For the first time in the U.S., doctors have brought a heart back to life and successfully transplanted it into another person. They used a special device to revive the heart of a 26-year-old donor who died of cardiac arrest on Sunday. The doctors then transported the beating heart from Ohio to Duke University Hospital in North Carolina where surgeons transplanted it into a military veteran. Dr. Tara Narula joins "CBS This Morning" to discuss the Organ Care System or Heart-in-a-Box device.
