A prosthetic heart valve (2) comprising a mounting ring (4) of suturable material for suturing into an annulus (6) in the heart, a valve ring (10) carried by said mounting ring and a moveable valve member (12) carried by said valve ring. The mounting ring (4) includes a clamping member (20) clamping said valve ring thereto, said clamping member being operable to release said valve ring and its valve member so as to allow replacement thereof while leaving the mounting ring (4) sutured in the heart. The removable and remplacement of the valve ring (10) is affected by an instrument (30) specifically adapted for use with the prosthetic heart valve. The instrument (30) includes a rod (40) with a first jaw (42) and a slide (48) with a second jaw (50). |
