AIMS: Left atrial catheter ablation of the pulmonary veins (PV) has evolved as an important therapeutic option for the treatment of @entity955 ( @entity955 ). We aimed to investigate the incidence and predictors of @entity999 associated with PV catheter ablation, detected by diffusion-weighted magnetic resonance imaging (DW-MRI). METHODS AND RESULTS: We performed a prospective analysis of 53 consecutive @entity1 with persistent or paroxysmal @entity955 that underwent PV ablation and post-procedural cerebral @entity422 day after lasso catheter-guided ostial PV ablation. @entity1 were analysed for possible demographical, medical, echocardiographical, and procedural predictors of @entity887 . A mean of 3.5 +/- 0.5 PVs were ablated per @entity1 . In six @entity1 , DW-MRI depicted new clinically silent microembolism after PV ablation (11%). The number of ineffective medical antiarrhythmic agents prior to ablation procedure was significantly higher in the @entity887 group (3.3 +/- 0.5 vs. 2.2 +/- 1.4, P = 0.014). @entity301 ( @entity301 ) was more frequent in @entity1 with @entity999 (33 vs. 2%, P = 0.031); left ventricular volume (130 +/- 12 vs. 103 +/- 26 mL, P = 0.002), and septal wall thickness (13.0 +/- 1.4 vs. 7.9 +/- 4.8 mm, P = 0.025) were significantly increased. CONCLUSION: This study shows a high incidence of silent micro- @entity887 after PV ablation. @entity301 , @entity5988 , and @entity1184 were potential predictors of this complication.
