"Normal" Values for Aorta
"Normal" Values for Aorta

Hi Harmony - first of all, I'm no expert, but my echo's list the "normal" parameters for the AR as anthing below 3.7. Mine is currently sitting at 4.0, but my cardio isn't overly concerned about it. She (and other cardios I've consulted with) start to get worried once it gets up around 5.0.
Personally, I think they should be more concerned about where you STARTED from, rather than where you end up. For example: if your "normal" AR measurement was 3.6, then a change to 4.4 probably isn't anything to be too concerned about, but if your "normal" AR was 2.0 and it has enlarged to 4.4, then surely that's a pretty big change.
I don't know if other problems with your heart make a difference (ie. MVR, cardiomyopathy...) but it never hurts to question your doctors.

The normal diameter of the aorta and what represents "normal" versus an aneurysm is an important topic. There is often confusion about this, and the use of a "normal" size range on these reports adds to that confusion.
What is normal for an individual depends on body size, gender, and age. Around 2.5 cm is a good ball park number for the ascending aorta in adults. Some people will be smaller, around 2.0 cm, and others larger.
There is more than one way to define when the aorta is so enlarged it should be called an aneurysm, but there is fairly general agreement that 4 cm represents an aneurysm.
The normal range on an echo report is just listing the variation in the size of the aorta in different people. When they give a size like 3.7 cm, that might be normal for someone who is probably a large adult male. A petite female may be 2.0 cm. So, if they want to include a range that covers everyone, they might say 2.0 cm to 3.7 cm. However, as an individual, you are not interested in the range in the population. You need to know what number is normal for you, and whether some part of your aorta has begun to enlarge.
My husband's aorta had begun to enlarge, but we were never told because even though it had grown since the last echo, it was still within the so-called normal range, so nothing was said. As an adult, his aorta should not have been growing significantly, and that should have been the first indication that he had a problem with his aorta. The next time it was measured, he had a large aneurysm! (We know this now because we got all his reports years later, at the time of his aneurysm diagnosis.)
Yes, you want to know what your normal size is/should be for you individually, you want to know if it is enlarging, and also how fast it is growing. A fast growth rate is also a concern, regardless of size, because aortic tissue can be unpredictable.
I hope this helps!
