fibrillation (AF) ablation, EAM overestimates scar
formation in the left atrium (LA) when compared to the
scar seen on late-gadolinium enhancement magnetic
resonance imaging (LGE-MRI). Of the
235 patients who underwent initial ablation for AF at our
institution between August 2011 and December 2012, we
retrospectively identified 70 patients who had
preprocedural magnetic resonance angiography merged with
LA anatomy in EAM software and had a 3-month postablation
LGE-MRI for assessment of scar. Ablated area was marked
intraprocedurally using EAM software and quantified
retrospectively. Scarred area was quantified in 3-month
postablation LGE-MRI. The mean ablated area in EAM was
30.5 +/- 7.5\% of the LA endocardial surface and the mean
scarred area in LGE-MRI was 13.9 +/- 5.9\% (P < 0.001).
This significant difference in the ablated area marked in
the EAM and scar area in the LGE-MRI was present for each
of the 3 independent operators. Complete pulmonary vein
(PV) encirclement representing electrical isolation was
observed in 87.8\% of the PVs in EAM as compared to only
37.4\% in LGE-MRI (P < 0.001). CONCLUSIONS: In AF
ablation, EAM significantly overestimates the resultant
scar as assessed with a follow-up LGE-MRI.",
