Lung Transplantation for End-Stage Respiratory Failure After Severe COVID-19: A Report of 2 Cases.

We report 2 cases of bilateral lung transplantation for nonresolving coronavirus disease 2019 associated respiratory failure. In the first patient, the severe acute respiratory syndrome coronavirus 2 infection caused acute respiratory distress syndrome requiring prolonged extracorporeal membrane oxygenation support; in the second patient, coronavirus disease 2019 resulted in irreversible pulmonary fibrosis requiring only ventilatory support. The 2 cases represent the 2 ends of the spectrum showing significant differences in preoperative and postoperative courses.
