Salvage of permanent epicardial lead function by conversion of a bipolar to unipolar lead.

ABSTRACT

Increased thresholds in permanent epicardial leads pose a special challenge in the postoperative period. We present a case of complete heart block after surgical correction of a congenital heart defect that required conversion of an axial bipolar lead to unipolar lead to avoid lead replacement. We review the options for repair and describe our approach to this patient.
