Transcatheter Aortic Valve Implantation (TAVI)
Transcatheter Aortic Valve Implantation (TAVI) is an invasive treatment that can be used to replace one or more of the aortic valves in the body. The treatment is used for patients with either severe heart failure (HF) or for those who have had cardiac surgery and had a valve left open. The procedure is performed by inserting the upper end of a balloon catheter into the groin. The catheter is inflated and then positioned through the opening of the aortic valve so that its external side faces the groin. Percutaneous and ultrasonic transcatheter aortic valve implantation (TAVI) is one of the more common procedures performed today. This type of surgery is also referred to as Transcatheter Aortic Valve Implantation (TAVI). The procedure involves the insertion of an artificial valve into the heart.
The valve is then surgically attached to the opening of the heart where the aorta originates. The mechanical properties of these valves make them ideal for conducting cardiac waves. They can be made from a variety of materials including plastic, metal, or even ceramics. They can have either one or two faces. Face one is often used for compression while facing two is used for repositioning. The surface may be smooth or textured. The valve is used to limit and isolate the outflow of blood from the heart. It does this by varying the pressures that are applied to the walls of the valve. As the pressure varies, the valve opens and provides an opening to the heart.
