Paediatric presentation of cardiac involvement in hypereosinophilic syndrome.

ABSTRACT

Eosinophilic endomyocarditis is extremely rare in paediatrics. This case report aims to present the sequential changes from thrombotic to fibrotic stages of the cardiac involvement in a child with hypereosinophilic syndrome. Endomyocardial fibrosis progressively aggravated the severity of the mitral regurgitation. Bioprosthetic valve replacement was finally performed without recurrence of cardiac complications despite a late relapse of the underlying disease.
