Chapter 749 -749: It Seems, Found It! (Extra for Alliance Hierarch Hua Hua Lang Zi 3)

“Non-invasive vascular clamp.”

“Gauze!”

“Hemostasis!”

…

As the surgery progressed, Tao Zi personally assisted, while Qian Lin looked at Chen Cang, fuming yet not daring to speak out. However… his now greatest enemy had successfully advanced to include two people.

The first was none other than his old man!

The second was that Chen Dog!

It wasn’t to say that Chen Cang was as important as his dad.

Nor was it that his dad and Chen Cang were equally despicable!

Anyway… these were the goals Qian Lin strove for in his life.

Tao Zi now quite enjoyed assisting Chen Cang, regardless of whether the main operator’s coefficient was given to Chen Cang or not.

After all… a thief in apprenticeship must have the enlightenment of a thief.

Not paying tuition was one thing, but surely he couldn’t also be earning money, right?

Ever since Chen Cang had learned to perform cardiac surgeries, Tao Zi always felt that he was the second to benefit, having learned quite a few valuable things.

In the past, when provincial consultations for surgeries occurred, they would always first invite Xia Gaofeng, then Tao Zi. But lately… it was different.

They started inviting Director Tao first!

The outside world had come to recognize that Director Tao was a late bloomer with great potential building up over years!

This made Director Tao quite happy indeed.

However, the good days were numbered. Thinking that Chen Cang would fly away after the new year, Tao Zi was actually the one who found it hardest to let go.

Yet, unexpectedly, before leaving he would still have the chance to learn from Chen Cang’s mitral valve operation.

To call it learning was one thing; it was more about inspiration, actually.

Gaining what he needed from someone else’s surgery was exactly what Director Tao needed.

Once the atrium was opened and the right atrium entered, Chen Cang held the scalpel and made a vertical incision at the fossa ovalis, expanding it upwards and downwards.

Chen Cang glanced at Qian Lin and said,

“When extending downwards, it’s best to veer towards the direction of the inferior vena cava; when extending upwards, it’s important to avoid an inward bias, as doing so can prevent accidental damage to the aortic sinus.”

This technique was an epiphany of Chen Cang’s, perhaps pointless to Tao Zi,

but for Qian Lin and his classmate, it was a rare piece of experience.

Qian Lin suddenly had an epiphany, and his gaze towards Chen Cang softened a bit…

Should he let him off the hook?

Dextromethorphan, a central nervous system stimulant, could cause tachycardia as an adverse reaction if taken in large quantities.

This was all acceptable.

But if it induced atrial fibrillation, that couldn’t be accepted.

What was atrial fibrillation?

It was the irregular and disordered ineffective contractions of the atrium, which changed the atrial rhythm, and made the ventricular contractions irregular, with atrial fibrillation speeding up the ventricles.

This could trigger a series of serious diseases including cerebral arterial thrombosis, peripheral vascular thrombosis, pulmonary embolism, and sudden cardiac death!

Therefore, often times, what patients felt was palpitations.

But when atrial fibrillation occurred frequently, complications would arise.

Thinking of the first patient, who had pulmonary embolism and had also experienced atrial fibrillation!

The second patient, too, felt palpitations and atrial fibrillation induced multiple cavity infarctions.

Now onto the third patient, who still suffered an infarction!

Initially, Chen Cang thought the cough syrup might induce damage to the vascular endothelium, but now it seemed to act directly on the heart.

Thinking of this, Chen Cang became concerned.

How many patients nationwide had pre-existing conditions prone to infarctions?

If this kind of cough syrup became prevalent, what kind of outcome would it lead to?

Qian Lin hesitated!

In fact, Chen Cang was often quite agreeable.

Chen Cang continued, “You need to lose some weight, since chubby hands can affect your performance.”

Classmate A held back, not daring to laugh, and farted as a sign of respect!

Qian Lin’s hands trembled. Where is my scalpel?!

Tao Zi just smiled.

It was normal to joke around in the operating room. Chen Cang wasn’t too bad, but Zhang Youfu loved to tell risqué jokes; at first, he often made the nurses blush, but now the young nurses frequently told Zhang Youfu jokes that made him blush.

The mitral valve replacement surgery involved a mitral valve that had become narrowed, with severe leaflet retraction and significant subvalvular disease, making repair by reconstruction impossible. The valve had to be replaced.

The heart contains many valves that allow blood to flow from the atrium to the ventricle. These valves act as one-way doors in the heart, only opening one way. Each contraction of the heart opens these valves once, similar to machinery.

Because blood must flow only one way, it cannot be allowed to flow backward; the role of the valves is to block blood when it tries to flow back.

But the mitral valve serves as a one-way door between the left atrium and left ventricle. When the mitral valve is stenosed or fails to close properly, blood flows back into the heart, leading to cardiac disease.

What Chen Cang needed to do was to replace this valve with a new artificial one, achieving the same function.

However, there were excess parts of the valve that were severely retracted and no longer usable, even keeping them was of little significance.

Chen Cang simply cut it out, a process succinctly known as valve excision. But care had to be taken not to remove too much to avoid damaging the ventricular wall.

The operation continued at this slow pace when suddenly, Chen Cang paused!

He discovered a problem!

That was the presence of some small thrombi residuals on the wall of the left ventricle.

Chen Cang suddenly froze.

Without close observation, it would have been very difficult to notice this issue!

Moreover, it was fortunate that Chen Cang’s vision had improved by fifty percent, which allowed him to detect this detail.

What was going on here?

Chen Cang then quickly checked the original mitral valve area.

It suddenly dawned on him that, when the heart was normal and the blood flow unimpeded, but when the mitral valve was narrowed, the blood couldn’t flow into the left ventricle from the left atrium at a normal speed!

Moreover, the blood accumulating and swirling in the enlarged left atrium, with reduced flow speed, could lead to the formation of tiny blood clots.

And these clots were all ticking time bombs!

If they reached the coronary arteries, it was coronary heart disease; if they reached the cerebral vessels, it was cerebral infarction!

A prolonged mitral valve constriction could lead to changes in cardiac structure, such as the enlargement of the left atrium!

And the enlargement of the left atrium was closely related to atrial fibrillation, which was the most common cause of cardiogenic embolism.

No wonder the patient had suffered two cerebral infarctions in a short period.

Everything had a reason.

However, this patient suffered from this particular condition because of mitral valve stenosis.

What was the significance of the cough syrup then?

That’s right!

Chen Cang began to examine along the major blood vessels.

Something was wrong!

Chen Cang suddenly realized something, he might have been off track.

He had been linking the infarctions to the cough syrup all along.

Leading him to always associate the formation of the clots with the cough syrup and overlook the direct cause of the infarctions!

That was the atrial fibrillation!

All at once!

Just as Chen Cang had come to this realization, he saw the progress of the task in his mind increase by five points!

At that moment, Chen Cang was overjoyed!

Could it be…

The cough syrup was the cause of the atrial fibrillation?

Yes!

It was highly possible!

Everything seemed to become so serious all of a sudden!
