While data on ECMO as a bridge to isolated heart and lung transplantation have been described, our emerging experience with ECMO as a bridge to thoracic multiorgan transplantation is not yet well understood. This study aims to investigate temporal trends, utilization, and outcomes in ECMO as a bridge to thoracic multiorgan transplantation.</p><p><strong>Methods: </strong>The United Network for Organ Sharing database was used to identify adult patients undergoing thoracic multiorgan transplantation between 1987 and 2022. Exclusion criteria were recipient age <18 and bridging with other mechanical circulatory support including ventricular assist device (VAD) and intra-aortic balloon pump (IABP). Survival analysis was performed to compare outcomes between patients bridged to transplantation with ECMO and those who were not bridged.</p><p><strong>Results: </strong>Of 3,927 patients undergoing thoracic multiorgan transplantation, a total of 203 (5.2%) patients received ECMO as a bridge to transplantation. Among ECMO recipients, patients were most commonly bridged to heart-lung (45.8%), followed by heart-kidney (34.5%), and lung-kidney transplantation (11.8%). At a median follow-up of 35.5 months, unadjusted survival among patients bridged with ECMO was decreased versus multiorgan transplant recipients who were not bridged (p<0.001). With adjusted multivariable Cox regression, ECMO was independently associated with an elevated risk of mortality following multiorgan transplantation (HR 1.56 [1.21-2.02], p<0.01). Among patients surviving past 30 days following transplantation, conditional long-term survival was similar between those bridged with ECMO and those not bridged (p = 0.82).</p><p><strong>Conclusion: </strong>ECMO is increasingly utilized as a bridge to thoracic multiorgan transplantation, and is associated with increased 30 day mortality and decreased long-term survival.
