case_images: Macroscopic and microscopic features of the ruptured heart. a The probe passes through the rupture site at the base of the right ventricle. There is significant pericardial hemorrhage. The tricuspid valve is seen centrally. b High power photomicrograph of the infarct showing myocardial necrosis and a heavy polymorphonuclear infiltrate

case_images: A slit-like rupture of the myocardium at the base of the right ventricule associated with epicardial hemorrhage was identified (Fig. 1a). Microscopic examination of sections from the rupture site showed epicardial hemorrhage and contraction band necrosis with heavy polymorphonuclear leukocyte infiltrates typical of a recent acute myocardial infarction, approximately 48-72 h (Fig. 1b).
case_images: Microscopic features of the uninfarcted heart. a, b, c Medium power views showing interstitial edema with mononuclear cell infiltrates. d, e, f High power views of the mononuclear interstitial infiltrates. Rare polymorphonuclear leukocytes and eosinophils are present
