Cardiogenic shock: From ECMO to Impella and beyond.

For patients in cardiogenic shock, several devices can serve as a "bridge," ie, provide circulatory support and allow the patient to live long enough to recover or to receive a heart transplant or a long-term device. Options include an intra-aortic balloon pump, TandemHeart, Impella, extracorporeal membrane oxygenation (ECMO), and CentriMag. Which device to use depends on individual patient needs, local expertise, and anatomic and physiologic considerations.
