At a glance
Transcatheter Aortic Valve Implantation (TAVI) is a procedure that replaces a diseased aortic valve (the valve between the heart and the body's main artery) without open-chest surgery, using a thin flexible tube called a catheter to deliver a new valve directly into the heart.
In a healthy heart, the aortic valve opens and closes with every heartbeat to keep blood flowing in one direction. When the valve stiffens or narrows, a condition called aortic stenosis (narrowing of the aortic valve), the heart has to work much harder and blood flow to the rest of the body drops. During TAVI, a collapsible replacement valve made of biological tissue is crimped onto a small metal frame, guided through a blood vessel (usually in the groin), and expanded inside the old valve, which is pushed aside. The new valve takes over immediately.
Medical Condition
TAVI is most often used for patients with severe aortic stenosis who are considered too high-risk or not suitable for traditional open-heart surgery. Over time, its use has expanded to include a wider range of patients depending on their overall health, age, and anatomy.
- Severe aortic stenosis causing symptoms such as chest pain, fainting, or breathlessness on exertion
- Patients at high or extreme surgical risk due to advanced age, frailty, or multiple other serious illnesses
- Patients at intermediate surgical risk where the heart team decides TAVI is the better option
- A previously implanted surgical aortic valve that has worn out over time (a situation called valve-in-valve TAVI)
- Certain cases where open-heart surgery is not possible because of prior chest radiation, severe lung disease, or severely scarred chest tissue
TAVI is generally not chosen when the aortic valve anatomy does not suit the available devices, when the blood vessels used to guide the catheter are too narrow or heavily calcified (hardened by calcium deposits), or when another heart problem requires open surgery at the same time. Patients who would do equally well or better with conventional surgery, especially younger patients with few other health problems, are usually offered surgery instead.
Risks & Complications
TAVI carries real risks, and the level of risk differs significantly from one patient to the next depending on age, heart function, and other medical conditions.
- Stroke or mini-stroke (TIA, a brief interruption of blood flow to the brain), which can occur when small particles dislodge during the procedure
- Paravalvular leak, meaning a small gap between the new valve and the surrounding tissue that allows blood to flow backwards
- Heart block (disruption of the electrical signals that control the heartbeat), sometimes requiring a permanent pacemaker
- Vascular complications such as bleeding, bruising, or damage to the blood vessel at the access site, most often the groin
- Acute kidney injury (sudden drop in kidney function) due to dye used during imaging
- Irregular heart rhythms (arrhythmias) during or after the procedure
- In rare cases, the new valve can shift out of position during or shortly after implantation
- Infection of the new valve (endocarditis), which is uncommon but serious
- Death, which remains a possibility, especially in patients who are already very unwell
Preparation & Procedure
Before TAVI, the medical team carries out a detailed assessment over several days or weeks to plan the procedure precisely. This workup includes scans, blood tests, and consultations with cardiologists (heart specialists) and cardiac surgeons.
Patients are usually asked to stop eating and drinking for at least six hours before the procedure. Blood thinners and certain other medications may be paused in the days leading up to it, based on the prescribing doctor's instructions. Smoking and alcohol should be avoided in the weeks before, as both affect healing and anaesthesia.
The standard pre-procedure tests usually include a CT scan of the heart and aorta to measure the valve and plan the access route, an echocardiogram (ultrasound of the heart) to assess valve severity, blood tests including kidney function and clotting, and a coronary angiogram (an X-ray of the heart's own arteries) in many cases.
- The patient arrives at hospital and is prepared: an intravenous (IV) line is placed, and monitoring electrodes are attached to the chest.
- Anaesthesia is given. This is most often deep sedation or general anaesthesia, depending on the patient and the team's preference.
- A small incision is made, usually in the groin, to access the femoral artery (the large artery running through the upper leg).
- The catheter carrying the folded replacement valve is guided up through the artery toward the heart, with the team watching on X-ray screens.
- A temporary pacing wire is placed in the heart to control the heartbeat at key moments during valve deployment.
- The catheter is positioned inside the old, diseased valve.
- The new valve is expanded, either by inflating a balloon inside it or by the valve's own self-expanding frame, locking it into place.
- The team checks that the new valve is working correctly using imaging before removing the catheter.
- The access site is closed, and the patient is moved to a monitored recovery area or intensive care unit (ICU).
Aftercare
Most TAVI patients spend at least one or two nights in hospital after the procedure, sometimes longer if there are complications or the patient needs extra monitoring. Recovery is generally faster than after open-heart surgery, but it is not without restrictions.
- The groin access site is kept clean and dry, and any signs of bleeding, swelling, or warmth should be reported to the care team immediately.
- Blood thinners are prescribed for a period after TAVI to reduce the risk of clots forming on the new valve. The type and duration depend on the patient's other conditions.
- Heavy lifting and strenuous physical activity are restricted for several weeks. Walking is usually encouraged early to prevent blood clots in the legs.
- Driving is typically not allowed for a period decided by the cardiologist, partly because of the access site and partly because of the anaesthesia used.
- A follow-up echocardiogram is usually done within a few weeks after discharge to check how the new valve is functioning.
- Regular dental check-ups become especially relevant after TAVI because mouth bacteria can travel to the heart and infect the new valve. Dentists need to know about the implanted valve before any procedure.
- Cardiac rehabilitation (a supervised exercise and education programme) is offered in many centres to help patients regain strength and confidence.
- Patients who received a permanent pacemaker will need separate follow-up appointments to check its function.
- Symptoms to watch for at home include new shortness of breath, dizziness, fainting, fever, or any unusual swelling, all of which warrant prompt medical attention.
Cost & What Determines It
TAVI is one of the most expensive cardiac procedures available, and the total cost varies widely depending on where it is done, the patient's complexity, and the choices made about devices and hospital stay. A patient with a straightforward anatomy and no complications will face a very different bill from one who needs extra procedures or a longer stay.
- Complexity of the case: heavily calcified valves, unusual anatomy, or the need for a valve-in-valve procedure all add to the technical difficulty and resource use
- The transcatheter heart valve itself: these are sophisticated biological devices, and the valve model chosen significantly affects the overall cost
- Hospital class and country: a tertiary cardiac centre in Western Europe, the United States, or Singapore operates at a different price level than centres in Thailand, India, or Malaysia
- Type of anaesthesia and the expertise of the multidisciplinary heart team involved
- Length of hospital stay, including any time in the ICU after the procedure
- Whether a permanent pacemaker is needed and implanted during the same admission
- Imaging done specifically for planning, such as the CT angiogram of the aorta
- Post-procedure medications, particularly blood thinners that may need to be continued for months
- Rehabilitation services and follow-up consultations after discharge
Hospital packages for TAVI typically cover the procedure itself, the valve device, the catheterisation laboratory (cath lab) fee, anaesthesia, and a set number of nights in hospital. What is usually billed separately includes pre-admission tests done as an outpatient, any additional procedures performed at the same time, medications taken home at discharge, and all follow-up visits or scans after leaving hospital.
Indonesian patients should be aware that BPJS Kesehatan and most Indonesian private insurance policies do not cover medical treatment received abroad. Most patients travelling for TAVI pay out of pocket or through an international private health insurance plan that explicitly covers treatment overseas. Before travelling, ask the hospital for a detailed written cost estimate that breaks down every fee. This estimate helps avoid unexpected charges on arrival and gives a clear basis for comparing options across different destinations.
Frequently Asked Questions
How many sessions does TAVI take?
TAVI is a single procedure, not a course of treatment. The implantation itself usually takes one to three hours, and most patients then spend several days in hospital for monitoring before going home.
What does TAVI feel like, and will it be painful?
Most patients feel little or nothing during the procedure because it is performed under sedation or general anaesthesia, meaning you are either deeply relaxed or fully asleep. Afterwards, there is usually some soreness around the small entry site in the groin or chest where the catheter (a thin, flexible tube) was inserted, but this is typically mild and managed with pain relief.
How soon will I feel better after TAVI?
Many patients notice an improvement in breathing and energy within a few weeks as the new valve begins working. Full recovery varies from person to person, and your heart team will guide you on gradually returning to daily activities, usually over several weeks.
How much does TAVI cost?
The cost depends on several factors specific to this procedure, including the type and brand of valve device used, the complexity of your case, the class of hospital, and the length of your stay. The most reliable way to get a real number is to request a written estimate directly from the hospital.
