Eligibility
Inclusion criteria
Inclusion criteria: On VA-ECMO support for any indication. According to our centre*s protocol, indications for VA-ECMO initiation are hemodynamic and/or respiratory failure, cardiogenic shock, (accidental) hypothermia, ECPR, bridge to cardiac assist device implant and bridge to heart (and/or lung) transplant. In short, all patients on VA-ECMO support are eligible for study participation, irrespective of their clinical indication for VA-ECMO initiation. We foresee study results will not be influenced by patient selection, since study inclusion criteria do not comprise any clinical conditions.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary study endpoints are the biventricular pressure volume loop characteristics reflecting cardiac mechanoenergetics, including stroke work and potential energy (together extrapolated into the pressure volume area) compared between 4.0-3.0-2.0-1.0-0.5 L/min VA-ECMO blood flow in individual patients. Regarding the substudy: The difference in LV preload in individual VA-ECMO patients, reflected by the LV PVL derived parameter End-Diastolic Volume (EDV in mL). this parameter will be measured at 100% VA-ECMO blood flow for each PEEP level (i.e. 20, 10 and 0 cmH20). | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary endpoints are differences in additional biventricular pressure-volume loop parameters between 4.0-3.0-2.0-1.0-0.5 L/min extracorporeal VA-ECMO blood flow, including stroke volume, (forward and power) cardiac output, preload recruitable stroke work, tau, intraventricular dyssynchrony (both systolic and diastolic), dP/dt (maximal and minimal), effective arterial elastance and end-systolic elastance (the ratio between both reflecting ventricular-arterial coupling), the ventricular stiffness constant β, end-diastolic volume, end-diastolic pressure (including the end-diastolic pressure volume relation, EDPVR, trendline) as well as end-systolic volume, end-systolic pressure (including the end-systolic pressure volume relation, ESPVR, trendline), Starling Contractile index, stroke work to pressure volume area ratio as well as the ventricular volume on 0, 15, 30 and 100 mmHg ventricular pressure. | — |
