Endoscopic left atrial box lesion ablation may be feasible post-catheter failure; leaves open durability and need for prospective comparisons.
Total endoscopic ablation of atrial fibrillation is a treatment option in symptomatic patients after unsuccessful catheter ablation or when catheter ablation is considered inappropriate. We describe a technique of endoscopic ablation of the left atrium using temperature-controlled unipolar or bipolar radiofrequency. A left atrial box lesion encircling the pulmonary veins is created using three ports in the right hemithorax. The technical aspects and preliminary results of the procedure are discussed.
