Answer: Left Ventricular Assist Device (LVAD)
An LVAD is a mechanical pump that pulls blood from the left ventricle and pumps it to the ascending aorta for systemic delivery; LVADs are increasingly being placed in patients with heart failure so you must be aware of them.
The three indications for an LVAD are:
There are several models, which have been implanted in people (http://www.mylvad.com/lvad-devices). The main distinction between devices are pulsatile or non-pulsatile (or linear) flow; newer generation devices are non-pulsatile.
Patients with LVAD may develop complications such as infections, arrhythmias, or anemia, but bleeding can be a life-threatening one; bleeding occurs secondary to an acquired von Willebrand factor deficiency, AVMs within the GI tract, or secondary to over anti-coagulation (typically with Warfarin).
