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 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 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)
INTRODUCTION Echocardiography is widely used to optimize CRT programming, but it is time-consuming. This study aimed to correlate the optimal interventricular pacing (V-V) interval obtained by echo with the optimal V-V interval obtained by a simpler method based on the surface ECG. METHODS AND RESULTS Three V-V intervals were tested: LV preactivation at(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)
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)
BACKGROUND Some ventricular tachycardias (VTs) originating from the epicardium are not suitable for endocardial radiofrequency ablation and require an epicardial approach. The aim of this study was to define the ECG characteristics that may identify an epicardial origin of VTs. METHODS AND RESULTS We analyzed the 12-lead ECG recordings during epicardial(More)
INTRODUCTION Circumferential pulmonary vein ablation (CPVA) for atrial fibrillation (AF) consists of creating extensive lesions in the left atrium (LA). The aim of the study was to evaluate changes in LA contractility after ablation and their relationship with procedure outcome. METHODS AND RESULTS A series of 90 consecutive patients underwent cardiac(More)
BACKGROUND Catheter ablation (CA) and minimally invasive surgical ablation (SA) have become accepted therapy for antiarrhythmic drug-refractory atrial fibrillation. This study describes the first randomized clinical trial comparing their efficacy and safety during a 12-month follow-up. METHODS AND RESULTS One hundred twenty-four patients with(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)
