TAVI (transcatheter aortic valve implantation)

Specialty of Cardiothoracic surgery

Transcatheter aortic valve implantation (TAVI) (known as transcatheter aortic valve replacement or TAVR in the USA) is a modern innovative surgical technique to replace the aortic valve. The aortic valve opens when the heart pumps blood, but if it cannot open or close properly the heart is put under strain. For patients who cannot undergo open-heart surgery, TAVI allows surgeons to implant a specially designed aortic valve using a catheter (a long, narrow tube), which is inserted via a large blood vessel (often in the groin).
