Ashley Elizabeth Prosper MD, Presenter: Nothing to Disclose

Michael David Katz MD, Abstract Co-Author: Nothing to Disclose

• Review the mechanics of Left Ventricular Assist Devices (LVADs) & their effects on cardiovascular physiology • Discuss the multiple risk factors for bleeding in patients with LVADs • Review the most likely sites of gastrointestinal bleeding in patients with LVADs • Discuss an approach to the evaluation of gastrointestinal bleeding in LVAD patients and how IR plays a role 

• Schematic review of LVADs and their mechanics • Discussion of altered perfusion in patients with LVADs including continuous flow and decreased pulse pressure • An explanation of coagulopathy in the LVAD patient: anticoagulation, decreased vWF, platelet  destruction and angiodysplasia • A stepwise approach to evaluating GI bleeding in LVAD patients • Selected angiographic case review from our institution • When to consider empiric embolization
