We present an example of corrected transposition with twisted discordant atrioventricular connections in which both fetal and postanatal echocardiograms were obtained. We correlate the fetal echocardiograms with the postanatal echocardiograms, placing emphasis on the echocardiographic clues to the diagnosis which were present in fetal life. The diagnosis should be suspected when the cardiac chambers and greatarteries show an unexpected spatial relationship for the given segmental connections, and when the axes of opening of the atrioventricular valves are not parallel.
