Chapter 353: End of Assessment

Soon, someone realized that Lu Chen was different.

His speed of operation was obviously much faster than other contestants!

"This... Is this kid messing around?"

Jia Bo frowned, staring at Lu Chen's operation interface.

It doesn't seem to be messing around...

This... What's wrong?

Jia Bo calmed down, "What's wrong with fast hand speed? The final scoring criteria will be based on the completeness of the overall operation."

On the side, Ouyang Ming was also shocked.

The catheter and sheath in Lu Chen's hand were very "obedient" and soon reached the designated heart part.

On the other hand, others were still trying.

But how did Lu Chen adapt so quickly?

According to Ouyang Ming's understanding, Jinghua Second Hospital seemed to have only one set of ordinary simulated surgery equipment.

Lu Chen couldn't have used such advanced equipment!

Apart from the judges, the people in the viewing area and those watching online also had doubts in their hearts.

Cheng Guowen was full of doubts.

He knew Lu Chen's electrophysiological level best.

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

How could he adapt to the advanced equipment in the first place?

A huge question mark appeared in everyone's mind at this time!

...

Simulated operating room.

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

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

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

The operation of the catheter and sheath is just the beginning.

Next, Lu Chen needs to induce and locate arrhythmia.

The first step is to implant electrodes.

Most atrial fibrillation originates from the bilateral pulmonary veins.

Lu Chen placed the electrodes in the pulmonary veins.

The second step is to induce and record the potential.

Arrhythmia is induced by a certain excitement, and then recorded.

If the area can induce atrial fibrillation, it is the origin location.

However, the origin of atrial fibrillation usually has other locations.

Therefore, if only the pulmonary veins are ablated, the patient's chance of atrial fibrillation recurrence after surgery will be very high!

Now, what Lu Chen has to do is to locate as many positions as possible.

Non-pulmonary vein triggering foci are commonly found in special anatomical structures in the atrium, such as the superior vena cava, Marshall ligament, terminal ridge, coronary sinus, left atrial appendage, right atrial appendage, and left superior chamber.

Lu Chen used the method of one-beat mapping + excitation sequence inference to try all the positions.

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

The last step, and the most important step, is ablation!

There are many methods of ablation at present, the most common ones are radiofrequency catheter ablation, cryoablation, thermal balloon ablation, microwave ablation, ultrasonic balloon ablation, and laser visualization balloon ablation.

No matter which method is used, the most basic principle is that the effect should be good, the recurrence rate should be low, and the complications should be few.

This is why the surgeon needs to choose the most appropriate ablation method according to the conditions of each patient.

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

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

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

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

If he forcibly chooses a difficult procedure, once he makes a mistake, then all his efforts will fail.

"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, and then he would really have no one to talk to about his regret.

"Although it is simple, it may not be bad."

Ouyang Ming smiled, "Although the other methods are simpler, it is difficult to avoid missing some induced areas. The catheter ablation procedure takes a long time, but it can cleanly ablate most areas."

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

Lu Chen has prepared the ablation tools.

This is not the first time he has performed an ablation operation in a simulated operating room, but it is a very important one.

He took a deep breath and then slowly exhaled.

His eyes became very firm.

His mind flashed back to the hundreds of training sessions he had done in the past month.

Just to wait for this moment today!

…

Yu Weiguang, like Lu Chen, drew the second atrial fibrillation ablation.

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

Cryoballoon ablation surgery has relatively minor damage to the endothelium, can activate platelets less, and has the advantages of lower risk of thromboembolism.

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

In other words, the recurrence rate of cryoablation may be higher than that of conventional catheter ablation!

However, this new technology has gradually become popular in China.

Yu Weiguang has also been exposed to many cryoablation surgeries. As the first or second assistant, he participated in the entire operation.

So, he also had the courage to bring out this new type of ablation surgery today.

Judges area.

Jia Bo cast an admiring look at Wei Guang.

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

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

The current situation has basically been determined. It depends on the completion of the surgery of each participant.

...

Time passed slowly.

Half an hour has passed since the second group of simulated surgery.

Although it is just standing still, this electrophysiological surgery is also a physical job.

Lu Chen's forehead was sweating.

However, with his unremitting efforts to ablate, the entire ablation surgery is nearing its end.

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

"Yu Wei Guang from your hospital, the first place in the semi-finals, should be no suspense." Ouyang Ming smiled, "This time, his performance in the simulated surgery was perfect."

Hearing this, Jia Bo was very happy.

These two days, he was almost annoyed by this Lu Chen.

Every time he saw Lu Chen, he would think of the interview scene at that time.

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

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

"But..."

But at this moment, Ouyang Ming changed the subject.

"Professor Jia, did you watch Lu Chen's operation carefully?"

"Lu Chen?" Jia Bo was stunned, and then smiled, "Didn't he choose catheter ablation? Do you still need to watch it?"

"Then you missed a good show." Ouyang Ming said slowly, "There are many ways in catheter ablation, and there are many categories, such as matrix ablation, rotor ablation, alcohol ablation and focal drive ablation, and Lu Chen chose "2C3L" ablation!"

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

"You should have heard that at the electrophysiology conference last month, Director Liu of Kyoto Medical University Anzhen Hospital first proposed the 2C3L ablation strategy." Ouyang Ming said.

"He... he actually knew this ablation strategy?" Jia Bo swallowed his saliva, his eyes were astonished.

He himself only had a rough impression, UU reading www.uukanshu.net Lu Chen actually started the simulated surgery directly?

"Although his technique is still a bit rough, the overall completion of the operation has also met the standard." Ouyang Ming.

Jia Bo remained silent.

He knew what Ouyang Ming meant.

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

...

At this time, the second group of assessments was completed!

Next, it was the third group of assessments.

When Lu Chen walked out of the catheterization room, he was completely relieved.

This month's training will finally bear fruit today.

An hour later, the third group of assessments finally ended.
