This is a randomized, prospective clinical trial comparing 2 different types of implantable cardioverter defibrillator (ICD) leads in children and patients with congenital heart disease. ICD lead survival in this patient group is particularly suboptimal, and lead extraction is technically difficult and carries a substantial morbidity risk. Recently, improved ICD lead designs have been released and are currently being utilized in patients. The main aim of the study is to determine if either type of lead performs better in terms of implantation electrical characteristics, long-term survival without breaking, and ease of extractability.
