What is the annual rate of transvenous defibrillation lead defects in ICDs over a period of >10 years?
Transvenous defibrillation leads demonstrate a significant progressive failure rate over time, reaching 20% at 10 years, highlighting the need for vigilant long-term monitoring, especially in younger and female patients.
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.
Kleemann et al. (Mon,) studied this question.
