A vascular ring is a rare congenital anomaly encircling the trachea and esophagus by vascular structures, which may not be patent. One common form is a right aortic arch with aberrant left subclavian artery (RAA-ALSA), often arising from a diverticulum of Kommerell (DoK) and completed by a left ductus or ligamentum arteriosum. The DoK, an embryonic remnant of the left dorsal arch, may further compress the airway and esophagus. The aim of this study is to compare DoK morphology across intracardiac anatomic variants in RAA–ALSA patients, hypothesizing that intracardiac lesions altering fetal ductal flow impact DoK size, with right-obstructive lesions yielding a smaller DoK and left-obstructive lesions a larger DoK.

Prenatal screening and diagnosis of fetal anomalies rely upon ultrasound studies (US). US is generally considered safe during pregnancy. It is estimated that 1% of all neonates are born with a congenital heart defect that makes careful standardized examination of the fetal heart a mandatory step during all fetal US exams. US examination of the fetal heart requires at least analysis of the fetal situs, the four-chamber (4CH) view and the three-vessel view (3V). In the evaluation of the fetal heart, it is now worldwide accepted that the three-vessel trachea (3VT) view should be obtained, if technically feasible, in supplement of the other classical fetal cardiac views (4CH, 3V).

The relevance of adding the 3VT view is that some congenital cardiovascular abnormalities, potentially significant for fetal outcome, can only be diagnosed with this view; these malformations include vascular rings and right aortic arches. Read More
