Favorable Effects of Impella on Takotsubo Syndrome Complicated with Cardiogenic Shock.

Reportedly, approximately 9.9%-12.4% of patients with Takotsubo syndrome (TTS) are complicated with cardiogenic shock (CS) and its prognosis remains poor even with the support of conventional mechanical circulatory assist devices including intra-aortic balloon pumping and venoarterial extracorporeal membrane oxygenation. Impella, a novel percutaneous left ventricular assist device, provides strong circulatory support together with the unloading of the left ventricle, and it is theoretically a promising mechanical circulatory assist device for TTS. In this case study, we report four consecutive patients with TTS complicated with CS who were successfully resuscitated using the Impella support.
