Echocardiographic considerations in demonstrating complex anatomy of criss-cross atrioventricular valves and discordant atrioventricular and ventriculoarterial relations.

The associated features of 1-looping of the ventricles (ventricular inversion) with D-transposition of the great vessels and criss-crossing atrioventricular valves are an unusual constellation of cardiac anomalies resulting in corrected transposition physiology. The following case presentation depicts the fetal and postnatal considerations of two-dimensional and color Doppler echocardiography in accurately detailing the complex intracardiac connections associated with this arrangement and also warns of the potential pitfalls in echocardiographic assessment.
