Right Aortic Arch with Anomalous Left Subclavian Artery and Ligamentum Arteriosum

This is a congenital variant of the heart's great vessels in which the aortic arch sits toward the right and is accompanied by a subclavian artery and a ligament in an abnormal position. Together they can form a "vascular ring" that encircles the trachea and esophagus.

Which specialist treats it? Its study falls to the cardiologist and the pediatric cardiologist, with support from the cardiovascular and thoracic surgeon when a broader evaluation is needed; the pediatrician usually detects the first signs.

How it shows up: In some cases it causes no discomfort, while in others it may be associated with difficulty breathing or swallowing, especially in childhood.

If a child shows these symptoms, it is worth discussing the case with these specialists to determine the appropriate tests.
