Cessation of Anticoagulation for Bleeding and Thrombosis Events with a Fully Magnetically Levitated Centrifugal Left Ventricular Assist Device
Anticoagulation therapy for patients supported by a left ventricular assist device (LVAD) has not been adequately evaluated in relevance to newer pumps, such as the fully magnetically levitated HeartMate 3 pump. Current anticoagulation guidelines target a goal INR of 2.0 –3.0 with vitamin K antagonists to mitigate the risk of pump thrombosis and ischemic stroke, but are based on historical trials with older devices. Long-term outcomes associated with newer devices, such as the centrifugal-flow HeartMate 3 (HM3), have demonstrated a marked decrease in the incidence of pump thrombosis compared to mechanical bearing axial-f...

Cessation of anti-coagulation for bleeding and subsequent thrombosis events with a fully magnetically levitated centrifugal left ventricular assist device
Anti-coagulation therapy for patients supported by a left ventricular assist device (LVAD) has not been adequately evaluated in relevance to newer pumps, such as the fully magnetically levitated HeartMate 3 (HM3) pump. Current anti-coagulation guidelines target a goal international normalized ratio (INR) of 2.0 to 3.0, with vitamin K antagonists to mitigate the risk of pump thrombosis and ischemic stroke, but are based on historical trials with older devices. Long-term outcomes associated with newer devices, such as the centrifugal-flow HM3, have demonstrated a marked decrease in the incidence of pump thrombosis compared w...
