I just asked my surgeon at the Cleveland clinic about this today. My surgery is tomorrow. He said that they were doing this, but they have stopped b/c of some problem or complication - sorry I can't remember specifically the problem - my mind has been racing and not really absorbing all the info thrown at me. But bottom line - he said this "would not be a good choice for me." I am having a hopeful aortic valve repair, but if unable to repair, a replacement.
If you find out anymore on this I'd still be interested to hear.
Best to you.
