A prosthetic heart valve (100; 200), comprising: a collapsible and expandable stent (102; 202) having a proximal end, a distal end, an annulus section (110; 240) adjacent the proximal end, an aortic section adjacent the distal end, a transition section between the aortic section and the annulus section, and a plurality of cells (112; 212) connected to one another in annular rows around the stent from the proximal end to the distal end, each of the cells having a diamond shape formed by a plurality of struts, the annulus section having a first expanded cross-section, the aortic section having a second expanded cross-section larger than the first expanded cross-section, and the transition section having an expanded cross-section which transitions from the first expanded cross-section to the second expanded cross-section; a plurality of commissure points (116; 216) disposed at a juncture between the annulus section and the transition section; and a collapsible and expandable valve assembly (104; 204) disposed entirely within the annulus section between the proximal end of the stent and the plurality of commissure points, the valve assembly including a plurality of leaflets (108; 208) connected to the plurality of commissure points; the plurality of commissure points being spaced from the distal end of the stent by a selected distance such that the prosthetic valve can be partially deployed from a delivery device at a target site by withdrawing a portion of a sheath of the delivery device from around the prosthetic valve, and the valve assembly can function as intended while the distal end of the stent is held within the sheath of the delivery device in a manner that enables resheathing. a collapsible and expandable stent (102; 202) having a proximal end, a distal end, an annulus section (110; 240) adjacent the proximal end, an aortic section adjacent the distal end, a transition section between the aortic section and the annulus section, and a plurality of cells (112; 212) connected to one another in annular rows around the stent from the proximal end to the distal end, each of the cells having a diamond shape formed by a plurality of struts, the annulus section having a first expanded cross-section, the aortic section having a second expanded cross-section larger than the first expanded cross-section, and the transition section having an expanded cross-section which transitions from the first expanded cross-section to the second expanded cross-section; a plurality of commissure points (116; 216) disposed at a juncture between the annulus section and the transition section; and a collapsible and expandable valve assembly (104; 204) disposed entirely within the annulus section between the proximal end of the stent and the plurality of commissure points, the valve assembly including a plurality of leaflets (108; 208) connected to the plurality of commissure points; the plurality of commissure points being spaced from the distal end of the stent by a selected distance such that the prosthetic valve can be partially deployed from a delivery device at a target site by withdrawing a portion of a sheath of the delivery device from around the prosthetic valve, and the valve assembly can function as intended while the distal end of the stent is held within the sheath of the delivery device in a manner that enables resheathing.
