Figure 6 Three-Dimensional Scar Map Demonstrating Viable Myocardial Channel Across Lateral Scar
Endocardial voltage map demonstrates area of continuous lateral scar as defined by classical voltage criteria (red area) with adjacent yellow-to-blue border zone (A). Positron emission tomography-derived 3-dimensional scar map in corresponding view confirms a lateral scar ("hole"; see the Methods section) but demonstrates a bridge of viable myocardium crossing the presumed scar area (white arrow, B). After registration of voltage map and 3-dimensional positron emission tomographic scar map, a bridge of metabolically alive tissue can be seen after successful registration traversing in the middle of the presumed voltage-defined myocardial scar (red, C). RV = right ventricular.
