A prosthetic heart valve for replacing a native valve, comprising: a stent configured to have a collapsed condition and an expanded condition, the stent extending from a proximal end to a distal end, the stent comprising an annulus section adjacent the proximal end and an aortic section adjacent the distal end, the stent having a luminal surface and an abluminal surface extending between the distal end and the proximal end thereof, and the stent comprising a plurality of runners, a first group of the runners being located at a mid-joint or mid-peak of the stent and a second group of the runners being located between the first group of runners and the proximal end of the stent; a cuff disposed on the luminal surface of the stent and covering all or a part of the annulus section; a panel of sealing material, the panel having a distal end attached to the second group of runners and a proximal end not attached to the stent, the panel having a first orientation at least partially disposed at a first position on the abluminal surface of the stent and a second orientation at least partially disposed at a second position on the abluminal surface of the stent different from the first position, the proximal end of the panel terminating adjacent the proximal end of the stent in the first orientation; a valve assembly disposed within the stent, the valve assembly including a plurality of leaflets; and a plurality of elongated members each having a distal end coupled to a respective one of the first group of runners between the cuff and the stent and a proximal end overlying the abluminal surface adjacent the proximal end of the stent and coupled to the proximal end of the panel at circumferentially spaced apart locations, the plurality of elongated members having a tensioned state when the panel is arranged in the first orientation and a relaxed state when the panel is arranged in the second orientation, the panel folding back upon itself toward the distal end of the stent to move from the first orientation to the second orientation when the plurality of elongated members move from the tensioned state to the relaxed state to create a bunched-up ring of sealing material. a stent configured to have a collapsed condition and an expanded condition, the stent extending from a proximal end to a distal end, the stent comprising an annulus section adjacent the proximal end and an aortic section adjacent the distal end, the stent having a luminal surface and an abluminal surface extending between the distal end and the proximal end thereof, and the stent comprising a plurality of runners, a first group of the runners being located at a mid-joint or mid-peak of the stent and a second group of the runners being located between the first group of runners and the proximal end of the stent; a cuff disposed on the luminal surface of the stent and covering all or a part of the annulus section; a panel of sealing material, the panel having a distal end attached to the second group of runners and a proximal end not attached to the stent, the panel having a first orientation at least partially disposed at a first position on the abluminal surface of the stent and a second orientation at least partially disposed at a second position on the abluminal surface of the stent different from the first position, the proximal end of the panel terminating adjacent the proximal end of the stent in the first orientation; a valve assembly disposed within the stent, the valve assembly including a plurality of leaflets; and a plurality of elongated members each having a distal end coupled to a respective one of the first group of runners between the cuff and the stent and a proximal end overlying the abluminal surface adjacent the proximal end of the stent and coupled to the proximal end of the panel at circumferentially spaced apart locations, the plurality of elongated members having a tensioned state when the panel is arranged in the first orientation and a relaxed state when the panel is arranged in the second orientation, the panel folding back upon itself toward the distal end of the stent to move from the first orientation to the second orientation when the plurality of elongated members move from the tensioned state to the relaxed state to create a bunched-up ring of sealing material.
