Thoracic Aortic Syndromes w/ Paul Sheats NRP, FP-C

You want to go through the anatomy first?

Yeah.

So the anatomy of it is...

I'll bring up the...

For people that are watching, or excuse me, that are listening, you might want to come back and also...

What do you call it? Watch it at some point because we'll have a visual.

Thank you to Wikipedia for providing a great visual.

Yeah, there we go.

Great.

So there we got it.

As we can see, we got our ascending aorta.

The root comes right off that left ventricle.

And it's going to ascend upwards.

And it takes a really, really abrupt turn.

You see that curvature right there.

It's very abrupt.

And then it goes down to our descending aorta.

And something really important to focus on this is that arch right there.

That arch is so sharp and so quick.

So you think about a... hose that you're hooking up to a pump the pump being your heart the hose being the aorta and what happens when you kink a hose very very sharply you're going to get a pressure build up and if you have weak spots in that hose and that's a prime area for weak spots just because the pressure is so high coming out of that left ventricle and the anatomy itself is at that curvature where you know you're going to have weak spots especially in that that outer area that that branches off to the uh in dominant, the right subclavian and the left subclavian.

So just structurally as it is, that aortic arch and the ascending aorta is just a prime area for weakness, right? Just based off the fact that it has a large amount of pressure coming off it from the left ventricle.

And it's just anatomically, you know, as humans, we could have been built just a scoach better, maybe make that angle on your aorta a little bit broader.

So it's a little bit of a anatomical setback that we have as humans is that we got a a hose that's under high pressure and it's making a really, really, really sharp turn.

So let's start.

We can see the, we've got the root of the aorta comes off the heart.
