Correlation Between Electroanatomic Mapping and Histology A 5-μm histological slide with Masson’s trichrome staining at a level ∼2.5 cm above the left ventricular apex is shown in an anterior-posterior projection (middle). The histological specimen shows complex scar architecture with areas of surviving subendocardial myocardial bundles (single and double solid arrows) separated by subendocardial scar (dashed arrow). The histological section corresponds to the dashed line of the electroanatomic map created with microelectrodes, similarly showing areas of bipolar voltage amplitude ≥1.5 mV separated by areas of low voltage (<0.5 mV). (Right) Higher magnification (10×) of the rectangle in the middle panel, showing surviving myocardial bundles in the subendocardium.
