TAVI is a technique for treating severe aortic stenosis in patients that cannot tolerate surgery. Aortic stenosis is the pathology in which a person's aortic valve does not open and close correctly, causing tiredness, chest pains and dizziness.

How does it work? Through a catheter that can be introduced into the patient's groin through the femoral artery or via a transapical approach (through an incision through the lower point of the left ventricle) the damaged aortic valve is changed for a new one without having to carry out open surgery.

By avoiding open surgery, the related complications are reduced, avoiding lengthy stays in the ICU.
