Why?

  From what I have read, artificial heart valves, being artificial, are simply not really covered by the immune system. In other words, you get white blood cells to the point of infection because you have blood supply and mechanical parts don't have blood vessels running through them. It's foreign matter, not really part of a living body. Very likely, they probably also attract infections that like eating plastics and such. These are inherently hard for the human body to combat if they get traction, from what I gather. They aren't a normal infection in humans and tend to be deadly when they do take root.
