Insights

Simultaneous heart and kidney transplants (SHKTs) using donation after circulatory death (DCD) donors show outcomes comparable to those from donation after brain death (DBD) donors. This suggests DCD donors are a viable option for SHKTs, especially for patients with kidney issues.

Area of Science:

  • Transplantation immunology
  • Cardiovascular surgery
  • Nephrology

Background:

  • Limited evidence exists for heart and kidney transplants from donation after circulatory death (DCD) donors.
  • Outcomes of simultaneous heart and kidney transplants (SHKTs) using DCD donors compared to donation after brain death (DBD) donors are not well understood.

Purpose of the Study:

  • To compare graft outcomes and survival rates of SHKTs performed using DCD versus DBD donors.
  • To evaluate the viability of DCD donors for SHKTs.

Main Methods:

  • Analysis of the United Network for Organ Sharing database for adult SHKTs from May 2020 to September 2023.
  • Comparison of 91 DCD-SHKT cases with 273 propensity score-matched DBD-SHKT cases.
  • Multivariate Cox proportional hazards analysis to assess mortality risk.

Main Results:

  • Recipient and graft survival rates were comparable between DCD and DBD donor groups in the matched cohort.
  • Delayed graft function in kidneys was similar between DCD and DBD recipients.
  • Donor type (DCD) was not significantly associated with increased mortality risk.

Conclusions:

  • SHKTs using DCD donors demonstrate comparable survival and graft outcomes to those using DBD donors.
  • DCD donors represent a valuable option for SHKTs, potentially aiding donor selection for heart transplant candidates with renal impairment.
