Objectives The purpose of this article is to present our experience with normal and abnormal fetal cardiac structures reconstructed in the HD live silhouette mode (GE Healthcare Japan, Tokyo, Japan) with spatiotemporal image correlation (STIC). Methods Twenty‐two fetuses with normal hearts and 1 fetus with a congenital heart anomaly (Ebstein anomaly) at 20 to 36 weeks' gestation were studied in the HD live silhouette mode with STIC. Results In normal fetal hearts, 4 cardiac chambers and crisscross arrangements of the pulmonary artery and aorta were clearly identified. This modality facilitated visualization of the relationships and course of the outflow and inflow tracts, thus helping the operators more effectively understand the spatial relationships among the cardiac chambers and vessels. The opening and closing of mitral, tricuspid, pulmonary, and aortic valves were ascertained in the en face view of both atrioventricular valves and great vessels. In the fetus with Ebstein anomaly, a low attachment of the tricuspid valve and an enlarged right atrium were evident. Conclusions The HD live silhouette mode with STIC provides new visual experiences for physicians, owing to the anatomically clear depiction of fetal cardiac structures, and it may be an easier way to depict the spatial relationships among fetal cardiac chambers, great arteries, and veins.
