Developmental phase



Assessment

Primary outcomes

Ablation success at 1 after after the index procedure. The definition of recurrence; any atrial tachyarrhythmia lasting more than 30 seconds after 3 month after the index procedure. The definition of procedural success; no recurrence without any anti-arrhythmic drugs.

Key secondary outcomes

1) acute left atrium-pulmonary vein electrical reconnection (time-dependent/ATP-dependent)
2) ablation time
3) energy
4) procedural time
5) complication associated with the procedure
6) contact force value

Interventions/Control_1

Every single RF application will be performed under CF guidance. Target CF of 20 g (with range of 10-30 g) and minimum FTI (force time integral) of 400 g s. VisiTag is utilized to visualize the catheter position stability and FTI.

Interventions/Control_2

Every single RF application will be lasted at least 5 seconds after the unipolar atrial EGM, recorded by the ablation catheter, which always demonstrates positive-negative morphology before ablation, became complete positive signal. VisiTag is utilized to visualize the catheter position stability.

Results

Unipolar signal modification was superior to contact force monitoring as an endpoint for radiofrequency energy deliveries during pulmonary vein isolation in patients with paroxysmal atrial fibrillation in terms of the 12-month recurrence free rate (85% vs. 70%, p=0.031).
