Overview[edit | edit source]

An overriding aorta is a congenital heart defect where the aorta is positioned directly over a ventricular septal defect, instead of over the left ventricle.

The result is that the aorta contains some blood from the right ventricle, which reduces the amount of oxygen in the blood.

It is one of the four conditions of the Tetralogy of Fallot.

Heart: Tetralogy of Fallot; Left Anterior Oblique with VSD and Overriding aorta (MRI)

Cardiac chambers and connections	Persistent truncus arteriosus - Double outlet right ventricle (Taussig-Bing syndrome) - Transposition of the great vessels (dextro, levo)
Cardiac septa	Ventricular septal defect - Atrial septal defect (Lutembacher's syndrome) - Atrioventricular septal defect (Ostium primum) - Tetralogy of Fallot - Eisenmenger's syndrome
Right: pulmonary and tricuspid valves	pulmonary valves (stenosis, insufficiency) - tricuspid valves (stenosis, atresia) - Ebstein's anomaly
Left: aortic and mitral valves	aortic valves (stenosis, insufficiency, bicuspid) - mitral valves (stenosis, regurgitation) - Hypoplastic left heart syndrome
Other congenital malformations of heart	Dextrocardia - Levocardia - Cor triatriatum
Great arteries	aorta (Patent ductus arteriosus, Aortic coarctation, Interrupted aortic arch, Overriding aorta, Aneurysm of sinus of Valsalva, Vascular ring) - Pulmonary atresia
