Percutaneous Aortic Valve Replacement
Percutaneous aortic valve replacement implants the valve using a catheter, without open heart surgery. It is used in more than 50 countries in patients who are at extreme or high risk to undergo open heart surgery. The SAPIEN valve is made by Edwards Lifesciences. The Medtronic CoreValve system is another device used for this procedure, undergoing clinical trials in the United States.
In high-risk patients with severe aortic stenosis, transcatheter and surgical procedures for aortic-valve replacement had similar rates of survival at 1 year, although there were important differences in risks associated with the procedure. The transcatheter procedure was associated with a higher risk of stroke than the surgical replacement (5.5% vs. 2.4% after 30 days; 8.3% vs. 4.3% after 1 year).

Famous quotes containing the word replacement:
“Not even the visionary or mystical experience ever lasts very long. It is for art to capture that experience, to offer it to, in the case of literature, its readers; to be, for a secular, materialist culture, some sort of replacement for what the love of god offers in the world of faith.”
—Salman Rushdie (b. 1947)
