The valves are broken out separately from the heart for purposes of donation, and the story also discusses a case of valve harvesting causing a problem.

I'm struggling to figure out where to draw the line until I can update my advance healthcare directive... all these tissues, as you say, can still be valuable. I mostly just hate the lack of transparency in these relationships, and that these organizations seem to be hiding this tissue use behind the actual process of organ donations...
