A heart valve prosthesis comprising an annular support frame for a plurality of flexible tissue valve components. The support frame has a plurality of spaced posts defining openings therebetween to permit a portion of each valve element to flex from an open position to a closed position. An annular sleeve, concentric with said support frame, is adapted to clamp a non-flexing portion of each valve element in operative position between the support frame and said sleeve.
