In this case,
0:02
we're gonna review that same bicuspid valve case that we saw before with two
0:07
separate sinuses. And now look at the post TTR results.
0:10
So this patient got a self-expanding aortic valve and you can see those
0:15
really chunky calcifications that we visualized on the, uh,
0:19
previous exam, the pre TAVR exam.
0:22
And they're pressing up against the edge of this TAVR device.
0:26
And so I just want to show you how that looks on the short axis images.
0:30
So again, we're gonna go for the coronal image,
0:34
drop our cross hairs at the level of the valve rotate,
0:37
so we're parallel more or less to the valve plane.
0:41
And then do the same for the other long axis image.
0:45
And that allows us to get this nice short axis view
0:49
through the aortic root and the annulus region.
0:53
And you can see here's the top of the TAVR device.
0:57
And as I scroll downward first you can see that the coronaries are open
1:02
and they're well perfused. And then as we go down inferiorly,
1:06
let's take these distance measurements away.
1:09
You can see this big hunk of calcification,
1:12
which is displacing the edges of the TAVR device towards the center.
1:17
So this is resulting in incomplete opposition of
1:22
the TAVR struts to the aortic annulus. Um,
1:25
and you can see there's actually a little bit of a gap underneath of this. Now,
1:29
whether or not this causes actually results in paravalvular leak is something
1:34
that we will figure out based on echocardiography that does a really good job of
1:38
seeing whether there's any retrograde flow on their Doppler assessment.
1:44
It does look like this patient would probably be at high risk for some degree of
1:48
paravalvular leak. You know,
1:50
usually you can find little areas like this where there's, um,
1:53
a gap around the device at the level of the anulus that's concerning.
1:58
So in this particular case, you can see that there's this big hunk of calcium.
2:02
There's this gap down here.
2:05
So it depends a little bit on where that covered portion of the device is gonna
2:08
end up. But certainly you would wonder about this patient having, um,
2:12
paravalvular leak.
2:14
So this is one of the reasons why when we look at patients with bicuspid valves,
2:19
we often find that they have a higher risk of getting para regurgitation.
