A 25-year-old man has just received a full heart transplant... but not before surviving for more than a year without a human heart inside his body. Instead, Stan Larkin wore an 'artificial heart' in a backpack 24/7 for 555 days, which pumped blood around his body and kept him alive. The success of the procedure suggests that the device could be used to sustain other patients with total heart failure while they're waiting for a donor. http://www.sciencealert.com/this-guy-lived-for-more-than-a-year-without-a-heart-in-his-body
