Chronic performance of a transvenous steroid pacing lead used as an epi-intramyocardial electrode.

Excessive surface fibrosis or fat limits effective electrode insertion in patients requiring epicardial pacing. We present chronic performance of a modified transvenous steroid lead used as an epi-intramyocardial electrode in a patient following repair of a univentricular heart after failure of both standard and steroid-eluting epicardial leads. Low implant threshold values remained stable during a 3-year postimplant interval demonstrating an effective and innovative approach to epicardial pacing.
