Mitral Valve Replacement Surgery in Delhi, India

Mitral valve disease occurs when the valve between the heart’s left chambers does not open or close properly, affecting normal blood flow. It may result from conditions such as rheumatic heart disease, age-related calcification, congenital defects, or infections. 

Common symptoms include shortness of breath, persistent fatigue, swelling in the legs or ankles, chest discomfort, or irregular heartbeat. Early diagnosis and timely treatment are key to preventing heart failure and ensuring long-term cardiac health.

Mitral valve replacement is a surgical procedure that involves removing a damaged or diseased mitral valve and replacing it with an artificial one to restore normal blood flow through the heart. The mitral valve ensures that blood flows in one direction, from the left atrium to the left ventricle, and prevents it from leaking backward. When it no longer functions properly due to stenosis, regurgitation, or infection, the heart’s efficiency declines. Replacing the valve allows the heart to pump blood more effectively, alleviating symptoms such as fatigue, breathlessness, and chest discomfort.

When treating mitral valve disease, doctors always aim to repair the natural valve whenever possible, as this offers several long-term benefits. However, repair is not suitable for everyone. Understanding the difference between repair and replacement helps patients know why one approach may be chosen over the other.

Mitral Valve Repair

Mitral valve repair involves preserving the patient’s own valve and restoring its normal function. Surgeons may reshape the valve leaflets, remove excess tissue, correct prolapse, or tighten the surrounding ring (annulus) using an annuloplasty band.

Key advantages of repair include:

• Better long-term heart function
• Reduced risk of infection
• Lower need for long-term blood thinners
• Faster recovery
• Better durability for certain types of valve problems (especially degenerative mitral regurgitation)

Repair is typically preferred when the valve anatomy is suitable, such as in cases of degenerative (floppy) mitral regurgitation.

Mitral Valve Replacement

When the valve is too damaged, stiff, or infected to be repaired, replacement becomes the safer and more reliable option. In this procedure, the diseased valve is removed and replaced with either a mechanical or biological(tissue) valve.

Replacement is usually recommended when:

• The valve is heavily calcified
• There is severe rheumatic damage
• Repair would not provide lasting results
• Infection (endocarditis) has destroyed valve tissue
• A previous repair has failed

Although replacement sometimes involves a longer recovery and ongoing medication depending on the valve type, it offers a durable and effective solution for complex or advanced disease.

How Doctors Decide Between Repair and Replacement

At Max Hospitals, our doctors use a comprehensive evaluation, combining echocardiography, CT scans, and a detailed cardiac team assessment, to identify the option that offers the best long-term results. The goal is always to choose the strategy that will:

• Restore normal valve function
• Reduce symptoms
• Prevent future complications
• Improve overall quality of life

Mitral valve replacement is usually advised when the natural valve is too damaged to be repaired. It may also be recommended when repair surgery is unlikely to provide durable results. Common indications include:

• Severe mitral stenosis (narrowing of the valve opening) due to rheumatic heart disease or calcium build-up.
• Mitral regurgitation, where the valve does not close properly, allowing blood to leak backward.
• Infective endocarditis, where infection damages the valve tissue beyond repair.
• Congenital abnormalities that prevent normal valve function.
• Failed previous mitral valve repair or replacement requiring reoperation.

Before recommending replacement, our cardiologists and cardiac surgeons at Max Hospitals conduct detailed echocardiographic evaluations, cardiac MRI, and cardiac catheterisation to assess valve structure, heart function, and overall surgical suitability.

The choice of valve plays a crucial role in determining the long-term success of the procedure. The selection depends on age, lifestyle, medical condition, and individual treatment goals.
The two main types of replacement valves are:

Mechanical Valves

Made from durable materials such as titanium or carbon, mechanical valves are designed to last a lifetime. However, they require lifelong anticoagulation medication to prevent clot formation.

Biological (Tissue) Valves

Derived from animal tissue (usually pig or cow) or donated human valves, these do not require long-term anticoagulation but may need replacement after 10–20 years, depending on wear.

At Max Hospitals, our cardiac specialists help select the most suitable valve based on the patient’s specific medical profile and future lifestyle considerations.

Getting Ready (Days Before the Procedure)

Preparation begins several days before surgery to ensure complete readiness. Patients undergo comprehensive diagnostic assessments, including blood tests, echocardiograms, chest X-rays, and sometimes coronary angiography. The cardiac team also reviews current medications, allergies, and any pre-existing conditions.

Nutritional advice, breathing exercises, and counselling sessions are provided to strengthen the body and ease anxiety. Anaesthesiologists and cardiac care coordinators explain each step of the process, ensuring mental preparedness and smooth coordination across teams.

On the Day of the Procedure - What to Expect

On the day of surgery, patients are admitted to the hospital, where the cardiac team prepares them for the operation. After administering general anaesthesia, the surgical team begins the procedure, which typically lasts between three to five hours.

In traditional open-heart surgery, a small incision is made in the chest to access the heart, and the patient is connected to a heart-lung bypass machine that maintains circulation. The damaged valve is carefully removed and replaced with the chosen prosthetic valve.
In minimally invasive or robot-assisted procedures, smaller incisions are made between the ribs, allowing for faster recovery and reduced discomfort.

Throughout the procedure, the surgical and anaesthesia teams monitor vital functions with precision, ensuring complete safety and stability at every step. Once completed, the patient is moved to the cardiac intensive care unit (CICU) for close observation.

Post-Procedure Recovery and Care (at Home)

Initial recovery takes place in the CICU, where heart rhythm, breathing, and blood pressure are monitored continuously. Most patients can begin gentle movement within 24 hours and are encouraged to start physiotherapy and breathing exercises early to aid recovery.

After discharge, ongoing recovery continues at home. Adhering to prescribed medications — including blood thinners for mechanical valves — is essential. A heart-healthy diet, regular follow-ups, and gradual physical activity help restore strength and endurance. Emotional support and lifestyle counselling at Max Hospitals guide patients in adapting to life after surgery, focusing on long-term cardiac wellness and quality of life.

Mitral valve replacement is a major procedure, but when performed by skilled cardiac surgeons in advanced facilities, it is generally safe. Nevertheless, like all heart surgeries, it carries some risks. These may include:

Bleeding and Infection

A small degree of bleeding is expected after surgery, but excessive bleeding or wound infection may occasionally occur. These are minimised through precision surgical techniques, sterile protocols, and timely antibiotic support.

Blood Clots and Stroke

Clot formation is a recognised risk following valve surgery, particularly with mechanical valves. Continuous blood-thinning therapy, early mobilisation, and regular monitoring help reduce the likelihood of clots or stroke.

Irregular Heart Rhythms (Arrhythmias)

Temporary rhythm disturbances may develop due to changes in the heart’s electrical pathways during surgery. Continuous ECG monitoring in the intensive care unit enables early detection and management of such issues.

Valve Malfunction or Degeneration

Tissue valves may gradually wear out over time, while mechanical valves, though long-lasting, require careful follow-up. Regular echocardiography ensures ongoing assessment of valve performance and early intervention if required.

Anaesthesia Reactions and Anticoagulant Complications

All anaesthesia procedures carry a small degree of risk, which is minimised through thorough preoperative evaluation. For those with mechanical valves, anticoagulant therapy is essential but must be closely managed to prevent excessive bleeding or clotting. Dedicated anticoagulation clinics at Max Hospitals ensure optimal medication balance.

Respiratory and Renal Complications

In some individuals, temporary breathing difficulties or kidney strain may arise after surgery. Intensive care monitoring, early physiotherapy, and prompt intervention support smooth recovery.

Emotional and Physical Fatigue

Recovery can bring short-term tiredness or emotional strain. Counselling, cardiac rehabilitation, and family education programmes at Max Hospitals help patients regain confidence and resume normal routines with ease.

At Max Hospitals, these risks are minimised through careful patient selection, advanced imaging, precision surgical planning, and comprehensive postoperative monitoring.

Recovery after mitral valve replacement extends beyond the hospital stay. With appropriate care, most patients return to normal activities within a few weeks and experience marked improvement in stamina and overall wellbeing.

Lifestyle modifications, including a balanced diet, regular physical activity, and avoidance of smoking, play a vital role in maintaining heart health. Ongoing follow-ups, echocardiographic evaluations, and cardiac rehabilitation sessions help ensure the replaced valve continues to function optimally.
