[Left ventricular assist devices in cardiogenic shock]. / Assistances circulatoires dans les chocs cardiogéniques.

Cardiogenic shock is the leading cause of in-hospital death for myocardial infarction. Despite therapeutic improvements, such as medical treatment with inotropes, myocardial revascularization, circulatory assistance can be an option. Intra-aortic balloon pumping is highly recommended in the presence of haemodynamic impairment. If the patient continues to deteriorate and cardiac function cannot maintain adequate circulation to prevent end-organ failure, several mechanical circulatory assist devices can be considered: extracorporeal membrane oxygenator (ECMO), Impella(®)… These devices should be used at tertiary centres either as bridge to recovery or as bridge to transplantation or as bridge to long-term left ventricle assist device.
