Abstract

Pacemaker endocarditis has a high rate of morbidity and mortality and is associated with substantial health-care cost. To maximize the effectiveness of treatment, diagnosis of pacemaker endocarditis should be made as early as possible. Medical treatment alone is not successful, and the removal of the entire artificial pacing system is often required. We present a case of a female patient with a permanent transvenous pacemaker, recurring episodes of fever and chills, general malaise, and a computed tomography image of a solitary tumor-like lesion indicating pneumonia. The symptoms subsided with empirical antibiotics but without improvement in the radiologic images. A wedge resection of the lesion by thoracotomy was performed, revealing a necrotic lung lesion compatible with pulmonary infarct. Transesophageal echocardiography showed a mass that was adherent to the pacemaker lead. The therapeutic approach consisted of surgical removal of the complete pacing system along with long-term antibiotic therapy and implantation of a new device with an epicardial lead. Serial follow-up echocardiograms for a 1-y period did not show any recurrence, and the subsequent course was uneventful.
