Surgical treatment of permanent atrial fibrillation during cardiac surgery using monopolar and bipolar radiofrequency ablation

OBJECTIVE Permanent atrial fibrillation (pAF) is a serious problem in cardiac surgery: An incidence of 3.5% among all patients scheduled for open heart surgery, 9.8% in heart valve cases and 45.6% among patients with severe rheumatic mitral valve (MV) disease was observed in our institution. Our experience with radiofrequency (RF) ablation procedures to treat pAF in these cases is reported. M...

Radiofrequency ablation for treatment of atrial fibrillation.

INTRODUCTION Atrial Fibrillation (AF) is the most common cardiac arrhythmia which represents a major public health problem. The main purpose of this research is to evaluate the Radiofrequency (RF) ablation effects in the patients with chronic AF scheduled for cardiac surgery because of different heart diseases. METHODS The descriptive and prospective study was conducted on 60 patients with AF...

[Surgical ablation of atrial fibrillation using radiofrequency].

OBJECTIVE To evaluate the effectiveness of intraoperative atrial fibrillation ablation using radiofrequency during mitral valve procedure. This report describes the early and midterms results. METHODS Between September 2003 and September 2005, 15 patients with mitral disease were operated. All patients were in chronic atrial fibrillation and with congestive symptoms despite full medication. T...

Radiofrequency ablation in treatment of atrial fibrillation.

Beside heart failure and metabolic syndrome, atrial fibrillation is termed the cardiovascular epidemic of the twenty-first century. Its increased morbidity and mortality is alarming. The present, most effective therapy of atrial fibrillation is catheter ablation. Successful ablation of atrial fibrillation prevents the occurrence and progression of electrical, structural and mechanic myocardium ...

Atrial Fibrillation Left Atrial Versus Bi-Atrial Maze Operation Using Intraoperatively Cooled-Tip Radiofrequency Ablation in Patients Undergoing Open-Heart Surgery Safety and Efficacy

OBJECTIVES We sought to determine whether limited left atrial Maze surgery encircling each of the pulmonary veins, using cooled-tip radiofrequency (RF) ablation, is as effective as the bi-atrial approach? BACKGROUND The original Cox/Maze operation effectively restores sinus rhythm (SR) in patients with atrial fibrillation (AF). Ablation procedures aimed at eliminating pulmonary vein foci have p...
