The elongate frame can be configured to move between a radially compacted state and a radially expanded state, the frame comprising a plurality of struts. Stitches attach the valve body to the plurality of struts. At least one of the stitches can be a loose stitch configured to freely slide over the corresponding strut when the frame is moved between the radially compacted and radially expanded states.
