Aortic Valve Replacement (AVR)

Aortic Valve Replacement (AVR)

Aortic Valve Replacement (AVR) is an advanced cardiac procedure that replaces a damaged, stiff, or leaking aortic valve with a new mechanical or tissue valve. This restores healthy blood flow, improves heart pumping capacity, reduces symptoms, and prevents long-term heart failure or life-threatening complications.

When You Should Consider AVR

• Severe or persistent shortness of breath that limits walking, climbing stairs, or daily activity.

• Chest pain, pressure, or heaviness due to the heart struggling to push blood through a narrowed valve.

• Extreme tiredness or low energy even during simple tasks.

• Dizziness or fainting episodes, especially during exertion.

• Irregular heartbeat or noticeable palpitations, indicating the heart is under stress.

• Swelling in the feet, legs, or ankles, a sign of poor blood circulation or early heart failure.

Conditions That Require AVR

• Severe Aortic Stenosis – the valve becomes narrowed and heavily calcified, restricting blood flow.

• Severe Aortic Regurgitation – the valve leaks and allows blood to flow backward into the heart.

• Congenital valve abnormalities, including bicuspid valves.

• Infection-related valve damage (endocarditis) that weakens or destroys the valve.

• Aged, stiff, or heavily calcified aortic valve due to long-term wear and tear.

How Aortic Valve Replacement Is Performed

• General anesthesia is given to ensure a pain-free and comfortable procedure.

• The surgeon makes either a full chest incision or a minimally invasive cut depending on your case.

• The damaged aortic valve is carefully removed.

• A new mechanical or biological valve is implanted to restore proper blood flow.

• The heart is restarted, and valve function is tested to ensure smooth operation.

• You are shifted to the ICU for continuous monitoring and early recovery.

Types of Aortic Valve Replacement

• Mechanical Valve Replacement
  Long-lasting artificial valve; ideal for younger patients. Requires lifelong blood thinners to prevent clots.

• Biological (Tissue) Valve Replacement
  Made from natural tissue. Offers natural blood flow and usually requires minimal blood thinner use.

• Minimally Invasive AVR
  Smaller incisions, less pain, reduced blood loss, and faster healing.

• Robotic AVR
  Performed using robotic precision tools for high accuracy, minimal scars, and quicker recovery.

• TAVR (Transcatheter Aortic Valve Replacement)
  A non-surgical, catheter-based procedure performed through the groin. Ideal for elderly or high-risk patients.

Pre-Surgery Preparation

• Quit smoking at least 2–3 weeks before surgery for better lung function.

• Keep blood pressure, diabetes, and heart rate well controlled.

• Follow fasting instructions before the procedure.

• Stop blood thinners only if your cardiologist advises.

• Complete all required heart and blood tests before the surgery date.

Pre-Surgery Tests

• ECG to check heart rhythm.

• 2D Echocardiography to evaluate valve structure and pumping strength.

• CT scan or MRI for detailed imaging when needed.

• Coronary Angiography to detect any artery blockages.

• Chest X-ray to assess lung health.

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

Why AVR Is Highly Effective

• Restores normal forward blood flow from the heart.

• Reduces breathlessness and chest discomfort.

• Prevents the heart from becoming enlarged or weak.

• Improves daily stamina, energy levels, and activity tolerance.

• Provides long-lasting results with modern valve technology.

Recovery After AVR

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

• Early walking begins within 24 hours.

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

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

• Return to work: Usually within 6–10 weeks.

Life After AVR

• Avoid smoking permanently to protect the new valve.

• Follow a heart-healthy, low-salt diet for lifelong cardiac wellness.

• Exercise daily with light walking, avoid heavy lifting initially.

• Take medications regularly, especially blood thinners if you have a mechanical valve.

• Join a cardiac rehabilitation program for guided recovery and long-term heart strength.
