Lesion effects in terms of local impedance variations after pulsed-field ablation during pulmonary vein isolation: a case report.

ABSTRACT:

Background

To date, no information is available on highly localized impedance (LI) measurements during the ablation of pulmonary veins (PVs) via a new form of energy such as electroporation by means of pulsed-field ablation (PFA).

Case summary

A 55-year-old man with a history of paroxysmal atrial fibrillation was admitted to our hospital for PV isolation (PVI). The procedure was performed with the new multi-electrode PFA catheter (FARAWAVE™). Before energy delivery, a high-density map of the left atrium was constructed with the Rhythmia™ system, while the IntellaNAV Mifi™ OI catheter was used to assess the baseline LI values of the four PVs. A manual tag was used to record the exact position where the IntellaNAV™ catheter measured the LI values for each segment of the vein b
