In August 2006, an artificial heart was implanted into a 15-year-old girl at the Stollery Children's Hospital in Edmonton, Alberta. It was intended to act as a temporary fixture until a donor heart could be found. Instead, the artificial heart (called a Berlin Heart) allowed for natural processes to occur and her heart healed on its own. After 146 days, the Berlin Heart was removed, and the girl's heart functioned properly on its own. On 16 December 2011 the Berlin Heart gained U.S. FDA approval. The device has since been successfully implanted in several children including a 4-year-old Honduran girl at Children's Hospital Boston.
