**Abstract**

If cardiac function is restored, we should consider discontinuing extracorporeal membrane oxygenation (ECMO) support. Except for patients who go to transplantation or ventricular assist device, the patient's condition should be evaluated steadily every day to determine and implement the weaning. Treatment interruption can be determined based on hemodynamic parameters, laboratory findings, and echocardiographic findings. Weaning is determined, and catheter removal is surgically removed or pressed by hand, and closure device is also used. Depending on the patient's condition and the decision of each center, the appropriate method can be selected. Since various complications may occur after removal, intensive observation should be carried out for a certain period of time.
