[The subcutaneous implantable cardioverter-defibrillator in clinical practice]

Abstract

Overcoming lead-related complications, the subcutaneous implantable cardioverter-defibrillator (S-ICD) represents the greatest advancement in the management of patients with ventricular arrhythmias and the prevention of sudden cardiac death. Due to the absence of leads within the body, the S-ICD requires an innovative approach for sensing of subcutaneous signals and defibrillation. The aim of this review is to analyze the current evidence regarding patient selection, technical aspects such as the implant technique, programming and follow-up, as well as complications and troubleshooting of this innovative technology.
