Abstract
A method for treating a stenotic native aortic valve in a human heart is provided. The method comprises dilating the stenotic native aortic valve using a dilatation catheter and then deploying a prosthetic heart valve within the dilated stenotic native aortic valve. The prosthetic heart valve comprises a collapsible and expandable metallic stent and a valvular structure formed of a synthetic biocompatible material. The valvular structure is positioned substantially between the inlet and outlet ends of the stent for preventing the flow of blood in one direction. The prosthetic heart valve may further comprise an internal sleeve for creating a seal along at least a portion of the stent wall.
