Ultrasonic diagnosis of fetal Ebstein's anomaly in prenatal / 中华超声影像学杂志

ABSTRACT

Objective To explore the clinical value of ultrosonic diagnosis of fetal Ebstein's anomaly in prenatal.Methods The data of echocardiography and follow-up results of 6 fetal Ebstein's anomaly were retrospective analyzed,and their abnormal ultrasound imaging characteristic were summarized.Results Six cases were proved into Ebstein's anomaly by autopsy,including septal tricuspid leaflet displacement(2 cases),septal and posterior tricuspid leaflets displacement(3cases),septal and posterior and anterior tricuspid leaflets displacement(1 case).There were 4 cases combined with right ventricle dysplasia,1 case with atrial septal defect,1 case with pulmonary stenosis,and 4 cases with hydrothorax,ascibes and pericardial fluid.The echocardiography of fetal Ebstein's anomaly was characterized by right atrial enlargement,displacement of tricuspid valve attachment point,the distance ratio of between cardiac apex and bicuspid valve attachment point and between cardiac apex and tricuspid valve attachment point exceeding(1.8),forming typical atrialized right ventricle feature,color blood flow indicating severe tricuspid regurgitation with low initial point,large area and slow speed(mean speed(217.0)(cm/s).)Conclusions The fetal Ebstein's anomaly has characteristic sonogram.Ultrasonic diagnosis of fetal Ebstein's anomaly has great clinical value in prenatal.
