Surgical method for the treatment of aortic valve leakage and ascending aorta segment prostheses

摘要

The annular prosthesis consists of a reinforcing wire in a continuous ring shaped in the form of a healthy aortic valve ring and having a suture zone extending all the way round. The suture zone is joined to the reinforcing wire, and the two are covered with a sleeve of polymer fibers. The reinforcing wire is supple to facilitate insertion into the aorta, being made from a stainless alloy such as Elgiloy(Cobalt chrome-nickel alloy - RTM). The prosthetic ring can be joined to an aortic segment prosthesis by suturing or thermal welding.
