Chapter 929: Chapter 804: A Genius Is Either Mad, Crazy, or Both!_3

"Are you snapping the blackboard, or are you taking photos of Senior Brother Song?"

"I’m photographing the blackboard, of course."

"Then why are you aiming at Senior Brother Song?"

"I’ll take photos of whatever I please."

The girls nearby silently also lifted their phones.

"If the tricuspid valve is completely obstructed, wouldn’t the cardiovascular circulation be interrupted by the blockage of the valve? How then can the patient still live until 12 years old?"

"Survival always has its reasons. Since there is no gate, there must be a hole somewhere else. Therefore, such patients usually have either a patent ductus arteriosus or a ventricular septal defect, using these abnormal pathways to complete the circulatory route."

"Got it."

"To treat this case, Dr. Fontan summarized his experience and invented an almost crazy surgical procedure—directly connecting the superior and inferior vena cava to the pulmonary artery, completely abandoning the right ventricle."

"His thinking was very clear; since the tricuspid valve was closed, blocking the normal pulmonary circulation, we know that the pulmonary artery connects to the right ventricle, and the tricuspid valve closure prevents blood from the right atrium from entering the right ventricle. At this juncture, the circulation is forcibly interrupted; with no blood from the right atrium returning to the right ventricle, how is blood supposed to be ejected from the right ventricle into the pulmonary artery to acquire oxygen?"

"Alright, Dr. Fontan declared—let go of the right ventricle. We let the heart handle only systemic circulation and find another way to achieve pulmonary circulation."

"With what method? Directly connecting the superior and inferior vena cava to the pulmonary artery. Previously, it was superior vena cava—inferior vena cava—right atrium—right ventricle—aorta. Now, I bypass the obstructed area and go directly from superior vena cava—inferior vena cava to pulmonary artery."

"Without the heart’s beating, how does blood enter the pulmonary artery? Blood relies on the heart’s pump action, whether entering the aorta or pulmonary artery. Now, without a pump, how does the blood flow in?" A student truly couldn’t grasp it.

"It shows you’re thinking about the problem!"

Song Zimo, chest puffed out, walked between the rows; his white gown swung open like a trench coat. His tall stature of 1.86 meters, paired with a handsome face, left the female students sitting there absolutely captivated.

Under the guise of studying, the girls were able to brazenly take photos of Song Zimo with their phones.

"At that time, every cardiac surgery department in the world thought this—pulmonary circulation must rely on the right ventricle pumping blood to the pulmonary artery under the heart’s beating. Without the heart’s pumping action, blood simply couldn’t enter the pulmonary artery. Otherwise, what’s the point of having a right ventricle and right atrium? Hence, this plan seemed impossible to work."

"But a genius is a genius; a genius is either mad, or a fanatic, or both!"

When saying this, Song Zimo’s gaze fell on Yang Ping, lingered for a moment, and then he continued.

"Dr. Fontan’s thinking was completely different from others."

"Dr. Fontan was very confident that this plan would work, and at that point, Dr. Fontan introduced a middle school physics concept: pressure difference!"

"We know that water flows through pipes with pressure, and blood being a liquid, of course, has pressure when flowing through blood vessels. Systemic circulation needs to pump blood to the entire body, which has high pressure and belongs to high pressure circulation, while pulmonary circulation only pumps blood to the lungs, which is low pressure circulation. So, systemic circulation and pulmonary circulation have a pressure difference, and this pressure difference ensures that blood returning from the superior and inferior vena cava will definitely flow toward the pulmonary artery."

"The foundation of Dr. Fontan’s theory was this middle school physics concept."

"Moreover, as we just mentioned, these patients often have perforated septa between the right and left atria. Once Dr. Fontan created this vascular shortcut, the direct entry of blood into the pulmonary artery would just perfectly separate the blood flow of the right and left atria, thus avoiding mixing."

"Why did this little girl have cyanosis? Because of hypoxia. And why hypoxia? Because of a faulty circulation, which caused oxygen-rich blood to mix with oxygen-poor blood."

"Dr. Fontan’s surgery went from concept to being prepared to be performed on a little girl without even conducting animal experiments. But the genius firmly believed in his own correctness. He overcame all opposition, conducted the surgery on the little girl, and it was very successful."

"Why didn’t he just buy ten pigs to experiment first, and then use it on humans? He couldn’t have been unable to afford pigs, right?"

A female student asked Song Zimo.

"He couldn’t find any pigs with tricuspid atresia!" A male student debated with the female student.

The girl was unyielding: "Why does it have to be pigs with tricuspid atresia?"

"If you don’t buy pigs with tricuspid atresia, how can you simulate this case?"

"You all are victims of fixed thinking. Even normal pigs can undergo the shortcut procedure. If the pigs can live normally after the shortcut, then the surgery is a success. If they can’t survive, then the surgery has failed."

The male and female students formed two opposing sides for the debate, their thinking as lively as a quarrel.

The male voices were loud, the female voices piercing.

Zhang Lin looked at Yang Ping, ready to intervene, but seeing the smile on Yang Ping’s face, he immediately abandoned the thought and sat back down in his chair.
