In recent years, the widespread use of partial mechanical cardiac support and even temporary complete replacement of cardiac function has been established in many intensive care units in the treatment of refractory cardiogenic shock. There is a difference between partial left-ventricular assist devices (LVAD) and the possibility of complete heart (and lung) replacement by extra corporeal life support (ECLS). Despite the use of mechanical support devices, the mortality of cardiogenic shock remains high. The consideration of using percutaneous LVAD and ECLS in cardiogenic shock should be considered in refractory cardiogenic shock patients in addition to support by catecholamines and after early revascularization in acute coronary syndromes. However, there are no large randomized studies evaluating mechanical support systems with respect to outcome in cardiogenic shock patients. German and international guidelines do not recommend the routine use of mechanical support as a first-line treatment in cardiogenic shock patients and emphasize that their application should be restricted to patients with therapy refractory shock. In other cases of noninfarct-related cardiogenic shock (e. g., poisoning, myocarditis), ECLS use should be considered as bridging therapy. ECLS may also be considered in cardiopulmonary resuscitation which is termed E‑CPR. According to registry data, E‑CPR may reduce mortality in selected patients. A possible application of ECLS is severe accidental hypothermia with cardiac arrest despite limited data. In these rare cases, early ECLS should be considered for rewarming and stabilization.
