A dual member stent-valve for transcatheter delivery to a native heart valve needing replacement. A first component is attached to the native annulus upstream of the native leaflets maintaining native leaflet function, and is held to the native annulus by barbs that are activated by a torus balloon after the first component is fully expanded. The torus balloon can be implanted along with the support frame. A limiting cable restricts further expansion of the first component and holds a second component that contains the replacement leaflets.
