Atrial fibrillation (AF) is the most common type of tachyarrhythmia among patients with a cardiology profile. AF causes significant changes in the atrial myocardium – remodeling. The concept of atrial remodeling includes changes at several main levels: electrical remodeling, mechanical remodeling, structural remodeling, as well as endocrine and vegetative changes. Modern interventional methods of treating AF demonstrate high efficiency, provide «freedom from arrhythmia» in the long term and improve tolerance of relapses. Long-term persistence of AF reduces the chances of success of catheter treatment methods due to electrical, mechanical and structural remodeling of the atria. Perhaps, upon achieving reverse remodeling of the atria after restoration and maintenance of the rhythm, these chances will increase significantly. This issue currently remains open and requires additional research.
