Background Acute myocarditis is an inflammatory disease of the heart mostly diagnosed in young people, which can present as sudden death. The etiology includes infectious agents (mostly viruses), systemic diseases and toxins. We aim to characterize infants and children with myocarditis at post-mortem presenting as sudden deaths. Methods Retrospective evaluation of 813 post-mortems in infants and children dying suddenly and unexpectedly between 2009–2019. Data retrieved included histological features, microbiology and clinical history. Results 23 of 813 post-mortems reviewed corresponded to acute myocarditis and 1 to dilated cardiomyopathy related to remote Parvovirus infection. PCR identified enterovirus (7), parvovirus (7 cases, 2 also with HHV6 and 1 case with EVB), Influenza A (1), Parainfluenza type 3 (1). Two cases corresponded to hypersensitivity myocarditis, 1 was Group A Streptococcus and 5 idiopathic myocarditis. Enterovirus was frequent in infants (7/10), and in newborns was associated with meningoencephalitis or congenital myocarditis. More than 50% were less than 2 years of age and all remained clinically unsuspected. Conclusion Myocarditis represents almost 3% of all sudden pediatric deaths. Enterovirus and parvovirus were the most common viruses. This retrospective analysis showed that patients experienced viral symptoms but remained unsuspected, highlighting the need for more clinical awareness of myocarditis.

Abstract Background Because disease progression is so fast in sudden death of acute fulminant myocarditis, damage of myocardial cells is not evident in routine hematoxylin and eosin staining. To understand damage to myocardial cells and the mechanism of sudden death, immunohistochemical staining was performed for two forensic autopsy cases. Case presentation The patients were a healthy 5-year-old girl and 8-year-old boy. They suddenly died within 2 days of appearance of flu-like symptoms. An autopsy showed accumulation of yellowish-clear pericardial fluid containing fibrin deposits, fluid blood in the heart, and congestion of visceral organs. Histologically, minor necrosis or degeneration of myocardial cells with mainly lymphocytic infiltration was observed sometimes in tissue sections. Immunohistochemically, positive complement C9 staining and negative sirtuin 1 staining were found. These findings suggested wide damage of myocardial cells, even in regions with no marked changes in myocardial cells with hematoxylin and eosin staining. These areas corresponded to those with strong accumulation of lymphocytes. Conclusions Immunohistochemistry for complement C9 and sirtuin 1 might become a new tool for evaluating damage of myocardial cells of fulminant acute myocarditis.

Acute myocarditis is a rare complication of Escherichia coli urinary tract infection and sepsis. We report the case of a previously healthy 55-year-old female who presented to our emergency department with diarrhea and hypotension. The basic metabolic panel results showed an increase in inflammatory markers and an acute kidney injury. Urine and blood cultures grew Escherichia coli. The patient subsequently developed sudden chest pain and shortness of breath, diffuse ST-segment elevation, and cardiac enzymes’ elevation. Coronary angiogram was normal, and transthoracic echocardiogram demonstrated normal ventricular functions. Cardiac magnetic resonance imaging was highly suspicious of myopericarditis. The patient made a full recovery after infection treatment with intravenous antibiotics, aspirin, and colchicine.
