Abstract
A transcatheter heart valve prosthesis configured in accordance herewith includes an expandable frame having a plurality of commissure posts extending therefrom, a radially expandable inflow member attached to the plurality of commissure posts, and a locking mechanism operably coupled to a wire. The wire is at least partially slideably disposed within a channel formed in a wall of the inflow member and the locking mechanism is configured to permit the wire to be advanced within the channel to thereby transition the inflow member into a deployed configuration that at least partially engages tissue at the native heart valve.
