Myocardial infarcts (areas outlined in yellow) are observable in this ovine cardiac apex!

Using specialized histologic megacassettes to obtain very large samples (megasections), it is possible to analyze the whole cardiac apex and to offer an outstanding macro-micro correlation as well as a precise morphometric analysis of myocardial lesions.
