Summary: This study investigates the impact of sleep-disordered breathing (SDB) treatment on ventricular tachycardia (VT) burden in heart failure (HF) patients. The results show that SDB treatment leads to significant improvements in VT burden, antitachycardia pacing (ATP), and shock therapy in HF patients with implantable cardioverter-defibrillator (ICD). SDB treatment may also affect the survival of HF patients.

Summary: This study describes the complications associated with implantable cardioverter-defibrillators (ICD) treatment in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). The results show that during long-term follow-up, approximately 41% of patients experienced potentially life-saving ICD therapy, while 27% had complications requiring surgery, mainly lead-related complications.

Summary: The benefit of implantable cardioverter-defibrillators (ICD) in non-ischemic systolic heart failure (NICM) patients is uncertain. This study aimed to investigate the incidence, predictors, and prognostic impact of ventricular arrhythmias in NICM patients with ICD. The results showed that ventricular arrhythmias occurred in approximately one-fourth of NICM and ICD patients, and were associated with worse prognosis compared to those without sustained ventricular arrhythmias.

Summary: Cardiac amyloidosis is a disease caused by deposition of misfolded AL or ATTR amyloid fibrils in the myocardium, resulting in restrictive cardiomyopathy and potential death. Ventricular arrhythmias are common, especially in AL, and can be due to several mechanisms including inflammatory cascade activation and systemic amyloid deposition. There is an increased risk of sudden cardiac death in cardiac amyloidosis, particularly in AL. The use of implantable cardioverter-defibrillators in cardiac amyloidosis remains controversial, as there is limited evidence for their effectiveness in primary prevention.(c) 2023 Japanese College of Cardiology.

Summary: This study investigated the impact of changes in patient care during the COVID-19 pandemic on the arrhythmic and clinical condition of patients with an implantable cardioverter defibrillator (ICD). The findings showed that the reduction of in-person visits did not result in a deterioration of the patients' arrhythmic and clinical condition.

Summary: This study showed that myocardial scar characterization based on cardiac magnetic resonance imaging can improve risk stratification for ventricular arrhythmia occurrence in patients with ischemic cardiomyopathy who received an Implantable Cardioverter-Defibrillator (ICD). The analysis revealed that total scar mass and border zone mass independently predicted appropriate ICD therapy, suggesting the importance of myocardial scar assessment in determining the risk of ventricular arrhythmias in this patient population.

Summary: Sleep-disordered breathing (SDB) has significant cardiovascular and neurological effects, with supplemental oxygen therapy showing mixed results in improving oxygen saturation and apnea severity compared to positive airway pressure therapy. Further research is needed to clarify the optimal dose and duration of nocturnal supplemental oxygen (NSO) and its combination with PAP in improving cardiovascular, sleep, and cognitive outcomes in SDB patients.

Summary: This study analyzed the outcomes of subcutaneous implantable cardioverter-defibrillators (S-ICDs) in patients with congenital heart disease (CHD). Among 4,924 patients who received an S-ICD implant, 101 had CHD. The study found that S-ICDs are effective and safe in patients with CHD.

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: This study systematically reviewed the effectiveness and safety of oral mexiletine in adult patients with structural heart disease and implantable cardioverter defibrillators for recurrent ventricular arrhythmia. The results showed that mexiletine reduced the number of ICD therapies, especially in patients where catheter ablation was not successful or contraindicated. However, in patients with ischemic cardiomyopathy, mexiletine seemed to be less effective than catheter ablation. The main side effects of mexiletine were related to gastrointestinal and neurological systems.

Summary: This study aimed to compare outcomes of epicardial versus transvenous implantable cardioverter defibrillators (ICDs) in children. The results showed that epicardial ICDs had more early and late complications compared to transvenous ICDs, but the association between ICD lead dysfunction and reintervention was no longer significant after controlling for confounding factors such as age and weight. Additionally, pleural coils were associated with better outcomes than epicardial coils in this population.

Summary: Large-scale studies on modern populations with implantable cardioverter-defibrillators (ICDs) are lacking. The UMBRELLA study analyzed the incidence of arrhythmia, device interventions, and mortality in a diverse group of real-world ICD patients with different heart disorders. Results showed that patients with certain heart conditions had higher risks of appropriate ICD therapies, while patients with other conditions had lower risks. Regardless of the cause, contemporary ICD patients with heart failure-related disorders had a similar risk of ICD life-saving interventions and death.

Summary: HFrecEF is recognized as a distinct clinical entity with increasing prevalence, and continued guideline-directed medical therapy is crucial to promote myocardial recovery. Despite the lower risk of sudden cardiac death in HFrecEF compared to HFrEF, the benefits of continued ICD therapy need to be weighed against potential risks and limitations.

Summary: This study aimed to evaluate the predictive value of the GRACE risk score in acute pulmonary embolism (PE) patients for 30-day mortality and the need for thrombolytic treatment. The study found that the GRACE risk score, along with the PESI score, were independent risk factors associated with 30-day mortality and the need for thrombolytic treatment. The GRACE risk score showed high sensitivity and specificity in predicting mortality, and its combination with the PESI score helped define high-risk PE patients and predict poor prognosis.

Summary: Transthoracic echocardiography (TTE) is commonly used to evaluate isolated tricuspid regurgitation (TR), but there is limited research comparing its quantification with magnetic resonance imaging (MRI). In this study, a novel TTE algorithm was developed to identify severe TR based on TTE parameters. The algorithm had a higher accuracy than the current guidelines' criteria in detecting severe TR by MRI.

Summary: This article presents a case of a patient with known situs inversus who underwent cardiac catheterization and was found to have chronic total occlusion in the right coronary artery. Situs inversus is a rare congenital abnormality characterized by the inverted position of chest and abdominal organs. Cardiac catheterization is uncommon in patients with this particular abnormality, highlighting the importance of customizing techniques to engage coronary arteries and optimize guide support for percutaneous coronary intervention if needed.

Summary: This study evaluated the angiogenic capacity of adipose tissue in patients undergoing cardiac surgeries and found that patients with coronary artery disease (CAD) had reduced angiogenic capacity in their pericardial adipose tissue. Gene expression analysis revealed upregulated expression of the anti-angiogenic gene TSP-1 in CAD patients, with no significant differences in other angiogenic factors. Additionally, inhibiting TSP-1 expression significantly improved angiogenic deficiency in CAD patients.

Summary: The current guidelines recommend prophylactic implantable cardioverter-defibrillator (ICD) for patients with symptomatic heart failure (HF) and low left ventricular ejection fraction. However, not all patients will benefit from ICD treatment. This study evaluated the feasibility of using the MADIT-II-based Risk Stratification Score (MRSS) to predict the survival benefit of prophylactic ICDs in patients with HF. The results showed that different risk subgroups had varying levels of ICD survival benefit.
