Ablation 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 کاملPulmonary vein isolation for paroxysmal and persistent atrial fibrillation.
BACKGROUND The pulmonary veins (PVs) have been demonstrated to often play an important role in generating atrial fibrillation (AF). The purpose of this study was to determine the safety and efficacy of segmental PV isolation in patients with paroxysmal or persistent AF. METHODS AND RESULTS In 70 consecutive patients (mean age, 53 +/- 11 years) with paroxysmal (58) or persistent (12) AF, segme...
متن کاملPersistent Atrial Fibrillation Is Associated with Worse Prognosis Than Paroxysmal Atrial Fibrillation in Acute Cerebral Infarction
Background and Purpose. We hypothesized that patients with persistent atrial fibrillation (AF) suffer from more severe cerebral infarction than patients with paroxysmal AF due to differences in clot structure and volume. Methods. This study includes consecutive patients with acute cerebral infarction and persistent or paroxysmal AF documented by ECG any time prior to stroke onset. The National ...
متن کاملEvolution of Paroxysmal Atrial Fibrillation to Persistent or Permanent Atrial Fibrillation: Predictors of Progression.
Introduction: Paroxysmal atrial fibrillation (PAF) eventually progresses to persistent and permanent AF. The predictors of progression from PAF to persistent and permanent AF are poorly understood. Methods: Electronic medical records of 437 patients with PAF were reviewed in a retrospective cohort study. Patients were followed in time and progression to persistent/permanent AF was recorded. Dem...
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...
