Why the study?
Does the addition of steroid elution or reduction of tip surface area improve pacing performance and lower current drain in patients receiving atrial pacing leads?
Population
30 patients (10 per group) receiving atrial pacing leads and identical pulse generators
Comparison
BS45D lead or S44F lead vs S84F lead (8 mm2 tip)
Design
Cohort
Follow-up
1 year

Lower thresholds with steroid-eluting leads did not reduce drain; supports elution benefit but leaves open impact on atrial lead longevity.
Does the addition of steroid elution or reduction of tip surface area improve pacing performance and lower current drain in patients receiving atrial pacing leads?
The addition of steroid elution to a 4 mm2 tip atrial pacing lead significantly lowers long-term pacing thresholds, although this does not translate to lower current drain of the pacing system.
