Valve TAVI

Transcatheter Aortic Valve Implantation (TAVI) is a minimally invasive procedure that involves implanting an aortic valve using a slender tube known as a catheter. Typically, the catheter is introduced either through a large blood vessel in the groin or through a small incision in the chest.

Specially crafted transcatheter aortic valves are employed for this procedure. These valves are constructed from natural tissue sourced from the hearts of cows or pigs. The natural tissue undergoes a re-engineering process and is affixed to a flexible expanding mesh frame. To facilitate its insertion into the heart, the valve is compressed around or within a catheter. Subsequently, the catheter is carefully guided to the aortic valve opening in the heart, where it is implanted over the existing valve. Once the new valve is in place, the catheter is removed, and the newly implanted valve begins functioning immediately.
