Chapter 2303

「Zheng Lao Ban, what is Baptista surgery? 」 Zhao Wenhua, taking advantage of the lull when nobody spoke, steeled himself and asked.

Zheng Lao Ban seems to have no particular hobbies, so trying to cater to his tastes is quite difficult; Zhao Wenhua kept probing, but so far he hasn't found a good entry point.

"It's a surgical procedure that removes the hypertrophied myocardium of the left ventricle in late-stage dilated cardiomyopathy," Zheng Ren said, "the mortality rate is relatively high, and it's not widely performed globally."

"High mortality? How high?" Zhao Wenhua stared for a moment.

"Old Zhao, are you deliberately stirring up trouble?" Su Yun said unhappily; he disliked Zhao Wenhua interrupting the surgery discussion, his words full of annoyance.

Lin Yuan stood to the side, saying nothing.

Baptista surgery, a procedure most commonly performed in Brazil, Zheng Lao Ban not only wants to introduce it but even wants to perform it using interventional surgery right away?!

She could no longer express her inner astonishment in words.

"The mortality rate is about 20%," Zheng Ren said, "that's Brazil's data; the US is a bit higher but performed less often. The UK's mortality is similar to the US's, and the procedure remains quite difficult."

"……" Zhao Wenhua felt his heart sink upon hearing the 20% mortality figure.

Zheng Lao Ban is playing with fire!

He's still young; having done TIPS surgery well, he starts toying with creating a new procedure whenever he has free time. A new procedure, by being new, means difficulty and unpredictable danger.

What on earth is he thinking? Isn't it fine to just complete the Nobel Prize procedure properly? If it were Zhao Wenhua himself, he'd cling to a single TIPS surgery for life and never think of changing it.

"There are many problems; although the surgical method itself is fine, the materials science issues are huge!" Su Yun said solemnly, a rare sight.

"We can ask Lanke about the materials," Zheng Ren said.

In the System Operating Room, Zheng Ren saw the anchor-point materials and sutures; to thread a guidewire through the heart's interior, DSA guidance posed no problem for him—the main issue was that the thread needed to withstand the tension from cardiac contraction and dilation, as well as anticoagulation concerns.

This point differs from the interventional surgery for left ventricular wall aneurysms.

The primary requirement is that the line not break; second, it must not form a thrombus. Only a breakthrough in materials science could make this procedure feasible.

"Knock knock knock." The knocking sound came.

The man who had been sitting on the curb last night, head in hands, weeping, held the film in his hand and stood timidly at the doorway.

Upon seeing the familiar faces of Zheng Ren and Su Yun, his heart felt a slight reassurance.

This is room 912; anyone able to wander in a white coat in the ward's doctors' office shouldn't be a con artist… right?

"Here." Su Yun furrowed his brows at the patient's family, his tone completely lacking the ease and joking from last night.

"Um…" The patient's family member froze for a moment; this serious tone was completely unlike last night's.

What's going on? He bent his waist and sneakily glanced at Su Yun.

"Hand over the film so I can take another look." Su Yun reached out directly.

This was unlike what he imagined; the patient's family member blankly handed over the film.

How did the two kind young doctors from last night become so stern?

The chest X-ray was taken out, and Su Yun placed the film onto the viewer.

With a "pa" sound, like Su Yun's determination.

"Good grief…" Zhao Wenhua, upon seeing the film, immediately understood what Zheng Lao Ban and Su Yun had been arguing about just now.

Normally, the cardiothoracic ratio on a chest X-ray should be about 1:2. But the heart enlargement visible on this film is extremely obvious—far beyond 1:2, nearly reaching 1:1.

In other words, the lower half of the left pleural cavity is almost completely occupied by the heart.

Can a heart like this even undergo interventional surgery? Zheng Lao Ban is practically trying to ascend to heaven.

In Zhao Wenhua's view, not only is interventional surgery out of the question, but even regular surgery can't be done. For patients with this myocardial pathology, you might as well just tell them to go home.

In Zhao Wenhua's mind, such a severe disease simply has no treatment options.

"Here, this kind of heart, you're telling me to do interventional surgery on it?" Su Yun tapped his finger on the film in the viewer, making a thumping sound.

"Yes. A small thoracotomy, you watch the left ventricular part." Zheng Renye stepped up to the viewer and said seriously: "I'll go via the inferior cervical vein, through the superior vena cava into the heart, and advance the needle along the right ventricle adjacent to the interventricular septum. I'll penetrate the heart and handle the internal anchor point; you'll secure and tie the external anchor point."

It sounds simple, but actually doing it would be harder than climbing to heaven.

"I know the procedure, but we lack the supplies." Su Yun said, "Let me call Xiao Feng to ask."

"He probably doesn't have it either, but let's ask; if not, we'll hurry to contact Lanke."

Su Yun began to make the call, half-believing, half-doubting.

Sure enough, Feng Xu Hui had no spare of this high-end consumable.

And Orchid Science Asia-Pacific Regional President Smith said the company is researching this kind of consumable, and specifics still need to be consulted with headquarters. His words were rather vague, and he did not give a clear answer.

Zhao Wenhua listened quietly, not uttering a word.

Orchid Science—what kind of entity it is—Zhao Wenhua knew clearly. Although he could act arrogantly when dealing with Orchid Science salespeople, the highest level he had ever contacted was merely the manager of Orchid Science's Di Du region.

Zhao Wenhua couldn't even get in touch with the domestic general manager, let alone the president of the Pan-East Asia region.

And in contrast, Zheng Lao Ban couldn't even be bothered to make a phone call; the whole process was handled by his assistant Su Yun. Moreover, not even the Di Du regional general manager or the domestic regional general manager were on their radar—with just one phone call they directly reached the Pan-East Asia regional president.

Zhao Wenhua thought, the gap between people really is huge.

The patient's family member stood at the office doorway, at a loss. He didn't know what had happened, and no one communicated with him; all of this was completely different from what he had imagined.

Information about the patient was being passed back and forth among several people, with no one exchanging any words, and the office atmosphere was somewhat oppressive.

"Zheng Lao Ban, what are you guys doing?" Director Kong was about to go have lunch; as he passed by the doctors' office, he glanced in, saw that something seemed off, and asked.

"Director, I'm waiting for a reply from Orchid Science," Zheng Ren said in a low voice, his eyes fixed on the film on the viewer.

"Huh? What's wrong?"

Director Kong walked in, pleased, and looked up to see that glaring chest X-ray.

Um…… advanced dilated cardiomyopathy—what is Zheng Lao Ban researching?

"Zheng Lao Ban, is there a problem with the cardiovascular internal medicine treatment?" Director Kong asked.

His first thought was internal medicine medication—cardiotonics, diuretics, bronchodilators, etc., for symptomatic treatment.

However, after saying that, Director Kong immediately realized that Zheng Lao Ban had just said he was waiting for a reply from Orchid Science.

Orchid Science?

Orchid family!
