Abstract

The circular-shaped PulseSelect™ PFA catheter has demonstrated comparable efficacy to traditional thermal catheter ablation in achieving pulmonary vein isolation (PVI), while preventing thermally mediated complications. However, this catheter does not have any objective parameters to confirm real-time tissue-catheter contact. We report a case in which PVI was achieved through PFA using optimal biplane fluoroscopic angulations which were more useful for accurately assessing and adjusting the position and rotation of the circular catheter electrodes than the conventional fluoroscopic angulations.

Keywords: atrial fibrillation; catheter ablation; fluoroscopic angulation; pulmonary vein isolation; pulsed field ablation.
