Background: The subcutaneous implantable cardioverter defibrillator (S-ICD) is a relatively novel alternative to the transvenous ICD for the treatment of life-threatening ventricular arrhythmias, and is currently used in the clinical practice of several centers. The aim of this analysis was to describe current Italian practice regarding S-ICD implantation and its evolution over the years. Methods: We analyzed 607 consecutive patients (78% male, 48 ± 16 years) who underwent S-ICD implantation in 39 Italian centers from 2013 to 2017.

BACKGROUND: At the time of subcutaneous implantable cardioverter-defibrillator (S-ICD) implantation, successful termination of ventricular fibrillation (VF) is confirmed. A previous study reported cases of prolonged time to therapy during defibrillation testing.
OBJECTIVE: We sought to evaluate the time to therapy, identify possible predictors of delay and investigate the impact of delayed therapy on VF conversion.
METHODS: We analyzed consecutive S-ICD patients who underwent initial conversion testing at a shock energy of 65J in 53 Italian centers.

Aims The traditional technique for subcutaneous implantable cardioverter-defibrillator (S-ICD) implantation involves three incisions and a subcutaneous pocket. Recently, a two-incision and intermuscular (IM) technique has been adopted. The PRAETORIAN score is a chest radiograph-based tool that predicts S-ICD conversion testing. We assessed whether the S-ICD implantation technique affects optimal position of the defibrillation system according to the PRAETORIAN score. Methods We analysed consecutive patients undergoing S-ICD implantation.
