Cardiogenic shock (CS) portends an extremely high mortality of nearly 50% during index hospitalization. Prompt diagnoses of CS, its underlying etiology, and efficient implementation of treatment modalities, including mechanical circulatory support (MCS), are critical especially in light of such high predicted mortality. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) provides the most comprehensive cardiopulmonary support in critically ill patients and hence has seen a steady increase in its utilization over the past decade. Hence, a good understanding of VA-ECMO, its role in treatment of CS, especially when compared with other temporary MCS devices, and its complications are vital for any critical care cardiologist. Our review of VA-ECMO aims to provide the same.
