1INTRODUCTIONLeft atrial catheter ablation (LACA) is an increasingly used therapeutic option to restore sinus rhythm in patients with atrial fibrillation (AF).Unfortunately, LACA causes clinically evident strokes in up to 1% of all patients. Furthermore, it is known that there is a high incidence of silent cerebral events (SCEs) detectable by diffusion‐weighted magnetic resonance imaging (DW‐MRI).A more recently introduced procedure is the laserballoon‐based pulmonary vein isolation (PVI) with a high success rate of 82.3% at 12 months follow‐up in patients with paroxysmal AF and 75% in patients with persistent AF. But until now only 3 studies have investigated the impact of laserballoon LACA on the incidence of SCEs reporting a range of 13.6 to 37%.Therefore, the aim of this registry was to gain more information about the incidence and severity of CEs using the laserballoon and to optimize the approach to reduce the CE risk.2METHODS2.1Patient populationWe enrolled 74 consecutive patients with paroxysmal or persistent symptomatic AF undergoing LACA using the laserballoon in this prospective nonrandomized registry at 2 centers in Germany.Exclusion criteria were as follows: preexisting left atrial (LA) thrombus, transient ischemic attack (TIA) or stroke in the last 6 months, any condition contraindicating chronic anticoagulation, any cardiac procedure within
