Thromboembolic and bleeding risks in edoxaban patients with pacemaker and cardiac monitoring procedures: Outcomes of the Global EMIT program

Introduction Limited data were published on the management of direct oral anticoagulants in the insertion of pacemaker and cardiac monitoring devices. This study describes the management and outcomes of edoxaban, a direct oral factor Xa inhibitor, in patients undergoing pacemaker or monitoring device implantation in routine clinical practice. Methods and Results EMIT-AF/VTE collected data of patients from Europe, Korea, and Taiwan. Timing and duration of periprocedural interruption of edoxaban were at the treating physician's discretion. Pacemakers or monitoring devices were implanted into 136 patients who were evaluated from 5 days pre- until 30 days post-procedure. The primary outcomes were the incidences of acute thromboembolic events (ATE), ischemic events, and International Society on Thrombosis and Haemostasis-defined Major Bleeding; secondary outcomes included incidence of clinically relevant non-major bleeding (CRNMB) and perioperative edoxaban interruption times. Conformance with European Heart Rhythm Association (EHRA) Guidance on interruption of direct oral anticoagulant therapy was variable: of the cardiac monitoring device patients, where no interruption of therapy would be expected, nonetheless, 62.5% had interruption of treatment, whereas in pacemaker procedures, where interruption would be expected, 23.4% had no interruption. No ATE or ischemic events occurred. One case of CRNMB and two of minor bleeding occurred. All bleedings occurred more than 3 days after the procedure. Conclusion/Relevance The periprocedural complication risk for edoxaban treated patients undergoing pacemaker or invasive cardiac monitoring implantation was low. This population of patients was well managed in routine practice.
