The use of pacemakers and implantable cardioverterdefibrillators continues to increase for the management of cardiac dysrhythmias and, more recently, heart failure. Long-term complications associated with their use include infection, lead failure, and spurious shocks. Although the risk of infection with intracardiac devices is well known, the clinical presentation of this complication can be insidious, delayed in onset, and difficult to diagnose. We report a case of Aspergillus fumigatus infection of an implantable cardioverter-defibrillator with right-sided endocarditis in a 55-year-old man. The infection presented as persistent pulmonary infiltrates (due to recurrent septic pulmonary embolism) and anemia more than 2 years after implantation of the device. Clinicians should be aware of the variable manifestations resulting from infection of intracardiac devices.
