Summary: In a multicentre case series, it was found that a novel issue in S-ICD systems, Sense-B-noise, could lead to inappropriate shocks. This issue is characterized by signal saturation and diminished QRS amplitudes, despite normal X-ray and electrical measurements. Reprogramming the device to a secondary sensing vector has been shown to effectively resolve this problem.

Summary: The study found a significant decrease in appropriate and inappropriate ICD therapy and shocks over the past decade. While a large proportion of patients still experienced ICD therapy, significant differences were observed by cardiac diagnosis.

Summary: This systematic review analyzed the phenomenon of air entrapment (AE) as a potential cause of early inappropriate shocks (ISs) following subcutaneous implantable cardioverter defibrillator (S-ICD) implantation. The study included 54 patients with AE as a potential cause of S-ICD malfunction, with an overall incidence of 1.2%. Radiologic diagnosis of AE was confirmed in 28% of the entire study cohort. The management approach of non-invasive management, primarily device reprogramming, appeared to be effective in most patients.

Summary: Based on the updated evidence, subcutaneous implantable cardioverter-defibrillator (S-ICD) is safer and more effective than transvenous implantable cardioverter-defibrillator (TV-ICD) as it reduces the incidence of pocket complications, lead displacement or fracture, inappropriate sensing, defibrillation lead failure, pneumothorax/hemothorax, device failure, lead erosion, and all-cause mortality.

Summary: The aim of this study was to evaluate the impact of the SMART Pass (TM) algorithm on inappropriate therapy (IT) in subcutaneous internal cardiac defibrillator (S-ICD) and to explore the association between SP deactivation and IT. The results showed that SP deactivation was significantly associated with an increased risk of IT, and changing the sensing vector was successful in preventing IT.

Summary: This study aimed to investigate the pre-implant factors associated with inappropriate shocks for the latest generation of S-ICDs. The results showed that automatic pre-implant screening data are a useful predictor of inappropriate shocks. Along with other clinical factors, electrocardiogram features should be taken into consideration to identify patients at high risk of inappropriate shocks.

Summary: The study found apparent non-linear associations between night-time heart rate and ventricular tachyarrhythmias (VTAs) and ICD shocks. An increasing incidence of VTAs and ICD shocks was observed at both low and high levels of night-time heart rate, with a night-time heart rate of 50-70 bpm potentially being the optimal therapeutic target for the management of ICD/CRT-D recipients.

Summary: In this trial, there was no difference in shock efficacy between S-ICD and TV-ICD. Although patients in the S-ICD group were more likely to receive shocks, the total number of appropriate shocks did not differ between the two groups.

Summary: The combined implantation of cardiac contractility modulation (CCM) with subcutaneous implantable cardioverter-defibrillator (S-ICD) appears to be a suitable option for reducing the amount of intracardiac leads and complications for patients. It can be a good and safe choice for patients, improving heart failure symptoms when device interference is being ruled out.

Summary: This study found that a discordance of QRS to T-wave in lead I turned out to be a strong predictor for future inappropriate shocks in a typical S-ICD (R) cohort, with a special impact on patients with hypertrophic cardiomyopathy (HCM).

Summary: In patients with ischemic heart disease, the severity of coronary atherosclerotic lesions is associated with the occurrence of ventricular arrhythmias, with higher Syntax scores indicating more severe atherosclerosis and a greater burden of VA.

Summary: This study evaluated the clinical outcomes of subcutaneous implantable cardioverter-defibrillator (S-ICD) and single-chamber transvenous (TV-ICD) in an all-comers population and found no significant differences in the composite endpoint, including survival, freedom of hospitalization, and device-associated events, between the two.

Summary: This study assessed the incidence rate of appropriate device therapies in patients with secondary prevention ICD implants. The results showed that the risk of recurrent ventricular arrhythmia was highest in the first 3 months after device insertion and decreased over time. The cumulative incidence of arrhythmic syncope resulting in sudden cardiac incapacitation was highest within the first 90 days and subsequently dropped. Therefore, lowering the driving restrictions period to 3 months seems to be safe.

Summary: R-wave double counting is a rare cause of ventricular oversensing that can lead to inappropriate shocks. Optimizing device programming is essential for the avoidance of subsequent inappropriate therapies.

Summary: Implantable cardioverter defibrillators (ICDs) are effective in reducing the risk of sudden cardiac death, but transvenous implantation carries high risk. Subcutaneous ICDs (S-ICDs) offer a safer alternative for select patients.

Summary: This study aimed to evaluate the progression of comorbidities and their association with mortality after CRT-D generator replacement, and develop a risk score to identify patients at high risk for mortality post-replacement. The findings showed that an increase in comorbidities post-replacement was observed in some patients, and a simple risk score accurately predicted 5-year mortality. Patients with a risk score greater than 2.5 had higher mortality rates compared to those with a lower risk score.

Summary: This study in a Dutch cohort of implantable cardioverter-defibrillator patients found that 13.6% experienced complications, with 7.8% being major complications. Lead-related issues and infections were the most common. Stricter implant indication criteria could potentially reduce complications.

Summary: Management of heart failure remains challenging despite advances in medical and pharmacological treatments. Strategies to reduce hospitalizations and readmission rates are urgently needed. Remote monitoring of high-risk patients, including those with cardiac implantable electronic devices, has shown promise in clinical practice for early identification of worsening heart failure.

Summary: This study compared healthcare utilization up to 3 year follow-up in implantable cardioverter-defibrillator (ICD) patients with remote care compared to conventional care. The results showed that remote care was associated with a sustained lower rate of planned and unplanned healthcare utilization up to 3 subsequent years after ICD/CRT-D implantation, with no significant difference in one-year all-cause mortality.

Summary: The study found that a heart rate score (HrSc) greater than or equal to 70% is related to chronotropic incompetence and clinical sick sinus syndrome in pacemaker subjects. This measurement can serve as a quantitative indicator of chronotropic incompetence in pacemaker subjects.
