Prenatal diagnosis of endocardial fibroelastosis

Abstract

In a case of fetal heart failure caused by endocardial fibroelastosis, prenatal echocardiography clearly demonstrated a thickened endocardium. We therefore suggest that an abnormal endocardium may be detected in utero by ultrasound, thus representing an important clue in the differential diagnosis of fetal nonimmune hydrops and in the evaluation of pregnancies at risk for endocardial fibroelastosis.
