TRANSCATHETER MITRAL VALVE STENT FRAMES

摘要

A prosthetic heart valve may include a stent having an inflow end, an outflow end, a collapsed condition, and an expanded condition. The prosthetic valve may also include a collapsible and expandable valve assembly disposed within the stent and having a plurality of leaflets. The prosthetic valve and/or stent may include features to anchor the prosthetic valve to a native valve annulus and to seal the prosthetic valve with respect to the native valve annulus, such as planar and/or nonplanar annular sealing members coupled to ends of the stent. The stent may include one or more circumferential rows of anchor members or hooks extending radially outwardly from the stent. These hooks may be configured to extend in a particular direction when the stent is in the collapsed condition to facilitate resheathing of the stent if, upon deployment, a user determines the prosthetic heart valve is not positioned optimally.
