Implications of ECMO Bridging and Salvage Strategies on Mortality and PGD

Use of the ISHLT Revised definition identifies Grade 3 PGD as highly associated with mortality in the ECMO bridging and salvage era. ECMO use is increasing for both bridging and salvage strategies. ECMO bridging strategies do not seem to increase mortality in lung transplant patients unless Grade 3 PGD subsequently develops. ECMO salvage after transplant is associated with increased risk of mortality; however, it is likely used only in the severest cases, thus indication bias is likely present.
