Cardiac implantable electronic devices (CIEDs) – cardiac pacemakers and implantable cardioverter defibrillators –are an established treatment for the management of cardiac dysrhythmias in millions of patients. Complications occur in up to 15%, some of which may present first to the dermatologist.
The differential (caused by local venous obstruction and pressure dermatitis), and impending skin erosion/device extrusion.
Erosion and extrusion is a major complication with significant morbidity and mortality. The two main causes are pressure necrosis and infection. Pressure necrosis is influenced by the size of the device, complexity of the connections, and technical skill with which the pacemaker chest wall pocket is created.
After extrusion, the pacemaker should be considered contaminated and removed, and the necrotic tissue debrided. If infected, a prolonged course of appropriate antibiotic therapy is indicated. A bacterial culture in the patient presented here was negative.
Pocket infection of CIEDs is rare and may manifest as erythema, tenderness, drainage, erosion, or pruritus above the site of the pacemaker, along with systemic symptoms and signs, including fever, chills, or malaise. Some may have just the systemic symptoms. Fewer than half of patients with CIED infection present within 1 year of their last procedure.
Ruptured epidermal cysts usually manifest as acute swelling, inflammation, and tenderness of previously long-standing asymptomatic epidermal cysts. There may be drainage of malodorous keratinous and purulent debris. They are typically not infected. Treatment includes incision and drainage for fluctuant lesions or intralesional corticosteroid injection for early, nonfluctuant cases.
Allergic contact dermatitis to metal may be seen with implantable devices. Patch testing to various metal allergens can be helpful in determining if any allergy is present.
