Autopsy findings. The perforating wound is indicated by an arrow (A–C). In the sectioned profile of the rupture site at the apex (B), transmural necrosis was seen in the anterior-lateral wall. A low power view of the same section with B is indicated by masson-trichrome stain (C). Microscopically, there was no contraction band necrosis in the border zone between infarct and non-infarct tissue on hematoxylin-eosin stain (D). The coronary tree shows an occlusion in the 2nd diagonal branch (arrow in E), the occlusive lesion has fibrous plaque, dissection, and thrombus on hematoxylin-eosin stain (F).
