Introduction Our pilot study aimed to evaluate the role of local impedance drop in lesion
formation during pulmonary vein isolation with a novel contact force sensing ablation
catheter that records local impedance as well and to find a local impedance cut-off value that
predicts successful lesion formation. Materials and methods After completing point-by-point
radiofrequency pulmonary vein isolation, the success of the applications was evaluated by
pacing along the ablation line at 10 mA, 2 ms pulse width. Lesions were considered …

Pulmonary vein isolation (PVI) is the cornerstone treatment for paroxysmal atrial fibrillation
(AF). The effective lesion creation during the PVI is essential to reach optimal long-term
results. Purpose Our pilot study aimed to evaluate the role of local impedance drop in lesion
formation during pulmonary vein isolation with a novel contact force sensing ablation
catheter that records local impedance as well and to find a local impedance cut-off value that …
