Balloon pump may boost ECMO success in shock patients
NCT ID NCT05913622
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether adding an intra-aortic balloon pump (IABP) to standard ECMO support helps more people with severe cardiogenic shock recover enough to come off the heart-lung machine. About 430 adults will be randomly assigned to get ECMO alone or ECMO plus IABP. The main goal is to see who can be weaned from ECMO within 30 days without needing a heart transplant or permanent heart pump.
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 an IABP helps more patients successfully come off ECMO without needing a heart transplant or long-term heart pump.
- What could go wrong
- This is an early-stage platform trial, so results may not be definitive. The IABP itself carries risks like bleeding or vessel damage, and the benefit over ECMO alone is unproven.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion criteria for the registry backbone: * Having received ECMO support for severe circulatory and/or respiratory insufficiency Inclusion Criteria for the LV unloading trial domain (VA ECMO + IABP vs VA ECMO alone): * Cardiogenic shock * Having received VA ECMO support for severe circulatory (and respiratory insufficiency). * Age ≥ 18 years * Initiation of LV unloading (IABP or Impella) possible ≤ 8 hours after ECMO initiation Exclusion criteria for the registry backbone * Objection to participation in the registry by the patient and/or proxy * VA ECMO usage confined to the period during surgery or another intervention (the VA ECMO was removed at the end of the intervention in the operation room). Exclusion criteria for the LV unloading trial domain (VA ECMO + IABP vs VA ECMO alone) * No (deferred) informed consent provided by the patient and/or proxy. * Pregnancy * ECMO usage confined to the period during surgery or another intervention (the ECMO was removed at the end of the intervention). * Isolated right ventricular failure (e.g. due to pulmonary embolism). * Left ventricular assist device (LVAD), Impella or IABP in situ. * Ventricular septal defect or papillary muscle rupture as the cause of shock. * Thoracic or abdominal aortic dissection. * Moderate or severe aortic regurgitation * Mechanical prosthesis in mitral valve position
