A 40-year-old father has become the first person in the UK to receive a total artificial heart that will enable him to go home.
Matthew Green had been critically ill, suffering from end-stage failure of both chambers of his heart.
But today he was preparing to return home after undergoing the ground-breaking surgery at Papworth Hospital, near Cambridge.
Doctors at the hospital have previously implanted a total artificial heart but this is the first time a patient has been well enough to leave hospital and go home.
