-time X-ray imaging (fluoroscopy).
- Locating the blockage: Contrast dye is injected to make the coronary arteries visible and pinpoint the narrowing.
- Balloon inflation: A small balloon on the catheter tip is inflated at the blockage site, compressing the plaque and widening the artery.
- Stent placement: A mesh stent is expanded inside the artery to hold it open and prevent re-narrowing.
- Confirmation and closure: Blood flow is verified, the catheter is removed, and the insertion site is closed.
The entire procedure generally takes between 30 minutes and two hours, depending on the number and complexity of blockages.
Benefits of Angioplasty
For patients with significant coronary artery disease, angioplasty offers several meaningful advantages over alternative treatments:
- Immediate symptom relief: Most patients notice a marked reduction in chest pain and breathlessness within hours of the procedure.
- Restored heart function: Reopening a blocked artery allows the heart muscle to receive adequate oxygen, improving its overall efficiency.
- Lower heart attack risk: Clearing severe blockages significantly reduces the likelihood of a future acute cardiac event.
- Shorter recovery than surgery: Because no large incisions are made, patients typically go home within one to two days rather than spending weeks recovering from open-heart surgery.
- Improved daily quality of life: Patients commonly report being able to walk, climb stairs, and exercise without the fatigue or pain they experienced before treatment.
What to Expect During Recovery
Recovery from angioplasty is generally straightforward. Most patients are discharged within one or two days and can return to light daily activity within a week. The procedure site, usually the wrist, may feel tender for a few days, which is normal.
Long-term heart health depends on lifestyle adjustments as much as the procedure itself. Doctors typically advise:
- Taking all prescribed medications consistently, including antiplatelet drugs to prevent stent clotting
- Eating a heart-healthy diet low in saturated fat, processed food, and excess salt
- Exercising regularly, even brisk walking for 30 minutes most days makes a measurable difference
- Keeping blood pressure and cholesterol within recommended ranges through monitoring and medication
- Quitting smoking and avoiding secondhand smoke exposure
- Managing stress through structured relaxation, adequate sleep, and social support
These changes are not optional extras, they are the primary way patients protect the treated artery and prevent new blockages from forming in other vessels.
Is Angioplasty Safe?
Yes. When performed by an experienced interventional cardiologist, angioplasty is a well-established, safe procedure with a high success rate. Advances in imaging technology, catheter design, and stent materials have significantly improved outcomes over the past decade.
As with any medical intervention, there are potential risks, including bleeding at the insertion site, rare allergic reactions to the contrast dye, or, in very uncommon cases, complications during the procedure. Your cardiologist will discuss your individual risk profile with you during the consultation.

Frequently Asked Questions About Angioplasty
Is angioplasty painful?
No. The procedure is carried out under local anaesthesia, so the insertion site is numb. Most patients feel pressure rather than pain during the procedure and report it being far more comfortable than they expected.
How long does the procedure take?
Typically between 30 minutes and two hours. More complex cases with multiple blockages take longer, but the majority of procedures fall within this range.
Can I live a completely normal life after angioplasty?
Yes, and many patients feel substantially better than they did before. With prescribed medication, a heart-healthy lifestyle, and regular cardiology follow-ups, most patients return to full daily activity within weeks and maintain good cardiac health for years.
What is the difference between angioplasty and bypass surgery?
Angioplasty opens blockages from inside the artery using a catheter and balloon. Bypass surgery creates new routes for blood to travel around blockages using vessels taken from elsewhere in the body. Angioplasty is less invasive and has a faster recovery, but the right choice depends on the number, location, and severity of blockages, something your cardiologist will evaluate carefully.
Can arteries become blocked again after angioplasty?
In-stent restenosis (re-narrowing of a treated artery) is uncommon with modern drug-eluting stents, which release medication to reduce scar tissue growth. Consistent medication and lifestyle changes reduce this risk further. Regular follow-up appointments allow your cardiologist to monitor the treated area.
When Chest Pain Should Not Wait
Chest pain, persistent breathlessness, and unexplained fatigue are not symptoms to manage quietly at home. They are the body’s signals that the heart is not receiving enough blood, and in many cases, angioplasty can resolve the problem quickly and safely.
If you are experiencing these symptoms, or if a recent diagnosis has raised questions about your coronary arteries, consult Dr. Kulin Sheth for an assessment. Early evaluation leads to better outcomes, and peace of mind.
