Circulatory support can be provided by mechanical means when pharmacologic therapies prove insufficient. These devices may be used to stabilize a patient with the goal of recovery of pump failure or as a bridge to a decision regarding further care. Mechanical circulatory support can be classified in terms of the duration of intended support: short-term mechanical circulatory support, intermediate-term mechanical circulatory support, and durable (long-term) mechanical circulatory support. This chapter provides information on the indications, contraindications, postulated mechanisms of action, and complications of these devices. It contains tables listing Parameters used to monitor left ventricular assist device (LVAD) function, LVAD troubleshooting, and LVAD-related complications.
