title: Migration and infection of a pace-sense lead from an abdominal defibrillator system.
abstract: A 47-year-old man had an ICD system with epicardial and endocardial components and an abdominal generator placed in 1990 following a cardiac arrest. Ten years later his BT10 lead was amputated due to an insulation defect, and he received a new pectoral generator with transvenous leads. A few months later he developed fevers, chills, and bacteremia. Evaluation demonstrated migration of the entire BT10 lead into the right atrium. Complete surgical explantation was required and the bacteremia resolved. This case illustrates the importance of solid anchoring of distal lead components following generator removal and the potential complication of intravascular lead migration.
