Abstract
A heart valve assembly includes an annular prosthesis and a plurality of guide shields removably attached around a circumference of the annular prosthesis. A plurality of elongate guide rails extend from the annular prosthesis, which are releasably retained by the guide shields. During use, the annular prosthesis is directed into a biological annulus, e.g., with the guide rails retained by the guide shields, and secured to tissue surrounding the biological annulus using fasteners. The guide rails are released from the guide shields, and a valve prosthesis is advanced over the leaders and through a passage defined by the guide shields towards the annular prosthesis. The guide rails may include retentions elements that secure the valve prosthesis to the annular prosthesis. The guide shields are removed from the annular prosthesis, the guide rails are separated from the annular prosthesis, and are removed from the biological annulus.
