Leading Heart Valve Manufacturer, Edwards Lifesciences, Reaches 52-Week High http://www.heart-valve-surgery.com/heart-surgery-blog/2009/06/22/leading-heart-valve-manufacturer/#comment-11024 Mon, 22 Jun 2009 18:48:45 +0000 http://www.heart-valve-surgery.com/heart-surgery-blog/2009/06/22/leading-heart-valve-manufacturer/#comment-11024 Hello Adam. Are you familiar with the On-X valve made by Medical Carbon Research Group in Austin TX? It looks to me like it may require less anti-coagulation because of it's patented silicone-free pyrolytic carbon surface, lower pressure gradients, and improved pivot washing. I am new to this game since I just found out a few weeks ago that I will require double-valve surgery. But after reading about this valve I am leaning towards it, Unless I hear something bad about it. I am 68 yr old and the thought of maintaining a high INR number in my old age worries me a lot. They have implanted a lot of these valves in South Africa where they have a large number of patients who don't take their Coumadin, and the incidence of thrombosis is as low with these people as would be expected with St. Jude valves with patients who properly maintain their INR levels. They are conducting clinical trials now with lower INR levels. Preliminary results are good. If it is approved by the FDA with lower INR levels, this valve might become the most popular one.
