Optimal Medical Therapy for Heart Failure and Integrated Care in Patients With Atrial Fibrillation: A Report From the ESC-EHRA EORP Atrial Fibrillation Long-Term General Registry.

Background: Heart failure (HF) often occurs in patients with atrial fibrillation (AF), with a major impact on prognosis. Few data are available on the effect of integrated treatment strategies to improve prognosis in patients with AF. We aimed to evaluate the association between HF (according to left ventricular ejection fraction [LVEF]), HF optimal medical therapy and adherence to the Atrial Fibrillation Better Care pathway, and major outcomes in patients with AF.

Impact of Catheter Ablation on Atrial Fibrillation Burden and Symptoms in Patients With Hypertrophic Cardiomyopathy.

Background: Atrial fibrillation (AF) is more common in patients with hypertrophic cardiomyopathy (HCM) and is often highly symptomatic. The impact of catheter ablation (CA) may be under-reported when evaluated by long-term freedom from any atrial arrhythmia.

Objectives: This study aims to evaluate whether CA of AF in patients with HCM would significantly reduce AF burden and improve symptoms.

Aspirin and Ticagrelor Versus Aspirin and Clopidogrel or Prasugrel and the Effect on Staphylococcal-associated Infections: A Real-world Study.

Purpose: Antiplatelet therapy is used for the primary and secondary prevention of thrombotic diseases such as acute coronary syndrome (ACS). These patients are more vulnerable to infections, as such, strategies are required to mitigate these risks.

Methods: We conducted a retrospective cohort study using TriNetX, a global federated health research network that includes both inpatient and outpatient electronic medical records from health care organizations worldwide.

Predictors of the need for atrioventricular nodal ablation following redo ablation for atrial fibrillation.

Background: Patients who have recurrent atrial fibrillation (AF) following redo catheter ablation may eventually be managed with a pace-and-ablate approach, involving pacemaker implant followed by (AVNA). We sought to determine which factors would predict subsequent AVNA in patients undergoing redo AF ablation.

Methods: We analyzed patients undergoing redo AF ablations between 2013 and 2019 at our institution.

Cost, efficiency, and outcomes of pulsed field ablation vs thermal ablation for atrial fibrillation: A real-world study.

Background: With the exponential growth of catheter ablation for atrial fibrillation (AF), there is increasing interest in associated health care costs. Pulsed field ablation (PFA) using a single-shot pentaspline multielectrode catheter has been shown to be safe and effective for AF ablation, but its cost efficiency compared to conventional thermal ablation modalities (cryoballoon [CB] or radiofrequency [RF]) has not been evaluated.

Objective: The purpose of this study was to compare cost, efficiency, effectiveness, and safety between PFA, CB, and RF for AF ablation.

Randomised controlled trial of population screening for atrial fibrillation in people aged 70 years and over to reduce stroke: protocol for the SAFER trial.

Introduction: There is a lack of evidence that the benefits of screening for atrial fibrillation (AF) outweigh the harms. Following the completion of the Screening for Atrial Fibrillation with ECG to Reduce stroke (SAFER) pilot trial, the aim of the main SAFER trial is to establish whether population screening for AF reduces incidence of stroke risk.

Methods And Analysis: Approximately 82 000 people aged 70 years and over and not on oral anticoagulation are being recruited from general practices in England.

Durability of thermal pulmonary vein isolation in persistent atrial fibrillation assessed by mandated repeat invasive study.

Background: No study has assessed the durability of pulmonary vein isolation (PVI) with radiofrequency (RF) and cryoballoon (CB) in patients with persistent atrial fibrillation. These data are especially lacking for those with significantly diseased left atria (LA).

Objectives: The goals of this study were to assess PVI durability in patients with significant LA disease and to compare reconnection rates between RF and CB.

Cryoballoon pulmonary vein isolation as first-line treatment of typical atrial flutter: long-term outcomes of the CRAFT trial.

Background: CRAFT was an international, multicentre, randomised controlled trial across 11 sites in the United UK and Switzerland. Given the evidence that pulmonary vein triggers may be responsible for atrial flutter (AFL) as well as atrial fibrillation (AF), we hypothesised that cryoballoon pulmonary vein isolation (PVI) would provide greater symptomatic arrhythmia reduction than cavotricuspid isthmus (CTI) ablation, whilst also reducing the subsequent burden of AF. Twelve-month outcomes were previously reported.

Novel stroke prevention strategies following catheter ablation for atrial fibrillation.

Stroke prevention following successful catheter ablation of atrial fibrillation remains a controversial topic. Oral anticoagulation is associated with a significant reduction in stroke risk in the general atrial fibrillation population but may be associated with an increased risk of major bleeding, and the benefit: risk ratio must be considered. Improvement in successful catheter ablation and widespread use of cardiac monitoring devices may allow for novel anticoagulation strategies in a subset of patients with atrial fibrillation, which may optimize stroke prevention while minimizing bleeding risk.

Silent pulmonary veins at redo ablation for atrial fibrillation: Implications and approaches.

Background: Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation. Despite promising success rates, redo ablation is sometimes required. At redo, PVs may be found to be isolated (silent) or reconnected.

UltraSOUND-based characterization of ventricular tachycardia SCAR and arrhythmogenic substrate: The SOUNDSCAR study.

Background: Intracardiac echocardiography (ICE) represents a valuable image integration technique, with the unique advantage of dynamic real-time scar characterization.

Objectives: The goals of this study were to assess the correlation between ICE-defined and electroanatomic mapping (EAM)-defined scar in patients with ischemic cardiomyopathy and to define the outcomes of ICE-guided ventricular tachycardia (VT) ablation.

Methods: Thirty-eight patients with ischemic cardiomyopathy (SOUNDSCAR cohort) underwent full left ventricular (LV) ICE imaging and EAM.

Invasive Management of Hypertrophic Cardiomyopathy With Clinically Important Obstruction: Catheter Intervention Is Superior.

Hypertrophic cardiomyopathy is a common inherited cardiac condition where the myocardium progressively thickens in the absence of abnormal loading conditions. Left ventricular hypertrophy often leads to outflow tract obstruction, and this confers significant mortality and morbidity implications. Septal reduction therapies aim to relieve the obstruction in an attempt to reduce the burden of symptoms and potentially improve prognosis.

Interventions in Hypertrophic Obstructive Cardiomyopathy.

Obstructive hypertrophic cardiomyopathy is the most common genetically transmitted cardiomyopathy that is associated with significant morbidity and mortality. Despite contemporary treatments and interventions, the management of patients with obstructive hypertrophic cardiomyopathy remains poorly defined compared with other branches of cardiology. In this review, we discuss established and novel therapeutic interventions in patients with obstructive hypertrophic cardiomyopathy with a focus on percutaneous and surgical strategies including surgical myectomy, mitral valve repair or replacement, percutaneous alcohol septal ablation, pacemaker and cardioverter-defibrillator implantation, septal embolization, radiofrequency endocardial catheter ablation, and percutaneous intramyocardial septal radiofrequency ablation.

Validating the predictive ability of the 2MACE score for major adverse cardiovascular events in patients with atrial fibrillation: results from phase II/III of the GLORIA-AF registry.

The 2MACE score was specifically developed as a risk-stratification tool in atrial fibrillation (AF) to predict cardiovascular outcomes. We evaluated the predictive ability of the 2MACE score in the GLORIA-AF registry. All eligible patients from phase II/III of the prospective global GLORIA-AF registry were included.

Left Atrial Appendage Occlusion-A Choice or a Last Resort? How to Approach the Patient.

Left atrial appendage (LAA) occlusion is emerging as a viable alternative to oral anticoagulation in high-risk patients with atrial fibrillation. However, there remains limited evidence for this approach, especially in certain subgroups, and therefore patient selection is an important aspect of treatment. Here, the authors present arguments for LAA occlusion as either a last resort versus patient choice by evaluating contemporary studies on this topic and discuss practical steps in the approach of patients who may be suitable for LAA occlusion.

Simplified Geleijnse score for identifying chest pain features associated with coronary ischemia.

Background: The Geleijnse score, which was proposed to assess for coronary ischemia, has practical limitations.

Objectives: Our aim was to design and evaluate a simplified version of the Geleijnse score.

Methods: We enrolled patients with suspected coronary heart disease but negative troponin T or absence of enzymatic curve, and a non-diagnostic 12-lead ECG.

Adherence to the Atrial Fibrillation Better Care (ABC) pathway and the risk of major outcomes in patients with atrial fibrillation: A post-hoc analysis from the prospective GLORIA-AF Registry.

Background: The 'Atrial fibrillation Better Care' (ABC) pathway has been proposed to streamline a more holistic or integrated care approach to atrial fibrillation (AF) management. We aimed to analyse the impact of adherence to the ABC pathway on the risk of major adverse outcomes in a contemporary prospective global cohort of patients with AF.

Methods: Patients enrolled Phase II and III of the GLORIA-AF Registry with complete data on ABC pathway adherence and follow-up were included in this post-hoc analysis between November 2011 and December 2014 for Phase II, and between January 2014 and December 2016 for Phase III.

Contemporary management of atrial fibrillation and the predicted vs. absolute risk of ischaemic stroke despite treatment: a report from ESC-EHRA EORP-AF Long-Term General Registry.

Background: Risk stratification in patients with atrial fibrillation (AF) is important to facilitate guideline-directed therapies. The Calculator of Absolute Stroke Risk (CARS) scheme enables an individualized estimation of 1-year absolute risk of stroke in AF. We aimed to investigate the predicted and absolute risks of ischaemic stroke, and evaluate whether CARS (and CHA2DS2-VASc score) may be useful for identifying high risk patients with AF despite contemporary treatment.

Cryoballoon Pulmonary Vein Isolation as First-Line Treatment for Typical Atrial Flutter.

Objective: We aimed to compare cryoballoon pulmonary vein isolation (PVI) with standard radiofrequency cavotricuspid isthmus (CTI) ablation as first-line treatment for typical atrial flutter (AFL).

Methods: Cryoballoon Pulmonary Vein Isolation as First-Line Treatment for Typical Atrial Flutter was an international, multicentre, open with blinded assessment trial. Patients with CTI-dependent AFL and no documented atrial fibrillation (AF) were randomised to either cryoballoon PVI alone or radiofrequency CTI ablation.

Impact of ABC (Atrial Fibrillation Better Care) pathway adherence in high-risk subgroups with atrial fibrillation: A report from the ESC-EHRA EORP-AF long-term general registry.

Background: Effects of Atrial Fibrillation Better Care (ABC) adherence among high-risk atrial fibrillation (AF) subgroups remains unknown. We aimed to evaluate the impact of ABC adherence on clinical outcomes in these high-risk patients.

Methods: EORP-AF General Long-Term Registry is a prospective, observational registry from 250 centres across 27 European countries.

Social determinants of health and recurrence of atrial fibrillation after catheter ablation: a Danish nationwide cohort study.

Aims: To examine the associations between three social determinants of health (SDOH) and recurrence of AF after ablation.

Methods And Results: We selected patients who underwent a first ablation after an incident hospital diagnosis of AF between 2005 and 2018 from the entire Danish population. Educational attainment, family income, and whether the patient was living alone were assessed at the time of ablation.
