Catheter ablation for paroxysmal atrial fibrillation: segmental pulmonary vein ostial ablation versus left atrial ablation.
BACKGROUND Segmental ostial catheter ablation (SOCA) to isolate the pulmonary veins (PVs) and left atrial catheter ablation (LACA) to encircle the PVs both may eliminate paroxysmal atrial fibrillation (PAF). The relative efficacy of these 2 techniques has not been directly compared. METHODS AND RESULTS Of 80 consecutive patients with symptomatic PAF (age, 52+/-10 years), 40 patients underwent...
متن کاملAssociation Between Left Atrial Stiffness Index and Atrial Fibrillation Recurrence in Patients Undergoing Left Atrial Ablation.
BACKGROUND Atrial fibrillation (AF) is associated with significant abnormalities of left atrial (LA) systolic and diastolic function. This study describes a novel measure, LA stiffness index, that estimates LA diastolic function and its association with clinical outcomes of catheter ablation. METHODS AND RESULTS A total of 219 AF patients referred for ablation (59% paroxysmal, mean CHA2DS2VAS...
متن کاملAblation of Paroxysmal and Persistent Atrial Fibrillation
Introduction Atrial fibrillation (AF) is the most common arrhythmia in humans. Its maintenance is thought to be due to multiple wavelets reentry occurring in both atria [1]. Previous studies have demonstrated the feasibility and efficacy of cryoablation to create lesions in both atria [2] and on the posterior wall of the left atrium [3], connecting the four pulmonary veins and the mitral annulu...
متن کاملradiofrequency atrial fibrillation ablation technique in patients with mitral valve surgery and left atrial reduction procedures
background: about half of all patients who undergo mitral valve surgery suffer from atrial fibrillation (af). cox described the surgical cut-and-sew maze procedure, which is an effective surgical method but has some complications. this study was designed to evaluate the efficacy of a substitution method of radiofrequency ablation (rfa) for patients undergoing mitral valve surgery with af. metho...
متن کاملRecurrent Post-Ablation Paroxysmal Atrial Fibrillation Shares Substrates With Persistent Atrial Fibrillation : An 11-Center Study.
INTRODUCTION The role of atrial fibrillation (AF) substrates is unclear in patients with paroxysmal AF (PAF) that recurs after pulmonary vein isolation (PVI). We hypothesized that patients with recurrent post-ablation (redo) PAF despite PVI have electrical substrates marked by rotors and focal sources, and structural substrates that resemble persistent AF more than patients with (de novo) PAF a...
