Venoarterial extracorporeal membrane oxygenation (VA-ECMO) stabilizes hemodynamics in an electrical storm leading to cardiogenic shock. However, adverse effects of VA-ECMO are increased left ventricular (LV) afterload and LV end-diastolic pressure due to retrograde blood return. These adverse effects could be ameliorated by LV unloading with Impella insertion. This case illustrates the possible efficacy of adjunctive Impella insertion for a refractory electrical storm that is resistant to defibrillation under mechanical support with VA-ECMO for cardiogenic shock.
静脉-动脉体外膜肺氧合（VA-ECMO）可稳定导致心源性休克的电风暴中的血流动力学。然而，VA-ECMO的不良反应是由于逆行血液回流导致左心室（LV）后负荷和LV舒张末期压力增加。通过插入Impella进行左心室卸载可改善这些不良反应。本病例说明了在VA-ECMO机械支持下心源性休克对除颤有抵抗的难治性电风暴中，辅助插入Impella可能具有的疗效。
