    Abstract: A prosthetic heart valve may include a stent having an inflow end, an outflow end, a collapsed condition, and an expanded condition. The prosthetic valve may also include a collapsible and expandable valve assembly disposed within the stent and having a plurality of leaflets. The prosthetic valve and/or stent may include features to anchor the prosthetic valve to a native valve annulus and to seal the prosthetic valve with respect to the native valve annulus, such as planar and/or nonplanar annular sealing members coupled to ends of the stent. The stent may include one or more circumferential rows of anchor members or hooks extending radially outwardly from the stent. These hooks may be configured to extend in a particular direction when the stent is in the collapsed condition to facilitate resheathing of the stent if, upon deployment, a user determines the prosthetic heart valve is not positioned optimally.

    Abstract: A prosthetic mitral valve includes a collapsible and expandable elliptical or “D”-shaped stent. The stent includes first and second commissure attachment features and a collapsible and expandable valve assembly disposed therein. The valve assembly includes two leaflets, each leaflet having a first edge operably coupled to the stent and a second free edge. Each leaflet may include first and second tabs connecting first and second ends of the first and second edges, respectively. Each leaflet includes a height measured from a midpoint of the first edge to a midpoint of the second edge and a width measured from a junction of the first edge with the first tab to a junction of the first edge with the second tab. The ratio of the height to the width may be between about 0.4 and about 0.65.
