Claim:
1. A prosthetic aortic valve system for replacing a native aortic valve, the native aortic valve comprising an aortic valve annulus, a plurality of native leaflets, a plurality of valve commissures, an inflow side, and an outflow side within an aorta, the prosthetic aortic valve system comprising a support structure, a transcatheter heart valve, and a balloon catheter: the support structure comprising a radially collapsible and self-expanding, nitinol annular body and a plurality of retaining arms extending from the annular body, the annular body comprising an interior surface, an exterior surface, and three peaks and three valleys in a z-direction, an expanded size of the annular body dimensioned for deployment within the aorta on the outflow side of the native aortic valve with the interior surface circumscribing the native leaflets and the three peaks oriented adjacent to the valve commissures, the retaining arms extending from the annular body to a support structure delivery system and forming a releasable connection with the support-structure delivery system, the support structure radially collapsible to a diameter suitable for delivery using the support-structure delivery system; and the transcatheter heart valve radially compressible to a compressed size suitable for delivery using the balloon catheter and radially balloon-expandable from the compressed size to a fully expanded size, wherein the expanded size of the annular body is equal to or less than the fully expanded size of the transcatheter heart valve for frictionally engaging the native leaflets between the interior surface of the annular body and the transcatheter heart valve when the support structure is deployed within the aorta on the outflow side of the native aortic valve with the interior surface of the annular body circumscribing the native leaflets and the transcatheter heart valve is expanded within the aortic valve annulus, wherein the support structure is deliverable separately from the transcatheter heart valve, further wherein the support structure is positionable and repositionable adjacent the aortic valve annulus independent of the transcatheter heart valve when the annular body is in the fully expanded size; and the balloon catheter comprises an elongate catheter and an expansion balloon disposed at a distal end-portion thereof, wherein the transcatheter heart valve is mounted on the expandable balloon in the radially compressed configuration.
