The occurrence and maintenance of AF is favored by both the degree of left atrial (LA) dilation and the association of fibrotic lesions of the myocardium. The LA is a marker of adverse cardiovascular events in patients with AF. Atrial remodeling can be electrical (shortening atrial refractory), structural (altering geometry and altering collagen content) and contractile (loss of contractility). Cardiac imaging plays a central role in the clinical management of this arrhythmia. Echocardiography represents the routine imaging technique used in patients with AF, with a role in detecting LA dysfunction and cardiac structural changes that predispose to this arrhythmia, also having the ability to predict the maintenance of sinus rhythm after cardioversion and after ablation.</p></abstract>
