Abstract: An assembly including a transcatheter valve prosthesis and a leaflet folding accessory configured for use when compressing the transcatheter valve prosthesis into the crimped configuration. The transcatheter valve prosthesis includes a frame and a prosthetic valve component including at least one leaflet disposed within and secured to the frame. The leaflet folding accessory includes a plurality of guide fingers. A leaflet contact portion of each guide finger is configured to be disposed radially within the frame and contact an inner surface of a leaflet of the at least one leaflet. During crimping of the transcatheter valve prosthesis, the plurality of guide fingers remain disposed radially within the frame such that the at least one leaflet preferentially folds around the plurality of guide fingers.
