Subcutaneous implantable cardioverter defibrillators (S-ICDs) are currently indicated for patients who meet ICD implantation criteria for the prevention of sudden cardiac death (SCD). In December 2020, a unique cardiac implantable electronic device (CIED) situation arose as both the S-ICD generator and electrode were under a device advisory. We would recommend all future CIED implantation guidelines receive a caveat regarding checking current CIED advisories, in order to avoid future similar scenarios.
