Closed-chest unilateral thoracoscopic ablation: box lesion with radiofrequency clamps only

Abstract

In this article, we describe the modified technique of a unilateral closed-chest thoracoscopic ablation and left atrial appendage closure including a box lesion that is made by radiofrequency clamps only for the treatment of atrial fibrillation. By abandoning the unidirectional pen devices and replacing these by radiofrequency clamps, we aim to further improve the procedural efficacy and shorten operation time while minimizing surgical exposure for the patient.
