![]() ![]() Once the baby is stabilized, the coarctation is treated with surgery. As the ductus remains open, it keeps the surrounding aorta from narrowing. If a coarctation is detected in a newborn, a medicine that is used to keep the ductus open, called prostaglandin E1, is given through an IV. Some people with coarctation of the aorta may also have cerebral (in the head) aneurysm. With aneurysm, the vessel wall weakens and it “balloons,” or forms a “sack,” making it vulnerable to rupture. Even when the narrowed artery is corrected, adults who were born with coarctation of the aorta may face ongoing health problems, including high blood pressure, weakening of the aorta wall and aneurysm. Without treatment to correct coarcation of the aorta, average life expectancy is 34 years. Progression and Possible Complications of Coarctation of the Aorta This allows more blood to reach the lower body than would otherwise pass through the narrowed aorta. The body tries to get blood around the coarctation by rerouting blood through other vessels such as the intercostal (under the ribs) arteries or other collateral vessels. However, if heart failure does not occur, some people may not have coarctation diagnosed until later in life, perhaps as an adult. The baby may become rapidly sick, breathing heavily and feeding poorly. If severe, coarctation of the aorta can cause heart failure in infancy as the heart must work too hard to try to get blood to pass through the area of narrowing. Coarctation of the aorta can be confirmed with tests such as an echocardiogramor by a cardiac MRI scan. The classic findings on a physical exam for coarctation of the aorta are high blood pressure in the arms compared to the legs and weak pulses felt in the legs. Also, it becomes difficult to feel pulses on the baby. They have feeding problems, fussiness, sweating, paleness and difficulty breathing. If this occurs, newborn babies can become sick. In some cases, the narrowing of the ductus causes the main aorta to also narrow where some of this ductal tissue has extended to the aorta, creating a coarctation. It should shrink and eventually close within the first few days of life. The ductus arteriosus is a blood vessel that is present in all newborns. Typically, the narrowed segment occurs where the ductus arteriosus connects to the aorta. However, the coarctation can cause problems with increased work of the heart and high blood pressure. ![]() The narrowed segment ( coarctation) is typically short, with the aorta opening up to normal size past the coarctation. Interruption of the aortic arch is typically treated with surgery to repair the problems of the aorta, as well as other related heart problems.Coarctation of the aorta is a congenital (present at birth) condition where there is narrowing of the aorta (the main blood vessel that carries oxygen-rich blood from the heart to the body). What are interruption of the aortic arch care options? Signs and symptoms of interruption of the aortic arch usually occur soon after birth, frequently presenting with a heart murmur, a rapid heart rate, gray and cold feet and legs, shortness of breath, problems with feeding, and being more sleepy and unresponsive than normal. It occurs during fetal development, and infants that have it often have other heart defects, as well. ![]() Interruption of the aortic arch appears to be a genetic disorder. What causes interruption of the aortic arch? When blood flow is cut off at any point along this arch, it is known as interruption of the aortic arch or an interrupted aortic arch (IAA). Also known as: interrupted aortic arch, IAA What is Interruption of the Aortic Arch (IAA)?Īs the aorta carries blood from the heart to the rest of the body, it arches upward before bending around and down. ![]()
