Beschreibung
Zusammenfassung:	A heart valve stent and a prosthetic heart valve structure thereof. Wherein, the heart valve stent comprises a stent body (1); a joint member (2) comprising a fixed part and an elastic stretching part connected to the fixed part, an end of the elastic stretching part away from the fixed part is a movable end. By means of optimal design of the stent structure, the service life of a prosthetic heart valve mounted on the stent is prolonged, and meanwhile, a material with lower elasticity can be used to achieve a valve performance comparable to that achieved by a material with higher elasticity in the prior art; moreover, a leaflet assembly (31) is enabled to close more quickly with less external force, which has significant effects.
