What Is Angioplasty? Procedure and Benefits

Angioplasty procedure and benefits — quick answers

What is angioplasty?

Angioplasty, or percutaneous coronary intervention (PCI), is a minimally invasive procedure that opens a blocked or narrowed heart artery using a small balloon and usually a stent, without opening the chest. Its goal is to restore blood flow, relieve chest pain and prevent heart attacks.

How is angioplasty done?

A thin catheter is inserted through the wrist or groin under local anaesthesia, the blockage is located with imaging, a balloon is inflated to open the artery and a stent is placed to keep it open. The procedure usually takes 30–90 minutes in a cardiac catheterisation lab.

Is angioplasty a major surgery?

No. It is a minimally invasive procedure done under local anaesthesia, is usually painless and does not involve opening the chest. Most patients go home within 1–3 days.

Who needs angioplasty?

Patients with persistent chest pain (angina), significant coronary artery blockage, a heart attack or its warning signs, or poor response to medication alone. If multiple major arteries or the main coronary artery are severely blocked, bypass surgery may be advised instead.

Does angioplasty cure heart disease?

No — angioplasty restores blood flow and relieves symptoms, but long-term heart health depends on medication adherence, lifestyle and dietary changes, and regular cardiac follow-up.

At Iswarya Hospital, Chennai, many patients arrive with chest pain, breathlessness, or abnormal heart test results caused by blocked or narrowed coronary arteries. One of the most effective treatments for this condition is angioplasty — a minimally invasive procedure designed to restore blood flow and protect the heart muscle from damage.

What Is Angioplasty?

Angioplasty, medically known as Percutaneous Coronary Intervention (PCI), is a procedure used to open blocked or narrowed arteries that supply blood to the heart.

At our hospital, we explain angioplasty as: "A way to gently widen a blocked heart artery using a small balloon and support it with a stent, without opening the chest."

The goal is simple: improve blood flow, reduce chest pain, and prevent heart attacks.

Why Do Patients Need Angioplasty?

Angioplasty is commonly recommended for patients with:

• Persistent chest pain (angina)
• Significant coronary artery blockage
• Heart attack or warning signs of one
• Poor response to medications alone

How We Perform Angioplasty

Our cardiology team follows a structured approach:

1. A thin catheter is inserted through the wrist or groin
2. The blocked artery is identified using imaging
3. A balloon is gently inflated to open the blockage
4. A stent is placed to keep the artery open
5. Blood flow to the heart is restored

The procedure is performed under local anaesthesia in our advanced cardiac catheterisation lab and usually takes 30 to 90 minutes.

Types of Angioplasty

• Balloon Angioplasty: Used to widen narrowed arteries
• Stent Angioplasty: A stent is placed to prevent re-narrowing
• Drug-Eluting Stents: Release medication to lower the risk of future blockage

Benefits Patients Experience

• Immediate relief from chest pain
• Improved blood flow to the heart
• Short hospital stay (usually 1–3 days)
• Faster recovery compared to open surgery
• Reduced risk of heart attack

Recovery and Ongoing Care

Recovery does not end with the procedure. At Iswarya Hospital, we guide patients through post-procedure monitoring, medication management, lifestyle and dietary advice, and regular cardiac follow-ups.

When Angioplasty May Not Be the Best Option

Angioplasty may not be ideal if multiple major arteries are severely blocked or the main coronary artery is involved. In such cases, we discuss alternative treatments like bypass surgery.
