Chapter 663 Where Did He Come From?

After dinner.

Lu Chen entered the system virtual space.

"Use the valve intervention skill card!"

With a thought, a simulated operating table immediately appeared in the virtual space of the system.

All kinds of equipment and surgical instruments are all matched with "valve intervention" surgery.

After studying for a week.

Lu Chen already has some knowledge about valve interventional surgery.

If the heart is compared to a house, then the valves of the heart are the doors and windows of the house.

Once the valve is broken, that is, the doors and windows of the room are broken, in the long run, the heart function will be damaged, which is heart failure.

The conventional treatment method is surgical thoracotomy, repairing the valve, or replacing the entire valve, which is often called valve replacement surgery.

This kind of major operation is very traumatic to the human body, and requires surgery to open the chest, that is, the operation of extracorporeal circulation.

Valve intervention (TAVR), like coronary intervention, is a minimally invasive treatment of valve intervention through peripheral blood vessels.

It has little harm to the human body, and is especially suitable for some middle-aged and elderly patients who cannot tolerate too much surgery.

……

Now is the time to test your results and improve your skill proficiency!

With the foundation of electrophysiological surgery, Lu Chen can get started faster.

From being clumsy and unfamiliar at the beginning, Lu Chen gradually mastered the essentials of "Valve Intervention".

After staying in the system virtual space for about four hours, Lu Chen felt a little tired, so he withdrew and started to sleep.

Silent all night.

The next day.

Lu Chen ate breakfast and arrived at the catheterization room of the Shanghai Central Hospital early.

Under the leadership of Dai Wansong, the director of the Central Hospital, everyone began to observe the operation.

"The peripheral approach for TAVR includes the femoral artery, carotid artery, and axillary artery, etc. The specific approach to choose depends on the patient's condition and vascular conditions."

Dean Dai Wansong explained and simulated operations for everyone.

"Does any of you know the most commonly used blood vessel route?" Dai Wansong continued.

At this time, a middle-aged doctor said: "Dean, about 90% of clinical TAVR is done through the femoral artery approach."

"That's right." Dai Wansong nodded slightly, "Take the puncture of the femoral artery as an example. Before the puncture, we need to read the CTA images of the peripheral vessels in detail to clarify the location of the deep femoral artery and the superficial femoral artery. The puncture point has no obvious stenosis, plaque or Calcification, etc.”

Because it is a simulated operation, everyone enters in batches and can clearly see the operation area.

"Who can demonstrate the piercing process?" Dai Wansong looked around the crowd.

"Me!" The middle-aged doctor who answered the question just now stood up again.

"Okay, let Dr. Bai Xin demonstrate."

Dean Dai Wansong gave up a position.

Bai Xin put on gloves, held a puncture needle, and began to puncture the femoral artery.

Lu Chen stood aside and observed carefully.

Bai Xin's operation is very professional, and there is no sign of unfamiliarity at all.

"The puncture point is usually within the range of the femoral head, below the inguinal ligament, and at least 10mm above the bifurcation of the femoral artery. The puncture methods include micropuncture, contralateral contrast puncture, ultrasound-guided puncture, and pigtail puncture..."

Bai Xin's explanation is also very clear.

However, Lu Chen knew very well that the puncture of these peripheral blood vessels was not the point.

The most difficult technique of "valve intervention" is the guide wire transvalvular technique, track establishment and balloon pre-dilation technique.

Sure enough, after the femoral artery puncture, Dean Dai Wansong continued to ask: "Is there anyone who can demonstrate the transmembrane operation of the guide wire?"

As soon as the voice fell, no one responded.

Dr. Bai Xin, who was more active just now, also has a very hesitant expression at this time.

"Aren't you willing to give it a try?" Dai Wansong asked again.

When Lu Chen was about to step forward, Bai Xin moved.

He stepped forward, "Dean Dai, let me try again."

"Okay." Dai Wansong nodded with a smile, "Don't be afraid of making mistakes. This is the first attempt. Once you have started, you will improve slowly."

Bai Xin took a deep breath, and then walked onto the simulation console.

With the guide wire in his hand, he began to push it in.

"When the guide wire crosses the valve, it should be operated gently to avoid the guide wire from entering the coronary artery by mistake. Grasp the opening of the systolic aortic valve and push the guide wire across the valve. For severe stenosis or misalignment of the valve leaflets, a super-slip guide can be used. Silk."

While talking, Bai Xin inserted the guide wire.

The movements are not as skillful as before, but even through bumps and bumps, the guide wire was successfully passed through the valve.

If it is the first time for Baixin to do valve intervention, it will be very difficult if the guide wire can pass through the valve!
The onlookers were amazed.

"I heard that Bai Xin is Dean Dai's student, it seems that he got the true biography!"

"I'm sure Bai Xin has done this type of surgery before, otherwise he wouldn't be so proficient."

"If you have done it, you should come to the study class? Doesn't this count for the quota?"

"Continue to study, I have done it before, but it's just an assistant..."

While everyone was discussing, a student suddenly asked: "Dr. Bai, if you use a super-smooth guide wire, you still can't pass?"

"This..." Bai Xin suddenly froze.

He has indeed undergone valvular interventional operations, but he is only the first assistant, and he has not encountered such a situation.

The others also stared at Bai Xin, expecting an answer from him.

However, everyone was disappointed.

Bai Xin thought for a while, then shook his head, "I haven't encountered such a situation yet, so..."

There was also a touch of disappointment in Dai Wansong's eyes, and he was about to remind everyone.

At this moment, a calm voice came from among the students.

"If none of the above methods guide the wire to pass through the stenotic valve in a forward direction, it may be considered to puncture the interatrial septum and reversely cross the aortic valve to establish a track."

It was Lu Chen who said this, and he took a step forward.

All the students followed the sound.

In the eyes of everyone, why is this student so young?
Dai Wansong showed a look of surprise on his face, "Have you met before?"

Lu Chen shook his head, "No, I've read the corresponding operating materials, which seem to have mentioned it."

Lu Chen has never encountered it in real life, but has seen it in the virtual space of the system.

Is he right?
Everyone was puzzled and looked at Dean Dai Wansong one after another.

Dean Dai Wansong nodded slowly, "That's right, this student is right! At this time, we can consider puncturing the interatrial septum and building a track across the aortic valve in reverse."

It turned out to be right!
Everyone was shocked, and looked at Lu Chen with astonishment.

Where did this guy come from?
"What's your name, which hospital is it from?"

Dai Wansong asked everyone's aspirations.

Lu Chen smiled slightly, looked at everyone, and said slowly: "The First Affiliated Hospital of Shanghai University, Lu Chen is a PhD student in the Department of Cardiology."

Lu Chen?

Everyone thinks this name sounds familiar!
Among the students, someone suddenly exclaimed.

"He's that Lu Chen from the Heart Failure Conference?!"

　Because the school I was in charge of checking the nucleic acid was all negative, so I ended the quarantine early this afternoon...

　　Such a short quarantine period. (two days)
