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.
