Mitral Valve Replacement (MVR)

Mitral Valve Replacement (MVR) (Cardiology)

Mitral Valve Replacement (MVR) is a specialized heart procedure that restores healthy blood flow by replacing a diseased mitral valve with a mechanical or biological valve. This improves heart efficiency, reduces symptoms like breathlessness and fatigue, and prevents long-term complications such as heart failure.

When You Should Consider MVR

• Shortness of breath during daily activities or while lying down.

• Chest discomfort or pressure caused by poor blood flow through the heart.

• Fatigue or low energy during simple tasks.

• Irregular heartbeat or palpitations due to valve dysfunction.

• Swelling in feet, legs, or ankles from fluid retention.

• Fainting or dizziness, especially during physical activity.

Conditions That Require MVR

• Severe Mitral Stenosis – narrowing of the mitral valve restricting blood flow.

• Severe Mitral Regurgitation – leaking mitral valve causing backward blood flow.

• Congenital mitral valve defects present from birth.

• Valve damage from infection (endocarditis).

• Calcified or thickened mitral valve leading to poor heart function.

How Mitral Valve Replacement Is Performed

• General anesthesia is administered for a safe, painless procedure.

• A chest or minimally invasive incision is made based on patient suitability.

• The damaged mitral valve is carefully removed.

• A mechanical or biological replacement valve is implanted.

• Heart function is tested before closing the incision.

• Patient is moved to the ICU for monitored recovery.

Types of Mitral Valve Replacement

• Mechanical Valve Replacement
  Long-lasting artificial valve; requires lifelong blood thinners.

• Biological (Tissue) Valve Replacement
  Natural tissue valve; usually requires minimal blood thinner use.

• Minimally Invasive MVR
  Smaller incisions, less pain, quicker healing, and reduced scarring.

• Robotic MVR
  Uses robotic precision for high accuracy, minimal scarring, and faster recovery.

• Transcatheter Mitral Valve Replacement (TMVR)
  Non-surgical, catheter-based procedure for high-risk or elderly patients.

Pre-Surgery Preparation

• Stop smoking 2–3 weeks before surgery.

• Maintain blood pressure, diabetes, and heart rate within target range.

• Follow fasting instructions as advised.

• Pause blood thinners only if instructed by your cardiologist.

• Complete all cardiac and routine blood tests prior to surgery.

Pre-Surgery Tests

• ECG to check heart rhythm.

• Echocardiography (2D/3D) to evaluate mitral valve function.

• CT or MRI scans for detailed imaging if required.

• Coronary angiography to detect any blocked arteries.

• Chest X-ray to assess lung and heart health.

• Routine blood tests including CBC, kidney/liver function, and clotting profile.

Why MVR Is Highly Effective

• Restores normal blood flow through the heart.

• Reduces shortness of breath, fatigue, and chest discomfort.

• Prevents heart enlargement and failure.

• Improves daily activity tolerance and quality of life.

• Provides long-lasting results with modern valve options.

Recovery After MVR

• ICU stay: 1–2 days for close monitoring.

• Walking usually begins within 24 hours.

• Tubes and drains are removed in 48–72 hours.

• Home recovery: 4–8 weeks depending on the procedure type.

• Return to work: Typically 6–10 weeks, gradually increasing activity.

Life After MVR

• Avoid smoking permanently.

• Follow a heart-healthy, low-salt diet.

• Engage in daily light exercise; avoid heavy lifting initially.

• Take prescribed medications regularly, especially blood thinners for mechanical valves.

• Join a cardiac rehabilitation program for optimal long-term recovery.
