In some examples, a prosthetic heart valve for implantation within a native heart valve includes a radially expandable frame and a valve structure. The frame includes an annular body having an inflow end and an outflow end. The body is radially expandable between a radially compressed state and a radially expanded state. The valve structure includes a plurality of leaflets disposed within and coupled to a frame. The frame includes a plurality of frame anchors coupled to the body. Each frame anchor is configured to be positioned on or around a pair of free edges of two of the native leaflets of the native heart valve. In some examples, a prosthetic heart valve delivery assembly includes a prosthetic heart valve and a delivery device for delivering the prosthetic heart valve to an implantation site. 在一些实例中，一种用于植入天然心脏瓣膜内的假体心脏瓣膜包括可径向扩展的框架和瓣膜结构。框架包括具有流入端和流出端的环形主体。主体可在径向压缩状态与径向扩展状态之间径向扩展。瓣膜结构包括多个瓣叶，所述多个瓣叶设置在框架内并且联接到该框架。框架包括联接到主体的多个框架锚固件。每个框架锚固件构造成定位在天然心脏瓣膜的天然瓣叶中的两个天然瓣叶的一对自由边缘上或围绕所述一对自由边缘定位。在一些实例中，一种假体心脏瓣膜递送组件包括假体心脏
