Abstract Background Ebstein's anomaly is a rare cardiac defect where the septal and posterior leaflets are displaced, towards the right ventricle. the leaflets are dysplastic and stuck to the ventricular wall. Its antenatal diagnosis is usually made through bidimensional echocardiography, which also has prognostic value. Recently, the technological breakthrough of three-dimensional ultrasound (3D-US) offered new diagnostic tools for congenital heart defects, less dependent on the ultrasonographer experience, when compared to two-dimensional ultrasound (2D-US). the spatio-temporal image correlation (STIC) technique allows the acquisition of the fetal heart volume and its structures as a 4D cineloop sequence showing the complete cardiac cycle. Inversion mode is a new image analysis tool for the examination of fluid-filled fetal structures that inverts the gray scale.Case report We present a case of Ebstein's anomaly diagnosed at 26 weeks of pregnancy through bidimensional echocardiography. We emphasize its main findings in 3D-US using the STIC and inversion mode techniques.
