Taking Care of Your Aorta 10/15/18 (Virtual Medical Symposium Series)
10:23-11:47
Now in Marfan and Loyes Dietz and familial aneurism syndrome, as I mentioned, this is an echocardiogram showing the aorta. This is the muscle part, this is the aortic valve and the part on either side of this arrow is the aortic root, the sinuses of valsalva, the ascending aorta and this is the type, that this is the part that dilates in Marfan and connective tissue disorders. It kind of looks pear-shaped at the base and this is the tip of the pear here, and we can measure the size of this very accurately by echocardiogram.
マルファン症候群やロイス・ディーツ症候群、家族性動脈瘤症候群では、大動脈のエコー検査が行われます。この部分が筋肉で、ここが大動脈弁です。この矢印の両側が大動脈基部、バルサルバ洞で、その先が上行大動脈です。マルファン症候群や結合組織疾患では、ここの大動脈基部が拡張します。洋梨のような形をしており、こちら（大動脈基部）が底でこちら（上行大動脈）が先端になります。エコーでは非常に正確に大動脈基部の大きさを測定することができます。
Or on the right panel by a CT scan and again this is a CT scan looking at the proximal aorta. This is a heart muscle down to the lower segment. (Can, Eileen can, are you on? if you can hear me I want to see, yes, I hope you, I hear you, I saw something, can you see my arrow? And can you see the arrow? Okay, perfect.) So that is the heart muscle and this is the aortic root. Again it looks pear-shaped, so this is a typical Marfan aorta, it has a pear-shaped appearance to it, and it's largest in the aortic root, and so we can measure this dimension or compare it to this dimension and these are usually pretty interchangeable.
右の図は、CT画像です。近位大動脈を撮影したものです。ここが心臓下部の筋肉です。（司会者とのやり取り）ここが心筋で、ここが大動脈基部です。やはり洋梨状で、これがマルファン症候群で一般的にみられる大動脈です。大動脈基部が一番太くなっています。CT上の矢印部分の長さを測って、エコーの矢印の長さと比べたりしますが、通常どちらで測っても変わりありません。
Sometimes we don't see the aorta as well because it's shadowing or the pictures just aren't as clear just like sometimes on a television screen or other things. It's just not as clear as this, so we have to use the best modality to see this.
影がかかっていたりして、大動脈がはっきりしないこともあります。この画像のようにはっきりとは見えないことがあるので、最もよく見える方法を使います。
