Redo ablation procedure
The repeat ablation procedure was performed in a manner similar to the
index one. When AT persisted at the beginning of the procedure, it was
mapped using an EPstar Libero and Ensite NavX system. Along with
electrophysiological findings, catheters and systems were used to
confirm the status of the lesions created in the index ablation
procedure. Based on the operator’s judgment, ablation was performed for
novel or recurring lesions.
