Heart Valve Repair
The heart contains four valves — mitral, aortic, tricuspid, and pulmonary — that control blood flow in one direction. When a valve leaks, stiffens, or fails to close properly, the heart must work harder to pump blood. Heart Valve Repair is a surgical procedure aimed at correcting malfunctioning heart valves without replacing them. This is done utilizing some highly sophisticated surgical processes on the patient’s native valve and using his own tissues such that the valves start functioning well again. Valve repair restores normal function, preserves natural tissue, and helps maintain the heart’s efficiency and overall performance.
Why Is Heart Valve Repair Performed?
Heart valve repair is recommended for patients suffering from conditions such as valve regurgitation (leakage) or stenosis (narrowing). Common causes include degeneration of valve with age, congenital defects, rheumatic heart disease, or infection. Repair is often preferred over replacement because it preserves the native valve, reduces the need for lifelong medications, and offers better long-term results, especially for degenerative mitral and tricuspid valve disease when performed in experienced centres.
Advantages of Heart Valve Repair
Heart valve repair has several benefits compared to valve replacement:
Preserves the natural valve structure and function.
Reduces the risk of infection (endocarditis).
Often eliminates the need for lifelong blood thinners
Improves heart performance and maintains better overall circulation.
Promotes faster recovery and long-term durability.
Patients undergoing valve repair generally experience fewer complications and enjoy a more natural heart function after surgery.
In many studies, successful valve repair has been associated with better long-term survival, improved heart function, and a lower risk of stroke or infection compared with valve replacement, particularly in suitable mitral valve cases.
Common Types of Valve Repair Procedures
Annuloplasty: This procedure tightens or reinforces the ring (annulus) around the valve by sewing a ring or band to restore its shape and support.
Leaflet Repair: If valve leaflets (flaps) are torn, stretched, or damaged, surgeons reshape or reattach them to ensure proper closure.
Chordal Repair or Replacement: Involves repairing or replacing the thin tendons (chordae tendineae) that control valve motion, commonly done in mitral valve surgeries.
Commissurotomy:Used for valves narrowed by scar tissue, this procedure carefully separates fused valve flaps to improve blood flow.
Each technique is customized based on the type of valve affected and the severity of the problem.
For certain aortic valve and aortic root conditions, advanced valve-sparing procedures (such as David or Yacoub procedures) may also be used to preserve the patient’s own aortic valve while treating the diseased aortic root.
How Heart Valve Repair Surgery Is Performed
Heart valve repair can be done as traditional open-heart surgery or through minimally invasive open-heart surgery. During open-heart surgery, the patient is placed under general anesthesia. Traditional open-heart surgery is performed by cutting open the breastbone (sternum) whereas in minimally invasive approaches much smaller incisions are made in between the ribs either on the front or on the left side of the chest wall, without cutting any bone to reach the heart (see our section on minimally invasive cardiac surgery for more details on this). In both the methods, during the operation, patient is attached to an advanced machine called heart lung machine, which performs the function of the heart and lungs for the duration of the surgery, so that heart can be stopped temporarily and procedure can be performed in a bloodless field while the machine is supporting the circulation in the rest of the body. Once heart is stopped the surgeon cuts open the respective chamber of the heart and repairs the damaged valve utilizing one or a combination of many highly specialized and complex repair technique described above. Once done, the repaired valve is checked and the chamber of the heart is closed, heart is made to beat again, and patient is separated from the heart lung machine. In the operation theatre a Trans
Esophageal Echocardiogram (TEE) is performed before closing his chest to confirm and ensure that the repaired valve and the heart is functioning well.
Recovery After Heart Valve Repair
Most patients spend 4 to 7 days in the hospital after surgery. Recovery at home usually takes 4 to 6 weeks, depending on the procedure type and overall health. Extremely rarely some patients may take longer to regain full strength.
Risks and Complications
Although heart valve repair is safe and highly effective, potential risks include bleeding, infection, irregular heartbeat, or recurrence of valve leakage. In some cases, further intervention or reoperation may be required if the valve repair fails or the leak returns over time.
Risks vary from patient to patient and are dependent of multiple other factors. If you have been advised an heart valve repair operation, discuss all the risks and benefits and possible scenarios with your surgeon before you can take an informed decision.
Heart Valve Repair vs. Valve Replacement
Whether to choose a repair or replacement – is a natural question in minds of people diagnosed with a heart valve disease and advised a heart valve operation.
Not all damaged valves can be repaired, and not all patients are suitable candidates for heart valve repair surgery. A Heart Team—comprising a cardiac surgeon, an echocardiologist, a structural heart disease specialist, and a cardiac intensive care specialist—carefully evaluates each patient’s valve condition through a series of diagnostic tests to determine whether the valve can be repaired. In our practice, the Heart Team’s opinion is shared and discussed with the patient, and an informed decision regarding the most appropriate procedure is made jointly by the patient and the Heart Team.
Wherever a valve can be repaired a Valve Repair is considered the preferred option because it preserves the patient’s own tissue, resulting in better durability and natural function. Valve replacement, on the other hand, is recommended when the damage is too severe to repair.
Since heart valve repair surgery eliminates the need for lifelong use of blood-thinning medications, it is a strongly recommended approach, particularly for women of childbearing age who may plan a pregnancy, as such medications may pose a risk of fetal abnormalities.
In some high-risk patients who are not suitable for open surgery, catheter-based repair options (such as transcatheter edge-to-edge repair for the mitral valve) may also be considered, based on a detailed evaluation by the Heart Team.
Frequently Asked Questions
What is heart valve repair?
Heart valve repair is a surgery in which the patient’s own valve is preserved and repaired instead of replacing it with an artificial valve.
Why is valve repair preferred over replacement?
Because repaired valves:
Work more naturally
Do not require lifelong blood thinners (in most cases)
Have lower risk of infection
Provide better long-term heart function
Which valves can be repaired?
Most commonly:
Mitral valve
Tricuspid valve
Aortic valve repair is possible in select patients depending on valve condition.
What conditions need valve repair?
Repair is commonly done for:
Valve leakage (regurgitation)
Valve prolapse
Congenital abnormalities
Some cases of stenosis (narrowing)
How is valve repair done?
Valve repair techniques include:
Reshaping or tightening the valve leaflets
Removing extra tissue
Repairing torn leaflets
Annuloplasty (placing a ring to support the valve)
Can valve repair be done through minimally invasive or robotic surgery?
Yes. Many mitral and tricuspid valve repairs can be performed through small cuts, including keyhole and robotic techniques.
What is the recovery time after valve repair?
Most patients recover within:
Hospital stay: 3–5 days
Full recovery: 4–6 weeks
Minimally invasive approaches may allow faster recovery.
Will I need blood thinners after valve repair?
Usually no lifelong blood thinners are required, unlike mechanical valve replacement.
Some patients may need short-term blood-thinners depending on rhythm or other conditions.
How long does a repaired valve last?
A well-repaired valve can last many years, often lifelong, depending on the type and severity of disease.
Who is a good candidate for valve repair?
You may be suitable if:
The valve is leaking but its basic structure is good
You are young or wish to avoid blood thinners
You want a more natural long-term option
Your surgeon will decide feasibility after detailed echo assessment.
