In this next case,

0:01

we're gonna review a patient who has had a successful TAVR in the setting of,

0:05

uh, previous prosthetic valve. So he is had a valve and valve TAVR procedure.

0:10

As we start at the top, you can see the struts of this TAVR device.

0:15

It's a self-expanding device and it's placed within this surgical ring.

0:19

You can see the surgical ring is a complete circle and it's very,

0:23

very densely metallic with a lot of artifact related to that surgical ring.

0:28

You can see that the TAVR device is basically bounded by the outer surgical

0:33

rim ring, and that defines the size of the TAVR device that you can use.

0:39

Other interesting things that TAVR leaflets actually for this particular device

0:43

are s annular. So they're actually above the level of the aortic valve annulus,

0:47

which is just kind of an interesting thing.

0:51

We also see that the coronaries here have really good perfusion.

0:54

You can see nice enhancement of the coronary arteries in a continuous column of

0:57

contrast going into the coronaries. So I just wanna show you that, um,

1:01

valve and valve device on a couple other views. Here's the coronal view.

1:06

Get that away. You can see the,

1:08

the TAVR device sitting inside that surgical valve,

1:12

and somewhere in there are the surgical valve leaflets in post that have been

1:16

pushed to the side. But to be honest,

1:17

it's really hard to see through all of the right artifacts related to the

1:22

TAVR device itself and the stent straps of the tavr.

1:26

And then let me just show you by putting the cross hairs on the middle of the

1:30

device and rotating it to be parallel to the aortic valve plane that's done

1:35

on many other videos.

1:36

You can then see the relationship of the TAVR device itself to that

1:42

prosthetic aortic valve ring. And this is just what it's supposed to look like.

1:46

You should see the device, um,

1:48

snugly located within the prosthetic aortic valve. So this is a,

1:52

a normal post valve and valve CT imaging.
