Who Is Eligible for TAVI? The Complete 2026 Patient Guide
Not every aortic stenosis patient qualifies for TAVI — and not every TAVI-eligible patient knows it yet. This 2026 guide covers every eligibility criterion: age, anatomy, risk score, valve type, and conditions that exclude you.

You are likely eligible for TAVI (Transcatheter Aortic Valve Implantation) if you have severe aortic stenosis confirmed on echocardiogram, are experiencing symptoms, and your aortic anatomy is suitable on CT scan — regardless of age or surgical risk. By 2026, TAVI is approved for high, intermediate, and low-risk patients. The final eligibility decision is made by a multidisciplinary Heart Team after reviewing your specific imaging.
When a cardiologist tells you that you have aortic stenosis and mentions TAVI, the question that immediately follows is one of the most important you will ask: "Do I actually qualify?" It is not a simple yes or no. Eligibility for TAVI depends on the severity of your valve disease, the anatomy of your aorta and surrounding structures, your surgical risk profile, your symptom burden, and in some cases your age. This guide walks through every criterion — including the ones that make you a strong candidate and the ones that may require a different approach.
The Core Eligibility Requirement: Severe Aortic Stenosis
TAVI treats one specific condition: severe aortic stenosis. Before any other eligibility criterion is assessed, your cardiologist must confirm that your aortic valve disease has reached the threshold of severity that justifies intervention. This is established by transthoracic echocardiography (TTE) — an ultrasound of the heart — and confirmed against three key measurements.
| Echocardiographic Measurement | Mild AS | Moderate AS | Severe AS ✓ TAVI threshold |
|---|---|---|---|
| Aortic Valve Area (AVA) | >1.5 cm² | 1.0–1.5 cm² | <1.0 cm² |
| Mean Pressure Gradient | <20 mmHg | 20–40 mmHg | >40 mmHg |
| Peak Aortic Jet Velocity | <3.0 m/s | 3.0–4.0 m/s | >4.0 m/s |
Two of these three criteria in the severe range — particularly AVA below 1.0 cm² — places you firmly in the TAVI consideration zone, provided you are also symptomatic. The presence of symptoms (breathlessness, chest tightness, fainting, declining exercise tolerance) is critical: guidelines do not recommend TAVI for asymptomatic severe AS in most cases, because the procedural risk outweighs the benefit until symptoms emerge.
Important exception: Asymptomatic severe AS may still qualify for TAVI if left ventricular function is declining (EF below 50%), if very high gradients are present, or if the patient is undergoing another cardiac procedure. Your cardiologist will assess whether watchful waiting or intervention is appropriate.
Surgical Risk Score: The Criterion That Changed Everything
When TAVI was first introduced, it was reserved exclusively for patients considered too high-risk or inoperable for conventional open-heart valve surgery. That restriction has been systematically dismantled by clinical trial evidence. Today, TAVI is approved and guideline-endorsed for all three risk categories.
The STS (Society of Thoracic Surgeons) Predicted Risk of Mortality score is calculated by your cardiac team based on age, heart function, kidney function, lung disease, diabetes, previous cardiac surgery, and several other factors. EuroSCORE II is the equivalent tool used in Europe and widely used across India's international cardiac centres. A high score indicates that conventional open surgery carries elevated risk — making TAVI the safer path. But a low score today no longer disqualifies you: it simply means the choice between TAVI and surgery is a clinical preference discussion rather than a safety necessity.
Anatomical Eligibility: What the CT Scan Reveals
Even when the valve disease is severe and the risk score is clear, TAVI eligibility ultimately depends on anatomy. A dedicated CT scan of the aortic root, aorta, and peripheral vasculature is essential for every TAVI candidate — and it is this scan that determines whether the procedure can be done safely, and if so, which valve size and access route to use.
Anatomical factors assessed on CT:

Age and TAVI: Is There an Upper or Lower Limit?
This is one of the most frequently asked questions from patients and families. The straightforward answer is that there is no fixed age limit for TAVI — the oldest patients successfully treated in clinical practice are well into their 90s. Age is considered as one component of frailty assessment, not as a barrier.
TAVI was originally designed for elderly patients who were too frail for open surgery, and it remains highly appropriate for patients in their 70s, 80s, and beyond. The relevant clinical question is not "how old are you?" but rather "what is your overall frailty and functional status?" Two patients aged 82 may have very different TAVI candidacy depending on their baseline function, comorbidities, and cognitive health.
Age and valve choice: a genuine clinical conversation
For younger patients — typically those under 65 — the choice between TAVI and surgical aortic valve replacement (SAVR) involves a durability discussion. Surgical bioprosthetic valves have a well-established 15–20 year track record. TAVI valve durability data is maturing rapidly, and the newest valve generations show excellent 10-year outcomes — but the long-term data beyond 15 years is still accumulating. For a 55-year-old patient, this distinction matters. For a 78-year-old, it rarely does. Your Heart Team will guide this discussion based on your specific life expectancy and preference.
Special Eligibility Scenarios: Who Else Qualifies?
The eligibility profile for TAVI has expanded dramatically since its introduction. Several patient populations that were not originally considered now have clear evidence-based pathways to TAVI.
Patients who received a surgical bioprosthetic aortic valve years ago, and whose valve has now degenerated (structural valve deterioration), are strong TAVI candidates. A new transcatheter valve can be deployed inside the failed surgical valve — avoiding a second sternotomy entirely. This "valve-in-valve" technique is now a well-established indication and is performed routinely at India's top structural heart programmes.
Patients who have had a previous CABG (bypass surgery) or other cardiac operation develop scar tissue (adhesions) in the chest cavity that makes repeat surgery significantly more dangerous. For these patients, TAVI is often the preferred treatment even at low surgical risk because it avoids reopening a previously operated chest entirely. This is one of the clearest and most compelling TAVI indications. For reference on bypass surgery and its relationship to later valve procedures, see our heart bypass surgery guide.
Having blocked coronary arteries does not disqualify you from TAVI. In many cases, angioplasty (stenting) of significant coronary lesions is performed before or alongside the TAVI procedure. This staged or combined approach is standard at India's high-volume centres. Understanding how TAVI differs from coronary procedures is important — see our full TAVI vs angioplasty vs bypass comparison.
Chronic kidney disease, COPD, obesity, previous stroke, atrial fibrillation, frailty, liver disease — all of these conditions increase the risk of open-heart surgery and strengthen the case for TAVI. Each comorbidity is factored into the STS/EuroSCORE risk calculation, and collectively they define the patient population for whom TAVI was specifically designed. None of them is an automatic disqualifier.

Who Is NOT Eligible for TAVI? Absolute and Relative Contraindications
Understanding who qualifies for TAVI is only half the picture. Being clear about the contraindications — the factors that preclude TAVI — is equally important, and helps patients avoid pursuing a procedure that is genuinely not suitable for their situation.
| Contraindication Type | Condition | Why It Matters |
|---|---|---|
| Absolute | No severe aortic stenosis | TAVI only treats severe AS — mild/moderate disease does not justify the procedure |
| Active endocarditis (valve infection) | Placing a prosthetic valve into an infected field risks catastrophic prosthetic valve endocarditis | |
| Inadequate anatomy (annulus too small or too large for any available valve) | No available device fits safely — surgical valve replacement required | |
| Life expectancy <12 months from non-cardiac cause | Procedural risk outweighs unlikely survival benefit — palliative care is appropriate | |
| Relative | Severe peripheral arterial disease (inadequate femoral access) | May require alternative access route — still potentially feasible |
| Severe LV dysfunction (EF <20%) | Very low cardiac output increases procedural risk — requires careful Heart Team discussion | |
| Recent stroke (<3 months) | Anticoagulation requirements and neurological fragility increase risk — timing dependent | |
| Extreme frailty with multi-organ failure | TAVI may technically succeed but patient may not recover sufficient function to benefit — goals-of-care conversation essential |
The Heart Team Assessment: How Eligibility Is Formally Decided
TAVI eligibility is never determined by a single doctor. International guidelines — ESC, AHA/ACC — require that every TAVI patient be assessed by a multidisciplinary Heart Team (MDT) before the procedure is confirmed. This team typically includes:
All of India's leading TAVI centres — Fortis Escorts, Medanta, Apollo, Max, BLK-Max — conduct formal Heart Team meetings for every structural heart case. This is not a formality; it is the moment where clinical experience, imaging data, and patient preference converge into a recommendation.

The Bottom Line: How to Know If You Qualify
TAVI eligibility in 2026 is broader than most patients expect. If you have severe aortic stenosis and symptoms, are over 65, or have a prior cardiac surgery, frailty, or a condition that makes open surgery risky — the chances are high that TAVI is appropriate for you. The formal eligibility determination requires an echocardiogram and a CT scan, reviewed by a multidisciplinary Heart Team. That process begins with a single step: sending your existing reports for expert review.
India's leading TAVI centres offer the same eligibility assessment process as the world's best cardiac hospitals — with a 24-hour remote review available through GAF Healthcare before you commit to any travel or cost. The assessment costs nothing. The information it provides is everything.
