This will require further surgery or another procedure. In 0.5% of cases there are no serious complications associated with this disease, but in older patients there is a chance that arterial hypertension may not improve after the repair. In terms of hypoplasia of the aortic arch, 5 % of those treated require further procedures due to recoarctation. Blood pours through a tear in the inner layer, causing a bulge and weakness in that area of the aortic artery. Aortic dissection is a separation between the inner and middle layers of the aortic artery wall. This is done by using a patch to enlarge the narrowed section of the aorta. If there is a related ventricular septal defect, this is often closed during the same surgery. Once out of the operating room the mortality rate for this disease is 1%.Ħ-10% of patients will, however, go on to develop a new narrowing of the aorta (recoarctation). Aortic dissection is a life-threatening condition that can cause sudden death if it is not recognized and quickly treated. Following this, a metal stent is implanted in the area of coarctation to keep the vessel at the correct calibre. Hypoplasia of the aortic arch is repaired in the first two weeks of life. If this is the case, dilatation with high pressure balloons is performed to correct the narrowing. The ascending aorta begins above the aortic root and extends towards the neck until it begins to turn and give rise to the aortic arch. Or in other cases interventional haemodynamics is considered. Techniques to expand the narrowed area such as fitting a patch can also be used, In older patients, surgery is the preferred option and the procedure is similar to that for new-borns. The operation consists of resectioning the narrow segment of the aorta and then joining it to the healthy segments. In the neonatal period, patients usually need surgical treatment. Hypoplasia of the aortic arch is also diagnosed prenatally via echocardiogram without the need for further tests. This is usually done with an echocardiogram, but other tests tend to be carried out such as a CT angiogram or nuclear magnetic resonance imaging to define the characteristics of the coarctation. For this reason, it is diagnosed when high arterial pressure is detected during a routine check up. In the neonatal period, diagnosis is via transthoracic echocardiogram, but after this stage patients do not show symptoms. There are between 0.2 and 0.6 cases for every thousand live births. This is a common type of heart disease representing 5-6% of all heart pathologies. Who is affected by coarctation of the aorta? These patients first need to be stabilized and then treated. Plaque buildup on the artery walls causes the arteries to become less flexible. Causes of thoracic aortic aneurysms may include: Hardening of the arteries, called atherosclerosis. When this begins to close, circulatory collapse occurs due to the excessive load on the heart and insufficient circulation in the abdominal organs. Aneurysms can occur anywhere in the thoracic aorta, including near the heart, in the aortic arch and in the lower part of the thoracic aorta. It is also associated with other cardiac alterations such as patent ductus arteriosus, bicuspid aortic valve, ventricular septal defect and anomalies in the mitral valve.ĭuring the neonatal period, some patients’ blood flow may go towards the lower body, which is dependant on the ductus arteriosus.
