PURPOSE: We evaluated the correlation between @entity358 ( @entity358 ) anatomy and acute and long-term success of @entity358 isolation (PVI) with two balloon-based ablation catheter techniques. METHODS: One hundred consecutive @entity1 were analyzed in two equal groups treated with either the second-generation cryoballoon (CRYO) catheter or the visually guided laser ablation (VGLA) catheter. All @entity1 underwent multi-detector computed tomography (CT) imaging. The primary and secondary efficacy endpoints were the procedural achievement of proven electrical isolation of all veins and freedom from @entity955 ( @entity955 ) within a 1-year follow-up period, respectively. RESULTS: Variant @entity358 anatomy was observed in 32  % of @entity1 in the CRYO group and in 40  % of @entity1 in the VGLA group. All PVs were targeted with either the CRYO catheter (n   =   199) or the VGLA catheter (n   =   206). One hundred ninety-three of 199 PVs (97  %) were successfully isolated in the CRYO group and 194 of 206 PVs (94  %) in the VGLA group (p   =   0.83). Over a 12-month follow-up, @entity955 recurrence was documented in 11/45 (24  %) and 7/43 (16  %) @entity1 in the CRYO and the VGLA groups, respectively (p   =   0.21). In the CRYO group, a larger left inferior @entity358 size was associated with worse long-term outcome (p   =   0.001). In the VGLA group, a larger left superior @entity358 size (p   =   0.003) and more oval right inferior @entity358 were associated with worse acute success (p   =   0.038). There was no absolute cutoff between @entity358 anatomy and clinical success. CONCLUSIONS: The variability of @entity358 anatomy did not significantly compromise acute success of PVI or @entity1 outcomes.
