A private hospital on the outskirts of Natick, Massachusetts, quiet and peaceful, birds chirping from time to time, and the years are quiet.

But the quiet years are only the appearance, and in the conference room on the top floor of the hospital, the atmosphere is solemn, as if winter is coming.

CEO Jack Jones sat at one end of the long table in the conference, looking at the various medical data on the projection screen opposite, his face was gloomy.

The patient is a crown prince from the Middle East, and at the age of 78, he has long lost the possibility of becoming king, but he has a high status and ...... Lots of money.

But as we get older, money can't reverse the aging of the body.

His muscles gradually slackened and weakened, and his heart began to have problems. Although the most advanced technology is used for treatment, it has come to the point of severe mitral regurgitation, massive regurgitation and heart failure.

In Jack Jones' view, His Excellency Crown Prince Abdul Aziz is facing death, perhaps now, perhaps in the near future, and he will die quietly at some point.

This is the best outcome, and it is always much better than heart failure, prolonging a meaningless life with a machine.

One month ago, Crown Prince Abdul Aziz came to the United States to seek treatment. After consultation with top-level specialists, surgical procedures are ruled out first.

Crown Prince Abdul Aziz is too old and his heart function is particularly poor, and thoracotomy is an insurmountable chasm for him.

It is indeed difficult for the elderly to withstand the huge blow of thoracotomy surgery, and even general anesthesia can stop Abdul Aziz's frail heart beating anytime and anywhere.

Abdul Aziz was honored because of his status and money, but it was because of his status and money that no doctor was willing to take a huge risk to perform surgical treatment for him.

The failure of the operation will trigger a series of complex issues such as Abdul Aziz's huge family and inheritance. And those who are sorcerers will undoubtedly be pushed to the foreground and baptized by the storm.

After consultation with the top cardiac surgeons in the United States and even in the world, it was finally decided to use interventional surgery for minimally invasive treatment.

The mitral valve is located at the apex of the heart in the body and is the valve between the left atrium and the left ventricle. The mitral valve acts like a door that blocks blood from entering the left atrium.

When the mitral valve is affected by various reasons and there is an organic lesion, as the heart contracts, a part of the blood enters the aorta normally, but because of mitral regurgitation, the other part of the blood enters the left atrium and does not participate in blood circulation.

If there is only a small amount of regurgitation, the body is able to adapt itself, which is the so-called compensatory period.

However, as mitral regurgitation increases, the return flow into the left atrium can reach more than 50% of the left ventricular output.

In this case, the left atrium receives blood from left ventricular regurgitation in addition to blood from pulmonary venous return.

Thus, increased left atrial pressure can lead to increased pressure in the pulmonary veins and pulmonary capillaries, which can lead to dilation and congestion. At the same time, the left ventricular diastolic volume load increases, resulting in left ventricular enlargement.

After a series of reactions, the patient's condition became worse and worse, and finally the balance was broken, and even getting out of bed and walking became an extremely luxurious thing.

The patient can only lie in the hospital bed, minimizing the body's demand for arterial blood and giving the weakened heart a chance to survive.

Ranko's mitral valve clips have a limited effect, and clinical trials are only effective for a subset of patients, but only a small percentage of patients.

However, due to various pressures, as well as Abdul Aziz's physical condition and willingness, he underwent mitral valve closure under interventional surgery.

And Abdul Aziz's mitral regurgitation is to some extent more suitable for Ranko's new product.

Minimally invasive surgery is a small blow to the patient and is within the tolerance of Abdul Aziz. Jack Jones also knows that interventional mitral valve closure can only have some benefit for the patient's condition, but it cannot cure it.

It can extend his life by a few years, and Abdul Aziz is also satisfied with this.

So 23 days ago, Professor Saipan Carr performed interventional surgery and performed mitral valve closure surgery on Crown Prince Abdul Aziz with new consumables from Ranko.

Surgery...... The effect is hard to describe.

Abdul Aziz did get better after the operation, which is good news. But before 1 week passed, the patient's condition took a turn for the worse, and he had severe heart failure again.

After a series of rescues in a private hospital controlled by Rank, Abdul Aziz barely survived in this world and did not return to God's side.

Because of the rapid deterioration of the situation, Abdul Aziz's family invited the world's top cardiac surgeons and circulatory interventionists for consultation, and the consultation was held in the Ranco hospital.

"The situation is clear, and I would recommend taking the risk of surgery. "Ultrasound evaluation showed that the patient had a very large posterior lobe prolapse of 23 mm, with both P2 and P3 prolapses and a regurgitant neck width of 13 mm. Severe mitral regurgitation results in poor heart function and low blood pressure. Professor Saiban Carr has fulfilled his mission, and it turns out that interventional surgery is not yet perfect and there is no way to ......"

Jack Jones didn't listen to what was next, he was quite disgusted by this statement. He knew what the doctor meant, but the doctor's words somewhat negated years of Ranko's efforts.

"Surgery is a huge risk, and I don't believe that any doctor wants to do it. Even if Professor Saipan Carr had been able to convince the crown prince, I would not have performed such an operation with a success rate of less than 30%. Stephen Dudley, from Mayo, said from a chair dressed in white.

As a doctor from the Mayo Clinic, Stephen Dadley, who claims to be the strongest cardiac surgeon in the world, still gives a lot of weight. Except for Wu, who was far away in the sky, no one could ignore his judgment.

He directly cut off the possibility of surgery.

But Stephen Dudley doesn't seem to be enough, continuing, "Even if the 30 percent chance of it happens, the sheer trauma of surgery is still a problem. After recovering after surgery, Crown Prince Abdul Aziz still has more than half of the chance of death. ”

"That's what I suggested. ”

"Interventional surgery has proven to be limited by existing technology and unable to accomplish this impossible mission. Professor Saiban Carr retorted.

Next, the interventional doctor and the psychic surgeon start an argument that upsets Jack Jones.

The failure of the operation not only means that the friendship in the Middle Kingdom cannot be obtained, but more seriously, the mitral valve clip that Ranco has invested heavily in research and development cannot be used in clinical practice.
