Implication
Female sex, access site, and prior failure predict higher Fidelis lead failure risk; hypothesis-generating for risk-stratified surveillance pending prospective data.

Intervention
Sprint Fidelis lead implantation

Outcome
Lead failuresafety
Fidelis lead failure rates continue to accelerate over time, with female sex, subclavian/axillary access, and prior lead failure being significant predictors, suggesting replacement should be considered at generator change.
