   Chapter 358 The end of the assessment

   Soon, someone realized that Lu Chen was different.

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

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

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

   doesn't seem to be messing around...

  This...what's the matter?

  Jia Bo calmed down and said, "What about fast hands? The final grading standard depends on the completeness of the overall operation."

Beside   , Ou Yangming was equally astonished.

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

   On the other hand, other people are still testing.

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

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

   It is impossible for Lu Chen to have used such an advanced device!

   In addition to everyone in the judges area, those who watched the game and watched online also raised doubts in their hearts.

   Cheng Guowen's face was full of doubts.

   Lu Chen's electrophysiological level, he is the clearest.

   This month, Lu Chen has been by his side.

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

   In the hearts of everyone, a huge question mark has arisen at this time!

  …

  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 this advanced device simulates reality, can there be a more realistic virtual space of his system?

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

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

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

  The first step is to implant electrodes.

   Atrial fibrillation mostly originates from bilateral pulmonary veins.

  Lu Chen placed the electrodes in the pulmonary veins.

  The second part, evoking and recording potentials.

  Arrhythmia is induced by a certain excitation and then recorded.

   If this area can induce atrial fibrillation, that is the origin.

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

   Therefore, if only the pulmonary veins are ablated, the probability of postoperative atrial fibrillation recurrence will be very high!

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

   Rather than pulmonary vein trigger foci, it is commonly found in special anatomical structures in the atrium such as the superior vena cava, Marshall's ligament, bordering crest, coronary sinus, left atrial appendage, right atrial appendage, and left superior chamber.

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

   Among them, the superior vena cava, Marshall's 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!

  There are many ablation methods at present, such as radiofrequency catheter ablation, cryoablation, thermal balloon ablation, microwave ablation, ultrasound 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 is where the surgeon needs to choose the most appropriate 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 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 catheter ablation!

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

   If you forcibly choose a highly difficult spell, once you make a mistake, you will fall short.

   "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 manipulations, and he really couldn't find anyone to express his regrets.

   "It's simple, but 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 dazzling ablation surgeries."

  Lu Chen has prepared the ablation tool.

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

   He took a deep breath and let it out slowly.

   His eyes became very firm.

   comes to mind, hundreds of training sessions this month.

   is just waiting for this moment today!

  …

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

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

   Cryoballoon ablation has the advantages of relatively minor endothelial damage, less activation of platelets, and lower risk of thromboembolism.

   However, its shortcomings 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.

   That is to say, 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 a first or second assistant, he participated in the whole operation process.

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

   Judges area.

  Jia Bo gave Weiguang admiration.

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

  Ou Yangming smiled and said nothing.

  The current situation has basically been settled, it depends on the completion of the operation of each participant.

  …

   Time passed slowly.

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

   Don't look at just standing still, this electrophysiological surgery is also a physical activity.

   Lu Chen's forehead was dripping with layers of fine sweat.

   However, with his unremitting efforts to ablate, the entire ablation operation has come to an end.

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

   "Yu Weiguang from your hospital, the first place in the rematch, shouldn't have any suspense." Ouyang Ming smiled, "This time the simulated surgery, he performed perfectly."

   Hearing this, Jia Bo was very helpful.

   For 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 at that time.

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

   Yu Weiguang's excellent performance made the melancholy in his heart a lot lighter.

"but……"

   But at this moment, Ou Yangming's words changed.

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

   "Lu Chen?" Jia Bo was stunned for a moment, then smiled, "He didn't choose catheter ablation, do we still need to see it?"

"Then you missed a good show." Ou Yangming said slowly, "There are also many doorways 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 Electrophysiology Conference last month, President Liu of Anzhen Hospital Affiliated to Kyoto Medical University proposed the 2C3L ablation strategy for the first time." Ouyang Ming said.

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

   He only had a general impression, Lu Chen actually started the simulated surgery?

   "Although his technique is still a bit rough, the completion of the overall operation is also up to standard." Ou Yangming.

   Jia Bo was silent.

  Ou Yangming means, he knows.

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

  …

   At this point, the second set of assessments is completed!

   Immediately after, is the third group of assessments.

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

   This month of training will finally bear fruit today.

   After an hour, the assessment of the third group finally ended.
