Severe aortic stenosis can quickly become life-threatening, restricting blood flow from your heart and causing breathlessness, chest pain, and fatigue. Without treatment, it carries a 50% mortality rate within two years
TAVI (Transcatheter Aortic Valve Implantation) offers a minimally invasive alternative to open-heart surgery, enabling valve replacement with lower risk and faster recovery. Backed by strong clinical evidence, TAVI is now widely adopted globally and increasingly available in India.
In this guide, you will understand what TAVI is, how it works, who it is for, its benefits, risks, and cost considerations, helping you make an informed treatment decision.
What Is TAVI Heart Valve Replacement Surgery?
TAVI (Transcatheter Aortic Valve Implantation) is a specialized cardiology procedure where a new artificial valve is delivered via a thin catheter.
Unlike surgery, where the diseased valve is cut out, TAVI works on the "valve-in-valve" principle, the new valve is expanded inside the old, diseased one, pushing the calcified leaflets aside to create a wide, clear path for blood flow.
Let's understand exactly how the procedure is planned and performed. This step-by-step breakdown will give you a clear picture of what to expect.
How TAVI Heart Valve Replacement Surgery Works (Step-by-Step)
TAVI is a carefully planned, image-guided procedure performed by a specialised heart team. From evaluation to valve deployment, each step is designed to ensure precision, safety, and immediate improvement in blood flow.
Here’s how the process typically works:
1. Pre-Procedure Evaluation
Before TAVI, your care team conducts detailed assessments to confirm suitability and minimise risks:
- Echocardiography: Evaluates valve structure and severity of aortic stenosis
- CT Scan: Maps your blood vessels and valve anatomy for accurate planning
- Cardiac Risk Assessment: Reviews overall health, age, and surgical risk factors
2. Catheter Insertion
The procedure is typically performed in a Hybrid Cath Lab. The procedure usually begins with a small incision in the groin. A thin, flexible catheter is inserted through the femoral artery, avoiding the need for open-chest surgery.
3. Navigation to the Heart
Using real-time imaging, the catheter is carefully guided through your blood vessels to reach the diseased aortic valve.
4. Valve Deployment
A compressed artificial valve (bioprosthetic valve) is positioned within the damaged valve. Once in place, it is expanded, pushing aside the old valve and anchoring securely.
5. Immediate Valve Function
The new valve starts working instantly, restoring normal blood flow and reducing symptoms almost immediately.
The procedure typically takes 1–2 hours, and depending on your condition, it can be performed under local or general anaesthesia, ensuring both safety and comfort during the intervention.
In 2026, the use of "Conscious Sedation" has largely replaced general anaesthesia for TAVI. This means the patient remains breathing on their own, avoids the need for a ventilator, and can often speak with the doctors during the procedure.
This "minimalist approach" is a major factor in the rapid recovery observed at Meitra Hospital.
Access Routes: Beyond the Groin
While the Transfemoral (groin) approach is used in 95% of cases due to its safety, Meitra’s advanced imaging allows for alternative routes if the leg arteries are blocked:
- Transcarotid: Through the artery in the neck.
- Transaxillary: Through the artery under the arm/shoulder.
- Transapical: Through a tiny incision between the ribs (rarely needed in 2026).
To ensure optimal outcomes, advanced imaging and meticulous pre-procedure planning play a critical role.
The Precision of TAVI-CT Planning at Meitra
The success of a TAVI procedure is determined long before the patient enters the Cath Lab. At Meitra Hospital, every patient undergoes a high-resolution 128-slice ECG-gated CT scan.
Here's why the CT Scan is Critical:
1. Annulus Sizing
If the valve is too small, it will leak (Paravalvular Leak); if too large, it can rupture the aortic root. Precision within 0.5mm is required.
2. Coronary Height
We must ensure the new valve frame does not block the openings of the coronary arteries, which supply blood to the heart muscle.
3. Calcification Mapping
The CT identifies where the heaviest calcium deposits are, helping the doctor decide how to expand the valve safely.
4. Vascular Access
It acts as a "GPS" for the leg arteries, ensuring the catheter can travel safely to the heart.
To choose the right treatment, it helps to understand how TAVI compares with conventional surgical options.
How TAVI Differs from Traditional Surgery (SAVR)
To understand why TAVI is often preferred in 2026, we must compare it to the traditional surgical approach (SAVR).
1. The Physical Trauma
SAVR requires a sternotomy, cutting the breastbone in half. This takes 2-3 months to heal. TAVI involves a needle puncture in the groin, which heals in 2-3 days.
2. The Heart-Lung Machine
In surgery, the heart is stopped, and blood is circulated by a machine. This can sometimes cause "pump head" (cognitive fog) or inflammatory responses in the elderly. TAVI is performed on a beating heart, maintaining natural blood flow throughout.
Here's a quick comparison among both:
| Feature | TAVI (Transcatheter) | SAVR (Traditional Surgery) |
|---|---|---|
| Anaesthesia | Local + Sedation | General Anaesthesia |
| Hospital Stay | 2–3 Days | 7–10 Days |
| ICU Requirement | <24 Hours | 2–4 Days |
| Back to Work/Life | 1–2 weeks | 8–12 Weeks |
| Risk of Stroke | <1.5% (with CEP) | 2–3% |
| Pacemaker Risk | 5–10% | 2–3% |
As you explore treatment options, understanding the real-world benefits of TAVI can help you make a more confident, informed decision.
Top Benefits of TAVI Heart Valve Replacement Surgery
TAVI has transformed the management of aortic stenosis by offering a less invasive yet highly effective alternative to open-heart surgery. It is especially valuable for patients seeking faster recovery with reduced procedural risk.
Here are the key advantages you should know:
1. Immediate Symptom Relief
Because the obstruction is removed instantly, patients often feel a "rush of energy" or immediate ease in breathing as soon as the valve is deployed. This is particularly striking in patients who were previously housebound due to severe fatigue.
2. Preservation of the "Native" Heart
By avoiding surgery, we preserve the pericardium (the sac around the heart). This is crucial if the patient needs any other heart interventions later in life, as it prevents the formation of tough scar tissue.
3. Lower Infection Rates
Without a large surgical wound, the risk of "Sternal Wound Infection" or "Mediastinitis" is virtually eliminated. This makes TAVI the gold standard for patients with Diabetes or Chronic Kidney Disease, whose immune systems may be compromised.
4. Psychological Wellbeing
The "fear of the knife" is a significant barrier to treatment. TAVI’s minimally invasive nature encourages patients to seek help earlier in the disease process, before the heart muscle suffers permanent damage.
As you evaluate your treatment options, understanding the cost and what influences it can help you plan better, especially if you are considering care in India.
Cost of TAVI Heart Valve Replacement Surgery in India
India has emerged as a global leader in TAVI due to a unique combination of high-volume expertise and cost-efficiency. In 2026, the price of TAVI in India generally ranges between INR 12 lakhs and INR 30 lakhs.
Here are the key factors that influence the overall cost:
Valve Choice
International valves (like the Edwards Sapien 3 or Medtronic Evolut) remain the premium choice. However, India-made valves like the Myval and Hydra (approved by the DCGI) have proven non-inferior in 2025-2026 clinical trials and are significantly more affordable.
CEP Integration
The use of Cerebral Embolic Protection (filters that catch debris to prevent stroke) adds a small cost but is highly recommended for high-risk patients.
Length of Stay
Because Meitra utilizes a "Fast-Track" protocol, most patients save on hospital room charges compared to traditional surgery.
A TAVI procedure in the United States or UK typically costs between $40,000 and $60,000 (INR 33–50 lakhs). By choosing Meitra Hospital, international and domestic patients access the same technology for a fraction of the price.
