Abstract
Exemplary embodiments provide a valve prosthesis for deployment at an annulus of a heart valve. The valve prosthesis includes a series of connected loops that form a looped structure for placement in the annulus. The loops include a first set of fastening mechanisms that extends radially outward over the annular ring and fasten the valve prosthesis to the atrium. The loops also include a second set of fastening mechanisms that extends radially outward at the annular ring and fasten the valve prosthesis to the annular ring. The loops optionally include a third set of fastening mechanisms that extends radially outward under the annular ring and fasten the valve prosthesis to the ventricle.
