When doctors have a simulated operating room

The old lady's condition was indeed thickened ventricular wall in Zhang Yi's eyes.

And a lot of blood was blocked in the ventricle and couldn't get out.

The blood in the ventricle couldn't get out, but the blood in the left atrium was constantly transported in.

So left heart failure and pulmonary edema occurred, and even the left atrium was enlarged.

Looking at the aorta, the outflow tract of the left ventricle, the vascular passage of the entire trunk was not narrowed.

Including the examination form handed over by Wang Xiaomian, the angiography examination also showed that several trunk blood vessels were indeed not narrowed.

The only problem is that the ventricular wall is thickened, squeezing the outlet of the aortic outflow tract.

It caused a slight narrowing of the outflow outlet.

But this is not a big problem and should not be the root cause of heart failure.

(The blood in the pulmonary vein exchanges oxygen and carbon dioxide through pulmonary breathing, enters the left atrium-left ventricle-aorta, and then sends oxygenated arterial blood to the whole body from the aorta, a large blood vessel.

Therefore, many heart failure pulmonary edema are related to aortic valve stenosis. Aortic valve stenosis, blood can not go out, which can also cause this situation.)

That's very strange.

While watching the examination, Zhang Yi took another look at the patient's heart.

Zhang Yi has eyes that face the lesion, so he can find the problem faster by looking directly.

Gradually.

Zhang Yi's eyes are getting more and more wrong.

There is even a sense of shock and disbelief!

However, it was fleeting, and others did not notice what Zhang Yi had discovered.

At this moment, Zhang Yi was trying his best to suppress his inner shock.

Because he discovered a very strange phenomenon!

The blood flow rate of this old lady's heart is a little different from that of normal people.

When the blood from the left atrium enters the left ventricle, the blood flow rate is normal.

However, because the ventricle becomes smaller, the blood flow rate becomes faster when the blood from the ventricle flows into the aorta!

The blood flow rates of the atrium and ventricle are different!

And a pressure difference is generated!

This pressure difference causes the mitral valve of the atrium to be sucked to the side close to the aorta by the pressure difference when it opens to eject blood from the ventricle.

It just happens to be close to the aorta, causing the outflow to be blocked.

In other words, this patient does not have vascular stenosis or other serious problems.

It is just because the blood flow rate is different, a pressure difference is generated, which causes the blood in the ventricle to be unable to be discharged.

This has caused such a series of problems!

It's just that this problem is difficult to find out through various examinations.

Because the patient does have left heart failure.

The shape of the heart, blood flow, angiography and even electrocardiogram are the same as heart failure caused by aortic valve stenosis.

So it is difficult to find out by examination alone.

Fortunately, Zhang Yi is a chosen one.

He can see the key to the problem as soon as he arrives.

But...

What causes this problem?

The blood flow rate of the atrium and ventricle is different? !

It's really weird.

This is really too rare!

Although Zhang Yi can perform many cardiac surgeries.

But he has never seen this disease before, and he has not drawn a treatment plan in the system.

Do surgery?

But there is no need for surgery without stenosis.

Take medicine?

But what medicine can solve the problem of different blood flow rates?

It is impossible to cut off the sucked mitral valve, so that there is one less "door" between the atrium and ventricle...

Oh.

For a while, the wrinkles between Zhang Yi's eyebrows deepened a little.

"How is it?"

Wang Xiaomian looked at Zhang Yi's expression and asked in a low voice.

"I have seen the patient's condition. Let's go to the office to discuss it first." Zhang Yi said.

Just as a group of doctors were about to leave the ward.

The family member who yelled before actually stopped them!

"Director Wang? You said that the expert you found is such a young man?!"

The family member looked unfriendly and looked at Zhang Yi with distrust.

Wang Xiaomian stepped forward and explained:

"Don't look at this doctor's young age. He performed the first thoracoscopic coronary artery bypass grafting in our hospital with a beating heart. No, I did it with him."

Looking at the surprised expressions of the people around him, Wang Xiaomian quickly added the second half of the sentence.

He remembered that Zhang Yi had not yet been certified, so he could not say that Zhang Yi was the main surgeon alone, but that he and he did it together.

However, the family member still did not believe it.

Because she didn't understand it either.

Just looking at Zhang Yi's age, he doesn't look like an experienced doctor.

"Humph! What heart-beating surgery? I don't understand! Anyway, I'm telling you! If anything happens to my mother, I will definitely settle accounts with you!"

The family member pointed at Zhang Yi and Wang Xiaomian's nose while saying this.

"Don't think I'm afraid of you because I came all the way to the mainland and I don't have friends! As long as my mother has something wrong, you will definitely be involved!"

Faced with the accusations of the family members, Wang Xiaomian was also helpless and could only continue to patiently say:

"Please wait a moment, let's have a meeting to discuss it first, and we will notify you immediately when there is a result."

At this time, several other family members next to her also advised:

"Yes, Aling, don't be so irritable, wait a little longer for the doctor to see the situation."

The family member named Aling retreated to the bed after several people next to her persuaded her kindly.

But she still didn't look at these doctors well.

In fact, the doctors were also a little unhappy, but they could only continue to think of ways to treat the old lady.

Who let them be doctors?

In the office.

Zhang Yi looked at the check list in his hand again and again.

He kept thinking about the cause of the disease and how to treat it.

He kept recalling the information in the medical books or papers he usually read.

This was the first time Zhang Yi had seen such a situation.

After thinking for a long time, he planned to figure it out by himself.

But if he continued to think about it, he was afraid that the patient would be exhausted.

So he asked the system.

"System? Give me some advice?"

[Hint, Bernoulli equation! ]

Zhang Yi:...

Can you not give some powerful hints? !

Your hint is too obscure!

You mentioned an equation to me for a heart disease...

No!

Zhang Yi suddenly became serious!

Bernoulli equation?

Bernoulli equation? !

"Oh shit!"

"That's right! The most famous corollary of the Bernoulli equation is that when the flow is at equal height, the greater the flow rate, the smaller the pressure! Right, right, right! That's it!"

Zhang Yi got it!

Although that thing is a very, very, very rare heart disease.

It was not even discovered until the 1980s and 1990s.

But so far, there are cases that can be used as reference.

Zhang Yi put a check list in front of Wang Xiaomian and asked:

"Director Wang, I think I have roughly deduced the reason."

In the office, all the doctors raised their heads!

They all looked at Zhang Yi in surprise!

What?

How long have you been reading the check report?

You have the result? !

In the corner, Lu Gao looked at Zhang Yi with a pursed mouth.

Humph!

He doesn't believe it!

Zhang Yi pointed at the ultrasound report and said:

"First of all, the examination shows that the heart wall is thickened, but several main blood vessels are not narrowed. But if you look at the back, it says that the compliance is reduced.

Reduced compliance means that the pressure difference is unbalanced, which means that the blood flow rate of the heart has changed."
