Does radiofrequency ablation improve efficacy and reduce complications compared to antiarrhythmic drug therapy in patients with atrial fibrillation?
Radiofrequency ablation is reported to have higher efficacy and lower complication rates than antiarrhythmic drug therapy for atrial fibrillation.
Studies of RFA for treatment of atrial fibrillation report higher efficacy rates than do studies of AAD therapy and a lower rate of complications.
Calkins et al. (Wed,) studied this question.
