1. A method of treating a native aortic valve, the method comprising:

  • positioning a first expandable stent component adjacent the native aortic valve, the first stent component including three struts, wherein the three struts include exactly one strut for placement between each leaflet of the native aortic valve and a wall of an aorta, wherein each strut includes an apex pointing in a proximal direction towards a native heart;

    expanding the struts of the first stent component;

    after expanding the struts, positioning each strut between the respective leaflet and the wall of the aorta, wherein the struts align the first stent component with the native aortic valve in an axial direction;

    positioning a second expandable stent component radially inward of the leaflets of the native aortic valve and of the first stent component, wherein the second stent component includes a prosthetic heart valve; and

    expanding the second stent component to press the leaflets of the native aortic valve radially outward toward the first stent component, such that the leaflets of the native aortic valve are positioned between the first stent component and the second stent component.
