Patients with diabetes mellitus, prior myocardial infarction, older age, and a relatively preserved left ventricular ejection fraction remain at risk for sudden cardiac death that is potentially amenable by the subcutaneous implantable cardioverter defibrillator with a good risk-benefit profile. The launched MADIT S-ICD study is designed to test the hypothesis that post-myocardial infarction diabetes patients with relatively preserved ejection fraction of 36%-50% will have a survival benefit from a subcutaneous implantable cardioverter defibrillator...

BACKGROUND: During early experience with subcutaneous implantable cardioverter defibrillator (S-ICD(TM)), several patients had inappropriate shocks from TWOS during exercise. This prompted some operators to perform routine treadmill exercise test after implantation of S-ICD to screen for TWOS. Meanwhile, improvements have been made in the detection algorithms by the manufacturer. OBJECTIVE: To assess whether routine treadmill exercise post S-ICD(TM) implantation is warranted...

BACKGROUND: Many patients with severe heart failure (HF) have an indication for baroreflex activation therapy (BAT) and an ICD. Concerns about device-device interactions were addressed in a study with small sample size that concluded combined BAT and ICD therapy is safe. There are no published data, however, concerning device-device interactions between BAT and a subcutaneous ICD (S-ICD). Since BAT frequently interferes with surface ECG recordings there are doubts about compatibility of BAT and S-ICD devices...

We present a case of a patient with a baroreceptor activation therapy (BAT) receiving a subcutaneous ICD. We anticipated two possible hazardous interactions between the two devices. Stimulation by the BAT could be adjudicated as noise and result in under-detection of ventricular arrhythmias or it might be misinterpreted as ventricular arrhythmias and lead to inappropriate shocks. Postop ensing occurred, the upper limit of pulse width of the BAT was limited because of noise detection by the S-ICD, but the upper limit of amplitude was limited by patient's discomfort...

PURPOSE: Subcutaneous implantable cardioverter defibrillator (S-ICD) is an alternative to transvenous ICD to prevent sudden cardiac death. Subcutaneous ICD implantation frequently requires general anesthesia because of procedure nociceptive steps during creation of a large device pocket and lead tunneling. This study aims to determine if a strategy of operator-guided controlled sedation with midazolam and analgesia with nalbuphine is effective in alleviating pain during S-ICD implantation...

Candidates for the subcutaneous implantable cardioverter-defibrillator (S-ICD) are screened using an electrocardiogram (S-ECG) tool to measure appropriate detection. We sought to define the S-ICD candidacy of congenital heart disease patients using the S-ECG tool. We also analyzed the reliability of the (S-ECG) tool between measurers in this population. Patients above the age of 12 and with a diagnosis associated with either a higher incidence of cardiac arrest or vascular access challenges were asked to undergo screening...

Screening tests conducted at rest may be inadequate for the prediction of the T-wave oversensing (TWOS) in subcutaneous implantable cardioverter defibrillator (S-ICD) candidates with Brugada syndrome (BrS) because of the dynamic nature of electrocardiogram (ECG) morphology. We evaluated the utility of ECG screening during drug challenge (DC) for prediction of TWOS in BrS patients implanted with an S-ICD. The study enrolled 6 consecutive BrS patients implanted with an S-ICD. In addition to baseline ECG screening, pre-implant screening during DC using a sodium channel blocker was performed in all patients...

BACKGROUND: The subcutaneous implantable cardioverter-defibrillator (S-ICD) was developed to reduce short- and long-term complications associated with transvenous ICD leads. Early multicenter studies included younger patients with less left ventricular systolic dysfunction and fewer comorbidities than cohorts with traditional ICD. OBJECTIVE: The purpose of this study was to characterize patient selection and the acute performance of the S-ICD in a contemporary real-world setting...

Aims: Totally subcutaneous implantable cardioverter defibrillator (S-ICD) delivers higher shock energy and can have longer time to therapy compared to transvenous implantable cardioverter defibrillator (T-ICD). Aim of the study was to compare time to therapy and to investigate cardiac, cerebral and systemic injuries of S-ICD and T-ICD shocks delivered after ventricular fibrillation (VF) induction. Methods and results: Fourteen pigs were randomly implanted with a S-ICD (n = 7) or a T-ICD (n = 7)...

A patient with Brugada Syndrome implanted with subcutaneous cardioverter defibrillator (S-ICD) had oversensing episodes treated with S-ICD shocks. Comparable artefacts weren't evocable with S-ICD pocket manipulation. The fluoroscopy excluded S-ICD macroscopic damage. The device extraction revealed undamaged pulse generator and connector, but the lead was inappropriately tunnelled under the sixth rib. Then the S-ICD malfunction was due to lead microscopic damage caused by lead rubbing the rib surface. This article is protected by copyright...

We report the case of a 51-year-old patient with Brugada syndrome (BrS) who experienced inappropriate shock due to T-wave oversensing (TWOS) during exercise when the optimal sensing vector was selected based on the automatic analysis by a subcutaneous implantable cardioverter-defibrillator (S-ICD). After selecting another vector during exercise testing, TWOS did not re-occur. Selection of appropriate sensing vector based on analyses under various conditions, including during exercise after S-ICD implantation, should be considered for patients with BrS...

BACKGROUND: The features of the hypertrophic cardiomyopathy (HCM) ECG make it a challenge for subcutaneous implantable cardioverter-defibrillator (S-ICD) screening. We aimed to investigate the causes of screening failure at rest and on exercise to inform optimal S-ICD ECG vector development. METHODS AND RESULTS: One hundred and thirty-one HCM patients (age, 50±16 years; 92 males and 39 females) with ≥1 HCM risk factor for sudden death underwent S-ICD ECG screening at rest and on exercise...

Aims: In 2012, the first totally Subcutaneous Implantable Cardioverter-Defibrillator (S-ICD) was approved by the Food and Drug Administration (FDA) in the United States. A possible benefit of this device is that it does not involve placing leads 'in' or 'on' the heart, potentially reducing complications. Methods amd results: Ninety-one S-ICD and 182 single chamber TV-ICD implants were performed between 10/22/2012 and 9/22/2015. During this period of time, 91 patients with S-ICD were matched to TV-ICD patients using single centre NCDR ICD Registry Data based on dialysis status, gender, and age...

The implantable cardioverter-defibrillator (ICD) has shown its superiority to anti-arrhythmic drugs in the prevention of sudden cardiac death. However, the conventional transvenous ICDs are still associated with substantial risks and comorbidities mainly related to the transvenous leads. The recent advent of an entirely sub-cutaneous ICD (S-ICD) represents an important progress in the defibrillation technology towards a less invasive approach. Clinical data are growing regarding the safety and efficacy of S-ICD in prevention of sudden cardiac death in selected patients without pacing indications...

BACKGROUND: Subcutaneous implantable cardioverter-defibrillators (S-ICD) could eliminate lead-associated complications. We assessed the prevalence of S-ICD ineligibility in conventional ICD recipients and compared it in patients with and without Brugada syndrome (BrS).Methods and Results:Consecutive patients with a transvenous ICD without an indication for antibradycardia pacing were assessed. A patient was considered eligible for S-ICD if the ECG satisfied the screening template, both supine and standing, in ≥1 lead...

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...

The subcutaneous implantable cardioverter-defibrillator (S-ICD) is a novel technology with proven efficacy in sudden cardiac death prevention; however, there is a lack of long-term safety data. We describe the case of a 55-year-old female patient implanted with an S-ICD due to idiopathic ventricular fibrillation, who subsequently presented with inappropriate shocks leading to ventricular fibrillation that was successfully terminated by another shock. Inappropriate shocks were due to intermittent T wave oversensing during periods of rate-dependent right bundle branch block...

INTRODUCTION: The subcutaneous implantable cardioverter defibrillator (ICD) has emerged as a viable therapeutic option for patients who are deemed high risk for sudden cardiac death. Previous studies have shown that 7-15% of patients are not candidates for the S-ICD based on their intrinsic QRS/T-wave morphology. Presently, it is not known if the S-ICD can be considered as supplementary therapy in patients who are ventricularly paced. We sought to determine the proportion of ventricularly paced patients who would qualify for an S-ICD...
