Key result
A 50-year-old male developed Twiddler's syndrome 4 weeks after subcutaneous-ICD implantation, presenting with an inappropriate shock and lead dislodgement requiring revision.
Why the study?
Twiddler syndrome is reported in transvenous devices, but there is a paucity of data on subcutaneous devices.
Population
A 50-year-old male with hypertrophic cardiomyopathy and non-sustained ventricular tachycardia undergoing S-ICD implantation
Design
Case report
Follow-up
4 weeks

Twiddler's syndrome warrants consideration in S-ICD patients with inappropriate shocks; this case leaves open its incidence and prevention strategies.
Case Report (n=1)
Twiddler's syndrome, a rare complication involving device displacement, can occur with subcutaneous ICDs and present with inappropriate shocks and abnormal lead impedance.
Jin et al. (2020) conducted a case report in Hypertrophic cardiomyopathy and non-sustained ventricular tachycardia (n=1). Subcutaneous-ICD (S-ICD) implantation was evaluated on Twiddler's syndrome (lead dislodgement). A 50-year-old male developed Twiddler's syndrome 4 weeks after subcutaneous-ICD implantation, presenting with an inappropriate shock and lead dislodgement requiring revision.
