On examination, he appears fatigued with a heart rate of 130 in sinus tachycardia. A transthoracic echocardiogram demonstrates LVAD inflow and outflow cannulas in the appropriate position and normal position of the interventricular septum. The LVAD controller is showing a low-flow alarm and a decreased pulsatility index.
