Fourteen-year-old D’Zhana Simmons sheds a tear of joy at a press conference in Miami, on Wednesday, Nov. 19, 2008. D’Zhana was kept alive for 118 days with a custom-made total artificial heart while awaiting a second transplant at Holtz Children Hospital on the University of Miami Memorial Medical Center. She is believed to be the first pediatric patient to survive without a heart while her circulation was supported with the unique device.
