AIMS The success rate of circumferential pulmonary vein ablation (CPVA) to treat atrial fibrillation (AF) ranges from 60 to 90%, depending on the series. The objective of the study was to identify predictors of AF recurrence after a standardized CPVA procedure. METHODS AND RESULTS A series of 148 consecutive patients undergoing CPVA for symptomatic(More)
AIMS The aetiology of atrial fibrillation (AF) remains unknown in some patients. The aim of the study was to identify new risk factors for developing lone AF (LAF). METHODS AND RESULTS A series of 107 consecutive patients younger than 65, seen in the emergency room for an episode of LAF of <48 h duration were included in the study. A group of 107 healthy(More)
OBJECTIVES We sought to assess differences in phenotype and prognosis between men and women in a large population of patients with Brugada syndrome. BACKGROUND A male predominance has been reported in the Brugada syndrome. No specific data are available, however, concerning gender differences in the clinical manifestations and their role in prognosis. (More)
AIMS There is insufficient evidence to implant a combined cardiac resynchronization therapy (CRT) device with defibrillation capabilities (CRT-D) in all CRT candidates. The aim of the study was to assess myocardial scar size and its heterogeneity as predictors of sudden cardiac death (SCD) in CRT candidates. METHODS AND RESULTS A cohort of 78 consecutive(More)
BACKGROUND Ablation of the pulmonary veins (PVs) for atrial fibrillation treatment is often combined with linear radiofrequency lesions along the left atrium (LA) to improve the success rate. The study was designed to assess the contribution of LA posterior wall isolation to the outcome of circumferential pulmonary vein ablation (CPVA). METHODS AND(More)
AIMS Atrial fibrillation (AF) ablation efficacy varies according to patients' clinical characteristics. Although the association of obstructive sleep apnoea (OSA) and AF is well established, data on AF ablation efficacy in OSA are scarce. The aim of this study was to clarify the effect of OSA on the outcome of AF ablation. METHODS AND RESULTS A series of(More)
AIMS Though right atrial appendage tachycardia (RAAT) has been described, no studies to date have focused on its clinical characterization. The aim of the present study was to analyze its clinical, electrocardiographic (ECG), and electrophysiologic (EP) characteristics and the results of radiofrequency ablation (RFA) in RAAT. METHODS AND RESULTS Out of(More)
Since its initial description in 1992 as a clinical syndrome involving a specific electrocardiogram (ECG) pattern and an increased susceptibility for ventricular arrhythmias and sudden cardiac death (SCD), the Brugada syndrome (BrS) has prompted much research activity aimed at defining the clinical, genetic, and molecular aspects of the disease. 1 Major(More)
AIMS The aim of this study is to determine the incidence of lone atrial fibrillation (LAF) in males according to sport practice and to identify possible clinical markers related to LAF among marathon runners. METHODS AND RESULTS A retrospective cohort study was designed. A group of marathon runners (n = 252) and a population-based sample of sedentary men(More)
AIMS The role of high-intensity exercise and other emerging risk factors in lone atrial fibrillation (Ln-AF) epidemiology is still under debate. The aim of this study was to analyse the contribution of each of the emerging risk factors and the impact of physical activity dose in patients with Ln-AF. METHODS AND RESULTS Patients with Ln-AF and age- and(More)
