If you or someone in your family has just been told the aortic valve isn't working the way it should, the next few weeks can feel overwhelming. Doctors start using terms like "aortic stenosis," "TAVI," and "TAVR," and it's not always clear what any of it actually means for daily life, recovery, or what happens next. This article walks through what TAVI is, who it's meant for, how the procedure itself works, and what recovery typically looks like, written in plain language, for patients and families trying to understand their options before a consultation.
What TAVI Actually Treats
TAVI stands for Transcatheter Aortic Valve Implantation. It's also called TAVR (Transcatheter Aortic Valve Replacement), the two terms describe the same procedure, with TAVI more commonly used in Europe and Asia and TAVR more common in the US.
The procedure treats aortic stenosis, a condition where the aortic valve, the valve that controls blood flow out of the heart and into the rest of the body, becomes thickened, calcified, and stiff over time. As the valve narrows, the heart has to work harder to push blood through it. Left untreated, severe aortic stenosis can lead to chest pain, fainting, breathlessness, and eventually heart failure.
For decades, the only fix was open-heart surgery to replace the valve. TAVI changed that by offering a way to replace the valve without opening the chest at all.
How TAVI Is Different From Open-Heart Surgery
In traditional aortic valve replacement surgery, the surgeon opens the chest, stops the heart temporarily, and physically removes the damaged valve before sewing in a new one. It's effective, but it's a major operation, long hospital stay, general anesthesia, a real recovery period, and meaningful risk for older or frailer patients.
TAVI takes a different route entirely. Instead of removing the old valve, a new replacement valve, collapsed down to fit inside a thin catheter, is guided through a blood vessel (usually in the groin) up to the heart. Once it's positioned correctly inside the old, damaged valve, it's expanded. The new valve pushes the old valve's leaflets out of the way and takes over the job of controlling blood flow immediately.
No chest incision. No stopped heart. For the right patient, this difference is enormous, both in terms of risk and in how quickly they're back on their feet.
Who Is a Good Candidate for TAVI
TAVI isn't automatically the right choice for every aortic stenosis patient, it's most established for people who are at intermediate or high risk for standard open-heart valve surgery. That typically includes patients who are older, or who have one or more of the following:
- Cerebrovascular or peripheral arterial disease
- Chronic kidney disease
- Chronic respiratory dysfunction
- Frailty or reduced ability to tolerate a long surgical recovery
In recent years, the evidence base for TAVI has expanded well beyond just high-risk patients, and many cardiologists now consider it for intermediate-risk and select lower-risk patients too, depending on individual anatomy and overall health. This is exactly why a proper evaluation matters, age and risk factors are part of the picture, but valve anatomy, calcification pattern, and vascular access all influence whether TAVI is the right fit, and that can only be judged after imaging and assessment.
What Happens During the Procedure
A TAVI procedure generally follows this sequence:
- Pre-procedure assessment. Before anything happens in the cath lab, the team reviews detailed imaging, usually a CT scan of the heart and blood vessels, to plan valve size, access route, and positioning. This planning stage is a big part of why outcomes have improved so much over the years.
- Anesthesia. Depending on the case, this may be local anesthesia with sedation or general anesthesia.
- Access. A catheter is inserted, most commonly through the femoral artery in the groin. In cases where femoral access isn't suitable, alternative routes are used.
- Valve delivery and positioning. The collapsed replacement valve is threaded up through the blood vessels to the site of the old aortic valve, guided by live imaging.
- Deployment. The new valve is expanded into place, immediately taking over the work of regulating blood flow.
- Monitoring. The team checks that the new valve is functioning correctly, confirming there's no significant leakage around the valve (paravalvular leak) and that the heart's electrical conduction hasn't been disrupted, before closing the access site.
The entire procedure typically takes one to two hours, though this varies by case complexity.
A Real Case: When Anatomy Gets Complicated
Not every TAVI case is straightforward, and this is where individualized planning matters most. In one recent case, a 79-year-old woman presented with a moderately calcified tricuspid aortic valve and low-lying coronary arteries, a combination that raises the risk of the new valve interfering with blood flow to the coronary arteries if positioning isn't precise.
The team used an Accurate neo2 valve, chosen specifically for its self-expanding design and supra-annular leaflet position, which reduces the risk of coronary obstruction in anatomically tricky cases like this one. Following the procedural plan, the outcome was clean: a single pressure gradient across the new valve, no paravalvular leak, and no conduction disturbance requiring a pacemaker.
This is the kind of detail that matters when researching where to have TAVI done, not just whether a center performs the procedure, but whether the team has experience handling the anatomical curveballs that don't show up in textbook cases.
What Recovery Looks Like
This is one of the biggest practical differences from open-heart surgery, and usually what patients and families want to know first.
Hospital stay. Many TAVI patients are discharged within 2 to 5 days, compared to a week or more after open-heart valve surgery. Some straightforward cases go home even sooner.
Immediate recovery. Because there's no chest incision, patients are typically up and walking within a day. There's no sternum healing to manage, which is often the slowest part of recovering from open-heart surgery.
First few weeks. Most patients notice an improvement in breathlessness, fatigue, and exercise tolerance fairly quickly, since the valve starts working properly the moment it's deployed. Activity is usually built back up gradually over a few weeks, following the care team's guidance.
Longer term. Current-generation TAVI valves are generally expected to last many years, though exact durability depends on valve type and the patient's individual profile. Regular follow-up with echocardiograms is part of standard long-term care to confirm the valve continues to function well.
What to watch for. Any new or worsening breathlessness, dizziness, irregular heartbeat, or swelling after discharge should be reported to the cardiology team promptly, these are uncommon but worth not ignoring.
Why Where You Have It Done Matters
TAVI is a technically demanding procedure that depends heavily on imaging quality, the experience of the team reading that imaging, and the infrastructure available if something doesn't go exactly to plan. In Delhi, TAVI is performed at a small number of centers equipped with the hybrid cath labs, advanced CT planning, and electrophysiology backup needed to manage both routine and anatomically complex cases.
Dr. Viveka Kumar, Chairman of Cardiology at Max Super Speciality Hospital, Saket, has been performing structural heart interventions including TAVI for several years, alongside a broader practice of complex coronary and electrophysiology procedures. Cases like the Acurate neo2 implant above reflect the kind of detailed, anatomy-specific planning that goes into each TAVI procedure at the center.
What TAVI Typically Costs in Delhi
TAVI costs in Delhi vary depending on the valve type used, hospital, room category, and whether there are any additional complexities in the case. Costs in India remain considerably lower than in the US, UK, or Europe, which is part of why Delhi sees a steady number of patients traveling from other states and countries specifically for this procedure.

Questions Worth Asking Before Choosing a TAVI Specialist
If you're at the stage of choosing where to have this done, a few questions tend to matter more than general reputation:
- How many TAVI procedures has the team performed, and how many different valve types are they experienced with?
- Is there a structural heart and electrophysiology team available in case a pacemaker is needed after the procedure?
- What imaging and planning process is used before the procedure, and will you get a chance to discuss your specific anatomy and risk factors directly?
- What does the hospital's hybrid cath lab and post-procedure monitoring setup look like?
A good specialist will walk you through these answers without being asked twice.
Getting Evaluated
If you or a family member has been diagnosed with aortic stenosis and you're trying to figure out whether TAVI is the right path, the first step is a proper evaluation, imaging, a review of overall health and risk factors, and a real conversation about options.
