Essential insights into mitral valve replacement surgery, from preparation to rehabilitation and long-term care.

Mitral Valve Replacement Overview

The mitral valve is a vital component of the heart that helps control blood flow between the left atrium and left ventricle. When the mitral valve is damaged by disease, aging, or birth defects, it may not function properly—requiring repair or replacement to help the heart pump effectively and prevent complications like heart failure or stroke.

Who Needs Mitral Valve Replacement?

Mitral valve replacement is typically recommended when:

The valve is too damaged for repair—this can result from mitral valve stenosis (narrowing) or mitral regurgitation (leakage).
Symptoms such as shortness of breath, fatigue, swelling, or heart rhythm problems persist despite medical management.
Other treatments, including mitral valve repair, are not possible or have failed.

Replacement may also be needed for those with birth defects, certain infections (like endocarditis), or valve damage due to rheumatic heart disease.

Different Types of Mitral Valve Procedures

Physicians will determine the best treatment based on the type and severity of your valve problem, your general health, and other medical conditions. The main options include:

Mitral Valve Repair: Preferred when possible, it preserves your own valve with less need for long-term blood thinners. Techniques may include patching the valve, tightening it with a ring (annuloplasty), or replacing damaged sections.
Mitral Valve Replacement: Necessary when repair is not possible. The damaged valve is removed and replaced with an artificial (prosthetic) valve.

Types of Replacement Valves

Valve Type	Material	Benefits	Limitations
Mechanical Valve	Durable artificial materials (metal, pyrolytic carbon)	Long-lasting—often over 20 years	Requires lifelong blood thinners (anticoagulation)
Biological Valve	Tissues from cows (bovine), pigs (porcine), or donated human tissue	No long-term need for blood thinners; more natural	Less durable (often needs replacement in 10–15 years)

Your doctor will help you choose the best valve based on your age, lifestyle, medical history, and personal preference.

Surgical Approaches to Mitral Valve Replacement

There are two main approaches to mitral valve surgery:

Open-Heart Surgery: A traditional method involving a larger incision in the chest, allowing direct access to the heart.
Minimally Invasive Surgery: Uses smaller incisions (2–4 inches) or keyhole cuts. Special instruments and sometimes robotic assistance help perform the procedure with less trauma to tissue.

Both techniques generally require use of a heart-lung machine (cardiopulmonary bypass) to take over circulation while the heart is stopped and repaired or replaced.

Minimally Invasive and Robotic-Assisted Techniques

Endoscopic Surgery: Small cuts are made, and a camera with instruments are used to perform the procedure.
Robotic-Assisted Surgery: Surgeons use robotic arms controlled via a computer system, improving precision and allowing for the smallest incisions possible.

Minimally invasive approaches often result in:

Less pain
Reduced hospital stay
Lower risk of complications
Faster recovery and return to daily activities

What to Expect Before Surgery

Preparation for mitral valve surgery includes:

Thorough heart evaluation with tests like echocardiogram, EKG, chest X-ray, and blood work
Review of medications (certain drugs may need to be adjusted or stopped before surgery)
Anesthesia assessment and discussion of personal and family medical history
Instructions to avoid eating or drinking for several hours before surgery

What Happens During Mitral Valve Replacement?

The steps of a typical mitral valve replacement procedure include:

Anesthesia: You will be given general anesthesia and are fully asleep and pain-free.
Incisions: The surgeon makes the appropriate incisions (open or minimally invasive).
Access to the Heart: The heart-lung machine temporarily takes over to circulate blood.
Valve Replacement: The damaged mitral valve is removed. A new mechanical or biological valve is sewn into place.
Closing Incisions: The heart is restarted, circulation returns to normal, and incisions are closed. Drainage tubes may be placed to prevent fluid buildup.

The whole procedure generally lasts several hours.

After Surgery: Hospital Recovery

Immediately after mitral valve replacement, you can expect to:

Spend one or more days in an intensive care unit (ICU) for close monitoring.
Be connected to several tubes and monitors (for breathing, fluids, heart function, and blood pressure).
Gain increased activity and movement as tolerated, with pain managed through prescribed medications.
Receive instructions on wound care, medication regimens, and recognizing signs of infection or complications.

Most people transition to a regular hospital room within a couple of days and are discharged after about 5–10 days, depending on the type of surgery and their overall health.

Recovery at Home and Cardiac Rehabilitation

Recovery at home takes several weeks:

Total recovery time: 4 to 8 weeks, depending on surgery type and personal health.
Activity is increased gradually—from walking around the house to returning to work or normal activities (as cleared by your surgeon).
Minimally invasive surgery patients often recover faster than those with open-heart surgery.
Some people may need additional assistance at home or outpatient rehabilitation support.

Cardiac Rehabilitation Programs

Personalized exercise and fitness plans
Diet and nutrition counseling
Education on heart health, medications, and symptom monitoring
Support for emotional and mental health during recovery

It’s crucial to attend all follow-up appointments and call your doctor if you experience fever, worsening pain, excessive redness or swelling at the incision, difficulty breathing, palpitations, or other concerning symptoms.

Risks and Potential Complications

Mitral valve replacement, though generally safe, is a major surgery and carries certain risks, including:

Bleeding or infection
Heart rhythm problems
Blood clots and stroke
Lung or kidney problems
Valve dysfunction (rare, but may require reoperation)

Certain factors may increase risk, including advanced age, diabetes, kidney disease, or having other serious medical conditions. Discuss all potential risks with your surgical team prior to the procedure.

Living with a Mitral Valve Replacement

After successful recovery, most individuals return to normal activities and experience an improved quality of life. Some important considerations include:

Medications: If you received a mechanical valve, you will need lifelong anticoagulant medication. Biological valve recipients may not require these medications long-term.
Regular doctor visits: Monitor heart function, blood pressure, and signs of valve function issues.
Healthy lifestyle: Maintain a heart-healthy diet, monitor cholesterol, avoid tobacco, and manage stress.
Dental care: Good oral hygiene and prompt treatment of infections to reduce the risk of heart infection (endocarditis).

FAQs: Mitral Valve Replacement

Q: How do I know if I need mitral valve replacement or repair?

A: Your surgeon will assess the degree and cause of valve damage. When repair isn’t possible or would not be durable, replacement is advised.

Q: What is the difference between mechanical and biological valves?

A: Mechanical valves last longer but require lifelong blood-thinning medications. Biological valves are less durable, but blood thinners are typically not needed after the initial recovery period.

Q: How long will it take to recover?

A: Most people recover within 4 to 8 weeks, although those who undergo minimally invasive procedures might return to normal activity sooner.

Q: What are the main risks of the procedure?

A: All heart surgeries carry risks, including infection, bleeding, arrhythmias, blood clots, and rare instances of valve malfunction or need for repeat surgery.

Q: Will I be able to live a normal life with a new mitral valve?

A: Most patients return to their usual activities, including work and exercise, once fully recovered. Ongoing follow-up and healthy habits are important for lifelong heart health.
