“…Up to now, all described insulation defects at the level of the tricuspid valve occurred in Riata leads with silicone insulation. Abrasions of ICD leads with silicone insulation are known to be prone to insulation failure 9 . Newer generations of the Riata lead family (e.g., model numbers 7020 or 7030) as well as the succeeding models of the Durata lead family have Optim ® insulation.…”

“…Mewis et al reported a high incidence of insulation defects (12%) in silicone lead systems (CPI Endotak C models 0064 and 0072) that required operative revisions during a mean follow-up of 23.8Ϯ10.9 months. 21 Abrasion of ICD lead insulation material was a frequent finding in silicone leads during generator replacement in a study by de Lurgio et al 22 After an average lead implant duration of 53Ϯ18 months, 79% of silicone leads showed abrasions, whereas only 1 of 11 polyurethane leads was affected.…”

Background— The number of patients with longer follow-up after implantation of an implantable cardioverter-defibrillator is increasing continuously. Defibrillation lead failure is a typical long-term complication. Therefore, the long-term reliability of implantable cardioverter-defibrillator leads has become an increasing concern. The aim of the present study was to assess the annual rate of transvenous defibrillation lead defects related to follow-up time after lead implantation. Methods and Results— A total of 990 consecutive patients who underwent first implantation of an implantable cardioverter-defibrillator between 1992 and May 2005 were analyzed. Median follow-up time was 934 days (interquartile range, 368 to 1870). Overall, 148 defibrillation leads (15%) failed during the follow-up. The estimated lead survival rates at 5 and 8 years after implantation were 85% and 60%, respectively. The annual failure rate increased progressively with time after implantation and reached 20% in 10-year-old leads ( P <0.001). Lead defects affected newer as well as older models. Patients with lead defects were 3 years younger at implantation and more often female. Multiple lead implantation was associated with a trend to a higher rate of defibrillation lead defects ( P =0.06). The major lead complications were insulation defects (56%), lead fractures (12%), loss of ventricular capture (11%), abnormal lead impedance (10%), and sensing failure (10%). Conclusions— An increasing annual lead failure rate is noted primarily during long-term follow-up and reached 20% in 10-year-old leads. Patients with lead defects are younger and more often female.

“…33 Nowadays, because the majority of current leads use silicone rubber as insulation, insulation should not be a ground for differences in event rates. Even though at elective abdominal device replacement Lurgio et al 34 describe 79% abrasion lesions in silicone-coated leads, this sporadically resulted in lead malfunction.…”

Background-Despite the positive effect on mortality in selected patients, implantable cardioverter-defibrillator therapy is also associated with potential malfunction of the implanted system. The present study provides the long-term lead failure rate in a large single-center cohort. Methods and Results-Since 1992, a total of 2068 implantable cardioverter-defibrillator patients with 2161 defibrillation leads were prospectively collected. Data of the implant procedure and all follow-up visits were recorded. All cases of lead removal or capping or placing of an additional pace or sense lead were noted and analyzed. Lead models were grouped by manufacturer and approximate lead diameter in French. During a mean follow-up of 36 months, 82 (3.8%) cases of lead failure were identified. Cumulative incidence of lead failure at 1 year was 0.6%; at 5 years, 6.5%; and at 10 years, 16.4%. The highest risk of lead failure was found in small-diameter leads. Adjusted hazard ratio was 6.4 (95% CI, 3.2 to 12.8) for Medtronic 7F leads, when compared with all other leads. Conclusions-In this large single-center experience, the overall incidence of lead failure was 1.3 (95% CI, 1.0 to 1.6) per 100 lead-years.
