ReviewPercutaneous Mechanical Circulatory Support Devices in Cardiogenic Shock.
Despite a high rate of early revascularization and use of intra-aortic balloon pump counterpulsation therapy, the prognosis of patients with cardiogenic shock has remained poor. In the hopes of improving outcomes, clinicians are increasingly turning to percutaneous left and right mechanical circulatory support devices. Until recently, the evidence base for these devices had consisted only of observational data, meta-analyses, and small feasibility trials. ⋯ We then use this discussion to provide clinicians with a useful framework for understanding when selecting between or while managing patients with a percutaneous mechanical circulatory support devices. We critically review the recently published data for and against the use of commercially available devices-the intra-aortic balloon pump counterpulsation, the Impella system, the TandemHeart, and venous-arterial extracorporeal membrane oxygenation-and highlight gaps in our understanding. Given such gaps, a consensus multidisciplinary approach that combines expertise from interventional cardiologists, heart failure specialists, cardiac surgeons, and cardiac anesthesiologists may help pair the right patient with the right device at the right time.
