A prosthetic heart valve includes a valve core (20) and a mounting retain er (39) that extends radially out from the core to an outer perimeter portio n (40). The outer perimeter portion has a different shape than a perimeter o f the valve core when both perimeters are viewed along an axis that will be the axis of blood flow through the valve core when the prosthetic heart valv e is in use in a patient. The outer perimeter portion is used to mount the v alve to another structure such as a native valve annulus in a valve replacem ent procedure. The mounting retainer bridges the gap(s) between the valve co re and the outer perimeter portion, and may also provide attachment sites fo r other native tissue structures (like chordae tendonae), which attachment s ites can be at or at least closer to original (native) attachment sites for those tissue structures. |
