Anatomically corrected malposition of the great arteries: a challenging fetal diagnosis

Anatomically corrected malposed great arteries are uncommon and benign entity. Basically, this occurs with ventriculoarterial concordance in which the great vessels arise parallel instead of a twisting fashion. In this manuscript, we described two cases in which the antenatal diagnosis of anatomically corrected malposition of great arteries was suspected and confirmed during the postnatal period. During the fetal life, this diagnosis remains a challenge and this condition is often misdiagnosed as the transposition of the great arteries (TGA). Differently to TGA, anatomically corrected malposition of the great arteries may not require any cardiac surgical intervention depending on the associated cardiac anomalies. Indeed, postnatal examination for concerns related to anomalies that can be associated with this condition, such as anomalous origins of coronary arteries and left ventricular outflow tract obstruction, should be performed.
