Records were reviewed, comparing fetuses with TA\u2010II<\/jats:styled-content>\/III<\/jats:styled-content> and those with PA\u2010VSD<\/jats:styled-content>, with particular focus on: 1) characteristics of the overriding vessel, 2) appearance of the semilunar valves, 3) competence of the semilunar valves, 4) presence of major aortopulmonary collateral arteries (MAPCA<\/jats:styled-content>), 5) main pulmonary artery being without antegrade flow, 6) site of arterial branching from the great artery and 7) other minor features, such as cardiac axis or associated anomalies.<\/jats:p><\/jats:sec>Results<\/jats:title>Seventeen fetuses were identified, eight with TA\u2010II<\/jats:styled-content>\/III<\/jats:styled-content> and nine with PA\u2010VSD<\/jats:styled-content>. Among the eight fetuses with TA\u2010II<\/jats:styled-content>\/III<\/jats:styled-content>, seven had abnormal valves and six had valve regurgitation, compared with none of the nine PA\u2010VSD<\/jats:styled-content> fetuses. Five TA\u2010II<\/jats:styled-content>\/III<\/jats:styled-content> fetuses had early branching to supply the lungs, whereas most fetuses with PA\u2010VSD<\/jats:styled-content> had more distal branching. Notably, in six of the TA\u2010II<\/jats:styled-content>\/III<\/jats:styled-content> fetuses, the root of the single great artery originated predominantly from the right ventricle, while all but one of the PA\u2010VSD<\/jats:styled-content> fetuses had typical equal overriding of the VSD<\/jats:styled-content>. The main pulmonary artery was without antegrade flow in two cases with PA\u2010VSD<\/jats:styled-content>. Finally, four cases with PA\u2010VSD<\/jats:styled-content> had MAPCA<\/jats:styled-content>, in two of which this was identified prenatally.<\/jats:p><\/jats:sec>Conclusion<\/jats:title>Identification of abnormal arterial valves or valve regurgitation, site of origin of branching, presence of overriding of the great artery, a main pulmonary artery without antegrade flow and MAPCA<\/jats:styled-content> are helpful in differentiating between TA\u2010II<\/jats:styled-content>\/III<\/jats:styled-content> and PA\u2010VSD<\/jats:styled-content>.
