A Case of Eosinophilic Infiltration of the Right Heart: Diagnostic and Management Considerations.

Abstract

Loeffler first described "fibroplastic parietal endocarditis with blood eosinophilia" in 1936. This we now know refers to the most common cardiac manifestation of an uncommon condition, the so-called hypereosinophilic syndromes. This condition typically results in a restrictive cardiomyopathy affecting the left heart, but here, we present an unusual case of a 65-year-old woman with chronic hypereosinophilia of at least 2 years, who presented with right heart failure as a result of eosinophilic endomyocardial infiltration of her right ventricle. We explore the diagnostic pathway and look at the literature on management.
