- Abstract
Introduction: Donation after circulatory death (DCD) donors are becoming an important source of organs for heart-transplantation (HT), but there are limited data regarding their use in multiorgan-HT., Methods: Between January 2020 and June 2023, we identified 87 adult multiorgan-HTs performed using DCD-donors [77 heart-kidney, 6 heart-lung, 4 heart-liver] and 1494 multiorgan-HTs using donation after brain death (DBD) donors (1141 heart-kidney, 165 heart-lung, 188 heart-liver) in UNOS. For heart-kidney transplantations (the most common multiorgan-HT combination from DCD-donors), we also compared donor/recipient characteristics, and early outcomes, including 6-month mortality using Kaplan-Meier (KM) and Cox hazards-ratio (Cox-HR)., Results: Use of DCD-donors for multiorgan-HTs in the United States increased from 1% in January to June 2020 to 12% in January-June 2023 (p < 0.001); but there was a wide variation across UNOS regions and center volumes. Compared to recipients of DBD heart-kidney transplantations, recipients of DCD heart-kidney transplantations were less likely to be of UNOS Status 1/2 at transplant (35.06% vs. 69.59%) and had lower inotrope use (22.08% vs. 43.30%), lower IABP use (2.60% vs. 26.29%), but higher durable CF-LVAD use (19.48% vs. 12.97%), all p < 0.01. Compared to DBD-donors, DCD-donors used for heart-kidney transplantations were younger [28(22-34) vs. 32(25-39) years, p = 0.004]. Recipients of heart-kidney transplantations from DCD-donors and DBD-donors had similar 6-month survival using both KM analysis, and unadjusted and adjusted Cox-HR models, including in propensity matched cohorts. Rates of PGF and in-hospital outcomes were also similar., Conclusions: Use of DCD-donors for multiorgan-HTs has increased rapidly in the United States and early outcomes of DCD heart-kidney transplantations are promising., (© 2024 John Wiley & Sons A/S.
