Totally Artificial Heart (TAH)
The US government funded a project to create a totally artificial heart in 1964. Bioengineers thought that a fully functional totally artificial heart would have been created within the next 10 years. In 1964 the Liotta TAH was used to bridge the period between the need for a transplant and the provision of a heart from a donor. The totally artificial heart kept the patient alive for 64 hours, at which point the patient received a transplant and died 32 hours later. In 1981 the Akatsu TAH was also used as a bridge heart for a period of 9 days, although the patient dies 9 days after the final transplant this was still an improvement. The Jarvic-7 came along in 1982 and was fitted to the first patient, Barney Clark, in an attempt to replace his heart and he lived for 112 days after the transplant. The second patient to be fitted with the Jarvic-7 TAH was William Schroeder, although he lived for 620 days he still experienced problems with the Jarvic-7 1985 saw the Phoenix TAH used as a bridge heart to a transplant, only to have the patient die 12 hours after the final transplant. 2000; Abiomed will implant a brain-dead person with a new electro-hydaulic heart, as a finale to 10 years of research 2001

While originally used as a permanent replacement heart, the Total Artificial Heart is approved for use as a bridge to transplant in cardiac transplant-eligible candidates at risk of imminent death from biventricular failure.
