Inappropriate Therapy and Shock Rates Between the Subcutaneous and Transvenous Implantable Cardiac Defibrillator: A Secondary Analysis of the PRAETORIAN Trial.
Circ Arrhythm Electrophysiol
December 2024
Article Synopsis
- Inappropriate therapy (IAT) is a significant issue associated with implantable cardiac defibrillator (ICD) therapy, particularly highlighted in early subcutaneous ICD (S-ICD) studies which showed high rates of inappropriate shocks (IAS).
- The PRAETORIAN trial, an international study with 849 patients, found no major differences in IAT and IAS rates between S-ICD and transvenous ICD (TV-ICD) groups, as both groups had similar cumulative incidences.
- Key predictors for IAT varied between the two groups, with TV-ICD patients experiencing IAT mainly from supraventricular tachycardias, while S-ICD patients faced issues from cardiac oversensing
Article Synopsis
- The S-ICD was created to eliminate lead-related issues found in the TV-ICD, as it is an external device that sits under the skin rather than using leads inside the body.
- This analysis comes from the PRAETORIAN trial, where patients were randomly assigned to either S-ICD or TV-ICD and assessed for quality of life through various questionnaires at different stages.
- Results showed no significant differences in physical and mental well-being between the groups, but patients who experienced a shock recently reported lower social functioning and emotional health compared to those who did not.
Background: The patterns of direct oral anticoagulant (DOAC) selection and switching to a different oral anticoagulant (OAC) in patients with atrial fibrillation (AF) are unknown.
Objectives: To describe temporal patterns in first DOAC prescriptions, estimate the incidence, and identify predictors of switching to a different OAC within 1 year in OAC-naive AF patients.
Methods: In this retrospective cohort study, using a near-nationwide prescription registry (IQVIA, the Netherlands), we determined the number of patients per month initiated on each DOAC and identified predictors of switching within 1 year with robust Poisson regression.
Background: Obesity increases the risk of atrial fibrillation (AF). We hypothesize that 'obese' epicardial adipose tissue (EAT) is, regardless of comorbidities, associated with markers of AF vulnerability.
Methods: Patients >40y of age undergoing bariatric surgery and using <2 antihypertensive drugs and no insulin were prospectively included.
Background: Short and rare episodes of atrial fibrillation (AF) are commonly detected using implanted devices (device-detected AF) in patients with prior stroke or transient ischemic attack (TIA). The effectiveness and safety of oral anticoagulation in patients with prior stroke or TIA and device-detected AF but with no ECG-documented AF is unclear.
Methods And Results: This prespecified analysis of the NOAH-AFNET 6 (Non-Vitamin K Antagonist Oral Anticoagulants in Patients With Atrial High Rate Episodes) trial with post hoc elements assessed the effect of oral anticoagulation in patients with device-detected AF with and without a prior stroke or TIA in the randomized, double-blind, double-dummy NOAH-AFNET 6 trial.
Introduction: Both the prevalence of atrial fibrillation (AF) and its subsequent use of direct oral anticoagulants (DOACs) are rapidly increasing in patients of older age. In the absence of contra-indications, guidelines advocate anticoagulation based on the CHA2DS2-VASc score for all AF patients aged 75 and above. However, some practitioners are hesitant to prescribe anticoagulants to older and frail patients due to perceived elevated bleeding risks.

Since then, publications using the term were sporadic until the decision was made to convene an expert working group with representation from four multinational arrhythmia organizations to prepare a consensus document on atrial cardiomyopathy in 2016 (EHRA/HRS/APHRS/SOLAECE expert consensus on atrial cardiomyopathies: definition, characterization, and clinical implication). Subsequently, publications on AtCM have increased progressively.

Objectives: To determine the incidence of WRF in patients with AF treated with edoxaban, the association of WRF with clinical outcomes, and predictors of WRF and clinical outcomes in these patients.
Methods: This is a subanalysis of the Edoxaban Treatment in routiNe clinical prActice for patients with non-valvular Atrial Fibrillation in Europe study (NCT02944019), an observational study of edoxaban-treated patients with AF.
Article Synopsis
- - Atrial fibrosis is a key factor in the development and persistence of atrial fibrillation (AF), but treating it is difficult due to the complex activity of atrial fibroblasts.
- - The study discovered that primary cilia play a crucial role in regulating the fibrotic response of atrial fibroblasts in AF, showing fewer ciliated fibroblasts in AF patients compared to those without AF.
- - Restoring or elongating primary cilia can potentially prevent the expression of fibrosis-related genes in AF patients, presenting a promising therapeutic strategy for managing atrial fibrosis.
Background: To assess long-term effectiveness and safety of edoxaban in Europe.
Methods And Results: ETNA-AF-Europe, a prospective, multinational, multi-centre, post-authorisation, observational study was conducted in agreement with the European Medicines Agency. The primary and secondary objectives assessed real-world safety (including bleeding and deaths) and effectiveness (including stroke, systemic embolic events and clinical edoxaban use), respectively.
Background: Screening of high-risk patients is advocated to achieve early detection and treatment of clinical atrial fibrillation (AF). The Dutch-GERAF study will address two major issues. Firstly, the effectiveness and feasibility of an opportunistic screening strategy for clinical AF will be assessed in frail older patients and, secondly, observational data will be gathered regarding the efficacy and safety of oral anticoagulation (OAC).

In this study, we assessed current preventive strategies used by Dutch cardiothoracic centres, identified common views on this matter and related these to international guidelines.
Methods: We developed an online questionnaire and sent it to all cardiothoracic surgery centres in the Netherlands.
Background: Patients with excess epicardial adipose tissue (EAT) are at increased risk of developing cardiac arrhythmias. EAT promotes arrhythmias by depolarizing the resting membrane of cardiomyocytes, which slows down conduction and facilitates re-entrant arrhythmias. We hypothesized that EAT slows conduction by secreting extracellular vesicles (EVs) and their microRNA (miRNA) cargo.
View Article and Find Full Text PDFAims: We aimed to identify all syncope units (SUs) in the Netherlands and assess the extent to which these SUs fulfil the essential requirements outlined by the consensus statements of the European Heart Rhythm Association and the European Society of Cardiology syncope guidelines. For this, we developed the SU-19 score, a novel guideline based validation tool for best practice.
Methods And Results: All outpatient clinics of cardiology, neurology, and internal medicine in the Netherlands were screened for presence of any form of structured specialized syncope care.
Interpretation of field and LEAP potentials recorded from cardiomyocyte monolayers.
Am J Physiol Heart Circ Physiol
March 2024
Multielectrode arrays (MEAs) are the method of choice for electrophysiological characterization of cardiomyocyte monolayers. The field potentials recorded using an MEA are like extracellular electrograms recorded from the myocardium using conventional electrodes. Nevertheless, different criteria are used to interpret field potentials and extracellular electrograms, which hamper correct interpretation and translation to the patient.

Setting: Data from a historical cohort study in eight hospitals (both academic and non-academic) in the Netherlands between January 2020 and July 2021 were used in this study.
Participants: 3064 hospitalised COVID-19 patients >18 years old.
Background: Particularly in frail patients, anticoagulation may be underused because of the fear of bleeding.
Objective: To determine whether the use of antithrombotic medication is an independent risk factor for mortality in frail elderly with repeated falls.
Methods: All patients aged 65 years or older at the Fall and Syncope Clinic were eligible.
