Incomplete Lead Removal During the Extraction Procedure: Predisposing Factors and Impact on Long-Term Survival in Infectious and Non-Infectious Cases: Analysis of 3741 Procedures.

1. Non-removable LRs are encountered in 4.17% of patients. 2. CIED infection has no influence on retention of LRs, but younger patient age, multiple CIED-related procedures and higher levels of procedure complexity are independent risk factors for the presence of LR. 3. Better survival outcomes following TLE in patients with LRs are not the effects of their presence but younger patient and better health status.
