Abstract
In some embodiments, a valve prosthesis includes an inlet portion that is substantially s-shaped and configured to engage the floor of the outflow tract of the native heart atrium. In some embodiments, a valve prosthesis includes a chordae guiding element configured to reduce bending of the chordae to reduce stress on the chordae during the cardiac cycle. In some embodiments, a valve prosthesis includes a central portion having an hourglass shape configured to pinch a native annulus in order to provide axial fixation of the valve prosthesis within a valve site. In some embodiments, a valve prosthesis includes a frame having an outflow end that is flared to provide a gap between an outflow end of the frame and an outflow end of prosthetic leaflets when the prosthetic leaflets are fully opened.

29. A valve prosthesis comprising:
-
a frame including a central portion, a support member extending from the central portion, the support member having an engagement portion configured to engage and tension at least one native chorda to thereby restrict movement of the valve prosthesis in an upstream direction of blood flow, and an inlet portion extending radially outward from the central portion and configured to engage a floor of an outflow tract of a native heart atrium to thereby restrict movement of the valve prosthesis in a downstream direction of blood flow; and a prosthetic valve secured to the central portion. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
