Infection of retained defibrillator lead fragment after heart transplant | Clinics and Practice

A 59-year old heart transplant recipient was admitted due to continuous pain in her left axilla. A purulent collection was found at the site of prior defibrillator placement, where a remnant proximal segment of an electric lead was found. Two years before, the patient had had pocket infection treated with revision, but without device extraction. The remnant lead was eventually removed transvenously without complications. This is the first description of infection complicating retention of lead fragments after heart transplant. The role of biofilm and net immune state on the persistence and late recurrence of infection is discussed
