Objectives

Narrative objectives1

We aim to analyze the effect and safety of left atrial roof linear ablation utilizing the seconed-generation cryoballoon (Arctic Front Advance) and the radiofrequency catheter ablation with the irrigation and contact force sensor from the early to late term. If the linear ablation cannot achieve with assigned energy, using the other energy (crossover) and try to make complete linear blockline.
