Balloon pump may boost heart recovery in shock patients on ECMO
NCT ID NCT06336655
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether adding a balloon pump (IABP) to standard ECMO support helps the heart recover better in people with severe cardiogenic shock. About 104 adults will be randomly assigned to get ECMO alone or ECMO plus the balloon pump. Researchers will measure heart function and fluid buildup over five days to see if the extra device makes a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- intra-aortic balloon pump (IABP)
- What this could lead to
- If it works, this could show that adding a balloon pump to VA ECMO helps the heart recover better in people with severe cardiogenic shock.
- What could go wrong
- This is a Phase 2 trial with only 104 participants, so results are preliminary. The intervention may not improve outcomes and carries risks like bleeding or infection.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adult patients (age 18 years or older) * Diagnosis of acute cardiogenic shock (CS) * Patients failing medical therapy, defined as 1 or more of the following: 1. Society for Coronary Angiography and Interventions (SCAI) Stage C or greater 2. 2 or more inotropic medications and not improving 3. IABP in place and clinically worsening 4. Placed on VA ECMO for CS 5. In the opinion of the attending physician, patient has worsening CS and could require VA ECMO support in the near-term Exclusion Criteria: * Metastatic or stage 4 cancer * Atrial septostomy * Planned LV unloading on ECMO * Anticipated death \<72 hours * Existing durable left ventricular assist device (dLVAD) * Unwillingness to randomize * Patients who are pregnant
