The A4 and other similar (small) studies strongly support the launch of major trials of left atrial catheter ablation for the maintenance of sinus rhythm, reduction of cardiovascular hospitalizations and improved survival in patients with symptomatic recurrent atrial fibrillation. Will pharmacological therapies continue to have an important place in the management of atrial fibrillation?
