Radiographic and electrocardiography-gated noncontrast cardiac CT assessment of lead perforation: modality comparison and interobserver agreement.

Background: Pacemaker or implantable cardioverter-defibrillator lead extraction may be required because of infection, malfunction, or breakage. The preprocedural identification of lead tip position may help ensure safe performance of the procedure.

Objective: To analyze the ability of chest radiography and CT imaging to characterize lead tip position and identify perforation in a population of patients who underwent lead extraction.
