Aims: To assess the association and the predictive value of plasma homocysteine (Hcy) levels with LA/LAA thrombus in non-valvular Atrial fibrillation (AF) patients with low CHA2DS2-VASc score. Methods and results: Eight hundred and eighty-eight consecutive patients in non-valvular AF with CHA2DS2-VASc score of 0 and 1 were enrolled. All patients routinely underwent transthoracic echocardiography and transoesophageal echocardiography. A total of thirty-two patients had LA/LAA thrombus...

Aims: Maps obtained by means of electroanatomic high-density mapping (HDM) systems have shown their use in the identification of conduction gaps in experimental atrial linear lesion models. The objective of this study was to assess the use of HDM in the recognition of reconnection gaps in pulmonary veins (PV) in redo atrial fibrillation (AF) ablation procedures. Methods and results: One hundred and eight patients were included in a non-randomized study that assessed the recognition of reconnection gaps in PV by means of HDM compared to a control group that received conventional non-fluoroscopic guidance with a circular multipolar catheter (CMC)...

The prevalence of sleep-disordered breathing (SDB) is high in patients with cardiovascular diseases. Typical symptoms like daytime sleepiness can be absent and those patients may report unspecific, therapy-resistant symptoms related to their underlying disease. Particularly sleep-related symptoms like nocturia, nocturnal dyspnea and pectangina can be present. Based on the results of recently published studies, the treatment of central sleep apnea in patients with symptomatic, systolic heart failure by adaptive servo-ventilation is no longer recommended...

Atrial fibrillation (AF) is a major risk factor for ischemic stroke and associated with a 5-fold higher risk of stroke. In this retrospective cohort study, the incidence of and risk factors for ischemic stroke in patients with AF were identified. All patients (≥30 years old) without previous stroke who were diagnosed with AF in 2007-2013 were selected from the National Health Insurance Service-National Sample Cohort. To identify factors that influenced ischemic stroke risk, Cox proportional hazard regression analysis was conducted...

OBJECTIVE: The diagnosis of coronary artery disease (CAD) in atrial fibrillation (AF) patients using coronary computed tomography angiography (CCTA) requires a large exposure dosage or repeated examinations. This study evaluates the feasibility of using low-dose CCTA in the double prospectively ECG-triggered high-pitch spiral acquisition mode (Double Flash Spiral mode). METHODS: Twenty-eight AF patients with suspected CAD were recruited. Double Flash Spiral mode (tube voltage 100 kVp) and iterative reconstruction was used for CCTA examination...

Background Atrial fibrillation (AF) is a frequent complication after cardiac surgery. We explored the incidence and predictors of post-operative AF at 30-day follow-up in an unselected multi-centre cohort of patients undergoing elective coronary artery bypass grafting (CABG) in contemporary practice. Methods and results We enrolled 740 consecutive patients scheduled for elective CABG with or without valve surgery. Cardiac rhythm was continuously monitored for 15 days after surgery by an ambulatory event loop recorder...

OBJECTIVE: To compare the risk and cost of stroke/systemic embolism (SE) and major bleeding between each direct oral anticoagulant (DOAC) and warfarin among non-valvular atrial fibrillation (NVAF) patients. METHODS: Patients (≥65 years) initiating warfarin or DOACs (apixaban, rivaroxaban, and dabigatran) were selected from the Medicare database from 01/01/2013-12/31/2014. Patients initiating each DOAC were matched 1:1 to warfarin patients using propensity score matching to balance demographics and clinical characteristics...

The effectiveness of oral anticoagulation therapy with warfarin (a vitamin K antagonist) in the treatment of thromboembolic disease, including stroke prophylaxis in patients with atrial fibrillation is well recognised. However, warfarin has a narrow therapeutic window and an unpredictable anticoagulation response, which make it difficult to achieve and maintain optimal anticoagulation. Various dietary factors, including sudden changes in eating patterns, can significantly alter anticoagulation control, thereby potentially exposing patients to the risk of bleeding or thromboembolic complications...

Anticoagulation, reducing the risk of thromboembolic events in patients undergoing cardioversion, is a cornerstone of peri-cardioversion management in patients with atrial fibrillation. We aimed to analyse published data on the efficacy and safety of direct oral anticoagulants (DOACs) in patients undergoing cardioversion. We performed a systematic review of randomized prospective clinical trials (RCTs) comparing DOACs with warfarin and reporting data on post-cardioversion outcomes of interest. Outcomes of interest were stroke, systemic thromboembolic events and major bleeding...

Some diseases, such as renal colic and atrial fibrillation, display an association with microclimatic variations. In particular, despite a correlation has been reported between incidence of primary spontaneous pneumothorax (PSP) and meteorological variations, the evidence remains poor and conflictual. The aim of this study was to assess the influence of day-by-day meteorological variations on the number of visits for PSP in the Emergency Department (ED). All PSP cases were retrieved from the hospital database from January 2008 to December 2014...

INTRODUCTION: The BIFA concept (box isolation of fibrotic areas) supplementing pulmonary vein isolation (PVI) was implemented in atrial fibrillation (AF) patients with fibrotic atrial cardiomyopathy (FACM) to improve catheter ablation outcomes. METHODS AND RESULTS: 92 patients with FACM underwent PVI+BIFA. We investigated patient characteristics (58 persistent/34 paroxysmal,68±8y,LA 44±7mm,CHA2 DS2 -VASc 2.6±1.3,FACM I:15.2%,II:53.3%,III:26.1%,IV:5.4%), periprocedural data concerning fibrosis extent/distribution and their impact on outcome...

BACKGROUND: Patients with chronic kidney disease (CKD) have worse adverse cardiovascular outcomes after coronary artery bypass grafting (CABG). However, the adverse cardiovascular outcomes between off-pump coronary artery bypass grafting (OPCAB) versus on-pump coronary artery bypass grafting (ONCAB) in these patients have been a subject of debate. METHODS: We undertook a comprehensive literature search of PubMed, Embase, and the Cochrane Library database to identify all relevant studies comparing techniques between OPCAB and ONCAB in CKD patients...

Atrial fibrillation (AF) is one of the most common cardiac arrhythmias, and carries an increased risk of cardiogenic embolism. Oral anticoagulants (OACs) including warfarin and/or non-vitamin K antagonists can prevent the majority of these events. The Saitama AF Registry was a community-based survey of patients with AF in Saitama City, which represents an urban community in Japan. A total of 75 institutions participated in the registry and attempted to enroll consecutive patients with AF from September 2014 to August 2015...

REVIEW
Andreea D Ceornodolea, Roland Bal, Johan L Severens
In Europe, 1-3% of the population suffers from atrial fibrillation (AF) and has increased stroke risk. By 2060 a doubling in number of cases and great burden in managing this medical condition are expected. This paper offers an overview of data on epidemiology and management of AF and stroke in four European countries as well as the interconnection between these dimensions. A search index was developed to access multiple scientific and "grey" literatures. Information was prioritised based on strength of evidence and date...

BACKGROUND: Relaxin-2 (RLX) is a peptide hormone that exerts beneficial anti-fibrotic and anti-inflammatory effects in diverse models of cardiovascular disease. The goal of this study was to determine the effects of RLX treatment on the susceptibility to atrial fibrillation (AF) after myocardial infarction (MI). METHODS: Mice with cryoinfarction of the left anterior ventricular wall were treated for two weeks with either RLX (75 μg/kg/d) or vehicle (sodium acetate) delivered via subcutaneously implanted osmotic minipumps...

OBJECTIVES: Exclusion of the left atrial appendage has been proposed to reduce the risk of stroke in patients with atrial fibrillation. The aim of this study was to evaluate the feasibility and efficacy of the AtriClip PRO·V device (AOD2), now in development, for left atrial appendage exclusion in a canine model. METHODS: The newest AtriClip design comprises a dual-spring mechanism that allows the clip to open into a 'V' shape while still providing equivalent force along the length of the beam...
