Figure 1 Morphometric analysis of the extent of infarct transmurality. After scanning the section, two radii (black) were drawn from the center of mass (LV chamber) to the maximal circumferential extent of the infarct. The total transmural and infarct areas are shown enveloped by the blue and green lines, respectively. Mean transmurality extent (% transmurality) was defined as (infarct area/total transmurality area) x 100.
