This review summarises the current indications for catheter ablation in the treatment of atrial fibrillation (AF), its fundamental technical principles, and new technologies. The effects of rhythm control, which is superior to drug therapy in symptomatic paroxysmal and persistent AF, reduction in AF burden, and potential mortality/functional improvement are discussed; the fundamental role of pulmonary vein isolation, additional substrate ablation strategies in persistent AF, special considerations in patients with concomitant Structural heart disease (SHD) and heart failure, and new energies such as pulsed field ablation are evaluated. AF catheter ablation, performed in suitable patients, with optimal timing and in experienced centres, is a key part of modern AF management. It greatly improves symptoms and can positively affect prognosis in some groups. Advances in technology and personalised strategies are expected to improve effectiveness and reduce risks.
