Chapter 945 Serious Plaque

Time cannot stand the memory.

Many things have passed in the long river of time early.

Lu Chen "investigated" in Jinghua for a week.

During this period of time, it can be regarded as a long vacation.

Before, Lu Chen was too busy!

Clinical and scientific research matters are too messy.

Taking advantage of this time, you can take a proper rest.

In Jinghua, while discussing with Li Yao about Jie Qing, Lu Chen asked what precautions should be taken.

On the other hand, he helped the intervention room of Jinghua Second Hospital to explain the key points of new surgeries such as TAVR.

With Lu Chen's current ability, this is a great opportunity for the entire Jinghua Second Hospital.

Under the leadership of Lu Chen and Gu Xinyue, many doctors in Jinghua Second Hospital have made great progress in interventional surgery.

A week later.

Lu Chen, Ke Yue, and Gu Xinyue successfully completed the mission and returned to the Fifth Hospital of Shanghai.

The trip to Beijing is officially over.

Back at the hospital, Lu Chen continued to concentrate on sorting out the matters related to the "Jieqing" application.

He will work hard to win the "Jieqing"!
Ke Yue continued to handle the work of the National Key Performance Laboratory.

Gu Xinyue also returned to the clinic and continued to start her surgical career.

At this time, it was less than two months before Lu Chen's final application for the outstanding youth.

……

With Lu Chen's current conditions, he has actually passed the "Jie Qing" review.

But, just like Ke Yue said.

The assessment of outstanding youths is no longer just an academic issue.

It also involves the medical background and network resources behind each person.

This is no longer academic!

It is the resources behind everyone!

When he was in Beijing, Li Yao also talked about these things with him.

But Lu Chen's stubborn character made him not plan to go through the back door.

On the other hand, Lu Chen started from scratch.

If you want to compare resources with those second-generation students, you will definitely not win!
Except this way.

Lu Chen decided to use his own ability to fight against the "Jieqing" selection system.

If your ability is one or two grades higher than your opponent, the result may be different!

"If one new type of project doesn't work, then two!"

Lu Chen muttered to himself.

He currently has a project.

It is about transcatheter mitral valve replacement in patients after acute myocardial infarction.

Besides that, he's looking for another project!
……

After Lu Chen's searching and thinking.

Hard work pays off!
He found another way and did not continue to look for projects on valve intervention.

After all, the valve project was almost wiped out by himself.

Except for valvular intervention.

Among all the surgeries in the Department of Cardiology, coronary intervention is still one of the most common surgeries.

The idea of ​​Lu Chen's new project this time came from a patient's coronary intervention.

……

Modu Fifth Hospital, outpatient building.

Nowadays, director Lu Chen's consultation number is hard to find!

In the hands of some scalpers, Lu Chen's consultation registration fee even exceeded 800 yuan!
It was close to thousands of dollars at one time!
For this reason, the Shanghai Fifth Court is now severely cracking down on scalpers.

Today, in Lu Chen's consulting room, an old man came to see a doctor.

The patient was a 66-year-old male.

Suffering from grade 2 hypertension (very high risk, 2-year history of hypertension), type [-] diabetes.

He went to a local hospital 3 months ago because of chest tightness. Coronary angiography showed severe stenosis of the coronary artery, and PCI was performed.

This time, because of "more than 3 months after PCI", I came to Shanghai Fifth Hospital again.

The old man's original words were: "I don't trust the small hospital down here anymore. After surgery, I still have chest tightness. The technical level is too poor!"

Lu Chen could only explain while helping the uncle to see a doctor.

"Master, I just read your information on interventional surgery, the operation was very successful!" Lu Chen said, "There is no such thing as a failed operation or poor technique!"

It is said that literati are indifferent.

Between medical staff, it is also easy to have a situation of being insignificant.

But Lu Chen has always adhered to his own point of view.

Between peers, don't underestimate each other!
"Professor Lu Chen, tell me, I just finished the operation, why do I have chest tightness again?" the old man asked suspiciously.

Lu Chen smiled, "This is caused by various reasons. Intervention with PCI cannot solve all problems, and everyone has individual differences."

The patient has a USB flash drive of surgical video data in his hand.

After Lu Chen got it, he opened it.

Coronary angiography at a local hospital showed.

The patient's anterior descending branch, diagonal branch, and obtuse marginal branch all had moderate to severe stenosis, and the proximal and middle segments of the anterior descending branch were mainly narrowed and calcified.

After watching the video, Lu Chen frowned, "This is not easy, the blood vessels are too calcified!"

"Can't you? You can't have surgery!" Hearing this, the old man panicked instantly.

Lu Chen smiled, "Don't worry, it can be done, but the vascular calcification is serious, and surgery is risky."

"Okay, I can trust you!"

The old man said seriously.

After coming to the hospital, he already understood the intervention level of Shanghai Fifth Hospital, which was at the level of NO1.

And Lu Chen also found an opportunity at this time.

Perhaps from the perspective of coronary intervention, I can think of a new project!
……

Soon, under the leadership of Lu Chen.

There was another big discussion within the department.

Angiography indicated that there were severe calcification shadows on both sides of the lesion vessel and the length of the lesion was long.

Therefore, Lu Chen decided to adopt the Sonico-CX shock wave balloon technology solution.

The impact precisely impacts the coronary artery intima and submedial calcifications to loosen them.

Subsequently, OCT was used to evaluate the rupture of the calcified ring and the condition of the lumen after shock wave balloon therapy.

Finally, the stent was reimplanted, and the postoperative effect was evaluated again under OCT and contrast-enhanced ultrasound.

……

After a brief discussion, coronary intervention began.

This operation mainly deals with the anterior descending artery disease.

According to the preoperative examination, the proximal and middle sections of the anterior descending artery of the patient were 70% stenotic with severe calcification (the length of the lesion was about 30 mm, and the diameter of the most calcified part was 3.0 mm).

Injection of the FFR pressure microcatheter into the anterior descending branch revealed a FFR of 0.73.

OCT examination showed diffuse annular calcified plaques in the proximal and middle segments of the anterior descending artery.

……

Intraoperative.

Lu Chen chose the 3.0mm*12mm Sonico-CX coronary shock wave balloon.

At the proximal and middle calcified lesions, 70 shock waves were triggered successively for 7 cycles.

In each cycle, 4 pulse shock waves were excited at 10atm, and then pressurized to 8atm to expand and shape.

In the implementation of calcified plaque fragmentation, under DSA, it can be seen that with the release of shock waves, and after 8 atm expansion, the balloon is fully inflated at the most calcified area.

……

The entire operation was broadcast live globally simultaneously again.

China, Europe, America, Japan and other countries, live broadcast the whole process.

After sufficient shock wave balloon pretreatment, the calcified ring was released, the compliance of the blood vessel was improved, and the stent was successfully implanted in the lesion.

Re-examination of OCT and angiography showed that the stent was well adhered to the wall, and the expansion was satisfactory. The expansion rate of the stent was 86.24%, and there was no dissection and residual stenosis.
