1. A method of implanting a prosthetic heart valve system at an aortic heart valve annulus, comprising:

  • advancing a base stent to an implant position adjacent an aortic heart valve annulus;

    radially expanding the base stent so as to anchor the base stent to the aortic heart valve annulus, the expanded base stent having an outflow end portion and an inflow end portion, at least a portion of the outflow end portion having a three-lobed cross-sectional profile with three outwardly-projecting lobes intermediate three regions of lesser radial dimension;

    providing a prosthetic valve having a support frame surrounding an orifice including a non-expandable, non-collapsible valve stent coupled to leaflets that coapt within the orifice and form the occluding surfaces of the prosthetic valve, the prosthetic valve further having a coupling stent connected to and extending from an inflow end of the valve stent;

    advancing the prosthetic valve into the outflow end portion of the base stent; and

    radially expanding the coupling stent to an expanded state so as to anchor the prosthetic valve to the base stent.
