In-vivo myocardial lesion characteristics. A: short-axis gross pathology of two adjacent lesions in the IVS. B: magnification of IVS demonstrating lesion measurements (d, depth; s, sub-endocardial surface sparing; l, length; w, width; t, thickness is not shown, but was measured by sectioning serial short-axis cross-sections). C: Quantification of gross pathologic lesion characteristics. Graph bars are means with error bars as standard deviation.
IVS: inter-ventricular septum
