Hypereosinophilic Syndrome: What to Expect in Echo

Abstract

Hypereosinophilic syndrome is characterized by eosinophilic tissue damage. The clinical presentation is variable. When there is cardiac involvement, which occurs in 40%–60% of cases, it is referred commonly as Loeffler's endocarditis. Recently, a unique case report was published by Dr. Garg et al., in which they described pulmonary valve involvement with thickening and stenosis detected by two-dimensional transthoracic echocardiography in an adult presenting with Loeffler's endocarditis. Based on this case report, we review this topic to elucidate various manifestations of hypereosinophilic syndrome, which we should expect during echocardiography.
