*****FROM ABC NEWS MEDICAL UNIT*****
I believe that this is the dotcom article to the procedure that you are referring to: http://abcnews.go.com/GMA/OnCall/story?id=6589797&page=1 . Columbia Presbyterian Medical Center has attatched their email address to the end of this article - feel free to email them to learn more about the procedure. In addition there is a link to the clinical trial in the article and links for more information about the heart valve. I hope this is what you were looking for.
