Clinical experience of entirely subcutaneous implantable cardioverter-defibrillators in children and adults: cause for caution

This paper describes our clinical experience of using an entirely subcutaneous implantable cardioverter–defibrillator (S-ICD) in children and adults. Maintaining lead integrity and long-term vascular access are critical challenges of ICD therapy, especially in younger patients. The S-ICD has considerable theoretical advantages in selected patients without pacing indications, particularly children and young adults. Although sensing in an S-ICD...
