Aortic Valve Stenosis is one of the most serious heart conditions which need immediate attention. Transcatheter Aortic Valve Implantation (TAVI) is an effective treatment to cure the condition. Our surgeons perform Transcatheter Aortic Valve Implantation (TAVI) procedure on people who have been diagnosed with severe Aortic Stenosis and are considered to be either at a high-risk or too sick for the conventional surgical valve replacement. The procedure repairs the damaged valve in the heart without actually removing it

What Is Transcatheter Aortic Valve Implantation (TAVI)

Transcatheter Aortic Valve Implantation is a minimally invasive surgery in which a new valve is placed within the affected valve. Heart Valves are flaps of tissue that support the movement of blood in the right direction. In Aortic Valve Stenosis, the aortic valve narrows down, restricting the blood flow from the left ventricle to the aorta. This results in an unanticipated pressure build-up in the left atrium. It is a very serious heart condition that may or may not be congenital. TAVI surgery is the most effective treatment for aortic stenosis.

Alternate name of Transcatheter Aortic Valve Implantation (TAVI)

Transcatheter Aortic Valve Implantation (TAVI) is also known as Transcatheter Aortic Valve Replacement (TAVR)

What Are The Indicators For Aortic Valve Stenosis

Any heart problem begins with sudden or gradual uneasiness, and your body starts giving you signals that something is wrong. Generally, we ignore the mild signs and start to take these seriously only when they progress or become persistent. Aortic valve stenosis sometimes might not show any symptoms, and only tests and scans can detect the problem. Some of the common symptoms associated with Aortic Valve Stenosis are as under:

  • Chest pain
  • Murmuring sound while you breathe
  • Palpitations
  • Fainting
  • Breathlessness

Children with congenital Aortic Valve Stenosis may experience:

  • Breathing irregularities
  • Slow or no weight gain
  • Insufficient feeding

What Are the Conditions We Treat With Transcatheter Aortic Valve Implantation (TAVI) or Transcatheter Aortic Valve Replacement (TAVR)?

Some of the major conditions that we treat with Transcatheter Aortic Valve Implantation (TAVI) are listed below:

  • Wearing of the aortic valve in the elderly people
  • The scarring of the aortic valve due to rheumatic fever
  • The congenitally bicuspid aortic valve

A doctor will evaluate you for various conditions before advising you to undergo Transcatheter Aortic Valve Replacement (TAVR). These conditions include:

  • Frailty age
  • Weak heart muscles
  • Previous heart surgery
  • History of stroke
  •  Chronic Obstructive Lung Disease (COPD)
  • Previous radiation treatment to your chest
  • Birth-related heart conditions (congenital heart disease) such as a bicuspid aortic valve
  • History of a heart-affecting infection
  • Having cardiovascular risk factors, such as 
  • Diabetes
  • High cholesterol 
  • High blood pressure
  • Chronic kidney disease
  • Porcelain aorta - Large calcium deposits in ascending aorta (the blood vessel that carries blood away from your heart)

How Is Aortic Valve Stenosis Diagnosed

The doctors may conduct several diagnostic tests and screenings like:

  • ECG
  • Echocardiogram
  • Cardiac MRI
  • Cardiac Catheterisation
  • CT Scan
  • Chest X-ray
  • Exercise test

According to the diagnostic test results, the doctor will identify whether a patient needs to undergo TAVI or not.

What Is The Procedure For Transcatheter Aortic Valve Implantation (TAVI)

TAVI procedure is used to treat most complex Aortic Stenosis conditions. This procedure is either performed on children or people who are not eligible for the other surgical procedures. The various steps involved in the TAVI procedure are as under:

Before The Procedure

Preparation of Transcatheter Aortic Valve Implantation

The patient needs to undergo certain tests before the procedure, such as.

  • CT scan
  • Blood tests
  • Lung tests
  • X rays
  • Quit smoking before the surgery as it can hamper the healing process
  • The doctor may advise you to stop certain medications before the surgery, such as blood thinners ( warfarin, aspirin), over the counter medications, supplements, herbs, vitamins etc.
  • The patient needs to stop eating and drinking several hours before the surgery to prevent nausea and aspiration during the surgery.

During The Procedure

  • STEP 1:The area of the body where TAVI has to be performed is numbed using  general anaesthetics.
  • STEP 2:Balloon valvuloplasty is performed using a catheter (hollow tube) with a balloon attached to one of its tips. This catheter is inserted into an artery either via the groin or by making a keyhole incision on the side of the arm, leg or chest.
  • STEP 3:The catheter is then directed toward the patient’s heart and positioned at the opening of the aortic valve.
  • STEP 4:In this step, the balloon attached to the catheter is gently inflated with  the aim to make room for the placement of a new tissue valve.
  • STEP 5: The new tissue valve is placed in position and expanded using a balloon.
  • STEP 6: The balloon is then deflated and removed along with the catheter.

Finally, a new valve has replaced the damaged valve.

After The Procedure

The patient has to spend a day or two in the intensive care unit for monitoring purposes. However, the overall recovery time is around 12 weeks. After surgery, most people remain asymptomatic and start to feel better. However, they have to take blood-thinning medications for a lifetime to prevent blood clots formation.

Follow up

The patient needs to visit the hospital 1 to 2 weeks after TAVI, then after 1 month,  2-3 months and 1 year after TAVI.
