Mechanical Circulatory Support in the Cardiac Catheterization Laboratory for Cardiogenic Shock.

Despite the development of acute revascularisation, the mortality rate for cardiogenic shock remains around 50%. Mechanical circulatory support devices have long held promise in improving outcomes in shock, but high-quality evidence of benefit has not been forthcoming. In this article we review the currently available devices for treating shock, their physiological effects and the evidence base for their use in practice. We subsequently look ahead within this developing field, including new devices and novel indications for established technology.
