During pregnancy, prenatal ultrasound may reveal the abnormal course of the arch and this is the most common reason for identification of a right sided aortic arch nowadays. [3] Sometimes, when a right sided aortic arch is seen before birth, it can actually be a double aortic arch, sometimes a fetal MRI scan may be helpful if the ultrasound is ...
An overriding aorta is a congenital heart defect where the aorta is positioned directly over a ventricular septal defect (VSD), instead of over the left ventricle. [1] The result is that the aorta receives some blood from the right ventricle, causing mixing of oxygenated and deoxygenated blood, and thereby reducing the amount of oxygen delivered to the tissues.
an overriding aorta, which is where the aorta expands to allow blood from both ventricles to enter. At birth, children may be asymptomatic or present with many severe symptoms. [10] Later in infancy, there are typically episodes of bluish colour to the skin due to a lack of sufficient oxygenation, known as cyanosis. [2]
Type B: The aortic arch is interrupted between the left common carotid artery and the left subclavian artery. This is the most common form of the condition, and is the classification most often associated with DiGeorge syndrome. [2] [5] Type C: The aortic arch is interrupted between the innominate artery and the left common carotid artery. This ...
The severity of symptoms depends on the type of TGV, and the type and size of other heart defects that may be present (ventricular septal defect, atrial septal defect, or patent ductus arteriosus). Most babies with TGA have blue skin color (cyanosis) in the first hours or days of their lives, since dextro-TGA is the more common type.
A less common ring is present with a right aortic arch instead of the usual left-sided aortic arch. This compresses the esophagus and trachea because of the persistence of a ductal ligament (from fetal circulation) that may connect between the aorta on the front and the left subclavian artery posteriorly going to the left arm.

After a routine ultrasound at 24 weeks, Brailey and Louis Valenzuela learned some unexpected news about their baby, Arley — she had an olive-sized tumor on her heart known as pericardial teratoma.
In patients with double aortic arch the esophagus shows left- and right-sided indentations from the vascular compression. Due to the blood-pressure related movement of the aorta and the two arches, moving images of the barium-filled esophagus can demonstrate the typical pulsatile nature of the obstruction. The indentation from a dominant right ...
