Treatment Options

Treatment options for aortic stenosis will depend in part on the severity of your condition. Mild aortic stenosis can be managed with regular observation and medications.¹ If your aortic stenosis becomes more severe, you may need to have your aortic valve replaced.¹

About your heart

The heart is a vital organ that pumps oxygen-rich blood to all parts of the body.1 A healthy heart beats around 100,000 times a day. The heart has four chambers through which blood is pumped with the help of four heart valves. The valves open when the heart pumps to allow blood to flow through.2 They close quickly between heartbeats to make sure blood does not flow backwards.2

Human body anatomy

During the procedure, the doctor will make a small cut in either the groin (1), neck (2) or in a space between your ribs (3).2

 

The doctor will then guide a thin, flexible tube (called a catheter) containing the transcatheter heart valve through the incision, into an artery and to the diseased aortic valve.

 

The transcatheter heart valve will then be placed in the disease valve and begin working immediately. Your doctor will then remove the tube and close the incision.2

 

The procedure takes approximately 1–2 hours. Your treatment team will talk with you about whether you should have a mild sedative or a general anaesthetic for the procedure.2

Benefits of TAVI

 

TAVI is an effective treatment for aortic stenosis. You may start to feel better soon after your procedure because your heart valve is now working properly. Some people may take a little longer to feel better.3

Many TAVI patients report benefits like:3

  • having more energy
  • being able to do everyday activities
  • breathing normally
  • experiencing less pain
  • feeling less anxious

 

Risks of TAVI

 

Please speak to your doctor about any potential risks associated with this procedure that may apply to you.

 

Warnings and precautions

 

Some patients may have a disease that results in more calcium in their blood. This may cause early wear. 

The transcatheter heart valve is only for certain patients. This includes patients with severe AS or failing surgical valves that:

  • cannot have surgery
  • are at high risk for surgery.

At some point the transcatheter heart valve may need to be replaced. How long it lasts varies from patient to patient. Keep appointments with your doctor. Follow all care instructions to ensure the best possible results.

  • Antibiotics are recommended for patients who are at risk of infections.1
  • Patients should stay on blood-thinning medicines after the procedure as instructed. Patients who do not are more likely to have a stroke.3
  • If an MRI scan is required, tell the doctor about the transcatheter heart valve. Tell the doctor if there is a transcatheter heart valve inside a surgical valve. Not doing so could cause injury or death. Any dentist and all doctors need to know about the transcatheter heart valve.

 

FAQS

 

How do I know if my transcatheter heart valve is working properly?

Your doctor will check the valve during the regular follow-up visits.

What kind of exercise can I do with my transcatheter heart valve?

Discuss this with your doctor and they can help advise you what activities you can do.

Can I have an MRI with a transcatheter heart valve?

If you need an MRI, tell your doctor you have a transcatheter heart valve. Not doing so could result in injury or death.
