Chapter 358 The end of the assessment
Soon, someone realized that Lu Chen was different.

The speed of his hands is obviously much faster than other contestants!

"This... this kid can't be messing around, right?"

Jia Bo frowned, and he stared at Lu Chen's operation interface.

It's not like messing around...

What... what's wrong?
Jia Bo held his breath, and said to himself, "So what about fast hands? The final scoring standard depends on the completeness of the overall operation."

On the side, Ouyang Ming was equally astonished.

The catheter and sheath in Lu Chen's hands were very "obedient", and they quickly reached the designated heart site.

On the other hand, others are still trying to find out.

But, how did Lu Chen get used to it so quickly?

According to Ou Yangming's knowledge, Jinghua Second Hospital seems to have only one set of ordinary simulated surgical devices.

It is impossible for Lu Chen to use such an advanced device before!

In addition to everyone in the judges' area, doubts arose in the hearts of those in the spectator area and online.

Cheng Guowen was full of doubts.

He is the clearest about Lu Chen's electrophysiological level.

During this month, Lu Chen has been by his side.

How could he have adapted to the advanced equipment in the first place?

At this moment, a huge question mark arose in everyone's heart!

……

simulated operating room.

The reason why Lu Chen was able to adapt and adjust in the first place was entirely thanks to the help of the system.

No matter how much this advanced device simulates reality, can the virtual space of his system be more realistic?

However, although he adjusted quickly, he did not dare to relax at all.

Catheter and sheath manipulation is just the beginning.

Next, Lu Chen needs to induce and locate the arrhythmia.

The first step is to implant electrodes.

Atrial fibrillation mostly arises from the bilateral pulmonary veins.

Lu Chen placed the electrodes on the pulmonary veins.

In the second part, potentials are evoked and recorded.

Arrhythmias are induced by certain agitation and then recorded.

If that area is capable of inducing atrial fibrillation, that is the site of origin.

However, there are usually other locations where AF originates.

Therefore, if only the pulmonary veins are ablated, the chances of postoperative atrial fibrillation recurrence will be very high!
Now, what Lu Chen has to do is to locate as many positions as possible.

Instead of pulmonary vein triggers, it is common in special anatomical structures in the atrium, such as the superior vena cava, Marshall's ligament, ridge border, coronary sinus, left atrial appendage, right atrial appendage, and left superior cavity.

Lu Chen used the method of one-jump mapping + excitement order guessing to try all the positions.

Among them, the superior vena cava, Marshall ligament, left atrial appendage, right atrial appendage and other regions can induce atrial fibrillation.

The last step, and the most important step, is to dissolve!

At present, there are many ablation methods, common ones include radiofrequency catheter ablation, cryoablation, thermal balloon ablation, microwave ablation, ultrasonic balloon ablation, and laser visualization balloon ablation.

No matter which method, the most basic principle is that the effect is better, the recurrence rate is low, and the complications are few.

This requires the surgeon to choose the most suitable ablation method according to each patient's own conditions.

However, this is currently a simulation of surgery, and Lu Chen directly chose radiofrequency catheter ablation.

This is the most common and conventional method of ablation, and it is also the one that Lu Chen is best at.

As for the other types, Lu Chen has trained, but the proficiency is not as high as that of catheter ablation!

He has entered the top ten in the stage of ECG interpretation, and now he just needs to stabilize.

If you forcibly choose a difficult technique, once you make a mistake, it will be a waste of time.

"Lu Chen chose the simplest catheter ablation."

Seeing Lu Chen's choice, Jia Bo felt better.

He was really afraid that Lu Chen would suddenly show off a difficult operation, so there was really no one to talk about his regrets.

"Simple, but not necessarily bad."

Ouyang Ming smiled, "Other methods, although the operation is simpler, it is difficult to avoid missing some induced areas. Catheter ablation takes a long time, but most areas can be ablated very cleanly."

"As long as he can do it well, it may be more useful than those ostentatious ablation surgeries."

Lu Chen has already prepared the tools for ablation.

It's not the first time he's performed an ablation in a simulated operating room, but it's an important one.

He took a deep breath and let it out slowly.

His eyes became very firm.

Hundreds of times of training in this month came to mind.

Just waiting for this moment today!
……

Yu Weiguang, like Lu Chen, won the second lottery for atrial fibrillation ablation.

He chose cryoablation, which has been very popular in recent years.

Cryoballoon ablation surgery has relatively slight damage to the endothelium, less activation of platelets, and a lower risk of thromboembolism.

However, its disadvantages are also very obvious. This procedure is mainly used for electrical isolation of pulmonary veins, and linear ablation of special parts such as the top of the left atrium cannot be performed.

In other words, the recurrence rate of cryoablation may be higher than that of conventional catheter ablation!
However, this new type of technology has gradually become popular in China.

Yu Weiguang has also been in contact with many cases of cryoablation surgery. As the first or second assistant, he participated in the whole operation process.

Therefore, he also has the guts to take out this new type of ablation surgery today.

Judges area.

Jia Bo gave Wei Guang admiring eyes.

"Compared to Lu Chen, I prefer Yu Weiguang's choice. People always need to improve, and they must keep pace with the times!"

Hearing this, Ouyang Ming smiled slightly, but didn't say much.

The current situation has basically been settled, and it depends on the completion of each participant's surgery.

……

Time passed slowly.

Half an hour had passed for the second group of simulated operations.

Regardless of just standing still, this electrophysiological surgery is also a physical effort.

Lu Chen's forehead was covered with thin layers of sweat.

However, with his unremitting efforts to ablate, the entire ablation operation is nearing completion.

"Professor Ouyang, what do you think of this group?" Jia Bo looked at Ouyang Ming at the side.

"Yu Weiguang from your hospital, No. 1 in the rematch, there shouldn't be any suspense." Ouyang Ming said with a smile, "This time he performed the simulated surgery perfectly."

Hearing this, Jia Bo benefited greatly.

In the past two days, he was almost annoyed by this Lu Chen.

Every time he sees Lu Chen, it reminds him of the interview scene.

However, Lu Chen was not eliminated. Instead, he became more and more courageous and entered the semi-finals.

Yu Weiguang's outstanding performance made the melancholy in his heart lessen a lot.

"but……"

But at this moment, Ouyang Ming changed the subject.

"Professor Jia, have you watched Lu Chen's operation carefully?"

"Lu Chen?" Jia Bo was taken aback for a moment, then smiled, "Didn't he choose catheter ablation, why do we still need to look at it?"

"Then you missed a good show." Ouyang Ming said slowly, "There are also many ways in catheter ablation, and there are many categories, such as matrix ablation, rotor ablation, alcohol ablation, and focal-driven ablation, while Lu Chen The choice is "2C3L" ablation!"

"2C3L ablation?" Jia Bo felt that this ranking was somewhat familiar.

"You should have heard that at the electrophysiological conference last month, Dean Liu of Anzhen Hospital Affiliated to Kyoto Medical University proposed the 2C3L ablation strategy for the first time." Ouyang Ming said.

"He... he actually knows this kind of ablation strategy?" Jia Bo swallowed, his eyes startled.

He himself only had a rough impression that Lu Chen actually started the simulated surgery directly?

"Although his technique is still a bit rough, the completion of the overall operation has reached the standard." Ou Yangming.

Jia Bo was silent.

He knew what Ouyang Ming meant.

According to Lu Chen's results in the morning, the probability of Lu Chen advancing is already very high.

……

At this point, the second set of assessments is complete!
Then came the third set of assessments.

When Lu Chen walked out of the catheterization room, he also breathed a sigh of relief.

This month's training will finally bear fruit today.

An hour later, the assessment of the third group was finally over.
