Background: Subcutaneous implantable cardioverter defibrillator (S-ICD) system has been proven to be an effective therapy for prevention of sudden cardiac death (SCD) in selected patients. Although the Shockless IMPLant Evaluation (SIMPLE) trial has shown that defibrillation threshold (DFT) testing is not necessary for transvenous ICD (TV-ICD) systems, it is still recommended for S-ICD systems. We aimed to study the efficacy and safety of S-ICD implantation without DFT in our Heart Center with the comparison of S-ICD patients' outcome to those with a single chamber TV-ICD without DFT in the same period...

OBJECTIVES: The subcutaneous implantable cardioverter defibrillator (S-ICD®) has been established as an alternative to conventional transvenous ICD for the prevention of sudden cardiac death. Initial studies have shown safety and efficacy of the system with a left parasternal (LP) electrode. However, several case studies reported a right parasternal (RP) position. The purpose of this study was to analyze shock efficacy and safety of an RP electrode position. METHODS: Between June 2010 and May 2016, 120 S-ICD® were implanted at our institution...

The eligibility for subcutaneous implantable cardioverter-defibrillators (S-ICD) was assessed among patients already implanted with cardiac resynchronization therapy (CRT). We included 20 patients (15 men, age 73±10years, LVEF 35±10%). Seventeen (85%) patients were eligible for S-ICDs: 11 (55%) patients on only 1 vector and 6 (30%) patients on 2 or 3 vectors. Patients who were eligible on 2-3 vectors had narrower paced QRS than patients who were not eligible or were eligible on only one vector (133±18ms vs 167±17ms, p=0...

INTRODUCTION: Hypertrophic cardiomyopathy (HCM) is a heterogeneous disease associated with sudden cardiac death (SCD) mainly due to ventricular tachycardia (VT) or fibrillation even though life-threatening bradycardia occurs. Risk stratification takes several variables into consideration including non-sustained VT (NSVT). An implantable cardioverter defibrillator effectively prevents SCD.Atrial fibrillation (AF) is common among patients with HCM and warrants anticoagulation even without conventional risk factors according to European guidelines...

Defibrillation threshold (DFT) testing is an important part of ICD implantation. After placement of the ICD generator, a DFT test is performed to evaluate the integrity of the ICD system and to confirm a successful defibrillation safety margin. More than 6% of ICDs implanted are not within the DFT safety margin. Presently described is the case of a patient with a high DFT and some of the methods that can be used to manage this circumstance, including the use of a subcutaneous array.

Patients with reversible cardiac impairment may be, at least temporarily, at high risk of SCD and may go unprotected for considerable time. A less-invasive definitive or bridge solution is the implantation of a subcutaneous cardioverter-defibrillator (S-ICD). The less invasiveness of this procedure ensures easy removal of the system without exposing the patient to the risk of complications.

INTRODUCTION AND OBJECTIVES: The subcutaneous implantable cardioverter-defibrillator (S-ICD) has emerged as an alternative to the transvenous defibrillator. The incidence of complications is similar, with inappropriate shocks (IS) being more frequent than those occurring with contemporary programming of transvenous defibrillators. Several improvements have been implemented after the S-ICD was approved for use in Europe in 2009. This study reports the results of S-ICD use in a single center, whose experience began late, at the end of 2013...

With the advent of "wireless" endocardial pacing, the subcutaneous implantable cardioverter defibrillator, and leadless pacemakers comes an added layer of complexity to the perioperative management of cardiovascular implantable electronic devices (CIED). Since no formal recommendations currently exist for these new CIED technologies, preoperative identification of these devices, understanding their functionality, and developing an individualized perioperative management plan are imperative for the anesthesiologist...

BACKGROUND: Subcutaneous implantable cardioverter-defibrillators provide an alternative to transvenous defibrillation but require higher shock outputs and offer no antitachycardia pacing. The Substernal Pacing Acute Clinical Evaluation (SPACE) study evaluated the feasibility of pacing from an extravascular substernal location. OBJECTIVES: The primary purpose of the SPACE study was to characterize pacing from the substernal space. Secondary objectives included evaluating extracardiac stimulation and recording electrograms...

REVIEW
Jonathan Weinstock, Christopher Madias
The transvenous implantable cardioverter-defibrillator (ICD) has been shown in multiple studies to be effective in the prevention of sudden cardiac death in select populations. The Achilles heel of traditional ICD technology has been the transvenous lead. The subcutaneous ICD provides effective sudden death protection while avoiding lead-related complications of traditional transvenous systems. The subcutaneous ICD is a reasonable option for patients with an ICD indication who do not need bradycardia pacing or cardiac resynchronization therapy...

The advent of the subcutaneous implantable cardioverter-defibrillator (SQ-ICD) provides an alternative to transvenous and epicardial ICD therapy. Particularly germane to the young patient with congenital heart disease or inheritable arrhythmia syndromes, the SQ-ICD may be ideal for those who do not require permanent cardiac pacing. The serious complications associated with transvenous ICD systems are largely driven by the intravascular components of these devices and are avoided by this extravascular technique...

BACKGROUND: The perioperative anticoagulation management during subcutaneous implantable cardioverter-defibrillator (S-ICD) implantation is still evolving. OBJECTIVE: The purpose of this study was to assess whether it is safe to perform S-ICD implantation with uninterrupted warfarin. METHODS: This is a single-center retrospective review of patients undergoing S-ICD implantation between October 1, 2012 and June 30, 2017. One hundred thirty-seven patients underwent successful S-ICD implantation during the study period...

INTRODUCTION: In Switzerland, the first implantation of a subcutaneous implantable cardioverter-defibrillator (S-ICD) took place in November 2012. Up until the end of 2016, a total of 111 S-ICDs have been implanted. The aim of this study was to summarise the experience of a tertiary centre in Switzerland and to discuss the results in the context of international registries. METHODS: All patients in whom an S-ICD was implanted between November 2012 and the end of December 2016 at the University Heart Centre Zurich were included in this study...

Aims: Implantable cardioverter defibrillator (ICD) shocks are associated with a subsequent increased risk of death, and an elevation of cardiac enzymes has been measured after defibrillation testing (DFT). In an experimental swine study, subcutaneous ICD (S-ICD) shocks caused less myocardial damage than traditional ICD shocks. The aim of our study was to investigate the association between S-ICD shock and acute cardiac damage in humans, as evaluated by means of sensitive and highly specific circulating biomarkers...
