Abstract

A prosthetic heart valve for replacement of a native heart valve having a native valve annulus includes a stent body having a proximal end adjacent an inflow end and a distal end adjacent an outflow end and including an annulus section, the stent body having a radially collapsed condition and a radially expanded condition, one or more prosthetic valve elements mounted to the stent body and operative to allow flow in an antegrade direction from the inflow end to the outflow end but to substantially block flow in a retrograde direction from the outflow end to the inflow end, a cuff coupled to the stent body, the cuff having a mobile portion that is moveable relative to the stent body, and at least one engagement element remote from the stent body.
