Transcatheter Aortic Valve Replacement (TAVR)

For people who have been diagnosed with severe aortic stenosis and who are high-risk or too sick for open heart surgery, TAVR may be an option. TAVR can result in lengthening patients’ lives. This less invasive procedure allows a new valve to be inserted within your diseased aortic valve.  For TAVR procedures, Boone Hospital Center surgeons utilize the Edwards SAPIEN 3 transcatheter heart valve.

The TAVR Procedure

TAVR allows a new valve to be inserted through a catheter. The total procedure time varies from about 1 to 2 hours.

  1. In preparation for your procedure, you will be placed under anesthesia (you will be in a deep sleep).
  2. Your doctor will make an incision in your leg. A short, hollow tube called a sheath will be placed into the incision. This will allow your doctor to put various devices through the sheath to access your heart. 
  3. Your new valve will be placed on a delivery system—a tube with a balloon on the end. The valve will be compressed on the balloon to make it small enough to fit through the sheath. The delivery system and compressed valve will be inserted into the sheath.
  4. Once the delivery system reaches your diseased valve, the balloon will be inflated with fluid, expanding the new valve into place. The valve will push the leaflets of your diseased valve aside. The frame of the new valve will use the diseased valve leaflets to secure itself in place.
  5. The balloon will then be deflated and removed. Your doctor will ensure the new valve is working properly before closing up the incision site.

What Happens After the Procedure?

Your heart team will determine your immediate after-care plan. Your heart team will give you specific instructions to help you with your recovery. This may include a special diet, exercise, and medicine. It is important to carefully follow your doctor’s directions, especially if blood-thinning drugs are prescribed. You will be expected to attend regular check-ups. Regular check-ups with your doctor are very important. Call or see your doctor whenever you have questions or concerns about your health. If you experience any unusual problems such as bleeding, pain, other discomfort, or changes in your overall health, be sure to contact your doctor.
