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

  • positioning an expandable first stent adjacent the native aortic valve, a proximal-most end of the first stent including a plurality of struts, wherein a proximal end of the first stent is closer to a native heart than a distal end of the first stent;

    expanding the plurality of struts of the first stent;

    after expanding the plurality of struts, positioning the plurality of struts between a wall of an aorta and portions of the native aortic valve, wherein the plurality of struts align the first stent with the native aortic valve in an axial direction;

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

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