This is the emotional moment a teenager burst into tears after waking up from heart transplant surgery and realising he is still alive.
Trevor Sullivan, 15, from Detroit, Michigan, is seen on camera hooked up to breathing tubes and heart monitors as he lies still on his hospital bed.
Through deep breaths, the boy realises he is awake, and that his has survived the major procedure.
“I’m so happy. I’ve been waiting so long. I can breathe again and talk.”
