Abstract

Objectives-The purpose of this study was to investigate the ability to depict the 4- chamber and 3-vessel and trachea views of the fetal heart using 3-dimensional sonography. Methods-Three-dimensional color Doppler volumes of the fetal heart were acquired prospectively in 31 fetuses between 19 and 25 gestational weeks. The initial plane consisted of the 4-chamber view. Postprocessing included navigation within the volume solely in plane A in the caudal direction to visualize the stomach and in the cephalic direction to the plane of the 3-vessel and trachea view to visualize the pulmonary artery, the aorta, the V shape and color of the arches, the superior vena cava, and the trachea. The feasibility of showing these organs was evaluated. Results-The estimated time for volume acquisition and manipulation was about 60 seconds. The detection rates for the 4-chamber view, stomach, 3-vessel view, trachea, and V sign were 100%, 93.5%, 92.0%, 77.4%, and 83.9%, respectively, with interobserver agreement of 0.76 to 1.0. Conclusions-We describe a simple technique in which a single sweep on 3-dimensional sonography starting at the level of the 4-chamber view can visualize the situs, stomach, 4-chamber view, and transverse view of the outflow tracts of the heart.
