Extracorporeal Membrane Oxygenation and Microaxial Left Ventricular Assist Device in Cardiogenic Shock: Choosing the Right Mechanical Circulatory Support to Improve Outcomes.

Impact of shock phenotype on 30-day survival with Impella (CP/5.0) or venoarterial extracorporeal membrane oxygenation (VA-ECMO). A support strategy that distinguishes cardiac phenotypes can streamline clinical decision-making in patients with SCAI stages C-D-E. The approach studied favors Impella for isolated left ventricular dysfunction and VA-ECMO for biventricular dysfunction or multiple organ failure. Patients with biventricular dysfunction or multiple organ failure supported with Impella had worse 30-day survival. Patients with isolated left ventricular dysfunction who were supported by Impella or VA-ECMO had good 30-day survival.
