Is aortic aneurysms and asending valve the same?

An aortic aneurysm can happen as the name indicates anywhere along the aorta, the aorta “ascends” as it leaves the heart, bends and then “descends “, if the aneurysm is on the short “ascending side” then its called ascending. You also mentioned “valve” on the title but I assume that was a typo

The doctor stated the Ascending aorta is mildly dated. . They explained it as the valves are not closing completely. I’m so confused and scared.

This is very scary and I felt just as you do when I was first diagnosed, but I've found that you can't live in terror every minute of your life. Eventually your mind will relax and you'll adjust to your new normal. As Moonboy reminds us, knowing about the condition is crucial and you do.

Thank you for replying. I appreciate that.

Without giving medical opinion, I would like to say that "midly" seems to be at the lower end of the size scale. Something like average, mildy, moderately, severely, and more.
You should have a measurement of that from that doctor. Ask.
My understanding is the around 3 is average/normal, 3-4 is cause for medicinal intervention, 4-5 is the same but with frequent monitoring, 5 and over could mean consideration for planned surgery, and a higher number a concern for emergent surgery.
BUT IT ALL DEPENDS ON THAT CONVERSATION BETWEEN YOUR DOCTOR AND YOU.
!! WE ARE ALL DIFFERENT !!
Mine was 6.5 at the emergency room, I was in surgery within a few hours.

Thank you for all of your info its very helpful.my heart doctor said he’s monitoring my condition & put me on metoprolol Er succinate 25 mg and I’m on already on Lisinopril. He didn’t tell me a measurement / size scale. In fact he didn’t say much at all. I’m getting a second opinion in March. Hopefully I get more info. As I’m like more prepared on what to ask him
