Beschreibung
Zusammenfassung:	A prosthetic heart valve comprises a radially expandable frame comprising an outflow end and an inflow end, and a plurality of valve leaflets disposed within and coupled to the frame. Each leaflet comprises a main body having an outflow edge portion and an inflow edge portion, wherein the leaflets are configured to move between an open state and a closed state in which the outflow edge portions coapt with each other and block the flow of blood through the frame from the outlet end to the inlet end, wherein the inflow edge portion of each leaflet includes a movable portion that can move radially inwardly when the leaflets move to the closed state to assist with the coaptation of the outflow edge portions of the leaflets and radially outwardly when the leaflets move to the open state.
