Shadowing Practice: SVINutes: Super Large Bore Thrombectomy - Learn English Speaking with Video
Creating lesson...
1
Well hi, it's a real treat to be with you here today
2
and talk to you about super large borothrombectomy and why you ought to be including these tools into your arsenal against stroke.
3
I'm Sunil Sheth, I'm an associate professor at UT Health, vascular interventional neurology.
4
So what is super large borothrombectomy?
5
Here we're talking about aspiration using 88 inch diameter catheters or greater.
6
The whole theory behind this approach is that these are catheters that are sized to match your target vessel.
7
So you can see here the sizes of the different vessels
8
that we approach and the most common occlusion that we face in the world of LVO is M1 occlusions.
9
88 catheters will match
10
that outer diameter to the vessel much better than any of the other catheter shapes and sizes that we have.
11
Why is vessel matching so important.
12
First is this concept of flow arrest, stopping enterograde flow and preventing distal embolization.
13
It also, with larger inner diameter, is going to increase your aspiration force.
14
This means you'll have more effective thrombectomy and then with that have less likelihood of distal embolization.
15
So overall that translates to better first-pass reperfusion and that's really the target of every thrombectomy approach is improving that first-pass
16
re-canalization and in in vitro studies large-bore aspiration has shown to do that.
17
So as you put the catheter into the vessel you not only stop intergrade flow substantially
18
but once you turn on aspiration the flow reverses and this is going to prevent dislembolization and also retain the clot
19
in a much better fashion.
20
So with in vitro data we have moved on to in vivo studies
21
and if we look So if you look at how thrombectomy has changed over time, in the bad old days of mercy, well, it didn't really work,
22
but really in the last 10 years we're talking about 2015
23
to 2024 first pass effect has really languished in this 20 to 30 percent range where although we get bigger
24
and bigger aspiration catheters going up to the 070 range the
25
first pass effect has not substantially improved since the early days of stent retrievers back in 2015.
26
So we need a step function we need a real step up in our performance
27
and that's where super large has come in we want to get above at least 60% first pass effect.
28
We are now living in a world where we actually have randomized and prospective trial data showing that we are there.
29
This was one trial that was presented in the summer of 2025 from the perfuse company in the MARS trial.
30
This is their primary efficacy data and as you can see here first pass effect with TIKI 2C 3 or greater.
31
So this is not the usual 2B or greater, but 2C or greater, 61% with their millipede system.
32
And in the M1, again, where you have vessel matching, 77%.
33
These are numbers we have never seen before in rigorously collected prospective clinical trial data.
34
Similarly, from the Route 92 group,
35
the Summit Max trial was a randomized trial comparing their device against a 70 diameter catheter 74 and significantly better reperfusion results.
36
So just to summarize, we are now living in the world of super large-bore thrombectomy.
37
Super large-bore thrombectomy is the first real improvement on first-pass effect
38
we've ever had in the last decade since we've been doing thrombectomy.
39
So it's not a question of should you be doing thrombectomy, it's with super large bore catheters is
40
if you want to provide the best care for your patients you need start including these tools into your arsenal.
41
Thank you and appreciate this opportunity.

Vocabulary and speaking notes for this lesson
This C1 speaking lesson is built on the video “SVINutes: Super Large Bore Thrombectomy”. The speaker keeps coming back to these words: catheter, thrombectomy, pass, vessel, trial. This video has 41 sentences and 603 words to shadow. The speech runs for 3:38. The speaker talks at a natural 166 words per minute, close to everyday conversation. Only 81% of the words are among the 3,000 most common in English, so the vocabulary is demanding.

How to practise with this video
- Listen to the whole video once without speaking and note the words you do not know.
- Start at 0.75× speed, shadow it sentence by sentence, then go back to normal speed once it feels easy.
- Record yourself and compare with the original, paying attention to words like catheter, thrombectomy, aspiration.
What is the Shadowing Technique?
Shadowing is a science-backed language learning technique originally developed for professional interpreter training and popularized by polyglot Dr. Alexander Arguelles. The method is simple but powerful: you listen to native English audio and immediately repeat it out loud — like a shadow following the speaker with just a 1–2 second delay. Unlike passive listening or grammar drills, shadowing forces your brain and mouth muscles to simultaneously process and reproduce real speech patterns. Research shows it significantly improves pronunciation accuracy, intonation, rhythm, connected speech, listening comprehension, and speaking fluency — making it one of the most effective methods for IELTS Speaking preparation and real-world English communication.
