TAVI: Getting a New Aortic Valve Without Open-Heart Surgery

What Is the TAVI Procedure for Aortic Valve Disease?

Your heart has four valves that keep blood flowing in the right direction. The aortic valve is one of the most important — it opens and closes with every heartbeat to push oxygen-rich blood out to the rest of your body. Over time, especially after the age of 65, this valve can become stiff and narrow, a condition called aortic stenosis.

When the valve does not open fully, the heart has to work much harder. Left untreated, severe aortic stenosis can cause breathlessness, chest pain, fainting, and a significant reduction in quality of life.

For many decades, the only way to replace a worn-out aortic valve was open-heart surgery — a major operation that involves stopping the heart and splitting the breastbone. That has changed dramatically with Transcatheter Aortic Valve Replacement, known as TAVI (sometimes written as TAVR).

TAVI is a procedure that allows a cardiologist to implant a brand-new artificial valve inside the diseased one — through a thin, flexible tube called a catheter — without opening the chest. It is one of the most significant advances in heart care in recent years.

How Does the TAVI Procedure Work?

The word transcatheter simply means "through a catheter." Here is a straightforward look at what happens, step by step.

1. Preparing for the Procedure

Before TAVI, the heart team — which usually includes an interventional cardiologist, a cardiac imaging specialist, and an anaesthetist — carries out a thorough assessment. This includes:

• An echocardiogram (ultrasound of the heart) to measure the valve and assess heart function
• A CT scan of the chest, aorta, and leg arteries to plan the exact route the catheter will take
• Blood tests and other routine checks

This detailed planning is what makes modern TAVI so precise and safe.

2. During the Procedure

TAVI is typically performed under sedation (you are relaxed and comfortable but not fully unconscious, though general anaesthesia is used in some cases). The most common route is through the femoral artery — the large artery in the groin — though other routes such as through the wrist or chest wall are sometimes used.

Here is what happens:

• A small puncture is made in the groin — no large incision needed.
• A thin, flexible catheter (tube) is guided through the artery, up the aorta, and to the heart.
• The cardiologist uses live X-ray imaging (fluoroscopy) and echocardiography to navigate with great precision.
• A compressed, folded replacement valve — mounted on a small expandable frame — is carefully positioned inside the diseased valve.
• The new valve is expanded (either by inflating a small balloon or by a self-expanding mechanism), pushing the old, stiff valve leaflets aside.
• Immediately, the new valve begins working, and blood flows freely.
• The catheter is withdrawn, and the puncture site is closed.

The whole procedure usually takes between 60 and 90 minutes.

3. The Replacement Valve Itself

The new valve is made from biological tissue (usually from a cow or pig) attached to a metal stent frame. Once expanded inside your heart, it functions just like a healthy natural valve — opening and closing silently with every heartbeat.

Who Is TAVI Suitable For?

TAVI was originally developed for patients who were considered too high-risk for open-heart surgery — for example, older adults, those with other serious health conditions such as kidney disease, lung disease, or frailty, or people who had already had previous heart surgery.

Over the years, as evidence has grown, TAVI is now also offered to patients at intermediate and even low surgical risk, depending on their individual anatomy and circumstances.

A person who might benefit from TAVI includes:

• Older adults (typically 70+) with severe symptomatic aortic stenosis
• Patients who have been told they are not fit for open-heart surgery
• Those who want to avoid the longer recovery that comes with open surgery
• Individuals with other medical conditions that make a major operation risky

The decision is always made by a Heart Team — a group of specialists who review each patient's case carefully and recommend the approach that is most appropriate for that individual. No two hearts are the same, and the choice of procedure is always personalised.

What Are the Advantages of TAVI Over Open Surgery?

For the right patient, the TAVI procedure for aortic valve disease offers several important benefits:

• No open-chest incision — the breastbone is not cut
• Shorter hospital stay — often 2–4 days compared to a week or more after open surgery
• Faster recovery — many patients feel significantly better within a few weeks
• Lower risk of complications for high-risk surgical patients
• Performed under sedation in many cases, reducing anaesthetic burden
• Suitable for patients previously turned down for surgery

For a 78-year-old with breathlessness, for example, the ability to go home within a few days and gradually resume daily activities — walking in the park, spending time with grandchildren — can be life-changing.

What to Expect After TAVI

In the Hospital

After the procedure, you will be monitored closely in a cardiac care unit for at least 24 hours. The care team will watch your heart rhythm, blood pressure, and the puncture site. Most patients are moved to a regular ward within a day and are ready to go home in 2–4 days.

At Home — the First Few Weeks

• Rest is important, but light activity such as short walks is encouraged from the first day home.
• You will be asked to avoid lifting heavy weights for a few weeks to allow the puncture site to heal fully.
• Most patients notice an improvement in breathlessness and energy levels quite quickly.
• You will be prescribed blood-thinning medication (usually aspirin and sometimes an additional antiplatelet or anticoagulant) to protect the new valve in the early period.

Follow-Up

Regular follow-up appointments — including repeat echocardiograms — will be scheduled to check that the new valve is working well. This ongoing monitoring is an important part of your care, and our team in Rajkot coordinates this to make it as convenient as possible for patients.

Are There Any Risks?

Like any heart procedure, TAVI carries some risks, and your doctor will discuss these with you openly before you consent. Possible complications include:

• Stroke — a small but important risk; the team takes steps to minimise this
• Pacemaker requirement — a minority of patients need a permanent pacemaker after TAVI because the procedure can occasionally affect the heart's electrical pathway
• Vascular complications at the access site (groin)
• Valve leakage around the new valve (paravalvular leak)
• Kidney injury from the contrast dye used during imaging

It is worth knowing that in properly selected patients, the overall benefit of TAVI far outweighs these risks — this is why the Heart Team assessment is so thorough before any procedure is recommended.

TAVI in Rajkot and Gujarat — Closer to Home

Until recently, many patients in Gujarat had to travel to large metro cities for advanced valve procedures. Today, interventional cardiology centres in Rajkot are equipped with the technology and expertise to offer TAVI closer to home, reducing the stress of travel for patients and their families.

If you or a loved one has been diagnosed with aortic stenosis or told that a valve needs attention, an initial consultation with a cardiologist can help you understand whether TAVI or another approach is the right path forward.

Key Takeaways

• Aortic stenosis is a narrowing of the heart's aortic valve that worsens over time and needs treatment when it becomes severe.
• TAVI replaces the diseased valve through a small catheter in the groin — no open-chest surgery needed.
• The procedure takes about 60–90 minutes, and most patients go home within 2–4 days.
• TAVI is suitable for high, intermediate, and in selected cases low surgical-risk patients — decided by a Heart Team.
• Recovery is faster than after open surgery, and most patients notice a meaningful improvement in their symptoms.
• Regular follow-up is essential to ensure the new valve continues to work well.
