Brazil, at the heart treatment center of St. Sao Paulo hospital.
Dr. Domingo Paul personally collected various data and made a preoperative assessment.
It was like doing a math problem. First of all, a person needed to calculate the amount of cardiac muscle to be removed through various clinical values.
According to the law of clapplace: T= 2p ×R, which meant that the larger the volume and diameter, the higher the liquid tension (P), and the higher the container tension (T).
After examining a large number of animal heart samples and human heart samples with dilated cardiopathy, Baptista came to a similar conclusion. M=4.18×R3, where M is the left cardiac wall tension, and R is the left cardiac diameter.
The expansion of the left chamber would cause the tension of the left chamber to increase proportionally and increase the oxygen consumption, which would reduce the efficacy of the left chamber. He assumed that all the heart’s functions improved after the diameter was reduced.
The goal of left chamber reduction surgery was to reduce the left Chamber’s diameter to re-establish a new relationship between left chamber volume, tension, and diameter.
As the research went deeper, the recent research on the Frank peaks Starling mechanism could not be used to explain end-stage heart failure.
The expansion of the left ventricle in patients with advanced myocardial infarction might be a negative compensation for the damage to the heart, and left chamber reduction surgery might affect the process of this vicious cycle.
Simple atrial septal defect reconstruction could also improve the heart function of some patients with end-stage myocardial infarction. Other simultaneous surgeries such as coronary artery bypass surgery could also help the recovery of the left heart.
After the left chamber was reshaped, it was no longer spherical, so the contraction of the left chamber was more coordinated and the distortion of the heart was reduced. Other possible factors included changes in blood volume and peripheral blood vessel tension, as well as supplementary medication.
Theoretical research was only theoretical research. Mathematics problems still had to be done.
Due to the limited number of heart donors, the heart treatment center of Sao Paulo hospital in Brazil was the best in the world when it came to left chamber reduction surgery.
The number of surgeries performed each year was also far ahead of other hospitals. Dr. Domingo Paul was one of the most outstanding doctors. Ever since Dr. Randas Baptista invented left ventricle surgery in 1996, he had been performing many such surgeries.
After massive and complicated calculations and surgical simulations, Dr. Domingo Paul was shocked to find that the complexity of the patient’s surgery was far beyond his imagination.
A lot of heart muscle had to be removed during left ventricular reduction surgery. In a sense, the amount of heart muscle tissue removed was proof of the difficulty of the surgery.
Up until now, the surgery with the most resection had removed 302g of the heart muscle.
However, according to his own calculations, at least 330g of the patient’s heart muscle had to be removed for the surgery to be considered a success.
After Dr. Domingo Paul studied it carefully, his first thought was to give up on the operation.
However, after the patient had vaguely expressed to the relevant personnel that he had contacted, that if the surgery was successful, he would donate to the heart treatment center, he changed his mind.
Especially when he saw the patient’s son and got the check, Dr. Domingo Paul decided to give it a try.
The patient’s condition was very bad. Because he had flown half the world, the symptoms of heart failure were extremely serious. Even with the use of the left ventricular assist system, the patient’s condition still continued to worsen.
On the third day, John Hopkins’s intensive care team was invited to St. Paolo, where Dr. Domingo Paul was the chief surgeon.
The entire surgery was extremely difficult. After 11 hours and 22 minutes, the surgery was barely completed.
Although the surgery was successful, Dr. Domingo Paul finally measured the size of the left ventricle. It was 343g!
He had increased his previous record by 41g!
It should be known that every 10g of blood that was removed was a threshold, and the difficulty of the surgery would increase exponentially.
This was because it meant that the condition of left ventricle was more serious. The patient’s body was in a worse condition, and the surgery and perioperative period risks were high.
But!
No matter what, he had successfully completed the surgery.
Dr. Domingo Paul was proud of this.
The patient was sent to the ICU for postoperative treatment and care, which was taken care of by a professional team from Johns Hopkins Hospital.
On the third day after the surgery, Dr. Domingo Paul stood outside the transparent isolation room and looked at the values displayed on the monitor. He was very satisfied.
This was the world’s highest level of fusion, regardless of whether it was in surgery or during the perioperative period. The best surgeon and the best intensive care team had greatly reduced the mortality rate of patients.
“It seems that the patient will recover very soon.” The assistant of Dr. Domingo Paul said happily.
“Yes.”
“Doctor, you’re the best at left chamber reduction surgery. You’re the best in the world.” The assistant said happily.
Dr. Domingo Paul believed that his assistant was telling the truth.
He was currently organizing the data and medical records related to the surgery into a research paper and publishing it. “This thesis is like a bomb, shocking the medical world,” Domingo thought.
“Doctor, it is estimated that within the next 20 years, you will keep the record of removing cardiac tissue with left chamber reduction surgery.” His assistant continued,”this is your field. No one else can step foot in it!”
“Hahaha!” Domingo Paul laughed happily.
The previous record was held by his competitor, naiyi Amaral. The time taken for the surgery did not mean anything. Surgery was not a race, and being fast did not mean anything.
Moreover, the number of successful surgeries that the two of them completed each year was about the same. Nay had always been ahead of Domingo Paul because he had once performed a surgery to remove 302g of heart muscle in the left chamber.
This was a natural chasm that separated Dr. Nay Amal from other doctors who performed similar surgeries.
This time, Dr. Domingo Paul had surpassed the record and increased it by 41g!
Domingo believed that he could maintain his record for 20 years, and that was a conservative estimate. It wasn’t an exaggeration to say that this record might be sealed on the altar forever.
As for nai…She was no longer the king of left chamber plastic surgery. The title of King had already fallen on his head.
“Now you know how powerful you are,” Domingo laughed happily. As he left the intensive care unit, he met nay Amala.
Domingo Paul walked over with his head held high, completely ignoring nay’s existence.
Naiyi had treated him like this in the past. He could finally look down on him! Domingo was overjoyed.
“Doctor, I’ll start organizing the information. Should I send the paper to the lancets or …” Domingo Paul’s assistant asked for his opinion.
“I’ll take the lancets. ” Domingo was in a good mood. He smiled and said,””Then I’ll be more interested in the new breakthrough in surgery.”
“This paper will definitely change the stubborn Americans ‘opinion on the appearance reduction technique.” Dr. Domingo Paul’s assistant added,”“343g! That’s an outrageous number. Those Americans are probably going to question the authenticity of our surgery again. “
