Beschreibung
Zusammenfassung:	An armature (1) for a prosthetic heart valve (13), extended along a longitudinal axis (x) and radially expandable and collapsible, comprises a body (9) which includes an annular element (10), supporting the prosthetic valve (13), an anchoring frame (12), which is inserted into a cavity in a patient's heart, and a plurality of radial formations (14), radially spreadable with respect to the body (9) to hold the flaps (15) of the native valve in open position, where the armature (1) is configured in such a way as to avoid anchoring to the annulus of a native heart valve. Armature (1) pour une prothèse valvulaire cardiaque (13), se prolongeant le long d'un axe longitudinal (x) et radialement extensible et repliable, comprenant un corps (9) qui comprend un élément annulaire (10), supportant la valvule prothétique (13), une structure d'ancrage (12), qui est insérée dans une cavité du cœur d'un patient, et une pluralité de formations radiales (14), déployables radialement par rapport au corps (9) pour maintenir les lambeaux (15) de la valvule native en position ouverte, l'armature (1) étant conçue de manière à éviter un ancrage à l'anneau d'une valvule cardiaque native.
