Every year, thousands of patients in India and around the world are diagnosed with severe aortic stenosis. It progressively restricts blood flow from the heart and, if left untreated, can be fatal.
For decades, open-heart surgery was the only definitive treatment. For elderly or high-risk patients, that option was often too dangerous to consider.
Transcatheter Aortic Valve Implantation (TAVI) in cardiology has changed that.
Transcatheter Aortic Valve Implantation (TAVI) is one of the biggest breakthroughs in modern cardiac care. It offers a minimally invasive alternative to open-heart surgery for patients who need aortic valve replacement, and its adoption across India is growing rapidly.
This guide covers everything you need to know:
How the procedure works, who it is suitable for, what the risks are, and what to expect during recovery.
TAVI stands for Transcatheter Aortic Valve Implantation, a procedure also commonly referred to as Transcatheter Aortic Valve Replacement (TAVR). It is a minimally invasive procedure that replaces a diseased aortic valve without opening the chest (median sternotomy).
TAVR is primarily used to treat severe aortic stenosis. This is a condition where the aortic valve becomes stiff, calcified, and unable to open fully. When this happens:
TAVI solves this by delivering a brand new, fully functional valve to the heart through a thin tube called a catheter. No open-chest surgery needed. The new valve is placed inside the existing diseased valve and starts working immediately.
Before TAVI, the only treatment for severe aortic stenosis was open-heart surgery or Surgical Aortic Valve Replacement (SAVR). It works, but it comes with significant demands:
For many patients, particularly those aged 75 and older or those managing conditions like kidney disease, lung disease, or diabetes, these risks were simply too high. Many were told surgery was not an option and were left without any curative treatment.
TAVI was developed specifically for these patients. By replacing the valve through a catheter, it dramatically reduces physical trauma and makes treatment accessible to those who need it most.
The procedure is carried out by an interventional cardiologist, usually working alongside a cardiac surgeon. Here is what happens, step by step:
There are two main valve types used in TAVI:
Indian-manufactured valve platforms are also now available. These have significantly reduced the cost of TAVI in India without compromising on quality or outcomes.
Candidacy is determined by a multidisciplinary heart team, including a cardiologist, cardiac surgeon, imaging specialist, and anaesthetist. TAVR is most suitable for:
TAVI may not be suitable for patients with:
TAVI and open-heart surgery both address severe aortic stenosis, but differ significantly in approach, invasiveness, and patient suitability.
| Factor | TAVI | Open-Heart Surgery (SAVR) |
| Procedure Type | Minimally invasive, catheter-based | Traditional open-chest surgery |
| Anesthesia | Conscious sedation | General anesthesia |
| Incision | Small incision in groin or chest | Large incision through breastbone |
| Heart Stopped? | No | Yes, bypass machine used |
| Hospital Stay | 1-2 days | 5-10 days |
| Recovery Time | 1-2 weeks | 6-8 weeks or longer |
| Ideal Candidates | Elderly or high-risk patients | Younger or low-risk patients |
| Valve Durability | 10-15 years | Generally longer |
| Stroke Risk | Less than 1% | Higher than TAVI |
| Pacemaker Requirement | 1-5% of cases | Rare |
Like all cardiac procedures, TAVI carries some risk. Here is what patients should be aware of:
Recovery after TAVI is one of its biggest advantages over open-heart surgery. Here is what most patients can expect:
Because the chest is never opened and the heart is never stopped, physical discomfort is significantly lower than after open-heart surgery. Most patients are genuinely surprised by how quickly they feel like themselves again.
TAVI cardiology has genuinely changed the landscape of heart valve treatment. It has given thousands of patients, many of whom had no other option, a safe, effective, and fast-recovery path to a healthier heart.
If you or a loved one has been diagnosed with severe aortic stenosis and would like to know whether TAVI is the right option, the specialist team at Heart Valve Experts is here to help. We offer personalised consultations with honesty, expertise, and genuine care for the life ahead.
TAVI stands for Transcatheter Aortic Valve Implantation. It is a minimally invasive procedure used to replace a narrowed aortic valve without open-heart surgery.
Yes. Both refer to the same procedure. TAVI is the term used in India, Europe, and the UK. TAVR is more common in the United States.
Patients with severe symptomatic aortic stenosis who are at intermediate or high surgical risk. It is also now approved for low-risk patients in many countries.
Typically one to two hours. Most patients are discharged within one to two days.
Yes. The valve is a permanent replacement lasting 10 to 15 years or more. If it deteriorates, a second TAVI (valve-in-valve) can be performed.
No. It is performed under sedation. Post-procedure discomfort is generally mild, as there is no large incision involved.
Very. Clinical trials and real-world data confirm outcomes comparable to or superior to open-heart surgery across intermediate and high-risk patient groups.
No strict age limit. TAVI is routinely performed in patients in their 80s and 90s. Candidacy is based on overall health and anatomy, not age alone.
Yes. A second procedure called valve-in-valve TAVI can be performed if the original valve deteriorates over time.
