This next video,

I'm gonna go through a case which is an example of device migration.
0:06
In this particular patient while placing the valve,
0:09
they attempted to do a dilation because there was a, a part,
0:13
it was a self-expanding valve and there was a piece of the valve that didn't
0:15
completely expand. And so they went in with a balloon and tried to dilate it in.
0:19
Somehow when they put the balloon in,
0:21
that actually resulted in the valve moving out of position and and migrating.
0:25
What they had to do is then go up with the catheters and retrieve the valve,
0:29
and then they pulled the valve actually closer into the ace aorta into,
0:33
you know what they considered a safe spot below the level of the origins of the
0:38
arch vessels.
0:39
So we can see here as we head down here are the arch vessels in this patient,
0:44
and then here we get into this TAVR device way up high.
0:49
And this is the migrated device, which has been moved into a safe position.
0:54
And then here they went ahead and put in a second valve because obviously the
0:58
first valve wasn't successful,
0:59
so they went ahead again and put in a second valve.
1:02
Now this is not a cardiac aid study, that's why it's a little bit blurry.
1:05
I thought it was a really good example of what can happen with one of these
1:09
valve migrations. I just wanna show you what this looks like on coronal images.
1:14
Here you see on coronal you can see device number one way up
1:19
high.
1:19
So that was the first one that migrated and then was repositioned into a safe
1:24
position of mouse and not how, how sure,
1:26
how far distillate got before the repositioning. But um, nonetheless,
1:31
they put it in the ascending aorta. And then here's the second device,
1:34
which is put in the appropriate location. So not something you see every day.
1:39
This is not a very common complication of tavr, but you know,
1:42
certainly can happen. Very rarely.
