TAVR (Transcatheter Aortic Valve Replacement)
Dr. Praneeth Polamuri, Senior Consultant Interventional Cardiologist, Yashoda Hospital, Secunderabad
What Is TAVR?
Transcatheter Aortic Valve Replacement (TAVR) is a minimally invasive procedure used to treat "severe aortic stenosis", a condition in which the aortic valve becomes narrowed and restricts blood flow from the heart to the rest of the body.
Think of the aortic valve as the main exit door of the heart. Over time, this door can become stiff and narrow, forcing the heart to work much harder to pump blood.
TAVR allows doctors to replace the diseased valve without traditional open-heart surgery.
What Is Aortic Stenosis?
Aortic stenosis occurs when the aortic valve becomes thickened, calcified, and unable to open fully.
As the valve narrows:
-
Blood flow decreases
-
The heart works harder
-
Symptoms gradually develop
-
Heart failure risk increases
Severe untreated aortic stenosis can be life-threatening.
Common Symptoms of Severe Aortic Stenosis
The classic symptoms are:
-
Chest Pain - A feeling of pressure or heaviness during exertion.
-
Breathlessness - Difficulty breathing during activity.
-
Dizziness or Fainting - Especially while walking or exercising.
-
Fatigue - Reduced energy and stamina.
-
Heart Failure Symptoms - Swelling of feet and worsening breathlessness.
Why Is Early Treatment Important?
Many patients mistakenly believe symptoms are due to aging.However, once symptoms develop, severe aortic stenosis can progress rapidly.
Without treatment:
-
Heart failure may develop
-
Hospitalizations increase
-
Quality of life declines
-
Survival decreases significantly
Timely intervention can dramatically improve symptoms and outcomes.
What Is TAVR?
TAVR involves implanting a new artificial valve inside the diseased aortic valve using a catheter.The new valve immediately begins functioning and restores normal blood flow.
Unlike surgical valve replacement:
-
No large chest incision
-
No heart-lung machine
-
Faster recovery
-
Shorter hospital stay
How Is TAVR Performed?
Step 1: Detailed Evaluation
Patients undergo:
-
Echocardiography
-
CT scan
-
Blood tests
-
Heart Team assessment
Step 2: Access - Through an Artery
Most TAVR procedures are performed through the artery in the groin (femoral artery).
Step 3: Valve Delivery
A compressed valve is advanced through a catheter to the heart.
Step 4: Valve Deployment
The new valve is positioned inside the diseased valve and expanded.The old valve is pushed aside and the new valve takes over immediately.
Step 5: Recovery
Most patients experience rapid improvement in symptoms.
Who Is a Candidate for TAVR?
TAVR may be considered for patients with:
-
Severe symptomatic aortic stenosis
-
Increasing breathlessness
-
Syncope (fainting)
-
Reduced exercise tolerance
Treatment decisions are individualized.
TAVR vs Surgical Valve Replacement
TAVR vs Surgical Valve Replacement
-
Approach: TAVR is minimally invasive (catheter-based). Surgery requires open-heart.
-
Chest opening: TAVR needs no large incision. Surgery requires sternotomy.
-
Heart-lung machine: Not required for TAVR. Required for surgery.
-
Recovery time: TAVR patients recover in days to weeks. Surgery takes 6–12 weeks.
-
Hospital stay: TAVR is typically 2–5 days. Surgery is 5–7 days or more.
-
Anaesthesia: TAVR often uses conscious sedation. Surgery requires general anaesthesia.
-
Outcome: Both treatments deliver excellent results when chosen appropriately.
Treatment decisions are individualised. Dr. Praneeth Polamuri evaluates each patient to recommend the best option.
Benefits of TAVR
TAVR can:
-
Improve breathlessness
-
Improve exercise capacity
-
Reduce heart failure symptoms
-
Improve quality of life
-
Restore normal valve function
-
Avoid open-heart surgery in many patients
What Tests Are Needed Before TAVR?
-
Echocardiogram - Confirms severity of aortic stenosis.
-
CT TAVR Planning Scan - Evaluates anatomy and valve dimensions.
-
Coronary Angiography - Assesses coronary artery disease.
-
Blood Tests - Evaluate overall health.
-
Heart Team Assessment - Determines the best treatment strategy.
Recovery After TAVR
Most patients:
-
Walk within hours
-
Spend only a few days in hospital
-
Resume normal activities quickly
-
Experience symptom improvement within days or weeks
Recovery is generally much faster than after surgery.
What Are the Risks of TAVR?
Like all procedures, TAVR carries risks.
Potential complications include:
-
Bleeding
-
Stroke
-
Pacemaker requirement
-
Valve leakage
-
Blood vessel complications
-
Kidney injury
Fortunately, serious complications are uncommon in experienced centers.
Life After TAVR
Many patients experience:
-
Improved energy
-
Better breathing
-
Greater independence
-
Improved quality of life
Regular follow-up remains important.
A Reassuring Thought
A diagnosis of severe aortic stenosis can be frightening. However, TAVR has transformed the treatment of valve disease and allows many patients to achieve excellent outcomes without undergoing open-heart surgery.-
Frequently Asked Questions (FAQ
1. What is TAVR?
TAVR (Transcatheter Aortic Valve Replacement) is a minimally invasive procedure used to replace a diseased aortic valve without open-heart surgery.
