Title: (EN) PROSTHETIC HEART VALVE STRUCTURES AND RELATED METHODS
(FR) STRUCTURE DE VALVULE CARDIAQUE PROSTHETIQUE, ET PROCEDES ASSOCIES
Abstract:
(EN) A prosthetic heart valve includes a valve core (20) and a mounting retainer (39) that extends radially out from the core to an outer perimeter portion (40). The outer perimeter portion has a different shape than a perimeter of 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 valve is in use in a patient. The outer perimeter portion is used to mount the valve to another structure such as a native valve annulus in a valve replacement procedure. The mounting retainer bridges the gap(s) between the valve core and the outer perimeter portion, and may also provide attachment sites for other native tissue structures (like chordae tendonae), which attachment sites can be at or at least closer to original (native) attachment sites for those tissue structures.
