Can echocardiography predict the presence or absence of endocardial fibroelastosis in infants <1 year of age with left ventricular outflow obstruction?

This study assesses the use of echocardiography in detecting endocardial fibroelastosis in 32 infants with obstructive left-sided lesions. The data demonstrate that neither endocardial echo-brightness nor geometric variables of the left ventricle allow for accurate prediction of the presence of endocardial fibroelastosis.
