The invention relates to an expandable prosthetic heart valve. The present disclosure relates to a prosthetic heart valve with an expansion and locking assembly. As one example, a prosthetic heart valve may include an annular frame and an expansion and locking assembly configured to radially expand the frame to a radially expanded state and/or lock the prosthetic valve in the radially expanded state to prevent collapse (i.e., radial compression) of the prosthetic valve. In some examples, a prosthetic heart valve may be configured to radially self-expand to a partially radially expanded state, and then may be further radially expanded to and/or locked in a radially expanded state by pulling an actuator member of an expansion and locking assembly. In some examples, the actuator member may extend through an opening in a vertical strut of the frame. 本申请题为"可扩展的假体心脏瓣膜"。本公开涉及具有扩展和锁定组件的假体心脏瓣膜。作为一个示例，一种假体心脏瓣膜可以包括环形框架以及扩展和锁定组件，该扩展和锁定组件被配置为将框架径向扩展到径向扩展状态和/或将假体瓣膜锁定在径向扩展状态以防止假体瓣膜塌缩(即径向压缩)。在一些示例中，假体心脏瓣膜可以被配置为径向自扩展到部分径向扩展状态
