Organ donation after circulatory death (DCD) now accounts for nearly half of all deceased organ donors in the US. This is a dramatic shift in transplant practice over the past 25 years. Analysis of national data confirms this trend. DCD involves harvesting organs after circulatory arrest, which used to be the main source of organs until the 1970s. This method increases the number of organs available for transplantation. In this way, the number of donated organs has significantly increased in the USA.
