Could early heart pump support save more lives in severe shock?
NCT ID NCT07027202
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding a balloon pump early to reduce pressure on the heart improves survival and recovery in 298 adults on ECMO for severe cardiogenic shock. Participants are randomly assigned to early preventive unloading or standard care with rescue unloading only if needed. The goal is to see if early intervention reduces deaths, complications, and time on life support.

Inclusion Criteria: 1. Patient on peripheral femoro-femoral VA ECMO for severe Cardiogenic shock for ≤24h 2. Initiation of LV unloading possible within 12 hours after randomization. 3. Consent obtained from a close relative or surrogate. Should such a person be absent, eligible patients will be randomized according to the specifications of emergency consent and the patient will be asked to give his/her consent for the continuation of the trial when his/her condition will allow. 4. Social security registration (AME excluded) Exclusion Criteria: 1. Age \<18 years 2. Pregnancy 3. Onset of VA-ECMO \>24 h 4. Overt pulmonary edema despite optimization of patient's management (titration of ECMO blood flow, inotropes, non-invasive mechanical ventilation with PEEP, diuretics or hemofiltration) requiring urgent LV unloading 5. ECMO for massive pulmonary embolism or primary RV failure 6. ECMO after heart transplant 7. ECMO after LVAD surgery 8. Resuscitation \>30 minutes before ECMO (cumulative low-flow time), except if the patient has fully recover consciousness at the time of randomization. 9. ECMO for refractory cardiac arrest (E-CPR) 10. Grade 3-4 aortic regurgitation 11. Mechanical complication of acute myocardial infarction (massive mitral regurgitation, pericardium drainage required, septal ventricular defect) 12. Patient moribund on the day of randomization 13. Cerebral deficit with fixed dilated pupils or Irreversible neurological pathology 14. Other severe concomitant disease with limited life expectancy \<1 year 15. Patient has a durable ventricular assist device, an IABP or another temporary mechanical circulatory support (other than ECMO) prior to enrollment. 16. Severe peripheral artery disease or previous aortic or ilio-femoral surgery precluding IABP or IMPELLA insertion.
