A private hospital in the suburb of Natick, Massachusetts, is quiet and peaceful. Birds cry from time to time. The years are quiet and good.


    But the quiet years are just appearances. In the conference room on the top floor of the hospital, the atmosphere is as solemn as if winter is coming.


    CEO Jack Jones sat at one end of the long conference table, looking at all kinds of medical data on the opposite projection screen.


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


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


    His muscles began to relax and his heart began to have problems. Although there is the most advanced technology for treatment, it has reached the stage of severe mitral insufficiency and massive regurgitation with heart failure.


    In Jack Jones''s view, crown prince Abdul Aziz has faced death directly. Perhaps now or in the near future, he will die quietly at some time.


    This is the best result, which is much better than heart failure and prolonging meaningless life with machines.


    One month ago, crown prince Abdul Aziz came to the United States to seek treatment. After consultation with the top experts, the means of surgery were excluded first.


    Prince Abdul Aziz is too old and his heart function is particularly poor. Thoracotomy is an insurmountable gap for him.


    It is really difficult for the elderly to bear the great blow of thoracotomy. Even general anesthesia may stop the old and weak heart of apudul Aziz anytime and anywhere.


    Apudule Aziz was honored because of his status and money, but because of his status and money, no doctor was willing to carry out surgery for him at great risk.


    If the operation fails, the contradictions of a series of complex problems such as apudule Aziz''s huge family and inheritance will be triggered. As practitioners, there is no doubt that they will be pushed to the front desk and baptized by the storm.


    The top cardiac surgeons in the United States and even the world finally decided to use interventional surgery for minimally invasive treatment.


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


    When various reasons affect the mitral valve and organic lesions appear, with the contraction of the heart, part of the blood normally enters the aorta; However, due to mitral insufficiency, another part of blood enters the left atrium and does not participate in blood circulation.


    If there is only a small amount of reflux, the human body can adapt itself, which is the so-called compensation period.


    However, with more and more mitral regurgitation, the regurgitation into the left atrium can reach more than 50% of the left ventricular output.


    In this case, the left atrium receives not only blood from the pulmonary vein, but also blood from the left ventricle.


    Therefore, the increase of left atrial pressure can cause the increase of pulmonary vein and pulmonary capillary pressure, followed by 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 broke through the balance. Even getting out of bed for a walk became an extremely luxurious thing.


    The patient can only lie in the hospital bed to minimize the body''s demand for arterial blood and give the weak heart a chance to survive.


    LANCO''s mitral valve clamp has limited effect, and the clinical trial can only be effective for a few patients.


    However, due to the influence of various pressures and the physical condition and willingness of apudule Aziz, mitral valve closure under interventional surgery was performed.


    Moreover, apudul Aziz''s mitral regurgitation is more suitable for LANCO''s new products to some extent.


    The impact of minimally invasive surgery on patients is very small, which is within the scope of Abdul Aziz. Jack Jones also knows that mitral valve closure under interventional therapy can only be beneficial to the patient''s condition, but it can not be cured.


    Abdoul Aziz is also satisfied that he can prolong his life by several years.


    Therefore, 23 days ago, Professor Saipan Carr performed interventional surgery and performed mitral valve closure for crown prince apudul Aziz with new consumables from LANCO.


    The effect of surgery... Is indescribable.


    After the operation, Abdul Aziz did get better, which is exciting news. But a week didn''t pass. The patient''s situation turned sharply, and there was serious heart failure again.


    After a series of rescue in the private hospital controlled by Lanke company, apudule Aziz barely stayed in the world and did not return to God.


    Because of the rapid deterioration of the situation, apudule Aziz''s family invited the world''s top cardiac surgeons and circulatory interventional doctors to consult in this hospital of LANCO.


    "The situation is clear, and I still recommend risking surgery," said a circulatory interventional doctor, "Ultrasound evaluation showed that the patient had a large range of posterior lobe prolapse, up to 23mm, P2 and P3 prolapse, and the width of reflux neck was 13mm. Severe mitral regurgitation led to poor cardiac function and low blood pressure. Professor Saipan Carr has completed his mission, and facts have proved that the interventional technique is not perfect and can''t be..."


    Jack Jones didn''t listen to the following words. He was quite disgusted with this statement. He knew what the doctor meant, but what the doctor said denied LANCO''s efforts over the years to some extent.


    "Surgery has great risks. I believe no doctor is willing to do it. Even if Professor Saipan Carr can convince the crown prince, I won''t do such an operation with a success rate of less than 30%." Stephen Dudley from Mayo, dressed in white, sat in a chair and said.


    As a doctor from the Mayo Clinic, Stephen Dudley, who is known as the strongest cardiac surgeon in the world, gives his opinions with great weight. No one can ignore his judgment except Wu, who is far away.


    He cut off the possibility of surgery directly.


    However, Stephen Dudley seems to feel that it is not enough, and continues, "even if 30% of the possibility becomes a reality, the huge trauma of surgery is still a problem. After postoperative recovery, crown prince Abdul Aziz still has more than half the chance of death."


    "That''s my suggestion."


    "Interventional surgery has proved that limited by existing technology, it is impossible to complete this impossible mission," retorted Professor Saipan Carr.


    Next, the interventional doctor and the extracardiac doctor had a quarrel, which upset Jack Jones.


    The failure of the operation not only means that the friendship in the kingdom of the Middle East cannot be obtained, but what is more serious is that the mitral valve clamp invested by LANCO company cannot be used in clinic.
