Mitral Valve Repair

Overview

Mitral valve repair is surgery to fix the mitral valve — the valve between the left upper and lower chambers of the heart — so that it opens and closes properly and blood flows in one direction. The mitral valve most often needs attention because it becomes leaky (mitral regurgitation), commonly due to degenerative disease or prolapse, where the valve leaflets stretch and no longer seal tightly.

Repair techniques may include removing or reshaping excess valve tissue, repairing or replacing the fine cords (chordae) that tether the valve, and placing a supportive ring around the valve opening (annuloplasty) to restore a tight seal. When it is feasible, mitral repair is generally preferred over replacement because it preserves the natural valve, protects heart function, and often avoids lifelong blood thinners.

This page is an educational overview only — it is not medical advice, and no outcome can be guaranteed.

Who May Need This

Mitral valve repair may be considered for people with significant mitral regurgitation who have symptoms such as breathlessness, fatigue, palpitations, or reduced exercise tolerance, or whose heart is showing early signs of strain — such as enlargement of the left ventricle or a fall in pumping function — even before symptoms appear.

Not every mitral valve can be repaired; the feasibility depends on the cause and pattern of the damage. Degenerative disease and prolapse are often highly repairable, while heavily damaged or rheumatic valves may need replacement. Eligibility is determined by a cardiologist and cardiac surgeon after detailed imaging, ideally at a centre experienced in mitral repair.

When It May Be Recommended

Repair may be recommended when mitral regurgitation is severe and causing symptoms, or when imaging shows the left ventricle beginning to enlarge or weaken, or a new irregular heart rhythm developing — signs that the heart is being strained. Acting before permanent heart damage occurs is an important goal, and this often means operating relatively early for repairable valves.

The decision weighs the benefits of fixing the valve against the risks of surgery and considers alternatives such as monitoring, medication, or a transcatheter approach. A heart team discussion, and the likelihood of a successful durable repair, guide the timing.

Diagnosis and Evaluation

The central test is an echocardiogram, which shows the mitral valve in detail and measures the severity of the leak. A transoesophageal echocardiogram (a probe passed into the food pipe) gives especially clear views and helps the surgeon plan the repair. Evaluation also includes a history and examination, an electrocardiogram (ECG), and blood tests.

Before surgery, coronary angiography checks for artery blockages, and additional imaging such as cardiac CT or MRI may be used. Because the repairability of the valve depends on precise anatomy, detailed imaging and an experienced surgical assessment are essential. A second opinion may be valuable.

Treatment Options

Options for mitral regurgitation range from monitoring and medication (to manage symptoms and related conditions such as high blood pressure or atrial fibrillation) to surgical repair, transcatheter repair for selected higher-risk patients, and valve replacement when repair is not feasible. Medication can ease symptoms but does not fix the valve.

Surgical repair can be performed through the breastbone or via a minimally invasive small incision, sometimes with robotic assistance. The best option depends on the cause and severity of the leak, the valve anatomy, and the person’s overall surgical risk.

How It Is Performed

Surgical mitral repair is performed under general anaesthesia. The surgeon reaches the heart through the breastbone or a smaller incision between the ribs, and a heart-lung bypass machine takes over the work of the heart and lungs so the surgeon can work on the still valve. The valve is examined directly, and the repair is tailored to the problem — trimming or reshaping leaflets, repairing the supporting cords, and usually stitching a supportive ring around the valve.

The repair is tested by filling the heart with fluid to check for leakage before the heart is restarted and the chest closed. In a transcatheter edge-to-edge repair, a clip device is guided through a vein to the valve and clipped onto the leaflets to reduce the leak, without opening the chest.

Preparation

Preparation includes completing pre-operative tests, reviewing medications with your team — especially blood thinners — and following fasting instructions. Because dental infection can affect heart valves, a dental check may be advised beforehand.

If you are travelling for treatment, arrange for the recommended in-country stay, bring copies of your echocardiogram and cardiac records, and organise support for the early recovery period. Ask about activity restrictions and when it will be safe to fly home.

Benefits and Expected Goals

The goals of mitral repair are to stop or greatly reduce the leak, relieve symptoms such as breathlessness and fatigue, protect the heart muscle from progressive strain, and — by preserving your own valve — often avoid lifelong blood thinners. For degenerative disease, repair in experienced hands offers excellent and durable results for many people.

Benefits vary by individual and depend on the cause of the leak and how early it is treated. Repair addresses the valve problem but requires ongoing follow-up. Your surgeon can discuss realistic goals for your situation.

Risks and Possible Complications

As heart surgery, mitral repair carries real risks, influenced by age, heart function, and other health conditions.

• Bleeding, infection, or delayed wound healing
• Irregular heart rhythms, including atrial fibrillation, sometimes needing a pacemaker
• Stroke, heart attack, or kidney problems around the time of surgery
• Recurrence of leakage over time, occasionally needing a further procedure
• Rarely, the need to convert to valve replacement during the same operation, or later valve infection (endocarditis)

Your surgical team will explain the risks specific to your health and how they are minimised and managed. Report any concerning symptoms promptly during recovery.

Recovery, Follow-up & Aftercare

After open surgery you will spend time in intensive care before a ward, with a typical stay of about five to seven days; minimally invasive and transcatheter repairs often mean a shorter stay. The chest takes several weeks to heal, so lifting and driving are restricted at first, and most people gradually return to normal activities over several weeks.

You may need blood thinners for a short period, particularly if you have an irregular heart rhythm, and antibiotics before some dental or surgical procedures. Cardiac rehabilitation, wound care, and regular follow-up echocardiograms help protect the result. If treated abroad, arrange follow-up with your local cardiologist before travelling home, and avoid flying until cleared.

Medical Tourism Planning

Because mitral repair success depends heavily on surgical expertise, if you are considering treatment abroad choose a JCI- or ISO-accredited hospital with a high-volume mitral repair programme and surgeons with a strong repair rate. On-site intensive care and advanced echocardiography are important. Request a written treatment plan and cost estimate before you travel.

Plan for the in-country stay your team recommends for surgery, recovery, and clearance to fly, and confirm what medications and follow-up you will need. Arrange continuing care and cardiac rehabilitation with your cardiologist at home, and consider medical travel insurance that covers cardiac procedures.

Estimated Cost Factors

The cost of mitral repair depends on the country and hospital chosen, the surgeon’s and anaesthetist’s fees, whether the approach is open, minimally invasive, robotic, or transcatheter, the length of hospital and intensive-care stay, and any additional procedures or complications. Pre-operative imaging, medications, and cardiac rehabilitation also add to the total.

Many international destinations offer mitral surgery at a fraction of typical US prices, but figures vary widely by case, and device-based repairs can differ in cost. Prices quoted online are only estimates — always request a personalized written quote that lists exactly what is included before making any decision.

Choosing a Hospital or Specialist

Look for a hospital with recognised accreditation (JCI, ISO, or a strong national equivalent), a dedicated cardiac surgery unit, and surgeons with a high mitral repair rate and specific experience in the technique you may need — open, minimally invasive, robotic, or transcatheter. Experienced imaging and intensive-care teams matter.

Ask about the surgeon’s repair-versus-replacement statistics for degenerative mitral disease, international patient services, interpreter support, and how follow-up and any emergencies would be handled. Transparent, written cost and treatment plans are good signs of a quality programme.

Alternatives

Depending on your valve, alternatives may include watchful monitoring for milder leaks, medication to manage symptoms and related conditions, transcatheter edge-to-edge repair for selected higher-risk patients, and mitral valve replacement when repair is not feasible.

Each option has different benefits, risks, durability, and follow-up needs. A heart team weighing your imaging, symptoms, and overall risk can help you compare repair with the alternatives so the plan fits you.

Questions to Ask Your Doctor

• Can my mitral valve be repaired rather than replaced, and how likely is a durable repair?
• What is your mitral repair rate, and how many of these procedures do you perform each year?
• Would an open, minimally invasive, robotic, or transcatheter approach be best for me?
• Should I have surgery now, or is it safe to monitor the valve for a time?
• What are the specific risks in my case, and what is the plan if repair is not possible during surgery?
• How long is the hospital stay, and when can I drive, work, and fly again?
• What is included in the written cost estimate?
