Interventional Cardiology in Hyderabad

What Is Interventional Cardiology?

Interventional cardiology is a specialised area of heart care that uses catheter-based techniques to diagnose and treat heart conditions. Instead of open surgery, the cardiologist makes a small puncture in a blood vessel, usually in the wrist or groin, and threads a thin tube called a catheter to the heart.

This approach allows the doctor to see inside the coronary arteries, open blockages, place stents and perform other treatments through a tiny opening. Because there is no large incision, patients typically experience less pain, shorter hospital stays and faster recovery compared with traditional surgery.

At Vijaya Heart Centre, our interventional cardiology department is equipped with a modern catheterisation laboratory (cath lab) and staffed by experienced interventional cardiologists who perform a wide range of diagnostic and therapeutic procedures.

Procedures Performed in Interventional Cardiology

Our cath lab handles a variety of procedures, including:

Coronary angiography: A diagnostic procedure that uses dye and X-ray imaging to see inside the coronary arteries and identify blockages. This is often the first step in understanding the extent of coronary artery disease.
Angioplasty and stenting: A balloon is used to open a blocked artery, and a stent (small mesh tube) is placed to keep the artery open. Drug-eluting stents are used to reduce the risk of the artery narrowing again.
Peripheral angioplasty: Similar to coronary angioplasty, but performed on arteries in the legs or other areas of the body that may be narrowed due to plaque buildup.
Balloon valvuloplasty: A balloon catheter is used to open a narrowed heart valve, most commonly the mitral or aortic valve.
Right and left heart catheterisation: Measurements taken inside the heart chambers to assess pressures and function, often used in the evaluation of heart failure and valve disease.

Who May Need an Interventional Cardiology Procedure?

An interventional procedure may be recommended if you have:

Chest pain or angina caused by narrowed coronary arteries
A heart attack, where emergency angioplasty can save heart muscle
Abnormal results on a stress test or other cardiac test
A coronary angiography showing significant blockages
Narrowed peripheral arteries causing pain in the legs while walking
A narrowed heart valve that has not responded to medication

Not every blockage requires an interventional procedure. Your cardiologist will review your test results, symptoms and overall health before recommending the most appropriate treatment plan.

What to Expect in the Cath Lab

Most interventional procedures are performed under local anaesthesia with light sedation, meaning you will be awake but comfortable throughout. Here is a step-by-step overview:

Before the procedure: You will be asked to avoid eating for several hours. Your medical team will review your medicines and advise which ones to continue or pause.
During the procedure: A small needle is used to access a blood vessel in the wrist or groin. A catheter is guided to the heart using X-ray imaging. Dye is injected to visualise the arteries.
Treatment: If a blockage is found, a balloon may be inflated to open the artery and a stent placed to maintain blood flow.
After the procedure: The catheter is removed and pressure is applied to the access site. You will be moved to a recovery area and monitored for several hours.

The procedure itself usually takes between 30 minutes and two hours, depending on the complexity. Most patients go home the same day or the next morning.

Recovery After an Interventional Procedure

Recovery from catheter-based procedures is generally quick. The wrist access site usually heals within a few days, while groin access may take slightly longer. You will be given clear instructions about wound care, activity levels and when to resume driving.

After angioplasty and stenting, you will be prescribed blood-thinning medicines to prevent clots from forming inside the stent. It is very important to take these medicines exactly as directed and never stop them without speaking to your cardiologist.

A cardiac rehabilitation programme is often recommended after interventional procedures to help you recover strength and adopt a heart-healthy lifestyle.

FAQs About Interventional Cardiology

Catheter-based procedures are generally less invasive than open surgery and carry lower risks for most patients. However, every procedure has some risk, and your cardiologist will discuss the specific benefits and risks for your situation.

Modern drug-eluting stents are designed to last many years. The stent itself becomes part of the artery wall over time. Continuing your prescribed medicines and maintaining a healthy lifestyle are the best ways to keep the artery open.

Patients with desk jobs may return to work within two to three days. Those with physically demanding roles may need one to two weeks. Your doctor will give you specific guidance based on your procedure and recovery.

Yes. Regular follow-up appointments are important to monitor your recovery, check your medicines and assess your heart health. Your cardiologist will schedule visits at appropriate intervals.

While re-narrowing is possible, drug-eluting stents have significantly reduced this risk. If it does occur, a repeat angioplasty or other treatment may be recommended. Regular follow-up helps catch any issues early.
