Mechanical ventilation (MV) and extracorporeal membrane oxygenation (ECMO) are increasingly used to bridge patients to lung transplantation. We investigated the impact of using MV, with or without ECMO, before lung transplantation on survival after transplantation by performing a retrospective analysis of 826 patients who underwent transplantation at our high-volume center. Recipient characteristics and posttransplant outcomes were analyzed. Most lung transplant recipients (729 patients) did not require bridging; 194 of these patients were propensity matched with patients who were bridged using MV alone (48 patients) or MV and ECMO (49 patients). There was no difference in overall survival between the MV and MV+ECMO groups (p = 0.07). The MV+ECMO group had significantly higher survival conditioned on surviving to 1 year (median 1,811 days ([MV] vs. not reached ([MV+ECMO], p = 0.01). Recipients in the MV+ECMO group, however, were more likely to require ECMO after lung transplantation (16.7% MV vs. 57.1% MV+ECMO, p < 0.001). There were no differences in duration of postoperative MV, hospital stay, graft survival, or the incidence of acute rejection, renal failure, bleeding requiring reoperation, or airway complications. In this contemporary series, the combination of MV and ECMO was a viable bridging strategy to lung transplantation that led to acceptable patient outcomes.
