Chapter 310 Interventional Maglev Very Compact Artificial Heart

"What do you mean?" Luo Ya can't speak Chinese well and doesn't know the word "Guotai Minan".

Zhou Qiao told her that it was something that almost every Chinese person longed for. Although it sounded ordinary, it actually had great ambitions.

Suizai carefully explained the meaning of "the country is peaceful and the people are safe".

Luo Ya smiled and gave two thumbs up: "As long as it comes from my father, it's fine!"

After a pause, he added: "I also thought of four names, English names, do you want to hear them?"

Zhou Qiao clapped her hands and shouted: "Okay! I'm in charge of the Chinese name, and you're in charge of the English name. The division of labor is clear, which is great!"

"Haha." Luo Ya smiled with a heroic look, revealing two rows of brilliant teeth.

Although Fang Yuanyuan is also heroic, her aura is worlds apart compared to Luo Ya's. After all, Fang Yuanyuan is just the youngest daughter, while Luo Ya occupies a high position, holds great power, and is a big boss.

"Which four?" Zhou Qiao asked.

Loya: "Klein, Gehrman, Sherlock, Lumian."

Zhou Qiao suddenly fell into deep thought. It sounded so familiar. He seemed to have heard it somewhere.

"The sunset on the horizon is so beautiful, come and take a picture for me!" Luo Ya's smile was like a spring breeze blowing on her face, she stretched out her arms and struck a beautiful pose.

Zhou Qiao stopped worrying about where he had seen the name and immediately went to take photos of Luo Ya.

Anyway, as Luo Ya said, as long as it is the name given by the father, then, similarly, as long as it is the name given by the mother, it is also good!

Generally speaking, the pregnancy period is about 280 days, about 40 weeks.

Children born within 3 weeks before the expected date of delivery, that is, after 37 weeks of pregnancy, and within 2 weeks after the expected date of delivery, that is, within 42 weeks of pregnancy, are all babies born normally and are called full term. childbirth.

Luo Ya is only 19 weeks pregnant now, which is just over half way. There is still plenty of time. However, Luo Ya has already started to prepare various small clothes, small shoes, small scarves, small gloves, small socks, small toys, cartoon small bottles, and babies. Cars, cribs... and even plan to raise a group of cows and sheep. The organic milk and organic goat milk produced in the family farm will be simply pasteurized and given to the children for drinking.

As for the various high-end milk powders on the market, you can stock up on as much as you want. Anyway, just a little more. If you can't finish it by then, and there are still a few months until the due date, give it to the servants in the manor to drink. It won't be wasted either.

This is the love a mother has for her child.

In the wine estate, a children's playground covering several acres is already being built for babies to play after they are born.

I have to say that a child born with a silver spoon in his mouth is quite happy. Even the territory and family property decades from now are ready.

One takes over the East African empire, one takes over the French nuclear power plant and the Italian mafia family, one is a powerful figure in American politics and may be able to challenge the presidential throne, and the other takes over its commercial companies in the United States.

Zhou Qiao felt ashamed. After he sown the seeds, he didn't care much about it. He thought about spending more time with Luo Ya in the future.

If a child is born in the United States, and the mother is a standard American, and becomes a U.S. citizen at birth, he is eligible to run for president.

In fact, although Loya was born abroad, her mother had the foresight to apply for American citizenship for her as soon as she was born. She could also run for President of the United States.

……

In addition, with Zhou Qiao here, Sequoia Hospital was immediately confident. Dare to accept any patient.

Previously, when Zhou Qiao was away, some critically ill patients or those whose conditions were quite difficult were recommended to be transferred to a major hospital in Houston.

Although Zhou Qiao can be connected remotely, the old troublesome Zhou Qiao is not good either. Moreover, the remote connection is only for guidance, and they have to do the specific operations, so they are not so sure.

But now, Zhou Qiao is here, which is much more convenient.

……

There is a local uncle in Crystal Mills County, fifty-two-year-old Athol Conway. A few years ago, he was an excellent hunter and often ventured deep into the mountains and forests.

However, five years ago, something went wrong with his body, and he developed symptoms of chest tightness and shortness of breath. Later, it became more and more serious. Not to mention hunting, his daily life was obviously affected.

I also went to another major hospital in Christ Mills. The doctor diagnosed me with chronic heart failure and recommended conservative treatment.

Therefore, in the past few years, I have been receiving conservative treatment in that hospital. Basically, I have to stay in the hospital for half a month or more than a month every year.

However, the condition can only be relieved but cannot be cured. Over the past few years, it has naturally become more serious.

In the past, it was only intensified in autumn and winter, but now it is also serious in summer.

Especially these days, it seems like I can't even walk thirty meters. The family suggested hospitalization, but Athol Conway heard that the newly built Sequoia Hospital was good. Not only did the medical conditions be better, but the charges seemed to be cheaper than similar hospitals.

This is because Loya's original intention of establishing the hospital was to get votes, so it had a charitable nature.

So Uncle Athol Conway, accompanied by his family, came to Sequoia Hospital for treatment, and was treated by a senior doctor in the Department of Cardiology.

It turned out that the condition was quite serious. Without detailed examination, just listening to the symptoms showed that simply using drugs to adjust the heart function would not have much effect, so he was transferred to cardiac surgery.

After consultation with cardiac surgeons, everyone agreed that heart transplantation and artificial heart implantation were his hope for survival.

However, Sequoia Hospital has not yet performed such a difficult surgery. Fortunately, Dr. Zhou is here.

Dean Joachim Langre invited Zhou Qiao again.

It was still Luciana, the little black beauty, who picked her up.

Zhou Qiao led doctors from the Cardiac Surgery Department and Cardiology Department of Sequoia Hospital to further improve the examination items and analyze the patient's condition.

Echocardiography revealed that Uncle Athol Conway's left ventricular ejection fraction (EF) was only 7% at its lowest, which was seriously lower than normal. Usually, the EF of a normal person is at least greater than 50%.

At the same time, the left heart was enlarged, accompanied by severe mitral regurgitation, cardiac insufficiency, the right heart was enlarged, accompanied by moderate to severe tricuspid regurgitation, pulmonary hypertension, and trace pericardial effusion.

This is already in the end stage of heart failure.

To put it simply, the heart is failing and has become completely old and has reached the point where it has to be replaced.

EF represents the heart's ability to pump blood, and 7% means that the heart is no longer able to beat. Coupled with persistent atrial fibrillation, Uncle Athol Conway's situation is not optimistic and requires timely surgical intervention.

For the treatment of patients with advanced heart failure, there are currently only two methods: heart transplantation and artificial heart implantation. Zhou Qiao led the team to conduct an evaluation and work together to formulate the most suitable plan for the patient.

In fact, he can analyze the condition and formulate surgical plans by himself. Now he is leading the team "step by step" because he wants to give the cardiac surgery department and cardiology department of Sequoia Hospital an opportunity to experience and grow.

If it were another hospital and it didn’t have tens of thousands of dollars, it wouldn’t be possible to ask him to share “a lesson”, let alone teach him step-by-step. But Sequoia Hospital is Luo Ya’s team, and Luo Ya has to give birth to four children for him. I have to contribute.

Luo Ya spent US$5.8 million just to give him a watch.

In the end, Zhou Qiao led a team of doctors to formulate a treatment plan that used an "artificial heart" to coordinate with the original heart.

66% of the patient's HLA class I antibodies were positive, and the cardiopulmonary exercise test result was VO2/kg 8.0ml/min/kg. What does this mean?

This shows that the risk of transplant rejection for patients is quite high. Generally, the risk of rejection for HLA class I is less than 10%.

Heart transplantation requires plasma exchange first and then surgery within a short period of time after the replacement. Not only is the risk of the operation high, but the patient's data shows that the incidence of postoperative rejection will be very high.

Therefore, combined with the cardiopulmonary exercise test, the patient's indication for ventricular assist is clear.

There are actually two types of artificial hearts. One is the auxiliary artificial heart, which retains the patient's original heart and places an auxiliary device next to it to work in conjunction with the original heart. The auxiliary artificial hearts include left ventricular assist, right ventricular assist and biventricular assist.

The other is to replace the real heart with an artificial mechanical heart, which is a complete artificial heart.

Zhou Qiao plans to choose an LVAD product from Boston Medical Company.

Boston Medical Company, a company owned by Academician Domitri, is also a leading company in the medical device industry in the United States. It is currently working closely with Future Medical Devices Company controlled by Zhou Qiao.

Get products from Boston Medical Company, where not only the quality is guaranteed, but the price is very affordable.

Of course, this is not the most important.

The most important thing is that the latest artificial heart launched by Boston Medical Company is far ahead in all aspects of parameters.

Its core component, the blood pump, weighs only 90 grams. The blood pump has a diameter of 34 mm and a thickness of 26 mm. It is the smallest and lightest interventional fully magnetic levitation artificial heart in the world.

Using it for surgery is less invasive during surgery and allows for quick recovery after surgery. Moreover, the total weight of the external controller and battery worn for a long time after surgery does not exceed 800 grams, allowing patients to travel lightly.

This is not Boston Medical’s first-generation VAD product, but its third generation.

Since it was Zhou Qiao who wanted the goods, they were delivered quickly.

Zhou Qiao also called and chatted with Academician Domitri. They hadn't seen each other for a long time. The old man said that he missed him very much and asked him to come to Boston again when he was free.

In addition, Academician Domitri said that there will be an opportunity for academic exchange next month, and he will go to the University of Tokyo Hospital in Japan and ask if he is interested.

Then, Academician Domitri's research institute is about to test a new drug in Japan and needs to go there to do some experiments and collect some data. I also want him to try leading the team.

"Conducting new drug trials in Japan?" Zhou Qiao was surprised.

He only heard that the United States was conducting new drug experiments in some backward countries such as India, Ukraine, Romania, Tunisia, Lithuania, Brazil, and Argentina, but he did not expect that it was also conducted in Japan.

In fact, it also exists in Korea.

The United States is the father of those countries and already has military bases. Experimenting with new drugs is a trivial matter.

"Teacher, what kind of test is it?" Zhou Qiao asked.

Academician Domitri said: "It is resistant to nuclear radiation. In a radiation emergency, people may be exposed to radiation doses ranging from negligible to life-threatening. You also know that Fukushima discharged a large amount of nuclear-contaminated water into the sea , there is a mass base for conducting experiments there, and many volunteers are willing to cooperate.”

"The new drug I developed, I named it DOZO 16-1, is a metal ion chelating agent that can selectively combine with metal elements in the F region of the periodic table, lanthanide series and actinide series to form a complex , and are quickly excreted from the body with excrement.”

"In addition, its dosage form is an oral capsule, which is easier to store than intravenous drugs, and easier to use and manage in emergency situations. What is currently being done in Fukushima is mainly human Phase I safety and tolerability clinical trials."

"Of course, there is still a certain amount of radiation in Fukushima. If you don't want to, the teacher won't force you. You just need to go to Tokyo to participate in academic exchanges."

Zhou Qiao thought for a while and said, "I am willing to go. Give me this opportunity." As for Murphy and Stephanie, Zhou Qiao decided not to let them go.

Firstly, Iris Clinic is quite busy, and secondly, there is radiation in Fukushima, so girls should try not to go there.

As for himself, he already has quadruplets. In addition, he also has a system that can remove radiation from his body at any time without being contaminated.

Academician Domitri said: "You can think about it again and let's talk about it when the time comes."

After hanging up the phone, Academician Domitri thought that if Zhou Qiao was willing to go, he would have to give him some compensation. After all, he was taking risks.

The old man paid him specially, so he would not be stingy.

Academician Domitri is considering carving out some shares in some of his companies, such as Boston Medical Company, and letting Zhou Qiao participate first.

The gossip spread by previous research institutes is not groundless.

In fact, if you only stay around Fukushima for a short period of time and do not enter the nuclear restricted area, the impact will not be too great.

New drug trials only recruit volunteers who are contaminated or slightly contaminated in that area. The experimental location can actually be chosen elsewhere.

……

After receiving the compact magnetic levitation artificial heart, preparations for the operation began in full swing.

This is not a simple operation, it can be said to be extremely complex.

There are also many people participating.

Medical staff from cardiac surgery, ultrasound, anesthesia, intensive care unit, extracorporeal circulation and other departments and fields all come with the purpose of learning.

It's a pretty rare opportunity.

With the attention and cooperation of so many people, Zhou Qiao led the team members to perform left ventricular assist system implantation + tricuspid valve valvuloplasty for the patient.

At the beginning of the operation, Zhou Qiao first performed a right heart catheterization to re-evaluate the right ventricular function, and then performed tricuspid valvuloplasty.

As soon as the expert makes a move, he will know if there is any.

Exact positioning, threading, placing and fixing...

With perfect surgical skills, an ultra-small fully magnetic levitation artificial heart weighing only 90 grams was implanted into the patient's body.

The artificial heart pump head was successfully installed, the blood pump speed was set, and it ran successfully.

Everyone cheered because this operation, which carried hope, was easily successful!

The "artificial heart" rotates gently, assisting the patient's struggling heart and maintaining his life.

This artificial heart may not look small, but its pumping volume is quite large, with a displacement of 50 mL and a cardiac output capacity of 10L/min, which is quite powerful.

After the operation, Uncle Athol Conway, who was equipped with a "turbo booster", was transferred to the intensive care unit and underwent a series of subsequent treatments.

Cardiotonic drug support, diuresis, inhaled nitric oxide to reduce pulmonary artery pressure, etc. can reduce his right ventricular pre/afterload. At the same time, medical staff will also guide Uncle Athol Conway in adaptive training of the artificial heart.

The heart surgery performed by the top celebrity Dr. Zhou will naturally not cause any major problems. Uncle Athol Conway will be discharged from the hospital soon!
