Sudden death and acute myocarditis: a unique forensic case of double origin of coronary arteries

Description

The doubling of the right coronary artery is a rare congenital coronary anomaly. Generally, this malformation is asymptomatic and therefore benign. But, in some cases, it constitutes a real silent killer. The aim of this study is to show how the double right coronary artery can cause fatal events without clinical signs of its presence. We reported the association between this anomaly and the acute necrotising myocarditis. In the forensic literature, cases of sudden death associated with the double coronary origin are not described.1 2

We reported the case of a sudden death in a 14-year-old girl. At autopsy, the heart showed greyish areas and the histopathological surveys demonstrated the doubling of the right coronary artery (figures 1–4). The left ventricular myocardium showed a phlegmonous exudative inflammation, large necrotic areas and interstitial leucocyte infiltration, which...
