  2. Right-sided aortic arch - Wikipedia

    en.wikipedia.org/wiki/Right-sided_aortic_arch

    Right-sided aortic arch is a rare anatomical variant in which the aortic arch is on the right side rather than on the left. During normal embryonic development, the aortic arch is formed by the left fourth aortic arch and the left dorsal aorta. In people with a right-sided aortic arch, instead the right dorsal aorta persists and the distal left ...

  3. Aortic arches - Wikipedia

    en.wikipedia.org/wiki/Aortic_arches

    A double aortic arch; occurs with the development of an abnormal right aortic arch in addition to the left aortic arch, forming a vascular ring around the trachea and esophagus, which usually causes difficulty breathing and swallowing. Occasionally, the entire right dorsal aorta abnormally persists and the left dorsal aorta regresses in which ...

  4. Aortic arch - Wikipedia

    en.wikipedia.org/wiki/Aortic_arch

    The aortic arch is the connection between the ascending and descending aorta, and its central part is formed by the left 4th aortic arch during early development. [12] The ductus arteriosus connects to the lower part of the arch in foetal life. This allows blood from the right ventricle to mostly bypass the pulmonary vessels as they develop.

  5. Double aortic arch - Wikipedia

    en.wikipedia.org/wiki/Double_aortic_arch

    Isolated double aortic arch without associated intracardiac defects is a vascular anomaly that can be corrected without the support of cardiopulmonary bypass. [citation needed] For surgical division of the narrower left aortic arch in a typical double arch patient with a dominant right arch, the patient is placed on the right side.

  6. Vascular ring - Wikipedia

    en.wikipedia.org/wiki/Vascular_ring

    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. [citation needed]

  7. Aortic arch anomaly - peculiar facies - intellectual disability

    en.wikipedia.org/wiki/Aortic_arch_anomaly...

    Aortic arch anomaly - peculiar facies - intellectual disability is a rare, genetic, congenital developmental anomaly that is characterized by heart abnormalities, cranio-facial dysmorphia, and intellectual disabilities. No new cases have been reported since 1968.

  8. Tetralogy of Fallot - Wikipedia

    en.wikipedia.org/wiki/Tetralogy_of_Fallot

    right-sided aortic arch, in 25%; coronary artery anomalies, in 10%; a patent foramen ovale or atrial septal defect, in which case the syndrome is sometimes called a pentalogy of Fallot [46] an atrioventricular septal defect; partially or totally anomalous pulmonary venous return

  9. Overriding aorta - Wikipedia

    en.wikipedia.org/wiki/Overriding_aorta

    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.
