Abstract
A prosthetic valve may be used to repair a diseased or otherwise damaged heart valve such as the mitral valve. The prosthetic valve may include atraumatic anchor tabs which may be radiopaque or echogenic. A cinching mechanism may also be coupled to the prosthetic valve to control radial expansion of the prosthetic valve. The cinching mechanism may include a wire lasso or a belt. The prosthetic valve may include an expandable frame which has a reduced number of strut connection nodes to allow a lower profile collapsed configuration and tighter crimping. The commissure posts of the prosthetic valve may extend beyond an edge of the ventricular skirt portion of the device.
