Heart transplantation (HTx) represents the "gold standard" in end-stage heart failure therapy. Due to their severe heart failure and for prevention of sudden cardiac death, the majority of patients presenting for HTx will have a history of an implanted cardioverter-defibrillator (ICD). Usually, within the scope of HTx, all cardiac-implanted electronic device components are removed. In rare cases these efforts fail and some material remains. The abandoned lead fragments can cause serious complications. The case presented herein involves a patient with recurrent bacteremia after successful HTx originating from an abandoned and infected lead fragment. In 2016, a 64-year-old man received a donor heart transplant due to end-stage heart failure. Unfortunately, during the procedure, not all components of an ICD implanted in 2007 could be removed. An initially event-free period was followed by recurrent fever attacks and staphylococcal bacteremia was diagnosed. After an extensive search, the source of the bacteremia was identified by positron emission tomography-computed tomography (PET-CT), and percutaneous extraction of the abandoned and infected ICD lead fragment was scheduled. The fragment was extracted using a minimally invasive approach via percutaneous femoral vein access. The patient was discharged 3 days later, with no further complications. This case highlights the need for conscientious and complete removal of foreign material in the HTx setting. Difficult-to-diagnose sources of infection could be reliably identified by PET-CT. When required, extraction of the foreign body should be done using a minimally invasive approach.
