Unusual case of aortic valve involvement in patient with Löffler's endomyocarditis: management, follow-up and short review of the literature.

Idiopathic hypereosinophilic syndrome (IHES) is an uncommon systemic disease which is characterised by blood eosinophilia and multiple clinical presentations. Cardiac involvement is the major cause of mortality and morbidity. Here we describe a 59-year-old man with symptoms of progressive dyspnea on exertion, and productive cough as an unusual case of Löffler endomyocarditis with a mass on the aortic valve which showed regression with treatment.
