Abstract

PurposeAntithrombotic therapy is essential in LVAD recipients and must be carefully titrated in each patient. Different devices might influence the coagulation system differently. An awareness of this may allow early planning of the most appropriate antithrombotic approach according to LVAD type. We studied the impact of two different continuous flow LVADs on the coagulation system: Jarvik 2000, an axial flow pump, versus HeartWare HVAD, a magnetically levitating centrifugal pump.Methods and MaterialsResults of platelet count, thromboelastometric and aggregometric tests were compared between 13 patients with Jarvik and 8 patients with HeartWare, all implanted in our center between 2008 and 2..
