Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main question to be asked in this study is what is the potential for human hearts that have been deemed unacceptable for transplant, to be explanted and re-animated in a controlled, external environment to be assessed? Furthermore would the reanimated hearts be able to undergo improvement in their function in this external environment.

Ultimately this may lead to an increase the number of hearts available for transplantation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Year on year with improvement in road safety and improvement in neurosurgery the number of ideal young brain dead donors have been declining whilst the number of more marginal donors have been increasing. The consequence of this is the number of heart transplants being performed have steadily declined.

At present there are 600 hearts from brain dead donors offered for transplant every year in the United Kingdom (UK). Of these 200 have anatomical reasons why they cannot be used for transplant such as ischaemic heart disease. 100 are transplanted and the remaining 300 hearts are judged to have inferior function which probably occurs as a direct result of brain death (Dark).

Ex vivo 'rig' testing has been developed for lungs that were judged unsuitable for transplantation. As a result several donor lungs have been 'improved' by warm perfusion on the rig to the extent that they became suitable for transplantation and so national lung transplant rates are increasing (Dark). The aim would be to develop a similar approach for the heart.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Organ Donors (declared Brainstem-Dead)

This group of subjects is defined as those who have previously expressed their future wish to organ donation and who have suffered events leading to declaration of brainstem-death. Furthermore these subjects will have had their hearts declined for heart transplantation on the basis of poor function.

No interventions assigned to this group
