S-ICD implantation appears safe and feasible in Japanese patients, though careful follow-up is required to manage T-wave oversensing and prevent inappropriate shocks.

Supports S-ICD feasibility in Japanese patients; leaves open need for larger confirmatory trials.
BACKGROUND: The subcutaneous implantable cardioverter-defibrillator (S-ICD) is recognized as a viable alternative to the transvenous ICD. The safety and efficacy of this device has been demonstrated in Western countries, but studies with S-ICD implantation in Japanese patients have not been reported. METHODS AND RESULTS: Twelve patients received an S-ICD implant in our institute between February and September 2016. All S-ICDs were successfully implanted without complications. One appropriate and one inappropriate therapy was identified. CONCLUSIONS: S-ICD implantation appears to provide a viable alternative to transvenous ICD implantation for some Japanese patients. However, we should perform careful follow-up of patients to eliminate inappropriate therapy.
