    Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve assembly. In embodiments, a prosthetic heart valve assembly, including a self-expandable support structure and a self-expanding heart valve, are advanced through the aortic arch of a patient using a delivery system. The support structure, which includes a plurality leaflet retaining arms, is at least partially expanded and positioned on or adjacent to the outflow side of the aortic valve. The prosthetic heart valve is positioned in the aortic valve. The prosthetic heart valve is expanded while it is within an interior of the support structure and while the support structure is positioned on or adjacent to the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the arms of the support structure and the expanded prosthetic heart valve.

    Abstract: Prosthetic heart valve assemblies and methods, apparatus, and systems used to deliver a prosthetic heart valve assembly. A prosthetic heart valve assembly includes an inner frame, a prosthetic leaflet section disposed within the inner frame extending between in inflow row of cells and an outflow row of cells of the inner frame, and an outer support stent. The inner frame is disposed within the outer support stent, and the outer support stent is coupled and/or fastened to the inner frame. The outer support stent includes a plurality leaflet capturing arms for capturing native leaflets between the leaflet capturing arms and a portion of the prosthetic heart valve assembly when the prosthetic heart valve assembly is implanted in a native valve. For example, the native leaflets can be frictionally secured between the leaflet capturing arms of the support stent and the inner frame.

    Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support structure and an expandable prosthetic valve are advanced through the aortic arch of a patient using a delivery system. The support structure is delivered to a position on or adjacent to the surface of the outflow side of the aortic valve (the support structure defining a support-structure interior). The expandable prosthetic valve is delivered into the aortic valve and into the support-structure interior. The expandable prosthetic heart valve is expanded while the expandable prosthetic heart valve is in the support-structure interior and while the support structure is at the position on or adjacent to the surface of the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the support structure and the expanded prosthetic heart valve.
