Abstract
A heart prosthesis system may include a prosthetic heart valve and a length of suture. The prosthetic heart valve may include a collapsible and expandable stent and a valve assembly mounted within the stent. The stent may have an aortic end, an annulus end, and a plurality of openings arranged circumferentially around the aortic end, the aortic end having a first diameter in an expanded condition. The length of suture may be threaded through the openings such that tension applied to the length of suture in a direction away from the stent may collapse the aortic end of the stent from the first diameter to a second diameter less than the first diameter.
