Twelve Hours of Sustained Ventricular Fibrillation Supported by a Continuous‐Flow Left Ventricular Assist Device

Left ventricular assist device (LVAD) therapy improves survival and quality of life by mechanically unloading the left ventricle and maintaining hemodynamics in patients with end‐stage heart failure. LVADs can also be lifesaving by maintaining hemodynamics during ventricular arrhythmia. Continuous‐flow LVADs have become the preferred LVAD technology. As presented here, a continuous‐flow LVAD successfully provided hemodynamic support to a patient in sustained ventricular fibrillation for over 12 hours when the internal defibrillator was unable to terminate the arrhythmia. This case demonstrates that continuous‐flow LVADs can be lifesaving in the setting of otherwise certain hemodynamic collapse from sustained ventricular fibrillation. (PACE 2012; 35:e144–e148)
