Open heart Surgery or TAVI

Open heart surgery and TAVI are both standard treatments for aortic stenosis.1

Open heart surgery is an invasive procedure and can lead to serious complications.2

TAVI is a less invasive alternative to surgery.3

It is available to all patients with severe aortic stenosis, including those who are advised to not undergo surgery.4

See here for more details on both procedures.

What happens during the TAVI procedure

Your TAVI procedure will be performed in an operating room at a hospital.

  • You will be injected with a suitable sedative to prevent any pain during the procedure.1,3
  • You may be given medications to prevent blood clots or reduce the risk of infection.5

How is TAVI done?1


A small incision will be made on your upper leg* to insert a thin tube which can reach your heart.

*TAVI can be performed through other approaches as well.


The new valve will be placed inside the tube with an expandable balloon at the end (balloon-expandable valve), and pushed towards your aortic valve.

Once the tube reaches your aortic valve, the balloon will be expanded and the new valve will be put into place.


Your doctor will make sure your new valve is working properly before closing the incision on your leg.
