  Chapter 924 Valve Regurgitation

  kebed spent a week in the Fifth Academy of the Magic City.

   A week later.

   The final evaluation of the tricuspid valve repair system came as scheduled.

   This time the operation was silent and very low-key.

   Only a few people in the Cardiology Department of the Fifth Hospital of the Magic City knew about the arrangement of this operation.

  Lu Chen, Kebed, Gu Xinyue and Jin Miao all came to the Cardiology Interventional Catheterization Room.

  The tricuspid valve repair system after many improvements has been shown in the eyes of everyone.

  This valve repair device is small in size, but its internal structure is extremely precise.

   As long as the No. 5 Hospital of the Magic Capital passes the test of this evaluation operation, it means the birth of the first "tricuspid valve repair system" in China!

  …

   Catheter room.

  Except Lu Chen, everyone had a solemn expression.

   For him, failure is just another time.

   There are countless ideas in his mind, this time he failed, and the next time.

   But for others, this time is missed, and the next time will not know when.

   The most important thing is, can I hug Lu Chen's thigh, that's all.

   "The surgery begins!"

   Following Lu Chen's order, Jin Miao and Gu Xinyue took the catheter of the "Tricuspid Valve Repair System" and began to puncture the blood vessel and enter the patient's body.

   The device for tricuspid valve repair mainly includes a main body and a plurality of coupling elements.

  The main body is a substantially annular D shape with an eccentric opening.

  The mitral valve facing the left atrium during systole covers substantially the entire part of its posterior leaflet, thereby preventing and reducing tricuspid regurgitation, which is also the key point of the entire tricuspid valve repair device!

  Jin Miao successfully delivered the tricuspid valve repair system to the heart valve.

   To avoid the supra-tricuspid device attaching to the annulus, causing the chordae tendineae to bear the load.

  Lu Chen attached the supra-tricuspid device to the functional leaflets, and by attaching to the valve leaflets, engaged the many chordae tendineae that were not torn to support the flail segment.

   In addition, there is another difficulty in the operation!

  The human heart is always beating.

  Traditional devices, during the beating of the heart, may repeatedly touch between the device above the tricuspid valve and the posterior leaflet, causing cumulative damage to the valve leaflet tissue.

  Lu Chen modified the traditional method to keep the tricuspid valve device attached to the posterior leaflet.

   Let them move together without collision events.

   "Lu, your idea is so cool!" Kebed looked at the device in admiration.

Lu Chen smiled and explained while directing the operation: "The supra-tricuspid valve device is made of flexible material, which slowly hardens after the device is implanted, which advantageously enables the supra-tricuspid valve device to adopt the anatomy of the leaflet tissue. shape, keeping the functional chordae tendineae at their natural length, thus maintaining an even load distribution between them, while absorbing the systolic thrust of left ventricular pressure."

   "Awesome! It's amazing!" Kebed gave a thumbs up.

   The whole operation has been done so far, and I have not encountered any problems for the time being.

  Puncture, catheter guide wire entry, and repair system delivery were all very smooth.

   But Lu Chen's thinking was always tense, and he didn't dare to relax in the slightest.

  Because the real stumbling block is still behind, the biggest problem in valve repair is the amount of valve regurgitation!

  How to judge regurgitation?

   After the operation is completed, you need to listen to the cardiac ultrasound instrument to measure the size of the regurgitation, as well as the valve area and the perioral velocity.

   Once the blood flow is too large, the whole operation will be a complete failure.

   "Lu, I would like to know how you can reduce the valve regurgitation problem after the repair?" Kebed wondered.

   This conundrum is also plaguing Mayo's internal patching system.

Lu Chen picked up the icon of the tricuspid valve repair system and explained: "Look at the part where this extension adjoins the posterior part. When the device was implanted, I made it overlap the posterior part of the anterior leaflet. Through this special The overlapping area can effectively reduce tricuspid regurgitation."

   "Ah? You can still do this!"

  Kebed was stunned, and began to think about how the entire valve device works.

  The valve repair system he saw today was the first of its kind in the world!

  …

   However, this is just a simulated operation after all.

   Twenty minutes later.

   With the assistance of Gu Xinyue, Jin Miao completed the entire tricuspid valve repair operation.

   At this time, he didn't dare to let out the air, and his eyes were fixed on the valve image on the screen.

  The operation was successfully completed, but it does not mean the success of the operation.

   "Bring me the ultrasound machine!"

   The nurse on the counter quickly brought the cardiac ultrasound machine over.

  Lu Chen took the probe and started the ultrasound examination.

   "Valve position is good!"

   "Valve area is good!"

   "Valve flow is good!"

   The last and most important indicator is the degree of valve regurgitation.

   Everyone was staring at Lu Chen, wanting to know the final result as soon as possible.

   At this time, Lu Chen was also attentive, holding the ultrasound probe in his hand to check the size of valve regurgitation on the ultrasound screen.

   Finally, he saw the final image.

   Gently put down the ultrasound machine, Lu Chen slowly raised his head and smiled at the crowd: "Valveal regurgitation is very rare!"

The voice of    just fell.

   In the entire catheterization room, everyone breathed a sigh of relief, and turned to show joy.

  Jin Miao and Gu Xinyue raised their brows with joy, their hands trembling slightly with excitement.

   The entire simulated surgical operation was completed by the two of them.

   "We... succeeded!" Gu Xinyue said excitedly.

  Jin Miao nodded suddenly and said in agreement, "Yes, it was successful, I did it!"

   "I... became an assistant!" Gu Xinyue smiled.

  Lu Chen stood aside and poured cold water on the two of them at the right time.

   "This is a simulated surgery. When it is really successful for clinical patients, be happy."

   "Hehe." Jin Miao heard the words and restrained her smile, but she still looked overjoyed.

   At this time, Professor Kebed was surrounding the tricuspid valve repair system, constantly observing.

   "Lu, can you lend us this Mayo?" Kebed suddenly raised his head and said, "We'll pay for it!"

  Lu Chen smiled and shook his head, "I'm afraid not. This system is a collaboration between our Fifth Academy of the Magic Capital and a company in the Magic Capital. The purpose is to develop China's first tricuspid valve repair system, and it must not be sold."

   "What a pity." Kebed shook his head.

  Lu Chen said with a smile, "Professor Kebed, Mayo's current patching system is okay. With a little modification, it will definitely be better."

  Kebed spread his hands, "I didn't see your surgery today, so I thought so, but now, I don't think so."

   He turned his attention to this new "tricuspid valve repair" device.

  Unfortunately, he can only see the operation process, but not the internal structure of the device.

  He couldn't modify Mayo's device either.

  The Fifth Academy of the Magic Capital is thriving here.

   And there was also a major breakthrough in the Kyoto First Hospital.
