摘要:
A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable coupling stent, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the coupling stent attached thereto. The coupling stent may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes a hollow two-piece handle through which a balloon catheter passes. A valve holder is stored with the heart valve and the handle easily attaches thereto to improve valve preparation steps.
