Transcatheter Aortic Valve Replacement (TAVR)

Transcatheter Aortic Valve Replacement (TAVR)

Transcatheter Aortic Valve Replacement (TAVR) is a minimally invasive procedure used to replace a narrowed aortic valve that fails to open properly—a condition known as aortic stenosis. It’s a game-changer, especially for patients who are at high or intermediate risk for open-heart surgery.

TAVR offers a safer, faster recovery alternative with excellent outcomes.

Doctors may suggest TAVR for patients who:

• Have severe symptomatic aortic stenosis
• Are not eligible for open-heart surgery
• Are elderly or have multiple medical conditions
• Need a less invasive treatment approach
• Show worsening heart failure symptoms due to valve narrowing

TAVR is FDA-approved for low, intermediate, and high-risk surgical patients.

How the TAVR Procedure Works

• Access Site: A catheter is inserted through the femoral artery in the groin (or sometimes through other arteries).
• Valve Delivery: A collapsed artificial valve is advanced through the catheter to the heart.
• Deployment: Once correctly positioned, the valve expands, pushing the old valve aside.
• Function Restored: The new valve immediately takes over the job of regulating blood flow from the heart to the body.

The entire process is monitored using real-time imaging and usually takes 1–2 hours.

Types of TAVR Valves

• Balloon-expandable valves
• Self-expanding valves
• Mechanically expandable valves

The choice depends on patient anatomy, disease severity, and physician preference.

TAVR vs. Open-Heart Surgery

TAVR offers quicker recovery and less physical stress, especially for older adults.

Benefits of TAVR

• No need for open-heart surgery
• Shorter hospital stay and recovery
• Improved heart function and symptoms
• Lower risk of complications in high-risk patients
• Immediate improvement in quality of life

It’s a preferred option for patients who can’t undergo surgery due to age or health conditions.

Risks and Considerations

While TAVR is safe and effective, potential risks include:

• Bleeding or vascular complications
• Valve leakage (paravalvular regurgitation)
• Stroke or heart attack
• Infection
• Pacemaker requirement post-procedure

These are rare and managed effectively by experienced heart teams.

Post-TAVR Care and Follow-Up

• Monitoring in a cardiac recovery unit
• Regular echocardiograms to assess valve performance
• Medications to prevent blood clots or infections
• Lifestyle changes to support heart health
• Close follow-up with the cardiologist

Most patients return to normal activities within 7–14 days.
