Cardiovascular system Transcatheter Aortic Valve Implantation

The aortic valve implantation by catheter can be done by two routes: transfemoral or transapical.

In the transfemoral route, the whole procedure is performed by the groin, with the valve being implanted by catheters, which navigate inside the arterial system, from the femoral artery to the heart. The diseased valve is dilated by a balloon and the prosthesis is implanted. The procedure is less invasive than the conventional surgery.
