[Candida albicans endocarditis after treatment of complete atrioventricular canal]. / Endocardite à Candida albicans après cure de canal atrioventriculaire complet.

Infective endocarditis is rare in children, it is rarer after a surgical treatment of atrioventricular canal, and it is exceptional that Candida albicans is the etiologic agent. This is a serious infection found in congenital heart disease with or without surgery. It is potentially lethal, despite diagnostic and therapeutic advances. We report a case of infective endocarditis due to C. albicans after the treatment of a congenital systemic atrioventricular canal in a child with trisomy 21. The diagnosis was suspected on clinical manifestations and cardiac auscultation. Confirmation was provided by positive blood cultures and echocardiography. The large size of the vegetation in the patient was in favor of a fungal etiology, blood cultures allowed to identify the fungus. This observation illustrates a poorly understood disease, with very poor prognosis and which is a potential complication of heart surgery. The improved prognosis should be achieved by shortening the time to diagnosis and optimizing the therapeutic support.
