Journal Review in Thoracic Surgery: VV ECMO in Pre-Lung Transplant Patients - A Bridge to Somewhere

This episode of Behind the Knife explores the evolving role of venovenous extracorporeal membrane oxygenation (VV ECMO) as a bridge to lung transplantation, shifting from a last-resort salvage therapy to a strategic tool for preserving physiological reserve. Host Kyla Rakozi and guest Dr. Alfred Kassilian, a thoracic surgeon at Johns Hopkins, review key studies that demonstrate how awake, non-intubated ECMO allows patients to remain mobile and engaged in physical therapy, leading to improved post-transplant outcomes. They highlight the importance of ambulation, the benefits of avoiding pre-transplant intubation, and the risks of prolonged ECMO duration, while noting that one-year survival is not negatively impacted by longer bridge times if transplantation is achieved. The discussion underscores a paradigm shift in transplant medicine, driven by research and institutional expertise, with future advancements in ex vivo lung perfusion and donor organ preservation poised to make lung transplantation more elective and accessible. Key takeaways include: 1) VV ECMO should be viewed as a bridge to optimize patients, not just rescue them; 2) Non-intubated, awake ECMO is associated with better short- and long-term outcomes; 3) Early transplantation during ECMO support may improve survival on the waitlist; 4) Ambulation during ECMO is a critical predictor of success; and 5) Prolonged ECMO use increases complications but does not harm long-term survival if transplant is achieved. The episode concludes with excitement about emerging technologies that could transform lung transplantation into a more planned, elective procedure.
