Transcatheter aortic valve replacement (TAVI)
What is a transcatheter aortic valve replacement (TAVI)?
Typically conducted under local anaesthesia, transcatheter aortic valve implantation (TAVI) is a minimally invasive procedure whereby a new valve is inserted without removing the old, damaged valve.
The TAVI approach delivers a fully expandable replacement valve to the valve site through a catheter. Once the new valve is expanded, it pushes the old valve leaflets out of the way and the tissue in the replacement valve takes over the job of regulating blood flow.
Compared to surgical replacement it is less invasive, is generally performed under local anaesthesia and does not require cardiopulmonary bypass. Furthermore, TAVI results in a shorter hospital stay and a faster recovery.
Some patients unsuitable for surgery may now be treated using TAVI.
In addition, the incidence of death or stroke is 1-2 percent which is lower than conventional surgery.
