Prenatal and postnatal medical records, including echocardiographic and computed tomography (CT)\/magnetic resonance imaging (MRI) scan reports, were reviewed, and cardiac and extracardiac abnormalities and the results of genetic testing were recorded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of 55 consecutive pregnancies with a prenatal diagnosis of fetal RAA, six were lost to follow\u2010up, one was terminated and three were excluded due to lack of postnatal confirmation of AA anatomy. Of the remaining 45 pregnancies, AA anatomy was assessed postnatally by CT in 39, by MRI in one and by direct examination at cardiac surgery in five. A U\u2010shaped appearance was found in 37\/45 (82.2%) patients, all of which had a complete vascular ring (CVR). Of these 37 patients, on postnatal confirmation, 21 (56.8%) had RAA with Kommerell's diverticulum, left posterior ductus arteriosus (LPDA) and aberrant left subclavian artery (ALSA) (RAA\/LPDA\/ALSA), 11 (29.7%) had a double AA (DAA), four (10.8%) had RAA with Kommerell's diverticulum, LPDA and mirror\u2010image (MI) branching (RAA\/LPDA\/MI), and one (2.7%) had RAA with Kommerell's diverticulum, LPDA and aberrant left innominate artery (ALIA) (RAA\/LPDA\/ALIA). A V\u2010shaped appearance was found in 3\/45 (6.7%) patients, all of which had RAA with right DA not forming a CVR and MI branching. In the 5\/45 (11.1%) fetuses with neither U\u2010 nor V\u2010shaped appearance, RAA with left anterior DA arising from the left innominate artery and MI branching, not forming a CVR, was found. Twelve (26.7%) fetuses had a congenital heart defect (CHD). RAA forming a CVR (U\u2010shaped appearance) was associated with a septal defect in 6\/37 (16.2%) fetuses, while RAA not forming a CVR (V\u2010shaped appearance or no U\u2010 or V\u2010shaped appearance) was associated with major CHD in 6\/8 (75.0%) fetuses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In fetuses with RAA, V\u2010shaped appearance of the junction between the DA and AA indicates only that the transverse AA and DA run together on the same side of the thorax (trachea) while a U\u2010shaped appearance is always a sign of a CVR. Among fetuses with a CVR, RAA\/LPDA\/MI is more frequent than described previously. Finally, RAA forming a CVR is not usually associated with complex CHD, as opposed to RAA not forming a CVR.
