![]() ![]() Cardiac catheterization: a thin tube is inserted into the heart through a vein and/or artery in either the leg or through the umbilicus (“belly button”).Pulse oximetry: a noninvasive way to monitor the oxygen content of the blood.Electrocardiogram (ECG): a record of the electrical activity of the heart.Echocardiogram: sound waves create an image of the heart.Signs and symptoms of interruption of the aortic archĭiagnosis may require some or all of these tests: Your team at the Cardiac Center will explain the specific anatomy of your child’s heart in detail. Wherever the disconnection occurs, the passage of oxygenated blood to the lower body is compromised, or literally interrupted.Ĭhildren with interruption of the aortic arch almost always also have a large ventricular septal defect (VSD), or a hole in the wall between the two lower, pumping chambers of the heart. Type C (least common): The disconnection is after the innominate artery (sometimes called the brachiocephalic artery).Type B (most common): The disconnection is after the left carotid artery.Type A: The disconnection is after the left subclavian artery.Three arteries, feeding the head, neck and arms, branch off directly from the aortic arch, in this order: innominate, left carotid, left subclavian. There are three types of interruption of the aortic arch, based on the location of the break in the aorta. After it closes, an infant with interruption of the aortic arch will quickly become very sick without medical intervention. This vessel exists in the fetus, but closes within hours or days of birth. ![]() The ductus arteriosus is an alternate route for oxygenated blood to reach the lower body. Arteries that deliver blood to the abdomen, legs, and other parts of the lower body branch off from the lower, descending aorta.Ī newborn can survive with a disconnection in the aorta as long as a blood vessel called the ductus arteriosus remains open. Arteries that deliver blood to the head, arms and other parts of the upper body branch off at the top of the arch. From the heart, the aorta arches up and then curves around and down. The aorta starts at the left ventricle (lower chamber) of the heart as one large vessel and branches into smaller vessels to carry blood to different parts of the body. In a child with interruption of the aortic arch, there is a disconnection (a break) between the top part of the aortic arch and the lower, descending aorta. 2007 Apr 28(4):123-131.The aorta is the main artery that carries blood with oxygen out of the heart to the body. Presentation of congenital heart disease in the neonate and young infant. Cincinnati Children’s Hospital Medical Center website. Healthy Children-American Academy of PediatricsĮvaluation of the infant for congenital heart disease (CHD). There are no known guidelines to prevent IAA. Lifelong monitoring by a doctor who treats the heart will also be needed. Any hole in the heart between the ventricles will also be closed. ![]() Surgery will also be done to form a connection between the 2 parts of the aortic arch. Keep some blood flowing through another blood vessel called the ductus arteriosus.The goal of treatment is to get blood to flow as it should. Your child's heart activity may be measured. Pictures may be taken of your child's chest. You will be asked about your child's symptoms and health history. Symptoms often appear within the first day or two after birth. The risk of this problem is higher in children who haveĭiGeorge syndrome. It happens in the fifth to seventh week of fetal growth. Heart Chambers and ValvesĬopyright © 2002 Nucleus Communications, Inc. Children with IAA may also have a hole in the wall between the right and left chambers in the heart. With IAA, the aortic arch is interrupted or incomplete. The aortic arch is part of the major blood vessel that helps move blood from the heart to the rest of the body. An interrupted aortic arch (IAA) is a rare heart defect. ![]()
