Transcatheter Mitral Valve Replacement (TMVR): Procedure, Risks and Recovery

Written and medically reviewed by Dr. Baraa Alnahhal, MD · Last reviewed: October 2026 · How we review

Quick Answer: What is TMVR?

Transcatheter mitral valve replacement (TMVR) is a procedure that replaces a faulty mitral valve with a new valve delivered through a thin catheter, usually through an incision in the groin or chest. It treats mitral valve regurgitation or stenosis in people who are not good candidates for open-heart surgery, and usually takes two to three hours. [1]

What the research says

• TMVR places the valve successfully in most patients. A systematic review of 16 publications covering 308 high-risk patients with severe mitral regurgitation found technical success in 91.7% of cases and residual moderate-to-severe leakage in only 1.5%, although all-cause 30-day mortality was 13.6% in this very sick group. (Del Val et al., J Am Heart Assoc, 2019) [7]

• For a failed earlier mitral valve, TMVR carried fewer in-hospital problems than redo surgery. In a meta-analysis of 9 studies and 3,038 patients, TMVR was linked to lower in-hospital mortality (odds ratio 0.44) and less stroke (odds ratio 0.44) than repeat open surgery, with no difference in 1-year mortality; paravalvular leak was more common after TMVR. (Zhou et al., Front Cardiovasc Med, 2023) [8]

• Stroke around the time of TMVR is uncommon. Pooling 26 studies with 1,910 TMVR patients, the estimated stroke rate within 30 days of the procedure was about 1%, though strokes after the first 30 days were estimated at about 7%. (Châteauneuf et al., Heart, 2020) [9]

Key takeaways

• TMVR replaces the mitral valve; it does not repair it. [1]

• It is designed for people with mitral valve disease who are not good candidates for open-heart surgery. [1]

• The new valve is either manufactured or made from cow, pig or human heart tissue. [1]

• Most people stay in hospital for a few days and return to work within several weeks; full recovery can take two to three months. [1]

• Stroke and heart attack symptoms after TMVR need emergency care. [1]

What does the mitral valve do?

The mitral valve is one of the heart's four valves, and it keeps blood moving in one direction from the left atrium (the upper-left chamber) into the left ventricle (the lower-left chamber). It has two flaps, called leaflets, that open and close with every heartbeat. [1]

When the valve works well, blood flows forward only. When it fails, the heart has to work harder. Read more in our guide to understanding the mitral valve.

Which mitral valve problems does TMVR treat?

TMVR treats the two main forms of mitral valve disease: regurgitation and stenosis. People can be born with these problems or develop them later in life. [1]

Severe mitral valve disease can lead to atrial fibrillation, pulmonary hypertension or heart failure. [1]

TMVR can also be used inside a previously placed tissue valve that has worn out ("valve-in-valve") or inside a ring from an earlier valve repair ("valve-in-ring"). [5]

Who is a candidate for TMVR?

TMVR is an option for some people with mitral valve disease who are not good candidates for open-heart surgery. [1] The decision is made by a heart team that weighs each person's anatomy, overall health and the other repair or replacement options available. [3]

Not every heart is suited to the procedure. The mitral valve's large size and position, the need to anchor the new valve securely, and the risk of blocking the heart's outflow path all affect whether TMVR is possible. [3]

Is TMVR the same as MitraClip?

TMVR is not the same as MitraClip: TMVR replaces the faulty valve, while MitraClip is a repair technique that keeps the person's own valve. [1] Both are minimally invasive, but they answer different problems.

Replacement can reduce leakage more completely and more lastingly than catheter repair, but repair remains the first choice for many valve shapes. [2] Your cardiologist will explain which option fits your valve.

How do you prepare for TMVR?

Preparation for TMVR starts with imaging tests, usually an echocardiogram and a CT scan, which help the team plan the procedure. [1] You will also meet an anesthesia specialist to choose between general anesthesia and conscious sedation. [1]

Your care team will give you personal instructions. These often include: [1]

• Stopping certain medicines a few days before the procedure

• Not eating or drinking on the day of the procedure

• Arranging a ride home

What happens during TMVR?

TMVR takes about two to three hours and is performed by a team that includes cardiac surgeons, interventional cardiologists, imaging specialists and anesthesiologists. [1]

The team will: [1]

1. Shave and clean the procedure area.

2. Place an IV line in an arm vein for medicines and fluids.

3. Load the new valve onto the end of a catheter.

4. Make an incision in the groin or chest and insert the catheter into a blood vessel.

5. Use imaging to guide the catheter to the mitral valve.

6. Position the new valve inside the existing valve.

7. Secure the valve in place.

8. Remove the catheter and close the incision.

Throughout the procedure, the team watches your blood pressure, blood oxygen and other vital signs, and uses echocardiography to see the heart's valves and chambers in real time. [1]

The catheter can reach the heart through a vein and across the wall between the upper heart chambers (transseptal route) or through a small opening near the tip of the heart (transapical route). [3]

What are the benefits of TMVR?

The main benefit of TMVR is that it corrects mitral valve disease without opening the chest for open-heart surgery. [1] A transcatheter approach can: [1]

• Correct mitral valve disease

• Improve symptoms caused by the faulty valve

• Lower the risk of serious health problems

• Offer a quicker recovery than open-heart surgery

What are the risks of TMVR?

TMVR carries fewer risks than open-heart surgery, but complications can still happen. [1]

Source: [1]

If needed, the heart team may switch to open-heart surgery during the procedure, and some complications require a second procedure. [1]

What is recovery like after TMVR?

Recovery after TMVR begins in a recovery room, where the team monitors you as the anesthesia wears off. [1] Some people spend a short time in the intensive care unit, and most stay in hospital for a few days. [1]

Source: [1]

Before you leave, your team will explain cardiac rehabilitation, follow-up appointments, your medicines, and when you can go back to work. [1] Follow their timeline before returning to any activity.

When should you call a doctor after TMVR?

After TMVR, signs of a stroke or heart attack need emergency care right away. [1]

Call emergency services for stroke signs: [1]

• Vision changes

• Numbness, tingling, weakness or loss of movement in the face, arm or leg, especially on one side

• Trouble walking or keeping your balance

• Sudden confusion or trouble understanding others

• Sudden, severe headache

• Trouble talking

Call emergency services for heart attack signs: [1]

• Chest pain

• Light-headedness, weakness or fainting

• Nausea and vomiting

• Pain or pressure in the back, neck, jaw, belly, shoulder or arm

• Shortness of breath

Call your care team if you notice: [1]

• Loose stitches or bleeding from the incision

• Pain, colour change (red, purple, dark brown or black) or swelling in the calf, knee, thigh or groin, which may signal a blood clot

• Signs of infection, such as pain, fever, pus, drainage or discoloured streaks on the skin

• Sudden weight gain or swelling in the legs, ankles or feet, which may signal heart failure

Conclusion

Transcatheter mitral valve replacement gives people with serious mitral valve regurgitation or stenosis a way to get a new valve without open-heart surgery. It suits people who are not good candidates for traditional surgery, usually takes two to three hours, and most people are back to their routine within several weeks. Knowing the risks and warning signs helps you recover safely and act fast if something changes.

Next step: If you or a loved one has mitral valve disease, write down your questions and ask your cardiologist whether repair, TMVR or surgery fits your valve best.

What is transcatheter mitral valve replacement (TMVR)?

Transcatheter mitral valve replacement (TMVR) is a procedure that replaces the mitral valve using a catheter instead of open-heart surgery. The new valve takes over the work of the faulty valve. [1]

Who needs transcatheter mitral valve replacement?

Transcatheter mitral valve replacement is for some people with mitral valve regurgitation or stenosis who are not good candidates for open-heart surgery. A heart team decides whether a person's valve and overall health suit the procedure. [1][3]

Is TMVR the same as MitraClip?

TMVR is not the same as MitraClip. TMVR replaces the faulty valve, while MitraClip repairs the person's own valve. [1]

How long does a TMVR procedure take?

A TMVR procedure takes about two to three hours. It is done by a team of heart surgeons, interventional cardiologists, imaging specialists and anesthesiologists. [1]

Are you awake during TMVR?

TMVR is done under general anesthesia or conscious sedation, so you do not feel pain. An anesthesia specialist chooses the best option with you before the procedure. [1]

What are the main risks of TMVR?

The main risks of TMVR are blood clots that can cause a stroke, tissue damage, blockage of blood flow out of the left ventricle, and the new valve moving out of position. Some complications need a second procedure or a switch to open-heart surgery. [1]

How long is recovery after TMVR?

Recovery after TMVR usually means a few days in hospital, a return to work within several weeks, and full recovery in two to three months. Always follow your care team's timeline. [1]

When should I seek emergency care after TMVR?

Seek emergency care after TMVR if you have signs of a stroke, such as face or arm weakness, trouble talking or sudden confusion, or signs of a heart attack, such as chest pain or shortness of breath. [1]

How long is the hospital stay after TMVR?

Many people stay in the hospital for a few days after TMVR, though it depends on the approach used and how you recover. Your care team will tell you when it is safe to go home.

Will I need blood thinners after TMVR?

Most people take a blood thinner for a time after TMVR to help prevent clots on the new valve. Your cardiologist will decide which medicine and for how long.
