Limitations
This study has limitations. First, this study is a single center clinical trial with limited follow-up period and comparatively small simple size that may introduce patient selection bias. Second, the clinical setting was specific to China, so our results should be understood in that context. Finally, because there were few episodes of thromboembolism or bleeding, our study does not have sufficient power to detect a difference with the low rate of complications observed according to different clinical decisions after ablation guided by the BigThumb. High-quality research is needed to understand the efficacy of coagulation strategies guided by the BigThumb.
