摘要：
A prosthetic heart valve includes a stent extending in a longitudinal direction and having a plurality of commissure features. A valve assembly is secured to the stent, the valve assembly including a cuff and a plurality of leaflets. Each of the leaflets has a pair of attachment regions and a free edge extending between the attachment regions. A deflection feature disposed in each attachment region is configured and arranged to prevent the free edges of the leaflets from contacting at least one of the stent or the cuff.
