Is 3.8 CM upper normal limit for mid ascending aorta (in adults) when measured by cardiac MRI and 3.7 CM when measured by echocardiogram?If no, what is

BSA: Those numbers are in the ballpark of the upper limit of normal, but the best answer depends on body surface area.

While 3.7 cm may be normal for one person, particularly if they are tall, it may be enlarged for another person, particularly if they are short. ...Read more

Follow up ? Re diagnosis of mild ectasia (3.8x3.7 cm) on ascending aorta via cardiac ct: have had chest x-rays in past years (2010) with only normal results. Is this something an X-ray could miss?

Yes: The degree of ascending aortic enlargement is small and would no be expected to be picked up on a regular chest x-ray. A ct scan or MRI would be needed to reliably image a mild aortic enlargement of the size you mention. Follow up would be with repeat ct scan in 6 months and then yearly after that if no dramatic enlargement was seen in first 6 months. You should be on a beta blocker (medication). ...Read more

Loeys Dietz child and my ascending aorta is dilated. Any knowledgable drs. In Atlanta?

Sibley Heart Center: Sibley Heart Center (with Emory University) has an excellent reputation. I'm not from the area and don't know if they have any special center for connective tissue disorders (like Loeys-Dietz, Marfan or Ehlers-Danlos), but that would be a good place to start. Medical treatment and follow-up may be sufficient if the dilatation is not severe. Good luck. ...Read more
