Background
Anticoagulation with vitamin K antagonists is vital to prevent pump thrombosis in patients with left ventricular assist devices (LVADs). However, the safety and efficacy of bridging anticoagulation for the routine management of subtherapeutic international normalized ratio (INR) in stable outpatients remains poorly characterized.
Methods
In this retrospective study, a total of 60 LVAD outpatients had 110 episodes of subtherapeutic INR noted on routine testing. 34 of these episodes were managed with parenteral bridging anticoagulation and 76 were managed with only an adjusted dose of warfarin. The rates of bleeding and thromboembolic adverse events following these episodes of subtherapeutic INR …

The VAD Journal
The use of left ventricular assist devices (LVAD) provides a treatment strategy for advanced heart failure patients to prolong life and serve as a mediator (bridge to transplant) until an organ becomes available in patients considered suitable candidates for heart transplantation. The use of LVAD therapy is complicated by the constant risk of bleeding and thrombotic events. We reviewed and analyzed the effectiveness of our current heparin protocol with respect to overall anticoagulation and time in therapeutic range (TTR). Our analysis demonstrated that patients did not achieve therapeutic anticoagulation for at least 24 hours following initiation of heparin and that …
