ABSTRACT
The Cox-Maze procedure and less complex modifications have gained widespread use as a treatment modality for patients with concomitant atrial fibrillation. Hypothermic or hyperthermic energy sources play a significant role in rapidly creating linear lesions. Endocardial ablation is easy to perform and effective with different energy sources. Epicardial techniques may simplify the procedure by allowing surgery on a beating heart. But epicardial fat and the heat sink effect of the flowing endocardial blood are obstacles to effective ablation. New devices using bipolar (irrigated) radiofrequency, microwave or laser energy, cryoablation or focused ultrasound are in clinical or pre-clinical stages and permit lesions to be created on a beating heart without cardiopulmonary bypass. Minimally invasive or video-assisted surgical techniques and effective devices for epicardial ablation will enable the treatment of patients suffering from lone atrial fibrillation. To facilitate the comparison between different techniques and devices, guidelines for reporting clinical results are necessary.
