The Japanese Society for Heart Transplantation has begun considering allowing heart transplants from donors who have died after circulatory death, a practice currently prohibited in Japan which only permits transplants from brain-dead donors. This potential shift is driven by the increasingly long wait times for patients needing heart transplants. The society aims to develop specific guidelines and recommendations for implementing this new method. Currently, a shortage of viable organs significantly limits the number of transplants performed annually. Allowing donations after circulatory death could substantially increase the availability of hearts for transplant. The society will focus on establishing protocols to ensure ethical and medical viability. This move represents a significant potential change in organ donation practices within the country.
