BACKGROUND: Effective treatment of paroxysmal atrial fibrillation (AF) is essential for reducing the risk of stroke and heart failure. Cryoballoon (CB) ablation has been developed as an alternative to the use of radiofrequency (RF) energy for electrical isolation of the pulmonary veins. Herein, we provide long-term data regarding the efficacy of CB ablation in comparison to RF. METHODS: FreezeAF was a randomised non-inferiority study comparing CB ablation with RF ablation for the treatment of patients with drug-refractory paroxysmal AF...

Aims: A commonly held notion is that patients with a family history of atrial fibrillation (AF) have worse atrial substrate and higher rates of arrhythmia recurrence following ablation. We sought to examine differences in atrial substrate and catheter ablation outcomes in patients with a 1st degree family member with paroxysmal or persistent AF (PeAF) compared to those without. Methods and results: A total of 256 consecutive patients undergoing their 1st ablation for AF (123 paroxysmal, 133 persistent) with >1 year follow up were included...

OBJECTIVE: Although Type D personality has been associated with the prognosis of various cardiac diseases, few studies have investigated the influence of Type D personality on the cardiac and psychiatric prognoses of patients with atrial fibrillation (AF). METHODS: Depression, anxiety, and quality of life were measured at baseline and 6 months. The recurrence of AF was measured during 1-year following radiofrequency catheter ablation (RFCA) for AF. The Kaplan-Meier method with log-rank tests were used to compare the cumulative recurrence of AF...

OBJECTIVE: Although the benefit of surgical ablation for atrial fibrillation (AF) performed concomitant to mitral valve surgery is established, whether that performed concomitant to non-mitral cardiac surgery is beneficial remains unclear. In non-mitral, non-left-atriotomy cardiac surgery, the optimal surgical approach for AF remains to be established. Therefore, using the Japan Adult Cardiovascular Surgery Database (JACVSD), we compared 2 surgical ablation procedures [the maze procedure and pulmonary vein isolation (PVI)] performed concomitant to non-mitral cardiac surgery...

The purpose of the present study was to compare the efficacy and safety of dabigatran and interrupted warfarin with low-molecular-weight heparin bridging in non-valvular atrial fibrillation (AF) catheter ablation. Previously, there has been concerns that bridging therapy increases bleeding events without the benefit of stroke prevention. It has been suggested that bridging therapy should be considered only for patients at high-risk of thrombosis. Nevertheless, bridging therapy in AF patients with a low CHADS2 score may be safe and effective...

BACKGROUND: Given the potential complications of atrial fibrillation (AF) recurrence after ablation, better predictors of the effectiveness of the procedure are necessary to guide patient selection. AIM: This prospective study was conducted to evaluate the clinical relevance of global left atrial longitudinal strain (GLAS) and AF recurrence after catheter ablation. METHODS: In 115 consecutive patients with AF (persistent, n=62; paroxysmal, n=53), transthoracic echocardiography was performed before catheter ablation to assess baseline left atrial mechanical function using speckle tracking echocardiography (STE)...

Aims: Galectin-3 (Gal-3) is an important mediator of cardiac fibrosis, particularly in heart failure. Increased Gal-3 concentration (Gal-3), associated with increased risk of developing atrial fibrillation (AF), may reflect atrial fibrotic remodelling underlying AF progression. We aimed to investigate whether the change in serum Gal-3 reflects alterations of the arrhythmogenic atrial substrate following thoracoscopic AF surgery, and predicts absence of AF. Methods and results: Consecutive patients undergoing thoracoscopic AF surgery were included...

BACKGROUND: Following ablation therapy for cardiac arrhythmias, patients may develop upper gastrointestinal (UGI) symptoms. The vagus nerve is close to the atria and may be affected by ablating energy. AIM: To identify structural or functional complications in UGI tract following ablation for atrial fibrillation (AF) and clinical outcomes and association with vagal dysfunction. METHODS: Using natural language processing of electronic medical records and an AF ablation database of 5380 patients treated during 17 years, we identified 40 patients with UGI complications...

Catheter-based ablation is an established treatment option for patients with symptomatic atrial fibrillation (AF). Pulmonary vein isolation is the established cornerstone of all ablation strategies. However, the rate of electrical reconduction of previously isolated pulmonary veins is high and associated with recurrence of AF. Novel and innovative mapping and ablation systems are being developed or are under clinical evaluation aiming for higher durability of pulmonary vein isolation. Additional ablation strategies for patients with recurrence of AF despite persistent isolation of the pulmonary veins are under evaluation...

Long-term cessation of oral anticoagulation (OAC) following successful catheter or surgical ablation of atrial fibrillation (AF) is debated. Usually, in the presence of sinus rhythm at serial ECG recordings, the CHADS2, CHA2DS2VASc, and HAS-BLED scores are adopted to guide decision regarding OAC management. Areas covered: The safety of OAC cessation in patients without recurrent AF but with historically elevated risk for thromboembolism remains largely unknown. Taking the cue from two clinical cases, we provide an updated summary of the latest evidence regarding how to manage OAC after a successful atrial fibrillation ablation...

Pulmonary veins isolation (PVI) by radiofrequency (RF) ablation is currently an established treatment for symptomatic, drug-resistant paroxysmal atrial fibrillation. Although the effectiveness of the therapy has been clearly demonstrated, success rate after a single procedure is still sub-optimal. The main reason for recurrences after PVI is electrical pulmonary vein-atrium reconnection. In order to increase the likelihood of permanent PVI, the creation of a transmural, durable lesion is mandatory. The main determinants of lesion size and transmurality are power, stability, duration and contact-force during RF application...

BACKGROUND: We reviewed trends from 2004 to 2013 in the incidence and outcomes for atrial fibrillation (AF) in Spanish patients with type 2 diabetes mellitus (T2DM) comparing women and men. METHODS: We used national hospital discharge data including all T2DM patients discharged from the hospital after AF. Patients with AF in the primary diagnosis field were selected. Discharges were grouped by sex. Incidence was calculated overall and stratified by sex. We analyzed diagnostic and therapeutic procedures, patient comorbidities, CHA2DS2-VASc score, length of hospital stay, readmission rates and in-hospital mortality (IHM)...

BACKGROUND: Supraventricular ectopic complexes (SVEC) originating in the pulmonary veins are known triggers of atrial fibrillation (AF) which led to the development of pulmonary vein isolation for AF. However, the long-term prevalence of SVEC after catheter ablation (CA) as compared to antiarrhythmic medication (AAD) is unknown. Our aims were to compare the prevalence of SVEC after AAD and CA and to estimate the association between baseline SVEC burden and AF burden during 24months of follow-up...

Use of the antiarrhythmic ibutilide after isolated pulmonary vein isolation (PVI) might distinguish atrial remodeling severity and cases requiring further substrate modification, thereby improving efficacy of persistent atrial fibrillation (AF) treatment. Ninety-six consecutive patients with persistent AF were randomized after PVI to either direct current synchronized cardioversion (DCC group, n = 48) or 1 mg of intravenous ibutilide (ibutilide group, n = 48) followed by no further intervention if AF converted to sinus rhythm (SR) within 30 minutes (ibutilide conversion subgroup) or by complex fractionated atrial electrogram (CFAE) ablation until SR recovery or complete CFAE elimination (ibutilide nonconversion subgroup)...

Despite the very promising initial results of clinical studies, catheter ablation of persistent atrial fibrillation (AF) remains a challenge in modern electrophysiology. On the basis of the hypothesized pathophysiological mechanisms, a variety of ablation strategies have been developed over the course of time. The current ablation strategies range from pulmonary vein isolation (PVI) alone as first-line therapy, through ablation of multiple linear lesions, ablation of complex fractionated atrial electrograms (CFAE), rotor ablation, isolation of fibrotic and scar tissue up to isolation of the left atrial appendage (LAA); however, it is unclear even to the present day whether these complex and time-consuming strategies actually improve the success rate of ablation therapy...

BACKGROUND: Previous reports on patients with radiofrequency catheter ablation (RFCA) of accessory pathway (AP) and atrial fibrillation (AF) include only short follow-up periods. The aim of this study was to analyse predictors of recurrence of AF in patients after successful RFCA of APs over long term follow-up periods. METHODS: Of the 1,007 patients who underwent non-pharmacological treatment of Aps ( between the years 1993-2008), data of 100 consecutive patients were retrospectively analyzed (75 men, mean age 43...

Atrial fibrillation (AF) is leading cardiac arrhythmia with important clinical implications. Its diagnosis is usually made on the basis on 12-lead ECG or 24-hour Holter monitoring. More and more clinical evidence supports diagnostic use of cardiac event recorders and cardiovascular implantable electronic devices (CIED). Treatment options in patients with atrial fibrillation are extensive and are based on chosen rhythm and/or rate control strategy. The use and selected contraindications to AF related pharmacotherapy, including anticoagulants are shown...

Introduction: We aimed to study the procedural characteristics, efficacy and safety of cryoballoon ablation (CBA) versus radiofrequency ablation (RFA) for catheter ablation of paroxysmal atrial fibrillation (AF). Methods: A systematic literature search was performed using PubMed, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials to clinical trials comparing CBA and RFA for AF. Outcomes were evaluated for efficacy, procedure characteristics and safety. For each study, odd ratio (OR) and 95% confidence intervals (CIs) were calculated for endpoints for both approaches...

OBJECTIVE: Although the Cox-maze operation is the standard surgical procedure for permanent atrial fibrillation(AF), conversion to sinus rhythm is limited by patient characteristics, including the duration of AF, atrial size, and voltage of fibrillation waves. A surgical strategy based on structural alteration of the electrical substrates of AF is required to achieve better outcomes of AF surgery. Complex fractionated atrial electrogram (CFAE) plays an important role in the electrical substrate of AF...

BACKGROUND: Long-term recurrence (LR) is a tendency that re-occurs within 3 months after catheter ablation for atrial fibrillation (AF). Whether very early recurrence (VER) within 7 days of post ablation is a prognostic factor of LR or not is unclear. For this reason, present study sought to examine the relationship between VER and LR. METHODS: In this prospective analysis 378 consecutive patients underwent an initial catheter ablation for paroxysmal or persistent AF...
