L´¨öffler's endocarditis: an unusual type of rectritive myocardiopathy

pp 87-91

Abstract

A patient aged 56 years old was hospitalized due to heart failure and persistent eosinophilia (between 2500 and 14000 eosinophils/mm³). After searching for a secondary cause of this hemathological finding, a diagnosis of hypereosinophilic syndrome (HES) was made. The echocardiogram (M and B mode) (Figures 2. and 3) showed left atrial and ventricular dilatation with obliteration of the left ventricle apex in B mode (Figure 3). The cardiac catheterism, ventriculography (Figure 4) and endomiocardial biopsy led us to the diagnosis of restrictive miocardiopathy secondary to HES, configurating the syndrome of Löffler's endocarditis. The patient received treatment with corticosteroids and hidroxyurea but finally died due to bronchopneumoniae and heart failure. Autopsic findings (Figure 5) confirmed the diagnosis.
