Un mode de révélation rare de la maladie de Wegener: une myocardite associée a une endocardite fibroblastique

We report, through this observation, a rare case of Wegener's disease revealed by myocarditis associated with fibroblastic endocarditis. The patient was initially admitted to hospital with global heart failure. The ECG showed atrial flutter rhythm disorder. Echocardiographic examination revealed non-dilated left ventricle with severe dysfunction and positive troponin dosage. Severe renal failure was discovered fortuitously and required hemodialysis. It was associated with an inflammatory anaemia confirmed by serum ferritin and myelogram. c-ANCA dosage was strongly positive, confirming the diagnosis. Chest CT scanning objectified right basal pneumonia. After starting appropriate treatment, including corticotherapy and immunosuppressive treatment, evolution was favorable with the normalization of left ventricular systolic function. Although obvious clinical cardiac events are rare, cardiac involvement in Wegener's disease is described, requiring rapid diagnostic orientation and rigorous knowledge of this serious disease.
