A collapsible and expandable prosthetic mitral valve stent is provided with improved recapture into a distal lumen of a delivery sheath. Various embodiments comprise a valve support within the interior of a stent frame and defining a flow channel therethrough, wherein the top or upstream of the valve support comprises a row, or a plurality, of stent cells that are bent radially inward at least partially over the flow channel. Some embodiments may comprise a recapture assist mechanism, such as an open paddle, attached to one or more of the inwardly bent stent cells and adapted to receive and/or engage a wire to aid in positioning, expansion, recapture and/or implanting the device in a patient's heart chamber.
