AB  - Pulsed Field Ablation (PFA) can establish pulmonary vein isolation via irreversible electroporation and is believed to reduce overall complications; however, periprocedural stroke has also been reported after PFA procedures. Assessment of microembolic signals (MES) measured by transcranial doppler (TCD) allows to monitor cerebral embolization during the procedure and to identify higher risk procedural steps. This study was designed to compare the incidence of MES during different procedural steps between two different PFA systems and radiofrequency ablation (RFA).Pulmonary vein isolation was performed either using either high-power short-duration radiofrequency ablation (HPSD RFA), or PFA using a variable loop circular catheter (VLCC) or a circular multielectrode array catheter (CMAC). MES were compared during transseptal puncture, ablation, left atrial mapping, and introduction/retraction of catheters. Neurological examination was performed pre and post ablation for all patients including the National Institutes of Health Stroke Scale (NIHSS). Fifty-six consecutive patients (19 female (34
