Does implantation of a subcutaneous array improve defibrillation thresholds in patients with ICD distal coil failure?
Implantation of a subcutaneous array may offer a solution for high defibrillation thresholds due to distal coil failure, avoiding the need for high-risk lead extraction.
Avitall et al. (2003) studied this question.
