Key result
Endocardial pacing leads in older patients (≥65 years) and in the atrial position had fewer verified structural failures (P=0.014 and P=0.007, respectively).
Why the study?
What is the long-term performance and what factors are associated with structural failure of endocardial pacing leads?
Population
2,611 endocardial pacing leads implanted between 1980 and 1991 with at least 1 month of follow-up
Design
Cohort
Follow-up
up to 10 years (minimum 1 month)

May inform age- and position-specific lead selection; extends historical survival data but remains hypothesis-generating.

What is the long-term performance and what factors are associated with structural failure of endocardial pacing leads?
Endocardial pacing leads demonstrate excellent long-term survival, though performance varies by patient age, implant position, and specific lead model.
Helguera et al. (1994) conducted a cohort in Endocardial pacing lead structural failure. Endocardial pacing leads was evaluated on Structural lead failure (suspected and verified). Endocardial pacing leads in older patients (≥65 years) and in the atrial position had fewer verified structural failures (P=0.014 and P=0.007, respectively).
