In accordance with one embodiment of the present disclosure, a prosthetic valve is provided. The prosthetic valve includes an annulus, a pair of leaflets, and a pair of support elements. The annulus has a generally saddle-shape formed by a movable pair of first portions separated from each other by a movable pair of second portions. The pair of leaflets extend from the annulus and are separated from each other by the pair of support elements. The first portions of the annulus and the second portions of the annulus are configured to move back and forth from being generally concave to being generally convex such that any movement of the first portions of the annulus occurs at generally the same time as any movement of the second portions of the annulus.
