    dilatation of ascending aorta

    I recently had a heart scan. My overall score was 70.93... however, in the report the following was stated: There is a mild dilatation of the ascending aorta at the level of bifurcation of the pulmonary artery... I was told to follow up with my primary physician. I have an appointment but now for two weeks. I have been trying to research on this an becoming worried about what I'm reading.. any insight would be appreciated... I am 59yrs old, never smoked, exercise frequently.. overweight by prob 30lbs..

    RE: dilatation of ascending aorta


    "There is a mild dilatation of the ascending aorta......"

    In general here, an aortic aneurysm is a swelling, dilation (enlargement) or ballooning out of an area of the aorta.

    The normal aorta (largest artery in the human body, shaped somewhat like a cane) is about 1" in diameter. Identifiable parts or sections of the aorta include the aortic root, ASCENDING (goes upward) aorta, aortic arch (curved portion at the top of the aorta), descending aorta (going downward), thoracic aorta (chest area) and the abdominal aorta (stomach area).

    Diseased aortic tissue is characterized by degeneration of the cells composing the aortic wall. This diseased tissue is weak, lacking sufficient elastic components to stretch and contract well.

    The first indication of this abnormality may be a localized enlargement/dilation in the area of weakness. When it reaches a certain size (cm), this enlarged/dilated area is referred to as an aneurysm.

    A report back in 2000 said that the risk of rupture of aortic aneurysms (typically occurring in the abdomen, AAA) that measure 5 to 5.9 cm was low but escalates sharply for those aneurysms that measure 6 cm or more in diameter.

    Back in mid-2002 a study by the Department of Veterans Affairs reported that surgical correction is not recommended unless the aneurysm exceeds a certain size.

    The researchers said that the hazards/complications of surgery can be the greater threat unless the aneurysm is larger than 5.5 cm in diameter and that most of smaller aneurysms wouldn't rupture so the ultimate goal is to repair the AAAs/TAAs that will burst.
