Abstract
Introduction: Pacemaker pocket erosion is an uncommon delayed complication of the cardiac implantable electronic device (CIED) implantation that most frequently occurs in frail and elderly patients. We present a case of such a patient who developed pacemaker pocket erosion after being initiated on hormonal therapy for advanced prostate cancer. Case presentation: The patient is a ninety-three-year-old male with a history of persistent atrial fibrillation and dual chamber pacemaker in situ with last generator change two years prior presented with a two-week history of pacemaker wound dehiscence and exposed pacemaker. Six months earlier, the patient was diagnosed with advanced prostate cancer, was initiated on gonadotropin-releasing hormone agonist, leuprolide, and subsequently developed unintentional weight loss of 30 pounds. For two months prior to the current presentation, the patient noticed subjective discomfort at the site of the pacemaker pocket which he did not report to his cardiologist and eventually developed an erosive wound overlying the pacemaker pocket exposing the device (Image 1). He was admitted to the hospital and found to be hemodynamically stable, without leukocytosis and, negative blood cultures. Transthoracic and transesophageal echocardiograms showed no evidence of vegetation. He was empirically treated with daptomycin and was referred for pacing system extraction. He underwent pacing system replacement with leads and device extraction followed by leadless Micra VR (Medtronic, Minneapolis, MN) pacemaker implantation. Following a 4-week antibiotic course post pacemaker system extraction, the pacemaker pocket wound was fully healed. Conclusions: Aging and weight loss are known major risk factors for device-pocket erosion and externalization of the CIED. It highlights the importance of improving awareness of this entity and that initiation of hormonal therapy can be a contributing factor to such complications.
