Transcatheter Aortic Valve Implantation (TAVI): Before Your Procedure
What is transcatheter aortic valve implantation?
Transcatheter aortic valve implantation (TAVI) is a procedure to implant a replacement aortic valve in the heart. It is also called transcatheter aortic valve replacement (TAVR). Your doctor will use a thin, flexible tube called a catheter to put in your new heart valve.
Your doctor will put the catheter into a blood vessel in your upper leg (groin) or chest. The doctor moves the catheter through the blood vessel and into your heart.
The replacement valve fits inside the catheter. The valve is made of tissue and metal. Your doctor will move the new valve into your damaged valve. It will expand and work in place of the old valve.
You may be asleep for the procedure, or you may get a sedative to help you relax. You won't feel pain when the catheter is put in the blood vessel.
You may stay in the hospital for up to a few days.
How do you prepare for the procedure?
Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.
Preparing for the procedure
- You will have several tests to get ready. These may include echocardiograms and a CT scan.
- Be sure you have someone to take you home. Anesthesia and pain medicine will make it unsafe for you to drive or get home on your own.
- Understand exactly what procedure is planned, along with the risks, benefits, and other options.
- If you take aspirin or some other blood thinner, ask your doctor if you should stop taking it before your procedure. Make sure that you understand exactly what your doctor wants you to do. These medicines increase the risk of bleeding.
- Tell your doctor ALL the medicines and natural health products you take. Some may increase the risk of problems during your procedure. Your doctor will tell you if you should stop taking any of them before the procedure and how soon to do it.
- Make sure your doctor and the hospital have a copy of your advance care plan. If you don't have one, you may want to prepare one. It lets others know your health care wishes. It's a good thing to have before any type of surgery or procedure.
What happens on the day of the procedure?
Follow the instructions exactly about when to stop eating and drinking. If you don't, your procedure may be cancelled. If your doctor told you to take your medicines on the day of the procedure, take them with only a sip of water.
Take a bath or shower before you come in for your procedure. Do not apply lotions, perfumes, deodorants, or nail polish.
Take off all jewellery and piercings. And take out contact lenses, if you wear them.
At the hospital or surgery centre
Bring a picture ID.
You will be kept comfortable and safe by your anesthesia provider. The anesthesia may make you sleep. Or you may get medicine that relaxes you or puts you in a light sleep. You won't feel pain when the catheter is put in the blood vessel.
The procedure may take about 2 to 3 hours.
After the procedure, pressure may be applied to the area where the catheter was put in your blood vessel. This will help prevent bleeding. A small device may also be used to close the blood vessel. The area may be covered with a bandage or a compression device.
Nurses will check your heart rate and blood pressure. The nurse will also check the catheter site for bleeding.
If the catheter was put in your groin, you will need to lie still and keep your leg straight for up to a few hours. The nurse may put a weighted bag on your leg.
You may have a bruise or a small lump where the catheter was put in your blood vessel. This is normal and will go away.
When should you call your doctor?
- You have questions or concerns.
- You don't understand how to prepare for your procedure.
- You become ill before the procedure (such as fever, flu, or a cold).
- You need to reschedule or have changed your mind about having the procedure.
