Thromboembolism is a known complication of pacemaker implantation. However, published literature describes only a few cases, in which the events occurred in absence of antithrombotic prophylaxis, not routinely employed for its prevention in current clinical practice. We report a case of pacemaker lead-associated thrombosis in a patient taking continuative oral anticoagulant therapy with edoxaban tosylate (edoxaban). No data in present literature supports the use of anticoagulant prophylaxis for pacemaker lead thrombosis. In our report ongoing treatment with edoxaban proved ineffective for thrombosis prevention. We also discuss the role of three-dimensional transthoracic echocardiography for diagnostic assessment of thrombosis in a fragile patient.
