Effects of left ventricular unloading during VA ECMO support

Official title: Randomized Embedded Multifactorial Adaptive Platform in ExtraCorporeal Membrane Oxygenation (REMAP ECMO) - Left Ventricular Unloading Study

Run by Erasmus Medical Center · NCT05913622 · Data updated 2026-11-12

This study is testing whether using an intra-aortic balloon pump along with VA ECMO support can help patients with heart failure recover better than just using VA ECMO alone.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older experiencing cardiogenic shock who have received VA ECMO support for severe circulatory and/or respiratory insufficiency.

Probably not a fit

Patients who are pregnant or those whose ECMO usage is limited to surgical procedures may not benefit from this study.

What this trial studies

This study investigates the impact of left ventricular unloading using an intra-aortic balloon pump (IABP) on the success of weaning patients from venoarterial extracorporeal membrane oxygenation (VA ECMO) support in cases of cardiogenic shock. It is part of the REMAP ECMO platform, which aims to evaluate various management strategies for ECMO patients through a registry and embedded adaptive randomized trials. The study seeks to fill the knowledge gap regarding optimal ECMO management by providing high-quality evidence on the effectiveness of established interventions. The trial will compare outcomes between patients receiving VA ECMO with IABP support and those receiving VA ECMO alone.

Why it matters

Potential benefit: If successful, this study could improve weaning success rates from VA ECMO, potentially reducing mortality in patients with cardiogenic shock.

How similar studies have gone: Other studies have explored various management strategies in ECMO, but this specific approach of LV unloading in the context of VA ECMO is novel and aims to provide new insights.

Who can join: the full rules

Show full inclusion / exclusion criteria
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
