Spatiotemporal organization of the left atrial substrate after circumferential pulmonary vein isolation of atrial fibrillation.
BACKGROUND There is a paucity of data regarding the mechanism of maintaining atrial fibrillation (AF) after pulmonary vein isolation (PVI) in patients with AF. The aim of this study was to examine the impact of circumferential PVI on the left atrial (LA) substrate characteristics. METHODS AND RESULTS Seventy-two AF patients (age, 53+/-11 years) underwent mapping and catheter ablation using an...
متن کاملPulmonary vein isolation for atrial fibrillation.
Nonpharmacological treatment for atrial fibrillation (AF) has evolved dramatically over the past 20 years. Pulmonary vein isolation, a catheter ablation technique developed in the last decade, prevents focal triggers in the pulmonary veins from initiating episodes of AF. Although the procedure initially involved focal ablation with a catheter directly in the pulmonary veins, investigators subse...
متن کاملLeft atrial epicardial adiposity and atrial fibrillation.
BACKGROUND Atrial fibrillation (AF) has been linked to inflammatory factors and obesity. Epicardial fat is a source of several inflammatory mediators related to the development of coronary artery disease. We hypothesized that periatrial fat may have a similar role in the development of AF. METHODS AND RESULTS Left atrium (LA) epicardial fat pad thickness was measured in consecutive cardiac CT...
متن کاملLeft atrial passive emptying function determined by cardiac magnetic resonance predicts atrial fibrillation recurrence after pulmonary vein isolation.
BACKGROUND Although pulmonary vein isolation has become a mainstream therapy for selected patients with atrial fibrillation (AF), late recurrent AF is common and its risk factors remain poorly defined. The purpose of our study was to test the hypothesis that reduced left atrial passive emptying function (LAPEF) as determined by cardiac magnetic resonance has a strong association with late recur...
متن کاملPulmonary vein isolation without left atrial mapping
BACKGROUND One of the crucial points during in most approaches developed for ablation of atrial fibrillation (AF) is the ability to identify the pulmonary vein (PVs) and to accurately locate their ostia. OBJECTIVES The purpose of this case series was to investigate a simplified method for fusion of the multislice computer tomography (CT) derived 3D dataset with the electroanatomical map in or...
