The subcutaneous implantable cardioverter-defibrillator (S-ICD®, Boston Scientific, Marlborough, MA, USA, previously Cameron Health, San Clemente, CA, USA) represents an important milestone in ICD therapy for prevention of sudden cardiac death (SCD). Since the introduction of the S‑ICD in 2010, the device has undergone further development. Based on the unique feature of an entirely extracardiac implantation, the S‑ICD is able to reduce the common perioperative and long-term complications of the usual endovascular implanted ICD systems...

BACKGROUND: The majority of inappropriate shocks from the subcutaneous implantable cardioverter-defibrillator (S-ICD) are caused by cardiac oversensing. A novel sensing methodology, SMART Pass (SP) aims to reduce cardiac oversensing. OBJECTIVE: To evaluate the effect of SP on shocks in ambulatory S-ICD patients. METHODS: Patients implanted in 2015-2016 and on remote monitoring were included and followed for one year. Shocks were adjudicated by three independent, blinded reviewers as appropriate or inappropriate...

BACKGROUND AND OBJECTIVE: Worldwide adoption of the subcutaneous implantable cardioverter-defibrillator (S-ICD) for preventing sudden cardiac death continues to increase, as longer-term evidence demonstrating the safety and efficacy of the S-ICD expands. As a relatively new technology, comprehensive anesthesia guidance for the management of patients undergoing S-ICD placement is lacking. This article presents advantages and disadvantages of different peri-procedural sedation and anesthesia options for S-ICD implants including general anesthesia, monitored anesthesia care, regional anesthesia, and nonanesthesia personnel administered sedation and analgesia...

PURPOSE OF REVIEW: In the current era of implantable cardioverter-defibrillator procedures, the decision of whether or not to perform defibrillation threshold testing at the time of implantation is now less of a clinical conundrum. In this paper, we summarize this current practice, beginning with the physiology of defibrillation, followed by a review of the salient data, and discussion of specific situations where defibrillation threshold testing remains a clinical consideration. RECENT FINDINGS: Two prospective randomized trials demonstrated no mortality difference and no overall complication rate difference between patients who underwent defibrillation testing at implant compared with patients who underwent no defibrillation testing...

The subcutaneous implantable cardioverter defibrillators (SICD) is an alternative to the transvenous ICD for the prevention of sudden cardiac death (SCD). Multiple studies have shown that the SICD is safe and effective in treating ventricular arrhythmias. While earlier studies mainly enrolled younger patients with channelopathies, more recent reports included patients with "typical" indications for ICD therapy for the prevention of SCD. In this review we summarize the data available to date on the SICD while highlighting its pros and cons...

The trans-venous implantable cardioverter defibrillator (TV-ICD) is effective in treating life-threatening ventricular arrhythmia and reduces mortality in high-risk patients. However, there are significant short- and long-term complications that are associated with intravascular leads. These shortcomings are mostly relevant in young patients with long life expectancy and low risk of death from non-arrhythmic causes. Drawbacks of trans-venous leads recently led to the development of the entirely subcutaneous implantable cardioverter defibrillator (S-ICD)...

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...

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...

In recent years, there has been a significant evolution in the field of cardiovascular implantable electronic devices (CIEDs). Pacemakers can now be leadless, implantable cardioverter defibrillators can be entirely subcutaneous and implantable loop recorders have become miniaturized. Driven by technological advances and an ageing population implant numbers have also steadily increased. These highly prevalent systems are all radio-opaque and are frequently observed on chest radiographs, yet the devices are neither well recognized nor understood...

The implantable cardioverter defibrillator (ICD) is today an indisputable evidence-based treatment for cardiac sudden death both in primary and secondary prevention. However many clinical conditions that would represent an indication to ICD implantation, according to guidelines, may be potentially reversible or may be accompanied by temporary contraindications to the implant. Moreover transvenous cardioverter defibrillator implantation still carries a not negligible risk of complications both acutely and at follow-up...

The number of children and adult with congenital heart disease requiring implantation of cardiac pacemaker or cardioverter defibrillator is constantly increasing. The lead between stimulation/defibrillation site and the generator constitutes the main weakpoint of those devices despite the numerous recent technological advances: use of bipolar probes, corticoid elution electrodes, insulation improvement, magnetic resonance imaging (MRI) compatibility. Risk of device failure remains high in this population. Long term adverse events with endovascular devices remain high...

There have been many evolutionary milestones in cardiac implantable electronic device (CIED) therapy over the past few decades. These advancements have created new  challenges. Right ventricular pacing was the original (late 1950s) breakthrough, however the risk of pacing induced dyssynchrony has become evident. Biventricular pacing provided a viable way to mitigate dyssynchrony, but only benefits certain patients (primarily left bundle branch block and QRS duration ≥150 ms with depressed left ventricular (LV) function)...

Aims: Single-chamber (VR-ICD) and subcutaneous (S-ICD) implantable cardioverter-defibrillators are effective to protect patients against sudden death but expose them to higher risk of inappropriate shock (IS). We sought to quantify the annual rate and influencing factors of ISs in VR- and S-ICDs from the literature. Methods and results: PubMed, Embase, and Cochrane Library were searched for full text articles with IS rates. Poisson distribution estimated proportion of patients with ISs; rates were annualized based on follow-up duration...
