1. An assembly comprising:
a holder device; and
a non-self-expandable prosthetic heart valve being radially compressible from an expanded configuration to a compressed configuration, the prosthetic heart valve comprising an annular frame that is radially compressible and expandable;
wherein the holder device is configured to hold the prosthetic heart valve in the expanded configuration and to allow the prosthetic heart valve to be inserted in a crimping device so that the prosthetic heart valve can be crimped onto a valve mounting portion of a delivery apparatus,
wherein the holder device comprises one or more retaining members configured to secure the prosthetic heart valve to the holder device when the prosthetic heart valve is in the expanded configuration and release the prosthetic heart valve from the holder device when the prosthetic heart valve is compressed from the expanded configuration to the compressed configuration on the valve mounting portion of the delivery apparatus,
wherein each retaining member comprises an axially extending beam and a protrusion extending radially outwardly from a distal end portion of the beam, wherein the beam extends distally into an interior space of the annular frame when the prosthetic heart valve is in the expanded configuration,
wherein the protrusion extends radially from the interior space of the annular frame, through an open cell of the annular frame, to a location outside of the annular frame when the prosthetic heart valve is in the expanded configuration.
