A case of biventricular apical obliteration.

We present a case of Loëffler endocarditis in a 45-year-old man. This syndrome is characterized by unexplained prolonged and marked hypereosinophilia (>1500 eosinophils/mm), absence of a primary cause of hypereosinophilia and evidence of eosinophil-mediated organ damage. Detection of cardiac damage is based on electrocardiography, echocardiography, cardiac MRI and endomyocardial biopsy.
