Prediction of sinus rhythm maintenance after radiofrequency ablation in patients with atrial fibrillation using speckle tracking echocardiography and dynamics of left atrial structural and functional parameters

radiofrequency 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...

Usefulness of left atrial speckle-tracking echocardiography in patients with atrial fibrillation

Catheter ablation for the treatment of persistent atrial fibrillation: Maintenance of sinus rhythm with left atrial appendage and coronary sinus isolation after multiple ablation procedures

Introduction After seminal research demonstrated the pulmonary veins (PVs) and PV antrum contained substrates that can initiate and perpetuate paroxysmal atrial fibrillation (AF) in the majority of patients, catheter ablation with circumferential pulmonary vein isolation (PVI) has become the cornerstone treatment for the management of paroxysmal AF. However, in patients with persistent and long...

Prediction of successful cardioversion and maintenance of sinus rhythm in patients with lone atrial fibrillation.

OBJECTIVE We aimed to prospectively investigate the predictive value of echocardiographic parameters for the prediction of successful cardioversion and long-term sinus rhythm (SR) maintenance in patients who have experienced a lone episode of atrial fibrillation (AF). MEASUREMENTS AND RESULTS Clinical and echocardiographic data, including mean left atrial appendage (LAA) peak flow velocity an...

Acute effects of left atrial radiofrequency ablation on atrial fibrillation.

INTRODUCTION Acutely, when left atrial ablation is performed during atrial fibrillation (AF), the AF may persist and require cardioversion, or it may convert to sinus rhythm or to atrial tachycardia/flutter. The prevalence of these acute outcomes has not been described. METHODS AND RESULTS Left atrial ablation, usually including encirclement of the pulmonary veins, was performed during AF in ...
