Transcatheter Aortic Valve Implantation (TAVI)

Transcatheter aortic valve implantation (TAVI), also known as Transcatheter aortic valve replacement (TAVR) is a treatment for aortic stenosis. It is a minimally invasive procedure that treats the obstructive blood flow in the aortic valve. This unique procedure for aortic valve repair is ideal for patients who are unable to undergo an open heart surgery. These include elderly patients with severe health problems like lung diseases or nephropathy or patients living with other coronary artery diseases or those who have undergone CABG before. Many patients who have suffered a stroke before are also recommended this procedure.

TAVI is usually performed in one of the following ways:

• Transfemoral Approach – The aortic valve is replaced via the femoral artery (located in the thigh) with a catheter.
• Transapical Approach – The aortic valve is replaced via the tip of the heart with a catheter.
• Transaortic Approach – The aortic valve is replaced via the ascending aorta (valve beginnings) with a catheter.
• If you are considering a TAVI procedure in India, contact our team of surgeons to get detailed information about the same.

INDICATIONS
Patients suffering from the following symptoms are generally advised a TAVI procedure:

• Pain the chest, clinically known as angina pectoris
• Experiencing shortness of breath or a constant feeling of exertion may be signs of a forthcoming heart failure
• Loss of consciousness or low blood pressure (syncope)
• An alternating strong and weak heartbeat, also known as Pulsus Alternans
• A light murmur that is a heart with the contraction of heart muscles (Systolic murmur)
• A sound of a high pitch that usually occurs when the aortic valve opens (clinically known as ejection click)

PRE-PROCEDURE
Surgeons need to access the route for TAVI and therefore, a thorough physical examination and review of all tests are done prior to the surgery. The patient must get admitted at least a day before the surgery. Some common tests conducted by the doctor include chest X-ray, blood tests, ECG, etc.

DURING PROCEDURE
Surgeons need to access the route for TAVI and therefore, a thorough physical examination and review of all tests are done prior to the surgery. The patient must get admitted at least a day before the surgery. Some common tests conducted by the doctor include chest X-ray, blood tests, ECG, etc.

An aortic valve replacement is done by an expert cardiac surgeon and his team under local anaesthesia. Typically, the procedure takes about 45-60 minutes. TAVI repairs the functioning of the aortic valve without having to remove the old damaged valve. A bioprosthetic valve is implanted in the chest as a replacement valve.

TAVI procedure involves inserting the catheter through one of the three approaches – Transfemoral, Transapical or Transaortic in order to access the heart. A catheter is a hollow tube that is inserted through the incision made by the surgeon and then guided towards the heart. Surgeons use ultrasounds and X-ray imaging to correctly guide the catheter during the procedure.

Once the catheter is carefully placed, a replacement valve is passed through it. This replacement valve successfully pushes away the damaged valve and takes its place while using it as an anchor. After the doctor is satisfied that the valve is secure, he will remove the catheter.

Since the patient’s heart does not require to be stopped in this procedure (as compared to an open heart surgery), it offers a greater advantage and puts a lesser strain on the body.

POST PROCEDURE
Once the surgery is completed, the patient is moved to the ICU or a cardiac ICU and closely monitored for the next 24 hours. After the patient is stabilized and shows positive development, he is moved to the room and further checked for complications at regular intervals.

Normally, patients can go home after 5-7 days of the surgery. Since it is related to the heart, patients must follow all the instructions given by the doctors to avoid any risks or complications. Usually, they can resume their routines after 4 weeks of the surgery.

RISK AND COMPLICATIONS
As TAVI is a minimally invasive procedure and does not require an open heart surgery, the risks and complications are comparatively lower. However, patients must thoroughly analyse all the possible risks association with the procedure and only then go ahead. The known risks include:

• A conduction defect that can cause irregular heartbeats due to the faulty electrical impulses of the heart
• A possible kidney disease
• Post-surgery valve complications
• Tearing of the surrounding blood vessels
• Calcific embolization
• In rare cases, a stroke or a heart attack
• Heart failure
• Unexpected cardiac death as a result of a sudden malfunctioning of the heart
• However, you don’t need to worry as cardiac surgeons in India are highly experienced in this procedure and will do their best to ensure a successful operation.

MORE INFO
Nearly 30% of people are unable to opt for an open-heart surgery due to old age or some other complications. In such cases, TAVI has proven to give a new ray of hope to patients who normally wouldn’t have a life expectancy of more than a year without any treatment. The approx. The cost would be $6,500 – $ 11,000 and approx. duration will be 7-14 days, patients can live a much better quality of life post TAVI. Many hospitals in India offer state-of-the-art surgical procedures for heart-related disorders along with a special facility of the Cardiac Intensive Care Unit. The post-operative diagnosis is also superior in India, assuring patients of better care after the surgery.
