Key result
Modified transvenous steroid lead maintains stable low pacing thresholds over ~3 years as an epi-intramyocardial electrode.
Why the study?
Excessive surface fibrosis or fat limits effective electrode insertion in patients requiring epicardial pacing, necessitating alternative approaches.
Case Report (n=1)
A modified transvenous steroid lead used as an epi-intramyocardial electrode provided stable low implant thresholds over 3 years in a patient with a univentricular heart.
May offer pacing option in univentricular hearts; leaves open need for prospective validation of durability and safety.
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.

Karpawich et al. (1998) conducted a case report in Univentricular heart requiring epicardial pacing (n=1). Modified transvenous steroid lead used as an epi-intramyocardial electrode was evaluated on Implant threshold values. A modified transvenous steroid lead used as an epi-intramyocardial electrode maintained stable low implant threshold values over a 3-year postimplant interval.
