TAVR: Replacing an Aortic Valve Without Open-Heart Surgery
What it is, who it suits, and what the week afterwards really looks like.
Aortic stenosis is one of the few serious heart conditions that people routinely mistake for getting old. It comes on slowly, over years, and the symptoms are exactly the ones we all expect to develop eventually: you get out of breath on the stairs, you tire more easily, you stop doing one or two things you used to do.
Very often it is not age. It is a valve.
What aortic stenosis is
The aortic valve is the door between the heart's main pumping chamber and the rest of the body. Every heartbeat, it opens to let blood out and closes to stop it coming back.
With age, calcium builds up on the valve. The leaflets stiffen, and the opening gets smaller. The heart has to push harder and harder through a shrinking gap, and eventually the muscle thickens from the effort and starts to struggle.
It is common. It becomes much more common past 70, and in communities like North Fort Myers and Punta Gorda, where a large share of residents are over 65, it is something we look for routinely.
The first clue is often a murmur, heard through a stethoscope at a routine visit. An echocardiogram, an ultrasound of the heart, confirms it and shows how tight the valve has become.
The three symptoms that matter
Once a narrowed aortic valve starts causing symptoms, the outlook changes significantly. So these three are worth knowing:
Breathlessness on exertion, or lying flat, that is new or getting worse.
Chest tightness or pressure when you exert yourself, easing when you stop.
Dizziness, light-headedness or fainting, particularly during activity.
People explain all three away. The breathlessness is the heat, the tightness is indigestion, the dizziness is standing up too fast. Sometimes that is true. But if you have a known murmur or valve problem and any of these has changed, it needs looking at now rather than at the next annual review.
What TAVR is
TAVR stands for transcatheter aortic valve replacement. A replacement valve, made from tissue and mounted inside a collapsible frame, is compressed down small enough to fit inside a catheter. The catheter goes in through an artery, almost always at the top of the leg, and is guided up to the heart. The new valve is positioned inside the old one and expanded. It pushes the old leaflets aside and takes over the job immediately.
The chest is never opened. The heart is not stopped, and there is no heart-lung bypass machine.
It began as an option only for people too frail for surgery. It is now an established treatment across the risk spectrum, and in the United States it is performed more often than surgical valve replacement.
TAVR or open-heart surgery?
Both work. The honest answer is that the right choice depends heavily on your age, because it comes down to how long the valve has to last.
A TAVR valve is made of tissue, and tissue valves wear out eventually. In someone of 85 that is rarely the deciding issue. In someone of 58 it very much is.
National guidance sets it out roughly like this:
Under 65, with a long life expectancy, surgery is generally favored. Mechanical valves last far longer, and a younger patient has more years for a tissue valve to fail in.
Between 65 and 80, either approach is reasonable, and the decision is made individually. This is where the conversation matters most.
Over 80, or where life expectancy is under ten years, the catheter approach is generally favored, at any level of surgical risk.
Anatomy matters too. Not every valve or every set of leg arteries suits a catheter approach, and that is something imaging shows before any decision is made.
This decision is meant to be made by a heart team — a structural cardiologist and a cardiac surgeon together, with you in the room — rather than by whichever specialist you happened to be referred to. If that has not happened, ask for it.
A recent change worth knowing about
For decades the rule was simple: if a narrowed valve was not causing symptoms, you waited and watched.
That has shifted. A trial called EARLY TAVR, reported in 2024, compared treating severe aortic stenosis early against watchful waiting in patients who had no symptoms, and found that early treatment reduced the combined risk of death, stroke and unplanned hospital admission. In May 2025 the FDA approved the use of certain valves specifically in patients with severe aortic stenosis who have no symptoms.
This does not mean everybody with a narrowed valve should have it replaced tomorrow. It does mean that "you have no symptoms, come back in a year" is no longer automatically the right answer, and that severe aortic stenosis is now worth a proper discussion even when you feel completely well.
If you have been told you have severe aortic stenosis and are being watched, this is a reasonable thing to raise, or to seek a second opinion about.
What the day looks like
Before
There is more preparation for TAVR than for most heart procedures, and it is worth it. A CT scan measures your valve and your arteries precisely, so the right size of valve is chosen and the route in is planned. An echocardiogram, blood tests and often a coronary angiogram come first as well. Some people have a coronary narrowing treated with a stent beforehand.
Bring a full list of everything you take. Some medicines are paused, and you will be told exactly when to stop eating.
The procedure
Most people have sedation rather than a full general anesthetic, which is one of the reasons recovery is quicker. A small puncture or incision is made at the top of the leg, the catheter is guided up under X-ray, and the new valve is positioned and expanded.
It usually takes one to two hours. You may be aware of activity around you and remember little of it.
Afterwards
You go to a monitored area, and your heart rhythm is watched closely. The main reason for that is that the new valve sits very close to the heart's own electrical wiring, and in a minority of people that wiring is disturbed enough to need a permanent pacemaker.
Many people are up and walking the same day. A hospital stay of one to two days is common after a straightforward procedure, and some people go home the day after. Compare that with a week or more, and a breastbone that takes months to heal, after open surgery.
Recovery, realistically
The first few days: keep the groin site clean and dry. Bruising is normal. Expect to feel tired, and expect that to surprise you given how small the wound is.
Walking starts straight away and is the main thing you should be doing. Little and often.
Lifting: nothing heavy for the first week or two.
Driving: usually around a week, but confirm it with us for your case.
The breathlessness often improves quickly, sometimes within days, because the obstruction is gone the moment the valve is in. People frequently describe noticing it on the walk to the car.
Cardiac rehabilitation: take it if it is offered. It is one of the better-evidenced things you can do afterwards.
Follow-up: an echocardiogram to check the new valve, then regular reviews for as long as you have it.
The risks, plainly
TAVR is well established and most people do well
These are the things worth knowing about before the day.
Needing a permanent pacemaker
Because of that electrical wiring next to the valve. This is the most common significant complication, and the risk varies with your own anatomy and which valve is used. Ask for your figure.
Stroke
Uncommon, but the one people most want to know about, and you should ask about it directly.
Bleeding or damage to the artery in the leg
Where the catheter went in.
A small leak around the new valve
Usually minor and well tolerated; occasionally it needs attention.
Kidney effects from the contrast dye
Particularly if your kidneys are already impaired.
Valve durability
Tissue valves do not last forever. This is the central consideration for younger patients and a minor one for the very elderly.
FAQs
Common Questions
Am I too old for this?
Almost certainly not. Age on its own is not what decides it, and for patients over 80 the catheter approach is the favored option rather than the fallback. Frailty, other conditions and what you want out of the next few years matter far more than the number.
How long will the new valve last?
Long-term data continue to accumulate, and for most older patients the valve is expected to outlast the need for it. For younger patients it is the main reason surgery may be the better choice, and it is a conversation to have properly rather than a detail to skim.
Can it be replaced again later if it wears out?
In many cases a second valve can be placed inside the first. Whether that is possible for you depends on your anatomy and on which valve was used first, which is part of why the first decision is planned so carefully.
Will I need blood thinners afterwards?
You will be on medication afterwards, and what exactly depends on your rhythm and your other conditions. Do not stop anything without asking us first.
What if I do nothing?
For severe aortic stenosis that is causing symptoms, doing nothing has a poor outlook, and that is worth saying plainly. Medication does not fix a narrowed valve; it can only manage around it. If you are weighing this up, ask for the specifics of your own situation rather than a general answer.
Is it covered by Medicare?
TAVR is an established, covered procedure for appropriate patients. Coverage depends on your plan and on meeting the clinical criteria, and our office will go through it with you before anything is scheduled.
Can I get a second opinion?
Yes, and you should not feel awkward asking. Bring your echocardiogram and CT images if you have them. Actual images are far more useful than a report describing them.
The short version
Aortic stenosis is a narrowed valve that gets mistaken for ageing. The three symptoms that matter are breathlessness, chest tightness on exertion, and dizziness or fainting. TAVR replaces the valve through a catheter in the leg rather than by opening the chest, usually in one to two hours, with many people home within a day or two. Under 65 surgery is generally favored, over 80 the catheter approach is, and in between it is a genuine decision to make with a heart team. And since 2025, severe aortic stenosis without symptoms is no longer automatically a matter of waiting and watching.
