If your aortic valve is severely narrowed, you may require replacement of your valve. For some patients an open heart surgical operation may be too high risk for you. In this case you maybe eligible for a 'key hole' procedure which is called Transcatheter Aortic Valve Implantation (TAVI).
TAVI is an alternative to open heart surgery and is considered a minimally invasive approach. During the procedure a new replacement valve is crimped onto a delivery catheter which is inserted from a small incision at the top of the leg. Once in the heart, the valve is positioned and deployed across the patients diseased aortic valve. Generally patients remain in hospital for a few days after the procedure and the rehabilitation process is much quicker than compared to open heart surgery.
