Background. The aorta is considered pathologically dilated if the diameters of the ascending aorta and the aortic root exceed the norms for a given age and body size. A 50% increase over the normal diameter is considered aneurysmal dilatation. The shape of the dilated aorta in children with bicuspid aortic valve does not occur in a uniform manner and multiple shapes are seen, with the two most common shapes being S2 and S3. In children less than six years of age, the most common shape is S2, while the S3 shape is more common in older children and adolescents, suggesting that the aortic shape changes with age.

Dilated aorta in child

Among these,49 situation. Most physicians will advise caution to a patient with an enlarged aorta (the major artery in the body). (An enlarged aorta can occur in people with Marfan syndrome, Turner syndrome, coarctation of the aorta, or a bicuspid aortic valve.) There is no proven link between exercise and harmful outcome from an enlarged aorta. Late results with the David II remodeling valve-sparing procedure in children have been compro- mised by late root dilatation. (Ann Thorac Surg 2004;77:168– 76).

Since one of the main risk factors for aortic aneurysms involve old age, children diagnosed with it usually develop aneurysms along with some other previously underlying condition.

The dilated or aneurysmal ascending aorta is at risk for spontaneous rupture or dissection. The magnitude of this risk is closely related to the size of the aorta and the underlying pathology of the aortic wall. The occurrence of rupture or dissection adversely alters natural history and survival even after successful emergency surgical treatment.

WHAT IS KNOWN: • Aortic dilation is frequent in bicuspid aortic valve and other congenital heart defects. • Aortic dilation can be seen in several connective tissue disorders. Limited information Dilatation of the ascending aorta is extremely rare and may be associated with bicuspid aortic valve. This report evaluates the incidence of dilatative aortic root and ascending aortic pathology in patients younger than 18 years and analyzes the results obtained after repair and replacement strategies. Methods: Between 1/1995 and 12/2002, a total of 752 operations on the thoracic aorta were performed in adult and pediatric patients.

Aortic root dilation (AoD) is frequently an incidentally discovered, asymptomatic finding in that is seen on various imaging modalities [].The anatomy of the aortic root includes the annulus, sinuses of Valsalva, sinotubular junction and ascending aorta [], with the size being a function of a patient’s biologic variables such as height, age, BSA, and gender [1, 2]. 2013-07-01 · The dilated aorta in adults with bicuspid aortic valve has been shown to have different shapes, but it is not known if this occurs in children. As the shape of the dilated aorta in children with bicuspid aortic valve has not been described, it is the purpose of this study to: (1) Describe the shape of the dilated aorta, (2) associate the shape Se hela listan på ahajournals.org Se hela listan på ehowremedies.com In older children, an alternative to surgery may be catheter-based therapy.

2008-12-05 · In children, aortic anomalies include native coarctation, residual findings after surgery or catheter-guided interventions, connective tissue diseases such as Marfan syndrome and dilatation of the aortic root associated with aortic valve anomalies or occurring after surgery for congenital heart disease, such as the arterial switch operation or the Ross procedure [ 1 – 4 ]. The finding of a dilated aorta in childhood can be seen with: 1) no other structural heart disease 2) a bicuspid (2 leaflet) aortic valve- very common, 3) Marfan or other connective tissue disorder.
