Given its increasing prevalence, atrial fibrillation (AF) requires increasing attention from general practitioners, internists and cardiologists. It is therefore essential to provide information about the latest advances in AF treatment. The treatment strategy anchored in the guidelines along the CC-to-ABC scheme (Confirm, Characterize - to - Anticoagulation, Better Symptom Control, Comorbidities Management) should also include early rhythm control. Catheter ablation has been established as a safe and effective therapy for restoring and maintaining sinus rhythm. Several studies have shown its superiority over antiarrhythmic drug therapy. By rhythm control, catheter ablation has the potential to improve patients´ quality of live and left ventricular function, as well as reduce the risk of stroke. For selected patients, particularly those with heart failure, catheter ablation is the first-line treatment. Successful AF treatment requires a proactive approach. Thus, it is important to become familiar with the CC-to-ABC scheme, as well as catheter ablation, as effective strategies for treating AF and improve patient prognosis.
