PurposeTakotsubo cardiomyopathy is characterized by the sudden onset of reversible left ventricular dysfunction. Associated refractory cardiogenic shock is a rare occurrence and may require extracorporeal membrane oxygenation (ECMO). We report a case of a patient who, following the inadvertent injection of 1 mg of epinephrine, presented with reverse Takotsubo cardiomyopathy and refractory cardiogenic shock that required the implementation of a percutaneous ECMO.Clinical FeaturesA 49-yr-old female patient presented with reverse Takotsubo cardiomyopathy in the operating room after an inadvertent injection of epinephrine. The development of refractory cardiogenic shock required emergent use of a mobile percutaneous ECMO system. It was possible to wean this support after four days, and the patient was later discharged without cardiac or neurological sequelae. The investigations performed confirmed the iatrogenic nature of this reverse Takotsubo cardiomyopathy.ConclusionTakotsubo cardiomyopathy following an injection of epinephrine remains a rare but increasingly described occurrence. The severity of the symptoms appears to be patient dependent, but refractory cardiogenic shock may occur and require significant circulatory support. If this situation occurs in a hospital where this necessary equipment is lacking, a mobile ECMO unit appears to be a viable solution to optimize the patient's chances of survival.
