Annular Calcification Case Review

HIDE
PrevNext

0:00

With this next case, we're gonna review a patient who has a lot of annular,

0:04

calcifications and L V O T calcifications of the type that you would certainly

0:09

wanna mention as severe calcifications in your report.

0:12

These are the types of calcifications that put the patients at higher risk for

0:16

annual rupture during the procedure need for pacemaker after the procedure,

0:20

and a higher risk for paravalvular regurgitation because of these large

0:24

calcifications. So on the axial images, what we're gonna see, uh,

0:28

below the level of the coronaries and at the level that UIC valve,

0:31

you can see actually there's quite a lot of calcification of this leaflet here.

0:35

That's probably the left cusp. And then it extends below

0:39

into the annulus and then you can see it also extends all the way over here into

0:42

the mitral and in the region. And then even along this, um,

0:46

anterior leaflet of the mitral valve.

0:48

So I wanna show you that on the N P R images.

0:51

So these are just standard double oblique images.

0:53

You don't need to pay attention to the left upper hand corner image.

0:56

We're just gonna focus on these axial coronal and sagal images and the other

1:01

three windows.

1:02

So if we adjust our planes to get a good look at the aortic valve by centering

1:07

on the aortic valve plane, on the coronal image,

1:10

rotating counterclockwise with our, um, axial plane,

1:15

and then doing the same with the other long axis image here so that we're

1:19

parallel to the aortic valve, then you get a nice look,

1:22

nice short access look of the aortic valve. In this patient.

1:24

You can see the tricuspid valve.

1:27

There's three separate leaflets with a good bit of calcification.

1:29

And this patient, you see this calcification extending inferiorly along the

1:35

annulus and down into the, uh, mitral valve.

1:39

So this is called the aorta mitral continuity or AOR mitral curtain.

1:44

There are different names for it,

1:45

but basically it's just a fibrous connection between the aortic valve and the

1:49

mitral valve. And so when you see a lot of calcification here,

1:53

you wanna mention it, it is considered, um, you know,

1:55

more high risk calcification. Now,

1:58

other spots where you see calcification not in this patient that are important

2:01

to mention would be if you have a large nodular calcifications

2:06

or protruding against the lumen. You can see this is flat,

2:09

but if you had a big nodule sticking outta the lumen,

2:11

you definitely wanna mention that because that can interfere with apposition of

2:15

the stent structs and you can get paravalvular leak.

2:19

And then the other thing is if you have a lot of calcification below the level,

2:22

the non coronary cusp, which is this one right here,

2:25

that points posteriorly towards the inter atrial septum,

2:28

you wanna mention that too because those are also considered higher risk for

2:32

some of these complications that we discussed.
