Implanting a gold-coated cardioverter-defibrillator as a solution to cardiac implantable device hypersensitivity: a case report

Hypersensitivity to CIED materials is an important differential diagnosis in cases of recurrent pocket inflammation with negative microbiological findings. Due to overlapping local symptoms, it is frequently mistaken for infection, leading to delayed or inappropriate management. A detailed allergy history and use of skin patch testing are essential in guiding diagnosis. Once confirmed, conservative measures such as corticosteroids have limited value, and definitive treatment requires full system explantation. Reimplantation with a hypoallergenic device-such as a gold-coated generator-represents an effective therapeutic strategy.
