Pulmonary Emboli from a Platelet‐rich Thrombus Attached to a Pacemaker Electrode

Abstract
A patient with recurrent, fatal pulmonary emboli originating from thrombus attached to a permanently‐implanted pacemaker electrode is described. While most throm‐boemboli are composed predominantly of fibrin and erythrocytes. histologic and immunologic studies showed this thrombus to be rich in platelets. A possible therapeutic approach to this rare situation is discussed.
