Outcomes of Multiorgan Heart Transplant Between Donation After Circulatory Death and Brain Death

There is insufficient data on the outcomes of donation after circulatory death (DCD) multiorgan transplant that includes heart. The primary objective of this study is to compare the overall survival outcomes of DCD and donation after brain death (DBD) multiorgan transplants. We identified all heart transplant patients from 2019 to June of 2023 using the United Network for Organ Sharing (UNOS) Database who also received an additional organ (kidney, liver, and lungs). A total of 1,844 DBD and 91 DCD multiorgan transplants occurred within the study period, the majority being combined heart-kidney transplantation. More patients were listed at a higher status in the DBD group ( p < 0.05) and were in the intensive care unit (ICU) before transplant ( p < 0.05). Despite the higher ischemia time in the DCD group ( p < 0.05), the overall unmatched survival did not differ between the two groups ( p < 0.05). Within the heart-kidney transplants, the overall survival between DBD and DCD heart-kidney transplants did not differ in either unmatched or matched groups (unmatched p = 0.5, matched p = 0.5). In conclusion, the data on the outcomes of DCD multiorgan transplants are limited. Still, our analysis of the currently available data suggests that the overall survival is comparable in the DCD multiorgan transplants.
