The midterm efficacy of hybrid ablation of atrial fibrillation (AF) reported in recent papers is about 70% in terms of sinus rhythm maintenance without antiarrhythmic drugs. Bearing in mind that the majority of patients enrolled are patients with persistent and long-standing persistent AF, the reported efficacies seem to be very good. Despite the high efficacies, safety remains a critical issue in hybrid, and especially thoracoscopic ablations. The frequency of complications during thoracoscopic ablations is more than 10% in the majority of reports...

Over the recent years, the advent of single-shot techniques, such as circular catheter and cryoballoon ablation, has ushered in a new era in the catheter ablation approach and rhythm control strategies of patients with atrial fibrillation (AF). These techniques make it easier to navigate the heart and have the potential to decrease the threshold for, expand the access to, and increase patient and physician acceptance of rhythm-control therapies, that may lead to reduction of the AF disease burden and its socioeconomic impact...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality worldwide. Identifying potentially-modifiable predictors of mortality could help optimize COPD patient management. The aim of this study is to determine long-term mortality following hospitalization due to acute exacerbations of COPD (AECOPD), as well as AECOPD mortality predictors. METHODS: We conducted a retrospective study by reviewing the medical records of all patients admitted with AECOPD in the University Hospital Complex of Santiago de Compostela in 2007 and 2008...

Aims: Alcohol is a risk factor for cardiac arrhythmias. Retrospective analyses suggest supraventricular arrhythmias consecutive to acute alcohol consumption, but prospective data are limited. We intended to prospectively associate acute alcohol consumption with cardiac arrhythmias. Methods and results: At the 2015 Munich Octoberfest, we enrolled 3028 voluntary participants who received a smartphone-based ECG and breath alcohol concentration (BAC) measurements. ECGs were analysed for cardiac arrhythmias (sinus tachycardia, sinus arrhythmia, premature atrial/ventricular complexes, atrial fibrillation/flutter) and respiratory sinus arrhythmia...

REVIEW
Sergio Conti, Atul Verma
Atrial fibrillation is the most common cardiac arrhythmia and the number of patients is expected to continuously increase in the next years. Catheter ablation is an effective, safe, and well-established treatment for patient with symptomatic and drug-resistant paroxysmal atrial fibrillation (PAF). Over the last decade, there was an increasing body of evidence demonstrating superiority of catheter ablation over antiarrhythmic drugs (AADs) in maintaining sinus rhythm. However, randomized clinical trials have not been conclusive to consider catheter ablation as a first-line therapy for PAF...

BACKGROUND: Catheter ablation has become the first line therapy in patients with symptomatic, recurrent, drug-refractory atrial fibrillation. Circumferential pulmonary vein ablation is still the standard approach in these patients. However, the results are not very favorable (especially in patients with persistent atrial fibrillation). Therefore, more complex ablation strategies and the usefulness of (short-term) adjunctive antiarrhythmic drug therapy are a matter of discussion. The aim of this study was to analyze whether short-term amiodarone therapy after catheter ablation (3 months) has a positive effect on the success rates after circumferential pulmonary vein ablation in patients with persistent atrial fibrillation...

There has recently been growing evidence that atrial fibrillation (AF), the most common cardiac arrhythmia, is independently associated with the risk of dementia. This represents a very recent frontier with high social impact for the number of individuals involved and for the expected increase in AF incidence in the next 40 years. Although a number of potential haemodynamic processes, such as microembolisms, altered cerebral blood flow, hypoperfusion and microbleeds, arise as connecting links between the two pathologies, the causal mechanisms are far from clear...

BACKGROUND AND PURPOSE: Stroke risk may increase shortly after warfarin initiation in nonvalvular atrial fibrillation patients. Because of the brief period and limited number of events, large samples are needed to study this effect. We compared 30-day rates of ischemic stroke between nonvalvular atrial fibrillation patients initiating warfarin to nonwarfarin comparators using an insurance claims database. METHODS: We identified nonvalvular atrial fibrillation patients via 1 inpatient/2 outpatient diagnosis claims from the MarketScan database, January 1, 2009, to December 31, 2012...

Propafenone is a Vaughan Williams class 1c antiarrhythmic medication widely used for treatment of arrhythmias. Although the long-term safety of propafenone use has not been established, it is commonly used for treatment of atrial fibrillation in patients with no structural heart disease. Propafenone is well known as pill-in-the-pocket treatment for its effect in terminating paroxysmal episodes of atrial fibrillation. Herein, we discuss an unusual adverse reaction to propafenone in a patient who presented with symptomatic bradycardia and hypotension...

Firstly, we would like to thank Bonello et al. for their comment on our recent publication. We completely agree that until now, data were contradicting regarding the impact of dabigatran on platelet reactivity. Additionally, we completely agree that during the last year, different groups have clearly shown enhanced platelet aggregation and platelet adhesion in dabigatran treated patients. [1-3] Furthermore, two different mechanisms have been described (enhanced platelet adhesion to the endothelium mediated by GPIb-α by Petzold et al...

BACKGROUND: Atrial fibrillation is common after oesophageal surgery. The aim of this study was to evaluate whether landiolol hydrochloride was effective and safe in the prevention of atrial fibrillation after oesophagectomy, and to see whether a reduction in incidence of atrial fibrillation would reduce other postoperative complications. METHODS: This single-centre study enrolled patients scheduled for transthoracic oesophagectomy in a randomized, double-blind, placebo-controlled trial between March 2013 and January 2016...

BACKGROUND: Patients with degenerative aortic stenosis (AS) referred for transcatheter aortic valve implantation (TAVI) typically have advanced cardiac and vascular adverse remodeling and multiple comorbidities and, therefore, might not recover a normal functional capacity after valve replacement. We sought to investigate the prevalence, the predictors, and the prognostic impact of residual impairment of functional capacity after TAVI. METHODS AND RESULTS: Out of 790 patients undergoing TAVI with impaired functional capacity (NYHA II-IV) at baseline, NYHA functional class improved in 592 (86...

Aims: Left atrial (LA) diameter is a predictor of atrial fibrillation (AF) recurrence following radiofrequency catheter ablation (RFA). However, LA volume (LAV) is more accurate in assessing LA size. Studies evaluating LAV as a predictor of AF recurrence are contradictory; therefore, we performed a meta-analysis to assess whether LAV is an independent predictor of AF recurrence following RFA. Methods and results: All studies reporting LAV/LAV index (LAVi) as a predictor of AF recurrence following RFA were included...

Aims: Outcome of persistent atrial fibrillation (AF) ablation remains suboptimal. Techniques employed to reduce arrhythmia recurrence rate are more likely to be embraced if cost-effectiveness can be demonstrated. A single-centre observational study assessed whether use of general anaesthesia (GA) in persistent AF ablation improved outcome and was cost-effective. Methods and results: Two hundred and ninety two patients undergoing first ablation procedures for persistent AF under conscious sedation or GA were followed...
