Controversies in extracorporeal membrane oxygenation: Immediate versus watchful waiting for venoarterial extracorporeal membrane oxygenation ventingCentral Message

In patients in cardiogenic shock (CS), mechanical circulatory support (MCS) may improve systemic perfusion without increasing myocardial work. Restoration of oxygen delivery with reduced myocardial oxygen demand favors myocardial recovery. The hemodynamic effects of MCS have been extensively studied and elegantly reviewed previously. Pressure-volume loop simulations suggest that although venoarterial extracorporeal membrane oxygenation (VA-ECMO) may improve systemic perfusion, accompanying consequences on left ventricular (LV) dynamics may be detrimental.
