A CT MT was performed in each patient before VT ablation. The CT MT 3D anatomical model, including MT\u00a0layers, was merged with the 3D electroanatomical and EBVM. Different predefined cut\u2010off settings for scar definition on EBVM were used to identify the optimal ones, which showed the best overlap in terms of scar area with the different MT\u00a0layers.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A cut\u2010off value of &lt;0.2\u2009mV demonstrated the best correlation in terms of scar area with the 2\u2009mm thinning on CT MT (<jats:italic>p<\/jats:italic>\u2009=\u2009.04) and a cut\u2010off of &lt;1\u2009mV best overlapped with the 5\u2009mm thinning (<jats:italic>p<\/jats:italic>\u2009=\u2009.003).
