A replacement heart valve implant defining a central longitudinal axis extending from an upstream end to a downstream end may include an expandable anchor member configured to shift between a delivery configuration and a deployed configuration, a circumferential support member distinct from and attached to the expandable anchor member, at least a portion of the circumferential support member extending downstream of the expandable anchor member, and a plurality of valve leaflets secured to the expandable anchor member. The plurality of valve leaflets may include a valve leaflet commissure movable from a first longitudinal position relative to the downstream end in the delivery configuration to a second longitudinal position relative to the downstream end in the deployed configuration.
