About this trial

Pulmonary vein isolation remains the cornerstone of invasive treatment for atrial fibrlllation. Despite recent technological advances in the field of pulsed field ablation (PFA) pulmonary vein isolation durability and arrhythmia free success rates remain approximately at the level of previous years and the radiofrequency ablation era.

Isolation durability during PFA procedures might be enhanced by:

1. Intraprocedural monitoring contact of catheter electrode to atrial tissue. 2. Intraprocedural assessment of the transmurality of irreversible electroporation lesion.

The aim of our study is to use intracardiac electrogram (iEGM) based analysis for assessment of catheter-tissue contact and PFA lesion durability.

Eligibility criteria
