![]() In patients who do not develop heart failure as newborns, coarctation may not be found until the child is several years old. ![]() Because these newborns are well until the ductus arteriosus closes, symptoms appear quickly. This can lead to heart failure and shock. When the ductus arteriosus closes, the left ventricle must suddenly pump against much higher resistance. ![]() In about 25 percent of cases of isolated coarctation, the narrowing is severe enough to cause symptoms in the first days of life. The age at which coarctation is found depends on the severity of the narrowing. Or not enough blood flow to the organs of the body.Ĭoarctation of the aorta is present from birth. If the narrowing is very severe, the ventricle may not be strong enough to do this extra work. When a coarctation exists, the left ventricle must work harder to create a higher pressure than normal to force blood through the narrow part of the aorta to the lower part of the body. Coarctation may also be seen as a part of more complex,Ĭoarctation of the aorta is common in some patients with genetic disorders, such as Turner's syndrome. The defects usually seen with coarctation are bicuspid aortic valve and Coarctation may also occur with other cardiac defects, typically involving the left side of the heart. In babies with coarctation, the aortic arch may also be small (hypoplastic). Coarctation may be caused by having extra ductal tissue. It has special tissue in its wall that causes it to close in the first hours or days of life. The ductus arteriosus is a blood vessel that is normally present in a fetus. This portion of the aorta is called the "juxtaductal" aorta. The aorta is the main blood vessel carrying oxygen-rich blood from the left ventricle of the heart to all the organs of the body.Ĭoarctation occurs most often in a short piece of the aorta just beyond where the arteries to the head and arms take off. ![]() Coarctation of the aorta is a narrowing of the aorta. ![]()
