Introduction: Re‐transplant is an option for those who develop end‐stage lung disease due to rejection; however, little data exist following re‐transplantation in cystic fibrosis (CF). Methods: Data from the Canadian CF Registry and US CF Foundation Patient Registry supplemented with data from United Network for Organ Sharing were used. Individuals who underwent a 2nd lung transplant between 2005 and 2019 were included. The Kaplan‐Meier method was used to estimate the probability of survival post‐second transplant at 1, 3, and 5‐years. Results: Of those people who were waitlisted for a second transplant (N = 818), a total of 254 (31%) died waiting, 395 (48%) were transplanted and 169 (21%) people were alive on the waitlist. Median survival time after 2nd lung transplant was 3.3 years (95% CI: 2.8‐4.1). The 1‐, 3‐ and 5‐year survival rates were 77.4% (95% CI: 73.1‐82%), 52% (95% CI: 46.7‐58%) and 39.4% (95% CI: 34.1‐45.6%). Conclusions: Survival following second lung transplant in CF patients is lower than estimates following the first transplant. Over half of subjects who are potentially eligible for a second transplant die without receiving a second organ. This warrants further investigation. [ABSTRACT FROM AUTHOR]
