Here how doctors in the UK did it.
Doctors saved a man's life by transplanting a "dead" heart they were able to bring back to life.
Dubbed "heart in a box", is a new pioneering piece of technology that can preserve the organ and keep it beating for almost eight hours, the Daily Mail reported.
The heart transfer to 58-year-old Anthony Anderson was carried out by surgeons at Wythenshawe Hospital in Manchester (UK).
Anderson was diagnosed with cardiomyopathy which left him in urgent need of a transplant.
On hearing news that a heart for him was available, Anderson told Daily Mail: "When I got the call I felt very emotional – really happy, but of course sad that someone had to die to help me and I will be forever grateful to my donor."
Wythenshawe Hospital is among only four hospitals in the world to carry out this unique procedure.
Manchester Evening News reported that only a few people have undergone this treatment.
In every 100 patients 15 people die while waiting for a heart transplant.
However, doctors are hopeful this technology could save many lives.
