Popis: Highlights • Coxiella burnetti should be evocated in patients with acute myocarditis in epidemic countries. • The prognosis of myocarditis is uncertain Treatment with corticoid could be useful in myocarditis to avoid the evolution to dilated cardiomyopathy. • Myocarditis in certainly under estimated in patients with Q fever.
We report the case of a 19-year-old healthy adolescent, living in an urban area, admitted because of acute chest pain and extensive anterior ST elevation. Coronary arteries were normal on coronary angiography; troponins were very high, echocardiography revealed a preserved global systolic function but an alteration of the longitudinal strain in the inferolateral wall. Cardiac MRI confirmed the diagnosis of acute myocarditis. As part of the etiological workup, Coxiella burnetii serology showed an acute infection. The diagnosis of Coxiella burnetii myocarditis was retained and the patient was treated with doxycycline and corticosteroid therapy. The myocardial localization of this germ is unusual but can be serious, hence the interest of a Coxiella serology in endemic countries face to any acute myocarditis.
