title: Erosion of implantable cardioverter defibrillator patch electrode into airways: an unusual cause of recurrent hemoptysis.
abstract: A 74-year-old man presented with a 9-month history of recurrent hemoptysis. He had implantable cardioverter defibrillator (ICD) patch electrodes placed 4 years before. A chest x-ray film showed crinkling of his posteriorly placed ICD patch which also appeared to have separated from his ventricle on a CT scan of the chest. Bronchoscopy localized the ICD patch electrode to the lower lobe of the left lung. He underwent a lobectomy and was treated with antibiotics at home. In patients with known ICD implantation, patch erosion into the airways should be considered in the differential diagnosis of recurrent hemoptysis.
