With a rapid, progressive course of deterioration, it causes refractory cardiorespiratory failure even with optimal clinical intervention. We present the case of a 9-year-old girl with FM complicated by cardiogenic shock, malignant arrhythmia, and refractory cardiac arrest. She received effective cardiopulmonary resuscitation, therapeutic hypothermia, and other supportive treatments. However, the patient rapidly worsened into pulseless ventricular tachycardia and refractory cardiac arrest. Therefore, we performed extracorporeal membrane oxygenation (ECMO) to establish spontaneous circulation after the failure of standard resuscitation measures. The girl recovered with intact cardiac and neurocognitive functions after continued ECMO treatment for 221 hours. Therefore, ECMO is an effective rescue therapeutics for FM, especially when complicated with refractory cardiac arrest.
