Transcatheter Aortic Valve Implantation (TAVI)

A Transcatheter Aortic Valve Implantation (TAVI) is a procedure to replace your heart valve.  ‘Transcatheter’ means a catheter (small tube) is inserted either via a transfemoral route, or transapical route.  The transfemoral route involves a small puncture in the blood vessel in your groin, threading a tube and the new valve into the heart, whereas the transapical route involves a small cut made in your chest in between your ribs.  Your aortic valve may need to be replaced due to aortic stenosis.  The aortic valve directs blood flow leaving the heart, however, stenosis may narrow this valve, not allowing blood to optimally flow out causing chest pain, shortness of breath and tiredness and fainting symptoms.  The TAVI procedure is a safer method than open heart surgery for at risk individuals (kidney or lung disease, previous chest radiation, prior open heart surgeries etc.).

Description

Pre Test Procedures

  1. You will have a 3-4 hour visit with a doctor and nurses in the CPAC prior to your procedure.
  2. Once entering the Pre/Post Procedure area, you will change into a hospital gown.  It is suggested you give your belongings to your family to hold onto until after your TAVI.  Your family will be allowed to visit you here.
  3. The nurse will ask you a few questions and help you onto a stretcher.
  4. An intravenous will be started, and your groin area will be shaved and washed.
  5. You will be given special mouth wash to prevent infection.
  6. Before the TAVI, the doctor will review both the benefits and risks of the TAVI and have you read and sign a consent form agreeing to the TAVI procedure.

Test Procedures – 2 -3 hours 

  1. You will be transferred to the TAVI room.
  2. The anesthesiologist will give you medications to keep you relaxed and pain-free.  Some patients need a general anesthetic and breathing tube.  We will tell you if you will need either before starting your TAVI.
  3. During the TAVI, your family is welcome to wait in the Y2 waiting room.  The doctor will come to speak to your family when the TAVI is complete.  

Post Test Procedures

Recovery in Intensive Care

  1. You will be transferred to the Pre/Post Procedure area, and in some cases, the Intensive Care Cardiac Surgery (ICCS) or the Acute Cardiac Care Unit (ACCU).  
  2. For the first four hours after the TAVI, a nurse will be checking your insertion site in your groin often and the head of your bed must be kept relatively flat.  The nurse will check you often.  Notify them of pain or discomfort.
  3. Your leg must be kept straight for the first four hours after the TAVI to prevent bleeding.
  4. When safe to do so, we will help you move around.  You will progress from sitting on the bed, to getting into a chair, and then walking in the hall. 
  5. You will be given clear fluids initially, followed by increasing to your normal diet as drinking becomes normal.
  6. The special monitoring equipment will be removed when you are ready to be transferred to the ward.

Recovery on the Ward

  1. When you are ready, you will be transferred to Cardiology on the A Block, 5th floor of the main hospital, or to the Cardiac Surgery Inpatient Unit (CSIU) on the 4th floor of the Asper Centre.
  2. While in the ward you will have some restrictions:
    • Do not lift, push or pull anything greater than 5 pounds for the first five days
    • Do not bend at the hips or sit for long periods of time (including bowel movements)
    • You will wear a heart monitor for 24-48 hours or until you are discharged home
    • Blood tests, chest X-rays, and other heart tests will be done as needed
    • The nurse will check your insertion sites often. You will learn what to watch for while your sites heal and we will teach you how to care for your sites at home
    • Notify the nurse or doctor if you notice the following: Bleeding from the site, a lump that is getting bigger, any area of redness or warmth that does not get better, yellow drainage from the insertion site, numbness in your leg, severe pain at the insertion site, or confusion, blurry vision or weakness
