Fetal and Postnatal Echocardiographic Diagnosis of Ebstein Anomaly of the Mitral Valve

摘要

Ebstein anomaly of mitral valve (MV) is an extremely rare congenital heart disease. In the current report, we present a case of Ebstein of MV that was diagnosed prenatally. Fetal echocardiogram showed that the posterior leaflet of MV was tethered to the lateral wall of left ventricle (LV) with downward displacement into LV cavity. Postnatal transthoracic and transesophageal echocardiograms confirmed the diagnosis with apical displacement of the level of coaptation MV into the LV cavity. To the best of our knowledge, fetal diagnosis of Ebstein anomaly of MV has not yet been reported in the medical literature.
