Objective The objective of this study was to examine early lung transplant outcomes following EVLP using a large national transplant registry. Summary of background data Lung transplantation in the United States continues to be constrained by a limited supply of donor organs. EVLP has the potential to significantly increase the available pool of donor lung allografts through the reconditioning of "marginal" organs. Methods The united network for organ sharing registry was queried for all adults (age ≥18) who underwent first-time lung transplantation between March 2018 (when united network for organ sharing began collecting confirmed donor EVLP status) and June 2019. Transplants were stratified by EVLP use. The primary outcome was short-term survival and secondary outcomes included acute rejection before discharge and need for extracorporeal membrane oxygenation support post-transplant. Results A total of 3334 recipients met inclusion criteria including 155 (5%) and 3179 (95%) who did and did not receive allografts that had undergone EVLP, respectively. On unadjusted descriptive analysis, EVLP and non-EVLP cohorts had similar 180-day survival (92% vs 92%, P = 0.9). EVLP use was associated with a similar rate of acute rejection (13% vs 9%, P = 0.08) but increased rate of early extracorporeal membrane oxygenation use (12% vs 7%, P = 0.04). After adjustment, EVLP use was not associated with significantly increased mortality (adjusted hazard ratio 0.99, 95% confidence interval 0.62-1.58) or acute rejection (adjusted odds ratio 0.89, 95% confidence interval 0.40-1.97) compared to non-EVLP use. Conclusions In the largest national series of EVLP lung transplant recipients, EVLP is associated with early recipient outcomes comparable to that of non-EVLP recipients with similar baseline characteristics. Longer term follow-up data is needed to further assess the impact of EVLP on post-lung transplant outcomes.
