What is a dilated aortic root?

Otherwise known as an aortic root aneurysm, a dilated aortic root is when the first section of the aorta, where the aortic valve resides, becomes enlarged. When this enlargement reaches a critical size, there is a risk of it rupturing or tearing, leading to a life-threatening situation.

What is dilated aorta?

Abstract. 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.

What is normal aortic root dilation?

Aortic root dilatation at the sinuses of Valsalva is defined as an aortic root diameter above the upper limit of the 95% confidence interval of the distribution in a large reference population. In adults, a diameter of 2.1 cm/m2 has been considered the upper normal range in ascending aorta.

Why does aortic root dilate?

The primary cause of noninflammatory aortic root dilation is Marfan disease; the major causes of inflammatory aortic root dilation include giant cell aortitis, Takayasu’s disease, and syphilis. In these conditions, the inflammatory process generally does not affect the valve itself.

What are the symptoms of an enlarged aorta?

Other symptoms that may be associated with an enlarged aorta may include: Feeling nauseated or vomiting if they have an abdominal aortic enlargement and having a feeling of fullness. A rapid heart beat that is more than usual because of the compression of the blood vessels that are affected.

What causes aortic root dilation?

Some of the causes of aortic root dilation include chronic hypertension, aortitis (inflammation of the aorta, which can be caused by diseases such as syphilis), chest injury, aortic dissection (sudden tearing of the wall of the aorta, caused by degenerative vascular disease), and Marfan syndrome.

What is treatment for aortic root dilation?

Keyhole Surgery Approach to the Dilated Aortic Root. Depending on how large the aortic root aneurysm has become, and the severity of any symptoms associated with the presence of aortic valve regurgitation, surgery will be required as the aneurysm, once dilated, will not reduce on its own. The traditional treatment is called aortic root and aortic valve replacement through a full breastbone incision.

What is mildly dilated aorta?

Mild aortic ectasia is defined as an enlargement of the aorta that is mild in degree. This condition is associated with aortic aneurysm. This is because, generally, if the aneurysm diameter is greater than 1.5 times a normal aorta’s size, it is known as an aneurysm.
