Abstract
A method of implanting a prosthetic valve in a stenosed aortic valve via a catheterization technique. A balloon catheter is advanced into a patient's vasculature and a balloon is expanded within the stenosed aortic valve to push aside the calcified leaflets. The prosthetic valve is then introduced into a patient's vasculature through an 18 French arterial introducer. After advancement through the femoral artery and aorta, the prosthetic valve is radially expanded for implantation in the dilated aortic valve. The prosthetic valve includes a compressible and expandable frame and a valvular structure made with pericardial tissue. The prosthetic valve further includes an internal cover fastened to an internal surface of the frame between an inlet end of the frame and the valvular structure.
