Changing patterns in lung transplant for respiratory failure due to COVID-19 in the U.S.

Many patients with severe COVID-19 have been affected by acute respiratory distress syndrome, which has been associated with increased mortality, and up to 31% of these survivors had persistent interstitial lung abnormalities with impaired lung function and quality of life even after 6 to 24 months after initial disease. Lung transplantation quickly emerged as a viable therapy for select patients with respiratory failure due to COVID-19 by mid-2020. In this report, we identified 477 patients who underwent lung transplantation for COVID-19 in the U.S. between March 2020 and December 2022. The number of patients waitlisted and undergoing lung transplantation for COVID-19 increased steadily in the early part of the pandemic with a peak of 97 patients waitlisted between October and December 2021, before steadily decreasing since. Notably, the procedure is now increasingly being done for survivors of COVID-19 with pulmonary fibrosis, rather than for refractory ARDS patients. The 1-year post-transplant mortality was 13.7%.
