![]() If that happens, parents are referred to a cardiologist who will confirm the diagnosis after an echocardiogram is carried out. A baby will not usually have any symptoms.Ī right aortic arch is often identified during a 20-week ultrasound pregnancy scan.The pattern does not usually form a ‘vascular ring’.All the head and neck vessels are connected in the same position and provide blood to the correct part of the upper body.Right aortic arch with mirror image branching pattern A baby will not usually have any symptoms of this condition at birth.Ģ.This connection is present in all babies in the womb, but should close shortly after birth. The ductus arteriosus is a blood vessel that connects the pulmonary artery (main vessel supplying the blood to the lungs) to the aorta (main vessel supplying the blood to the body). The condition is called ‘vascular ring’ because of the ‘ring’ shape formed by the right aortic arch, the left subclavian artery and the ‘ductus arteriosus’. Vascular refers to the body’s network of blood vessels. The way the aorta and the left subclavian artery are positioned creates a vascular ring around the trachea and oesophagus (feeding tube). ![]() T he ‘left subclavian artery’ – the large vessel that supplies oxygenated blood to the left arm, is positioned abnormally but flow to the arm is not usually affected.The aorta, the large body vessel, branches to the right rather than the left.The features of a right aortic arch with aberrant left subclavian artery are: Right aortic arch with aberrant left subclavian artery Two of the most common types of right aortic arch 1. Your baby may have symptoms of this condition after birth. If this is the case, your cardiologist (specialist heart doctor) will explain this to you. Some babies with a right aortic arch may have other heart defects. What is a right aortic arch?Ī right aortic arch occurs when the aorta, the large vessel that takes oxygenated (red) blood from the left side of the heart to the body, branches off to the right rather than the left of the trachea (windpipe). As the heart pumps, the red blood is then forced into the aorta and pumped around the body. ![]() The oxygenated (red) blood from the lungs returns to the top left chamber (atrium), and then flows through the mitral valve into the left ventricle. The blood then flows into the right ventricle and is pushed towards the lungs via the pulmonary artery to pick up oxygen. Normal circulationĭeoxygenated (blue) blood returning from the body goes into the top right chamber (atrium) of the heart. This stops oxygenated (red) blood mixing with deoxygenated (blue) blood. The heart is a muscular pump that has four chambers – two collecting chambers at the top (the atria) and two pumping chambers at the bottom (the ventricles).īetween the atria and ventricles there is a wall, (septum), separating the left and right side of the heart. If your child has been diagnosed with a right aortic arch, we want to help you understand about the condition.
