Brief Summary:
Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is increasingly being used worldwide to treat severe cardiogenic shock. The survival rate of these patients has increased in the last decade, reaching 45-50% for patients with acute myocardial infarction (AMI), the most frequent indication of the technique, 50-60% for patients with end-stage dilated cardiomyopathy bridged to heart transplantation or long-term left ventricle assist device (LVAD) surgery, 60-70% for fulminant myocarditis, while it remains lower for post-cardiotomy cardiogenic shock (25-35%) and after cardiac arrest (20-40%). However, peripherally inserted VA-ECMO increases left ventricular (LV) afterload, that may lead to poorer clinical outcomes by fostering left ventricular distension, blood stagnation, aortic valve closure, all of which increasing pulmonary congestion and the need for mechanical ventilation and compromising myocardial recovery whenever it is possible, or delaying a bridge to a heart transplantation or long-term left ventricle assist device (LVAD) surgery for patients with end-stage cardiac dysfunction. Several methods have been proposed to reduce afterload after VA-ECMO, including the use of an intra-aortic balloon pump (IABP), balloon atrial septostomy, transseptal left atrial cannula insertion, and use of the left-sided Impella device (Abiomed, Danvers, MA, USA). The clinical benefits of left ventricular unloading have been suggested by many retrospective case-control studies, including a study by our group that showed that associating an IABP with peripheral VA-ECMO was independently associated with a lower frequency of hydrostatic pulmonary edema under ECMO and more days off mechanical ventilation. More recently, unloading the left ventricle with an IABP was associated with the best survival rate and security profile as compared to no unloading or unloading with a microaxial pump in 12,734 VA-ECMO patients included in the Extracorporeal Life Support Organization registry. It should also be mentioned that another large registry study showed that the greatest benefit of LV unloading under ECMO was observed with early versus delayed insertion of the unloading device. Lastly, the EARLY-UNLOAD randomized trial in which a transseptal left atrial cannula was used for LV unloading yielded negative results. However, it is important to note that 50% of control patients were rapidly transitioned to LV unloading, thereby compromising the opportunity to demonstrate a mortality benefit. It was also underpowered for the primary outcome of D30 mortality since it included only 116 patients As a result, the recourse to systematic early LV unloading remains highly heterogeneous in clinical practice.

Version no. 4.0 of 31/05/2019 associated to ECMO in \>70% of the cases in our series of AMI CS patients, only 5.8% of the patients included in the ECMO arm of the recent ECLS-Shock trial received an unloading device, which may have contributed to the neutral result of the study and the only randomized trial to date was underpowered and flawed by a very high rate of early cross-over. Indeed, there is large heterogeneity in current clinical practice, where decisions on whether to add an additional mechanical unloading device during VA-ECMO support vary widely.
Therefore, a new and adequately powered trial comparing systematic early left ventricular unloading to a conventional approach, with rescue left ventricular unloading only in case of clear and urgent indication, i.e. if overt hydrostatic cardiogenic pulmonary edema occurs, is urgently needed. The EULODIA trial is designed to test the hypothesis that early preventive left ventricle unloading with an IABP improves clinical outcomes as compared to conventional care with delayed curative unloading in patients under VA-ECMO for refractory cardiogenic shock.
