I Can See Health

Soon, someone realized that Lu Chen was different.

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

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

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

It doesn’t seem like it was done randomly...

This...what's going on?

Jia Bo calmed down, "So what if you have fast hand speed? The final scoring criteria depends on the completeness of the overall surgery."

On the side, Ouyang Ming was also shocked.

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

On the other hand, others are still testing.

But, why did Lu Chen adapt so quickly?

From what Ouyang Ming learned, Jinghua Second Hospital seemed to have only one set of ordinary simulated surgical equipment.

There is no way Lu Chen has ever used such an advanced device!

Everyone outside the judging area, the viewing area and those watching online also had doubts in their hearts.

Cheng Guowen's face was full of doubts.

He knew Lu Chen's electrophysiological level best.

For 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 arose in everyone's hearts at this time!

…

Simulated operating room.

The reason why Lu Chen was able to adapt and adjust right away was entirely due to the help of the system.

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

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

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

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

The first step is to implant the electrodes.

Atrial fibrillation mostly originates from the bilateral pulmonary veins.

Lu Chen placed the electrode on the pulmonary vein.

In the second part, potentials are induced and recorded.

Arrhythmias are induced by a certain amount of excitement and then recorded.

If that area is capable of inducing atrial fibrillation, that's where it originates.

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

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

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

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

Lu Chen used the method of one-hop mapping + excitement sequence estimation to try all the positions.

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

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

There are many ablation methods at present, the common ones include radiofrequency catheter ablation, cryoablation, thermal balloon ablation, microwave ablation, ultrasound 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 requires the surgeon to choose the most appropriate ablation method based on each patient's own conditions.

However, this was 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 had trained in them, but his proficiency was not as high as that of catheter ablation!

He's already in the top ten at the EKG reading stage and now just needs to hold on.

If you forcefully choose a difficult technique, if you make a mistake, your success will be in vain.

"Lu Chen chose the simplest catheter ablation."

Jia Bo felt better when he saw Lu Chen's choice.

He was really afraid that Lu Chen would suddenly show off his difficult skills, and there would really be no one to talk about his regrets.

“Although it’s simple, it’s not necessarily bad.”

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

"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 was not the first time he had performed ablation in a simulated operating room, but it was a very important one.

He took a deep breath and let it out slowly.

His eyes became very firm.

Hundreds of training sessions over the course of a month came to mind.

Just waiting for this moment today!

…

Yu Weiguang, like Lu Chen, got the No. 2 atrial fibrillation ablation.

What he chose was cryoablation, which has been very popular in recent years.

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

However, its shortcomings are also very obvious. This procedure is mainly used for electrical isolation of pulmonary veins and cannot perform linear ablation of 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 slowly become popular in the country.

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

Therefore, he has the courage to use this new type of ablation surgery today.

Jury area.

Jia Bo cast admiring glances at Weiguang.

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

When Ouyang Ming heard this, he smiled slightly and said nothing more.

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

…

Time passes slowly.

Half an hour has passed for the second group of simulated surgeries.

Even though you just stand still, this electrophysiological surgery is also physically strenuous.

Layers of sweat broke out on Lu Chen's forehead.

However, due to his unremitting efforts in ablation, the entire ablation surgery is nearing completion.

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

"Yu Weiguang from your hospital should be the first in the semi-finals. There should be no suspense." Ouyang Ming said with a smile, "He performed perfectly in this simulated surgery."

Hearing this, Jia Bo was extremely pleased.

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

Every time he saw Lu Chen, it reminded him of the interview scene at that time.

However, Lu Chen was not eliminated. Instead, he became 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, have you watched Lu Chen's surgery carefully?"

"Lu Chen?" Jia Bo was stunned, then smiled, "He didn't choose catheter ablation, so why does he still need to see it?"

"Then you have missed a good show." Ouyang Ming said slowly, "There are many ways to use catheter ablation, and there are many categories, such as stromal ablation, rotor ablation, alcohol ablation and focal-driven ablation, and Lu Chen The choice was “2C3L” ablation!”

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

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

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

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 surgery is up to standard." Ouyang Ming.

Jia Bo remained silent.

He knew what Ouyang Ming meant.

According to Lu Chen's results this morning, Lu Chen's probability of advancement is already very high.

…

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

Immediately afterwards, there is the third group of assessments.

The moment Lu Chen walked out of the cath lab, he breathed a sigh of relief.

This month of training will finally bear fruit today.

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