Atrial fibrillation is the most prevalent cardiac arrhythmia, affecting 10% of those aged over 80 years. Despite multiple treatment options, it remains an independent prognostic marker of mortality due to its association with clinical sequelae, particularly cerebrovascular events. Management can be broadly divided into treatment of the arrhythmia, via rhythm or rate control, and stroke thromboprophylaxis via anticoagulation. Traditional options for pharmacotherapy include negatively chronotropic drugs such as β-blockers, and/or arrhythmia-modifying drugs such as amiodarone...

OBJECTIVE: Atrial fibrillation (AF) is the most common sustained arrhythmia and is associated with increased morbidity and mortality. Atrial fibrosis augments recurrence rate following AF catheter ablation. Osteopontin is a multifunctional molecule involved in several pathophysiological pathways, including fibrosis. Presently described is investigation of relationship between serum osteopontin level and AF recurrence after AF cryoablation. METHODS: The study was designed to be prospective and observational; 60 patients with paroxysmal (n=47) and persistent (n=13) AF were included...

INTRODUCTION: The ligament of Marshall may hinder the creation of mitral isthmus (MI) block or pulmonary vein (PV) isolation (PVI) in radiofrequency (RF) catheter ablation of atrial fibrillation (AF). We aimed to assess the benefit of RF ablation targeting the vein of Marshall (VOM) in failed cases of MI block or PVI. METHODS AND RESULTS: We reviewed the medical records of patients who underwent RF ablation targeting the VOM after failed MI ablation or left PVI using the conventional method, which included circumferential point-by-point ablation around the PV antrum and carina, or endocardial MI and epicardial distal coronary sinus (CS) ablation for MI block...

AIMS: Early identification of patients who could benefit from early re-intervention after catheter ablation is highly warranted. Our aim was to investigate the association between post-procedural burden of supraventricular ectopic complexes (SVEC) and the risk of long-term atrial fibrillation (AF) recurrence. METHODS AND RESULTS: A total of 125 patients undergoing catheter ablation for AF were included. Patients underwent 7-day Holter recordings immediately post-procedural...

BACKGROUND: Warfarin is a well-established agent for use in the prevention of stroke or systemic embolic event (SEE) in patients with nonvalvular atrial fibrillation (NVAF) and for the treatment of venous thromboembolism (VTE). However, management of patients requiring oral anticoagulation with warfarin can be complicated by the need for frequent monitoring, drug-drug and drug-food interactions, and a variable response based on genetic polymorphisms. The non-vitamin K antagonist oral anticoagulants (NOACs) were developed as alternatives to warfarin; they do not require routine monitoring and have predictable pharmacokinetics, fewer drug-drug interactions, and limited drug-food interactions...

Left atrial (LA) volume (LAV) is used for the selection of patients with atrial fibrillation (AF) to rhythm control strategies. Calculation of LAV from the LA diameters and areas by two-dimensional (2D) echocardiography may result in significant error. Accuracy of atrial volume assessment has never been studied in patients with long-standing persistent AF (LSPAF) and significant atrial remodeling. This study investigated correlation and agreement between 2D echocardiographic (Simpson method) and electroanatomic (CARTO, Biosense Webster) left and right atrial (RA) volumes (LAV(ECHO) vs...

BACKGROUND: The optimal rhythm management strategy for people with non-paroxysmal (persistent or long-standing persistent) atrial fibrilation is currently not well defined. Antiarrhythmic drugs have been the mainstay of therapy. But recently, in people who have not responded to antiarrhythmic drugs, the use of ablation (catheter and surgical) has emerged as an alternative to maintain sinus rhythm to avoid long-term atrial fibrillation complications. However, evidence from randomised trials about the efficacy and safety of ablation in non-paroxysmal atrial fibrillation is limited...

BACKGROUND: Genome-wide association studies (GWAS) have identified several loci associated with atrial fibrillation (AF) and have been reportedly associated with response to catheter ablation for AF in patients of European ancestry; however, associations between susceptibility loci and clinical recurrence of AF after catheter ablation have not been examined in Chinese Han populations. To the personalization of catheter ablation for AF, we examined whether these single nucleotide polymorphisms (SNPs) can predict clinical outcomes after catheter ablation for AF in Chinese Han population...

Florian Hintringer
BACKGROUND: Atrial fibrillation (AF) affects 1-2% of the population, and its prevalence is estimated to at least double in the next 50 years as the population ages. AREAS OF AGREEMENT: AF results in impaired quality of life and even increased mortality. Drugs frequently fail to stabilize sinus rhythm. AREAS OF CONTROVERSY: Catheter ablation is a valuable treatment alternative, even as a first-line therapy in selected cases. However, catheter ablation of AF is challenging, even for experienced operators...

AIMS: Identifying patients who benefit from restored sinus rhythm (SR) would optimize the selection of candidates for ablation of long-standing persistent atrial fibrillation (LSPAF). This prospective study sought to identify the hitherto unknown factors associated with global functional improvement after successful radiofrequency catheter ablation of LSPAF. METHODS AND RESULTS: In 171 LSPAF patients (84% of the total consecutive 203 patients) who were examined in SR 12 months after ablation, the individual per cent change from baseline value in maximum oxygen consumption at exercise test (VO2 max), left ventricular ejection fraction (LVEF), N-terminal prohormone of brain natriuretic peptide (NT-proBNP), and five-dimensional descriptive system (EQ-5D) of quality-of-life questionnaire were classified in quartiles by 0 (worse) to 3 (best) grades...

AIMS: Pulmonary vein (PV) isolation (PVI) utilizing a cryoballoon (CB) has become one of the standard therapeutic options for atrial fibrillation (AF). However, it connotes a potential risk of cerebral ischaemic events (CIEs). This study aimed to clarify the prevalence of CIEs after PVI using second-generation CBs assessed by magnetic resonance imaging (MRI) of the brain. METHODS: This prospective observational study consisted of 160 patients that underwent PVI with second-generation CBs for drug-refractory AF...

INTRODUCTION: Although catheter ablation (CA) for atrial fibrillation (AF) is commonly used to improve symptoms, AF recurrence is common and new tools are needed to better inform patient selection for CA. Left atrial function index (LAFI), an echocardiographic measure of atrial mechanical function, has shown promise as a noninvasive predictor of AF. We hypothesized that LAFI would relate to AF recurrence after CA. METHODS AND RESULTS: All AF patients undergoing index CA were enrolled in a prospective institutional AF Treatment Registry between 2011 and 2014...

Many patients with atrial fibrillation have substantial symptoms despite ventricular rate control and require restoration of sinus rhythm to improve their quality of life. Acute restoration (ie, cardioversion) and maintenance of sinus rhythm in patients with atrial fibrillation are referred to as rhythm control. The decision to pursue rhythm control is based on symptoms, the type of atrial fibrillation (paroxysmal, persistent, or long-standing persistent), patient comorbidities, general health status, and anticoagulation status...

Control of the heart rate (rate control) is central to atrial fibrillation management, even for patients who ultimately require control of the rhythm. We review heart rate control in patients with atrial fibrillation, including the rationale for the intervention, patient selection, and the treatments available. The choice of rate control depends on the symptoms and clinical characteristics of the patient, but for all patients with atrial fibrillation, rate control is part of the management. Choice of drugs is patient-dependent...

INTRODUCTION: Over the last decade, tremendous progress has been made in defining the genetic architecture of atrial fibrillation (AF). This has in part been driven by poor understanding of the pathophysiology of AF, limitations of current therapies and failure to target therapies to the underlying mechanisms. AREAS COVERED: Genetic approaches to AF have identified mutations encoding cardiac ion channels, and signaling proteins linked with AF and genome-wide association studies have uncovered common genetic variants modulating AF risk...
