Why the study?
Prior S-ICD cohorts had less heart disease and fewer comorbidities than standard ICD populations, leaving acute performance uncharacterized in primary prevention patients with LVEF ≤35%.
Does subcutaneous implantable cardioverter-defibrillator (S-ICD) implantation have high acute success and low perioperative complication rates in primary prevention patients with LVEF ≤35%?

S-ICD acute performance in higher-comorbidity primary-prevention LVEF ≤35% patients needs confirmation; this cohort study leaves open generalizability to broader populations.
Does subcutaneous implantable cardioverter-defibrillator (S-ICD) implantation have high acute success and low perioperative complication rates in primary prevention patients with LVEF ≤35%?
S-ICD implantation demonstrates high procedural success and low perioperative complication rates in a higher-risk primary prevention cohort with LVEF ≤35%, though higher BMI warrants careful implant technique.
