patients have paroxysmal atrial fibrillation

English Abstract
Background and aim:
Atrial fibrillation(AF) causes structural, electrical and cellular remodeling in the atrium. Intra-and
interatrial conduction time evaluation which is measured by tissue doppler echocardiography indicates structural and elec-
trical remodeling. Paroxysmal atrial fibrillation (PAF) treated with rhythm control strategy in the meta-analysis has been
demonstrated that in ensuring and protection to sinus rhythm radiofrequency (RF) ablation superior to anti-arrhythmic. The
aim of this study was the evaluate the effect of pulmonary vein isolation applied with RF ablation therapy on atrial conduc-
tion time and to investigate effect of structural and electrically remodeling after treatment.
Methods:
Fifty-two patients with symptomatic PAF despite at least one antiarrhythmic drug and without structural heart
disease were included the study. Two patients were excluded because of complications during and after the operation.
CARTO 3D pulmonary vein isolation applied with RF ablation system performed 50 patients (28 women; mean age: 51.68
±
11.731; mean left atrial diameter: 36.79
±
4.318) were followed. In all patients measured intra-and interatrial conduction time
by tissue doppler echocardiography before and three months after the operation.
Results:
Patients who had RF ablation after three months measured all intra and interatrial conduction was a significant
reduction in the duration. (PA lateral

Conclusions:
The result of our study; the elimination of the AF starting mechanism by RF ablation of pulmonary vein
isolation in patients who not yet formed atrial fibrosis and permanent structural changes can be to slow, stop and even
brings to mind the possibility of recovery from AF-induced structural remodeling by providing stable sinus rhythm.
