Peter Houghton (20 August 1938 – 25 November 2007) was the longest surviving artificial heart transplant patient in the UK.
After the operation, the left ventricular assist device worked continuously supporting his heart, breaking the previous world duration record on 11 August 2004 at 1,513 days.
A few individuals have lived longer than 1,512 days but with two artificial hearts, having the first surgically replaced due to failure or wear.
Houghton was the first person in the world to be given an artificial heart for permanent use rather than as a bridge to transplantation.
An educated psychotherapist, Houghton has written a book, "The World Within Me," in which he contemplates how receiving the transplant challenges his devout Catholicism.
