Diagnosis of rare Loffler endocarditis by cardiac ultrasound: a case report and literature review

Abstract

Loffler endocarditis is a rare disease associated with high mortality rates, therefore early diagnosis and prompt treatment are crucial factors in managing this condition effectively. The clinical manifestations are nonspecific which can lead to misdiagnosis easily. Here we report a case of rare idiopathic hypereosinophilic syndrome with Loffler endocarditis as the first presentation, first suspected acute coronary syndrome, diagnosed correctly by cardiac ultrasound. The purpose is to improve our understanding of the ultrasound manifestations of this disease.
