A prosthetic heart valve assembly which includes an artificial annulus, a prosthetic valve and a retaining ring for releasably retaining the prosthetic valve on the artificial annulus. By removing the retaining ring, the valve can be replaced with another valve. The artificial annulus includes a suture ring and a mounting ring mounted on the suture ring for receiving the prosthetic valve and the retaining ring.

An implantable device for removably mounting a prosthetic valve, said implantable device comprising: a fixation ring having an inner periphery defining an opening through the fixation ring and an outer periphery and adapted to be affixed to the natural annulus of a patient; a mounting ring having an inner peripheral surface defining an opening through the mounting ring, said mounting ring being coupled to the fixation ring with said openings being in registry whereby a prosthetic valve can be received in said opening of the mounting ring; a retaining ring separate from the prosthetic valve so that when a prosthetic valve is received in said opening of the mounting ring the prosthetic valve can be angularly oriented independently of the retaining ring; means at least partially on said mounting ring for releasably attaching said retaining ring to the mounting ring so that the retaining ring can retain the prosthetic valve against moving in one direction out of the opening when the prosthetic valve is received in said opening of the mounting ring and the retaining ring can be removed to permit replacement of the prosthetic valve with another prosthetic valve; means for use in retaining the prosthetic valve against moving in another direction out of the opening in the mounting ring when the prosthetic valve is received in said opening of the mounting ring; and said retaining ring is annular, has an axis and is thin in the direction of said axis.
