Totally endoscopic ablation of left atrium via left chest for lone atrial fibrillation.

Surgical treatment is effective and less invasive for lone atrial fibrillation because of the emergence of the endoscopic technology and the adoption of new type of energy. On the basis of these improvements, we developed a new surgical ablation procedure by endoscopy for lone atrial fibrillation. The procedure enrolls only three ports on the left chest wall, which can provide pulmonary vein isolation, resection of the left atrial appendage, ganglionic plexus ablation, and make ablation of left atrium with direct vision. A total of 45 procedures were successfully performed. We reported the technique and result of the procedure.
