Long-term outcomes of remote magnetic navigation for ablation of XXXX .

@entity1 @entity262 @entity591 @entity4710 @entity943
BACKGROUND: Little is known about the long-term outcomes of catheter ablation of @entity4710 ( @entity4710 ) using @entity262 ( @entity262 ). METHODS: One hundred twenty @entity1 underwent catheter ablation of SVTs with @entity262 (Niobe, Stereotaxis, USA): atrioventricular nodal re-entrant @entity591 (AVNRT; n   =   59), @entity591 ( @entity591 ; n   =   45), and focal @entity591 ( @entity591 , n   =   16). The outcome of @entity591 with right free wall accessory pathway was compared with those of a group of 26 consecutive @entity1 undergoing manual ablation. RESULTS: Mean follow-up period was 2.2        1.4  years. Overall @entity943 -free survival was 86  %; @entity591 (77  %), AVNRT (96  %), and focal @entity591 (71  %). After the learning period (initial 50 cases), procedural outcomes had improved for @entity591 and AVNRT (91  % in overall group, 90  % in @entity591 group, 100  % in AVNRT group, and 68  % in focal @entity591 group). The recurrence-free rate was higher for the free wall accessory pathways than those of the other sites (92 vs. 73  %, log-rank P   =   0.06). Furthermore, when it is confined for the right free wall accessory pathway, @entity262 showed excellent long-term outcome (7/7, 100  %) compared to the results of manual approach (18/26, 69.2  %, log-rank P   =   0.07). CONCLUSIONS: @entity262 showed favorable long-term outcomes for the ablation of @entity4710 . In our experience, @entity262 -guided ablation may be associated with a higher success rate as compared to manual ablation when treating right-sided free wall pathways.
