Dynamic left ventricular outflow tract obstruction is a rare cause of cardiogenic shock after an acute myocardial infarction. A case is presented where inotropic support and an intra-aortic balloon pump aggravated the cardiac hemodynamics by this mechanism. The circulatory support provided by Impella 2.5 heart pump, in addition to discontinuation of inotropic support and intra-aortic balloon pump, allowed stabilization and successful percutaneous revascularization.
动态左心室流出道梗阻是急性心肌梗死后心源性休克的罕见病因。本文报告了一例因正性肌力支持和主动脉内球囊反搏加重该机制导致心功能恶化的病例。除停用正性肌力支持和主动脉内球囊反搏外，Impella 2.5 心脏泵提供的循环支持还可稳定病情并成功进行经皮血运重建。
