TAVR / TAVI
A new heart valve — without opening the chest
Also known as: TAVI · Transcatheter Aortic Valve Implantation · keyhole aortic valve replacement · aortic valve replacement without open surgery

What it is
Think of the aortic valve as the one-way exit door from your heart's main pumping chamber. Every heartbeat, it opens to let a jet of blood out to the body, then snaps shut so none leaks back. In aortic stenosis this door stiffens — usually from calcium building up over years — and can no longer open fully. Your heart is forced to push blood through a narrowing gap, working harder and harder until it begins to tire.
TAVR fixes that door without opening your chest. A replacement valve, folded down inside a tube thinner than a pen, is guided up from a small puncture in the groin to the heart. Positioned precisely inside your old, diseased valve, it is expanded open and immediately takes over the work — the old valve simply pinned aside behind it. Your heart never stops, and there is no surgical cut on the chest.
This matters because untreated severe aortic stenosis, once it causes symptoms, is genuinely dangerous. For decades the only fix was open-heart surgery, which ruled out many older or frailer patients. TAVR changed that — valve replacement is now within reach for almost everyone who needs it.
Your diagnosis rests on an echo — and when that report is in your hands, Heart Simplified explains what every line on it means ↗, in plain language.
Who it's for
- Severe aortic stenosis with breathlessness, chest pain, giddiness or blackouts
- Elderly patients or those at elevated surgical risk
- Failed surgical bioprosthetic valves (valve-in-valve TAVR)
- Patients preferring a minimally invasive option after heart-team review
Signs you might need it
- Breathlessness climbing stairs or walking uphill
- Chest tightness or pressure on exertion
- Dizziness, light-headedness, or fainting — especially during activity
- Unusual tiredness and loss of stamina
- A heart murmur your doctor can hear
- Some people feel nothing until the valve is very narrow — which is why an echocardiogram matters if a murmur is found
How we confirm you need it
- Echocardiography — the key test; measures exactly how narrow and how severe the valve is
- CT angiography — maps your valve, its exact size, and the groin arteries, so the right valve size and access route are chosen
- Coronary angiography — checks whether any heart arteries are also blocked
- ECG and blood tests to complete the picture
- Heart-team review — interventional cardiologist, cardiac surgeon and anaesthetist agree the safest plan for you
How it happens, step by step
1
Heart-team evaluation
Echocardiography and a CT scan map your valve and vessels. A heart team — interventional cardiologist, surgeon, anaesthetist — confirms TAVR is your best option and selects the valve size.
2
Access
Under sedation or light anaesthesia, the valve delivery system enters through a 5–6 mm puncture in the groin artery. No chest incision, no heart-lung machine.
3
Valve deployment
The new valve, mounted on a catheter, is positioned inside your old valve using X-ray and echo guidance, then expanded — taking over instantly.
4
Confirmation
Function is verified on the table. Many patients are awake enough to know the valve is working before leaving the lab.

The rigour behind it
How every TAVR I do is planned — so nothing is missed
A TAVR is only as good as its planning. Every case I perform runs through TAVI123 — a governance system I built specifically for structural heart procedures. From the first screening echo to the final follow-up, each patient's CT annulus measurements, access-vessel sizing, calcium assessment, risk scores and heart-team decision are captured in one structured pathway.
That means no measurement is forgotten, every device choice is documented with its reasoning, and your case is handled with exactly the same rigour as every other. Uniform, auditable data capture isn't paperwork — it is how a modern valve programme keeps patients safe.
The benefits
- No chest incision, no breastbone cut, no heart-lung machine
- Breathlessness often eases within days
- Short hospital stay and a quick return to normal life
- A real option for patients considered too high-risk or frail for open surgery
- Outcomes that match or exceed open surgery in appropriately selected patients
The risks
- Vascular access-site complications at the groin — most often bruising or bleeding, and less commonly an injury to the artery (a tear, blockage or a swelling called a pseudoaneurysm) that may need a stitch, a covered stent or a short repair
- Some patients need a permanent pacemaker, as the new valve sits near the heart's wiring
- A small risk of stroke
- A minor leak around the new valve (paravalvular leak) in some cases
- As with any procedure — contrast effects on the kidneys, and rare valve-related issues; the heart team weighs every risk against the benefit for you specifically
Alternatives we'll discuss
Surgical aortic valve replacement (SAVR)
The long-established open-heart operation. Still the best choice for some — often younger, lower-risk patients, or particular valve anatomies. The heart team will tell you when surgery serves you better.
Balloon aortic valvuloplasty
A balloon briefly stretches the valve open. It is not a lasting fix — mainly a temporary bridge in selected, unstable patients while a definitive plan is made.
Medicines alone
Can soften symptoms for a time but cannot reopen the valve. For severe symptomatic aortic stenosis, medication is not a substitute for replacing the valve.
Preparing for it
- Complete your scans (echo, CT, angiography) and blood tests
- Review medicines with your team — some blood thinners are adjusted beforehand
- Have a dental check-up if advised, to reduce any risk of valve infection
- Fast from midnight before the procedure as instructed
- Arrange for someone to bring you home and help for the first few days
Recovery
- Most patients sit up the same evening and walk the next day
- Typical discharge in 2–4 days
- Return to normal activity within 1–2 weeks for most
- Blood thinners and follow-up echocardiograms as advised
Results & durability
- Symptom relief is often rapid and marked — many patients notice easier breathing within days
- Valve durability in current data extends well beyond 8–10 years, with longer-term studies ongoing
- For most patients, the valve is expected to last a lifetime
- Lifelong follow-up with periodic echocardiograms keeps the valve under watch
Cost & insurance
What affects the cost
- The largest factor is the valve device itself; the hospital, room category, and any extra step such as a pacemaker also affect the total
- TAVR is covered by many private insurance policies and some government schemes — coverage varies by plan
- We help you understand what your specific policy covers before you commit to anything
- For a figure tailored to your case and cover, please book a consultation — printed prices online can mislead more than they help
Common questions
How long does a TAVR valve last?
Current data shows excellent durability beyond 8–10 years, with studies ongoing. For most patients receiving TAVR, the valve is expected to serve for their lifetime.
Am I too old for TAVR?
Age alone rarely rules out TAVR — it was designed for older patients. Suitability depends on anatomy and overall health, assessed by the heart team.
TAVR or open surgery — which is better for me?
For many patients, both are valid. We weigh age, anatomy, surgical risk and your priorities transparently — the heart-team model exists precisely for this decision.
Is TAVR painful?
There is no chest wound. Discomfort is limited to the small groin puncture, and most patients are surprised by how quickly they're back on their feet.
Will I need a pacemaker after TAVR?
Some patients do, because the new valve sits close to the heart's natural wiring and can affect it. Most patients do not. We monitor your rhythm closely for a few days afterwards.
How soon can I go home and get back to normal?
Many patients are discharged within 2–4 days and back to routine activity within one to two weeks. Your team will give you a personalised timeline.
My earlier surgical valve has failed — can TAVR still help?
Often yes. A TAVR valve can be placed inside a failed surgical bioprosthetic valve — called valve-in-valve TAVR — sparing many patients a repeat open operation.
Can medicines cure severe aortic stenosis instead?
No. Medicines can ease symptoms for a while, but they cannot reopen a stiffened valve. Once severe aortic stenosis causes symptoms, replacing the valve is the only definitive treatment.
