The extent of scar tissue was 7.7 [4; 18.5] %. The extent of GZ was 7.3 [5.5; 10.3] %. The infarct zone had heterogenic structure. The scar zone was mosaic and was surrounded by regions of GZ.
In 73% of patients (18 patients) VA origin was the zone of enhancement. It should be mentioned that in most cases the location of VA was endocardial surface of LV (14 patients). At the sane time some patients had epicardial origin of VA (4 patients). No relations between the depth of LV damage (enhancement transmurality) and the origin of VA was estimated.
However, data regading the structure of LV in the location of VA may be helpful for planning ablation. The thickness and structure of LV myocardium in planed ablatin site may give an opportunity to use optimal energy and decrease the risk of pericardial effusion of hemopericardium.
