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.
