1. A prosthetic valve comprising:
a leaflet frame subcomponent including a leaflet frame and having an inflow end and an outflow end;
an anchor frame subcomponent including an anchor frame and having an inflow end and an outflow end,
the anchor frame subcomponent being coupled to the leaflet frame subcomponent such that the prosthetic valve is configured to be transitioned from a delivery configuration in which the leaflet frame subcomponent and the anchor frame subcomponent are longitudinally offset from one another such that the inflow end of the leaflet frame subcomponent is situated distal of the outflow end of the anchor frame subcomponent to a deployed configuration in which the leaflet frame subcomponent is at least partially nested at a nested position within the anchor frame subcomponent such that the leaflet frame subcomponent and the anchor frame subcomponent define a pair of adjacent inflow end portions, a pair of adjacent outflow end portions, and an annular gap that includes an outflow annular groove between the leaflet frame subcomponent and the anchor frame subcomponent; and
an outflow annular groove cover extending between the pair of adjacent outflow end portions to cover the outflow annular groove between the leaflet frame subcomponent and the anchor frame subcomponent when the prosthetic valve is in the deployed configuration.
