Clinical implications
Given the comparable prevalence of GH after CBA of the LA roof in
addition to PVI, our results suggest that CBA of the LA roof can be
performed safely. In patients with a lower LA roof, however, clinicians
should consider the risk of GH after ablation. In addition, patients
with GH may still experience GH-related symptoms for a while after
ablation. To reduce the incidence of GH after ablation, we recommend
performing CBA of the LA roof under LET monitoring.
