Heart of a Champion - Justin Ryder

Justin Ryder has battled heart problems nearly all his adult life. But after multiple surgeries, the 35-year-old Las Vegas, Nev., resident finally has a ticker that works - SynCardia's temporary Total Artificial Heart. Running out of options with his patched-up natural heart, Ryder had an artificial one implanted in early December at the University of Arizona Medical Center. It keeps him going, literally, while he awaits a donor heart.
