Transcatheter Aortic Valve Implantation (TAVI) or (TAVR)

TAVI or TAVR involves implanting new aortic valve via a less invasive technique than open- heart surgery. This is performed mostly when there is severe narrowing of the aortic valve called aortic stenosis. In this procedure the new valve is inserted through a catheter (thin tube) into the heart, with the patient under general anaesthesia or using local anaesthesia with sedation. The new valve is positioned within the existing aortic valve under x-ray guidance. The catheter is normally inserted into the body through a large blood vessel, usually in the groin (known as the transfemoral approach). Sometimes the valve is inserted directly into the heart through a small cut in the chest (known as the transapical approach). The inserted valve will stay in position as in surgical procedure without the sutures. The patient can be discharged home in 1-2 days and the recovery from this procedure is much quicker than the open-heart surgical procedure.
