An apparatus for stabilizing a prosthetic heart valve within an atrioventricular valve includes a collapsible and expandable stent having an inflow end, an outflow end, and struts forming a plurality of cells connected to one another in a plurality of annular rows around the stent. The stent further includes a collapsible and expandable valve assembly secured to the stent. The valve assembly includes a cuff and a plurality of leaflets having an open configuration and a closed configuration.
