1. A method of assembling a prosthetic heart valve, comprising:
- providing a collapsible and expandable stent having an annulus section and an aortic section, the annulus section having a first annulus diameter in a relaxed condition and a second annulus diameter less than the first annulus diameter in a collapsed condition;
applying a constraint to the stent to constrain the annulus section to a predetermined annulus diameter between the first annulus diameter and the second annulus diameter;
after applying the constraint, assembling at least one of a cuff or a plurality of leaflets to the constrained annulus section to form a prosthetic heart valve; and
removing the constraint from the stent prior to implantation of the prosthetic heart valve within a native valve annulus.

Abstract
A method of assembling a prosthetic heart valve includes providing a collapsible and expandable stent having an annulus section and an aortic section. The annulus section has a first diameter in a relaxed condition and a second diameter less than the first diameter in a collapsed condition. A constraint is applied to the stent to constrain the annulus section to a predetermined diameter between the first and second diameters. Applying a cuff and/or a plurality of leaflets to the stent in the constrained condition enables less material to be used. The resultant prosthetic valve is therefore able to be collapsed to a smaller diameter for introduction into a patient.
