   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 of   , 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 the last week of study.

  Lu Chen already knew something about valve interventional surgery.

   If the heart is likened 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. If things go on like this, the heart function will be completely damaged, that is, heart failure.

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

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

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

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

  …

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

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

   From awkward and unfamiliar at the beginning, Lu Chen gradually mastered the essentials of "valve intervention".

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

   was speechless all night.

   The next day.

  Lu Chen had breakfast and came to the catheterization room of the Magic Capital Central Hospital early.

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

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

   Dean Dai Wansong explained and simulated the operation for everyone.

   "Who of you know the most common vascular path?" Dai Wansong continued.

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

"That's right." Dai Wansong nodded slightly, "Take femoral artery puncture as an example. Before puncture, we should read the CTA images of peripheral blood vessels in detail, and identify the bifurcation of the deep femoral artery and superficial femoral artery. There is no obvious stenosis, plaque or puncture at the puncture point. calcification, etc."

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

   "Can anyone demonstrate the puncture process?" Dai Wansong looked around the crowd.

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

   "Okay, then let's demonstrate by Dr. Bai Xin."

   Dean Dai Wansong gave up a position.

  Bo Xin put on gloves, held the puncture needle, and started femoral artery puncture.

  Lu Chen stood aside and observed it carefully.

  Bo Xin's operation is very professional, and there is no strange appearance at all.

   "The puncture point is usually within 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, pigtail canal puncture..."

   Bo 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 techniques for "valvular intervention" are the techniques of guide wire crossing the valve, orbital establishment and balloon pre-dilation.

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

   As soon as the voice fell, no one responded.

   Doctor Bai Xin, who was more active just now, was also very hesitant 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, it's your first attempt. Once you get started, you can slowly improve it later."

  Bo Xin took a deep breath, and then stepped onto the simulation console.

   He held the guide wire in his hand and began to push it in.

"When the guide wire crosses the valve, the operation should be gentle, to avoid the guide wire entering the coronary artery by mistake, and to seize the opportunity of opening the aortic valve during systole to push the cross valve guide wire homeopathically. For severely stenotic valve orifice or valve leaflet abutment misalignment, super-sliding guide wire can be used. Silk."

  Bo Xin said as he fed the guide wire.

The    movement is not as skilled as before, but in the bumping, the guide wire was successfully passed through the valve.

   If it is the first time that Bo Xin has performed valve intervention and can let the guide wire pass through the valve, it will be very difficult!

  The people watching were amazed.

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

   "I'm sure that Bai Xin has done this kind of surgery before, otherwise it would be impossible to be so skilled."

   "Have you done it and come to the study class? Does this not count for a place?"

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

   Just as everyone was talking, a student suddenly asked, "Doctor Bai, if I use the ultra-smooth guide wire, will I still not be able to pass it?"

   "This..." Bai Xin was suddenly stunned.

   He did have valve intervention surgery, but he was only the first assistant, and he had never encountered such a situation.

  Others are also staring at Bo Xin, expecting an answer from his mouth.

   However, everyone was disappointed.

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

   Dai Wansong also had a hint of disappointment in his eyes, he was just about to remind everyone.

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

   "If the guide wire cannot pass through the stenotic valve in the forward direction by the above methods, puncture of the atrial septum can be considered to establish a track across the aortic valve in the reverse direction."

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

   All the students looked at the sound.

   In the eyes of everyone, why is this student so young?

  Dai Wansong had a surprised look on his face, "Have you met before?"

  Lu Chen shook his head, "No, I have read the corresponding operation materials, and it seems to have mentioned it."

  Lu Chen has never met him in reality, but he has seen him in the system virtual space.

   Was he right?

   Everyone had some doubts in their hearts, and all looked at Dean Dai Wansong.

   Dean Dai Wansong nodded slowly, "Yes, this student is right! At this time, we can consider puncturing the atrial septum and establishing a track across the aortic valve in reverse."

   is actually right!

   Everyone was shocked, and looked at Lu Chen with a look of surprise.

   Where did this person come from?

   "What's your name and which hospital are you from?"

   Dai Wansong asked everyone what they wanted to say.

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

  Lu Chen?

   Everyone thinks this name sounds familiar!

   Among the students, someone suddenly exclaimed.

   "Is he the Lu Chen from the Heart Failure Conference?!"

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

   What a short quarantine time. (two days)
