Abstract
A collapsible prosthetic heart valve includes a stent and a valve assembly. The stent has an annulus section with a relatively small cross-section, and an aortic section with a relatively large cross-section. The valve assembly, including a cuff and a plurality of leaflets, is secured to the stent in the annulus section such that the valve assembly can be entirely deployed in the native valve annulus and function as intended while at least a portion of the aortic section is held by the delivery device in a manner that allows for resheathing. The configuration of the prosthetic valve is such that the valve leaflets can fully coapt and the valve can function properly even when the stent and/or valve assembly become distorted upon deployment or use.
