Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

REMAP ECMO is a registry based platform in which multiple response adaptive randomized clinical trials (trial domains) will be embedded. These trial domains will, in a perpetual way, study the effects of a range of patient management strategies which aim to improve VA ECMO weaning success. A first trial domain will address the effects of left ventricular (LV) unloading through intra-aortic balloon pumping on weaning succes in VA ECMO supported patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

ExtraCorporeal Membrane Oxygenation (ECMO) is increasingly used but remains associated with high weaning failure- and mortality- rates. This seems in part attributable to a knowledge gap on how to properly manage ECMO and its related therapies as current knowledge and treatment protocols are based on observational studies and expert opinions. The "Randomized Embedded Multifactorial Adaptive Platform in ECMO" (REMAP ECMO) study was developed to study, in an efficient and randomized way, different ECMO related patient management issues and will consist of two parts:

1. A patient registry that will serve for quality monitoring and observational studies of ECMO patients being treated in participating centers.
2. Embedded within the registry, multiple response adaptive randomized clinical trials (trial domains) which aim to evaluate the effectiveness of a range of therapeutic interventions on ECMO weaning success. These interventions all have in common that they are all already used in ECMO care but their use depends on center and/or doctors preferences as no high quality (randomized) evidence guiding their indication, timing and management exists.

* LV unloading trial A first trial domain to be initiated within the REMAP ECMO platform will address the effects of left ventricular (LV) unloading, through application of an intra-aortic balloon pump (IABP), on weaning success in the setting of venoarterial (VA) ECMO. The rationale of this trial domain is based on the increase in LV loading conditions, as induced by VA ECMO, which could lead to pulmonary edema, intracardiac thrombosis and even death. These serious sequelae could possibly be prevented by adding IABP as adjunct to VA ECMO therapy.
* Physiological substudy on IABP as adjunct to V-A ECMO

A nested physiological observational substudy within the ongoing REMAP ECMO RCT, using the trial arms where patients are randomized between receiving V-A ECMO with or without IABP in the Erasmus Medical Center Rotterdam. The substudy aims to evaluate the physiological effects of IABP in conjunction with V-A ECMO on respiratory and hemodynamic parameters. The substudy consists of two parts:

1. Microcirculation and Macrocirculation: This part investigates the impact of IABP on both microcirculation and macrocirculation in the setting of V-A ECMO.
2. PEEP as an Unloading Modality: This part examines the effect of Positive End-Expiratory Pressure (PEEP) as an unloading modality during a decremental PEEP trial in patients receiving V-A ECMO, either with or without IABP.

Endpoints in both substudies that can be assessed blindly will be evaluated by an assessor who is blinded to the assigned treatment arm and the objectives of the substudy

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

IABP unloading arm

This group of patients will receive an intra-aortic balloon pump (IABP) as an adjunct to VA ECMO support. When allocated to the IABP unloading arm, patients must receive an IABP within 8 hours after VA ECMO initiation.

Group Type EXPERIMENTAL

Intra-aortic balloon pump

Intervention Type DEVICE

An IABP is placed percutaneously into the thoracic aorta and supports the heart through synchronized inflation and deflation of a balloon.

ECMO alone arm

This group of patients will receive VA ECMO support without left ventricular unloading device after randomization.

Group Type NO_INTERVENTION

No interventions assigned to this group
