Abstract
BACKGROUND: Both combined heart-kidney transplantation and ventricular assist devices (VADs) pose significant challenges, including sensitization, immunosuppressive treatment, and infrastructure demands. Despite these challenges, we hypothesized that the recipients of combined heart-kidney transplants with and without VADs would have equivalent survival. We aimed to compare the survival of heart-kidney transplant recipients with and without prior VAD placement.METHODS: We retrospectively analyzed all patients enrolled in the United Network for Organ Sharing database who underwent heart-kidney transplants. We created a matched cohort of patients undergoing heart-kidney transplantation with or without prior VAD using 1:1 nearest propensity-score matching with preoperative variables.RESULTS: In the propensity-matched cohort, 399 patients underwent heart-kidney transplantation with prior VAD, and 399 underwent heart-kidney transplantation without prior VAD. The estimated survival of heart--kidney recipients with prior VAD was 84.8% at one year, 81.2% at 3 years, and 75.3% at 5 years. The estimated survival of heart-kidney recipients without prior VAD was 86.8.7% at one year, 84.0% at 3 years, and 78.8% at 5 years. There was no statistically significant difference in the survival of heart-kidney transplant recipients with or without prior VAD at one year (P=.42; Figure 2), 3 years (P=.34), or 5 years (P=.30).CONCLUSION: Despite the increased challenge of heart-kidney transplantation in recipients with prior VAD, we demonstrated that these patients have similar survival to those who underwent heart-kidney transplantation without previous VAD placement.
