Chronic phase subcutaneous implantable cardioverter defibrillator lead dislodgement in a patient with arrhythmogenic right ventricular cardiomyopathy

The subcutaneous implantable cardioverter defibrillator (S-ICD) is often used in young patients such as arrhythmogenic right ventricular cardiomyopathy (ARVC) and Brugada syndrome due to long-term lead durability issues. Although S-ICD lead dislodgement is rare, we encountered such an incident in a young ARVC patient during the chronic phase following the two-incision technique. Remote monitoring system is useful for early diagnosis of electrode movement (Graphical abstract image). When S-ICD lead dislodgement occurs in active young patients, lead revision using the three-incision technique may be an option.
