| Description | Atrial fibrillation is the most frequent disorder of heart rhythm with constantly increasing incidence and prevalence. Although pharmacotherapy remains the primary method of choice to treat the fibrillation it slowly becomes ineffective and may produce side effects and adverse events. The selective catheter ablation interferes with the pathophysiological mechanism of onset and preservation of atrial fibrillation and as a result it restitutes sinus rhythm. In paroxysmal atrial fibrillation we usually electrically isolate active ectopic foci in pulmonary veins antrums. In persistent or permanent form of atrial fibrillation we perform a more complex ablation because in these cases electrical and functional atrial remodelation has already developed. Besides performing wider circle leasions around the pulmonary veins antrums we proceed with another linear leasions in the left atrium, sometimes in the right atrium and coronary sinus, respectively. Such leasions affect reentry circles in atrial wall that help the fibrillation preserve. |
