Abstract:
:The pandemic of heart failure and the limited options for treatment of end-stage disease have resulted in an increase in the utilization of left ventricular assist devices (LVADs). Improvements in device technology and patient survival have led to an expanding population of patients requiring noncardiac surgery while on LVAD therapy, thus leading to a growing need for familiarity with the physiology of these patients. This review describes the functional mechanics of the most prevalent continuous-flow LVAD, the HeartMate II, and focuses on perioperative anesthetic concerns.
