Macroscopic and microscopic findings of the heart. a: Macroscopic haemorrhage in the posterior pericardium in situ at the autopsy. b: Gross findings of the heart after fixation. The cut surface of the heart after fixation shows black-red discoloration (arrowhead) in the entire circumference of the pericardium and pericardium-side myocardium. c: Scanning magnifications of the heart with haematoxylin-eosin (HE) staining. d: Schematic illustration of the microscopic pathology. The red dots indicate the microscopic haemorrhage, the blue rectangle indicates the thrombus, and the green arc indicates the contraction band necrosis. LV; left ventricle, IVS; interventricular septum, RV; right ventricle. e and f: Low- and high-power views of the haemorrhage in the cardiomyocytes. The haemorrhages were found in the pericardium and pericardium-side myocardium, which is compatible with the discolouration in macroscopic observation. Scale bars indicate 100 μm (e, f)
