ECMO support can rescue 40% of otherwise fatal cardiogenic shock patients but its initiation under cardiac massage or after renal or hepatic failure carried higher risks of intensive care unit death, while fulminant myocarditis had a better prognosis. Despite satisfactory mental health and vitality, long-term survivors' persistent physical and social problems might benefit from tailored medical or psychosocial interventions.

Patients who tolerated a full ECMO weaning trial and had aortic VTI ≥10 cm, LVEF >20-25%, and TDSa ≥6 cm/s at minimal ECMO flow were all successfully weaned. However, further studies are needed to validate these simple and easy-to-acquire Doppler echocardiography parameters as predictors of subsequent ECMO weaning success in patients recovering from severe cardiogenic shock.

Venoarterial extracorporeal membrane oxygenation rescued more than 70% of the patients who developed refractory cardiovascular dysfunction during severe bacterial septic shock. Survivors reported good long-term quality of life. Venoarterial extracorporeal membrane oxygenation might represent a valuable therapeutic option for adults in severe septic shock with refractory cardiac and hemodynamic failure.

Mechanical circulatory assistance rescued 68% of patients with refractory circulatory failure due to fulminant myocarditis. Greater disease severity and higher troponin Ic levels at extracorporeal membrane oxygenation initiation predicted poorer prognosis. Because up to one-third of the patients reported anxiety, depression, and/or posttraumatic stress disorder symptoms, strategies aimed at attenuating their emotional and psychologic distress might significantly improve their long-lasting well-being.
