Abstract
A heart valve prosthesis includes a frame and a prosthetic disposed within a lumen of the frame. The frame includes a plurality of struts and crowns and has a radially collapsed state and a radially expanded state. A stiffness of the plurality of struts is varied by varying the width of at least one strut of the plurality of struts such that when the frame is in the radially expanded state, the frame has a substantially elliptical shape.
