Imaging was anonymized for blinded analysis of (1) LGE images, and (2) a 3D fusion image with LGE projected onto a segmented LA surface. Scans were categorized using both assessment techniques separately as pre‐ or postablation, and if postablation, whether lesions were in an ostial or WACA distribution.</jats:p><jats:p><jats:bold>\n            <jats:italic>Results:</jats:italic>\n          </jats:bold> LGE imaging was performed in 50 patients (aged 60 ± 10 years, 68% male, 24 underwent WACA and 26 had cryoablation). Sensitivity and specificity for detection of ablation lesions was 60% and 96% on LGE imaging. Sensitivity was higher using 3D fusion imaging (88%; P = 0.003). The proportion in whom lesions were both detected and the distribution correctly assessed as WACA or ostial was higher with 3D fusion imaging compared to LGE imaging (54% vs 28%; P = 0.014). There was no difference in the detection of radiofrequency ablation lesions compared to cryoablation lesions (58% vs 62%; P = 1.000).</jats:p><jats:p><jats:bold>\n            <jats:italic>Conclusion:</jats:italic>\n          </jats:bold> LGE imaging of atrial scar is not yet sufficiently accurate to reliably identify ablation lesions or to determine lesion distribution. <jats:italic>(J Cardiovasc Electrophysiol, Vol. 24, pp. 396‐403, April 2013)</jats:italic></jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699993769701638","@type":"Researcher","foaf:name":[{"@value":"ROSS J.
