Stridor is a common condition in infants that is caused by a double aortic arch narrowing or narrowing of the main artery in the heart, according to research published in J Surg Case Rep. Valloids were one of the first congenital anomalies surgically repaired. Deaths due to respiratory compromise are uncommon in patients with significant airway compression, but they can occur. Persistent respiratory symptoms, such as cough, dyspnea, and whining, are the most common after-care symptoms. In patients with double aortic arch repair, the lifestyle effects are minimal. The cause of this anomaly has remained a mystery. One study found chromosome 22q11 deletions in three of 22 patients with double Aortic Arch, implying that they have a chromosome 22q11 deletion. The symptoms are usually mild, and there is usually no sign of cardiovascular disease. When the embryonic aortic arch segments are abnormalally regressions, the aortic arch forms a persistent double arch. An obstruction in the upper airway causes an obstruction in the lower airway, which reduces expiratory flow and inspiratory inspiratory capacity. Trisomy 21 is one chromosomal abnormality that has been linked to double aortic arch. DiGeorge, velocardiofacial, and conotruncal anomaly face syndromes are caused by deletion of chromosome 22q11. On either side of the descending thoracic aorta, there may be a cervical arch, variable laterality of the descending thoracic aorta, coarctation of the major arch, and/or discontinuity of the central pulmonary arteries. In either arch, there may be an atretic (but persistent) segment as well as a patent arch. During double aortic arch formation, both the fourth arches and the dorsal aorta remain present. As part of embryogenesis, six pairs of pharyngeal arch arteries emerge along with the branchial pouch. On this ring, the esophagus and trachea are completely encircled by connected segments of the aortoethoracic arch. One of the most common forms of vascular ring is the double aortic arch. Treatment for a double aorta often involves surgery to repair or replace the affected arteries. This can cause problems with blood flow and may lead to heart failure. In people with a double aorta, the two aortas are connected side-by-side. The aorta is the main artery that carries oxygen-rich blood from the heart to the rest of the body. A double aorta is a congenital heart defect in which there are two aortas, instead of the usual one.
