The original mechanical valve had problems, so the doctor had to be more careful when replacing it with the same mechanical valve.
An obvious disadvantage of mechanical valves is that they are not as compatible with the human body as biological valves. The surrounding tissues are prone to proliferate, affecting the operation of the mechanical valve, and causing stenosis again is also a headache for doctors.
When the surgeon removed the previous mechanical flap, typical hyperplastic tissue was indeed found.
When a new mechanical valve is connected to the patient, the connection part needs to be carefully repaired to avoid the same situation from happening again next time.
Whether an operation is done well or not is reflected in the doctor's skills in these details.
You can just drop one petal and it will work anyway, or you can "fine-tune" the joint to make it a perfect fit.
While he was operating, the surgeon suddenly stopped, threw the surgical instruments onto the nurse's instrument table next to him, and placed his hands in the glove pockets on the chest of his surgical gown.
Du Yeqing's eyes behind his glasses looked very serious.
Each surgeon has his or her own style. Some doctors are very straightforward and think that’s good enough. Anyway, human medical research is constantly progressing, and what we do now may lead to better results. If the operation time is too prolonged, it may be detrimental to the overall health of the human body.

Du Yeqing is not like that. He is an extremely rigorous and conservative doctor with high requirements for surgery. He believes that making do with implants is not his principle for performing surgeries. I would rather spend more time thinking about it and make sure the surgery is done as meticulously and as perfect as possible within the time limit. No matter what the future of medical research holds, being a doctor is about doing your best under existing conditions, and he doesn't like to gamble on the future.
Of course, his demanding requirements will not only bring greater pressure to himself, but also to others.
For such surgeons, the people they dislike the most should be the auxiliary staff in the operating room.
The other assistants dared not follow the surgeon and stood by with surgical instruments in hand, responding to the surgeon's orders at any time.
"I don't know how long the operation will take." Du Meng'en sighed secretly.
Zhang Shuping didn't respond. This is why cardiac surgery is notoriously long.
When implanting something in other parts of the human body, there is no need to consider the needs of the entire body as carefully as with cardiac surgery.
Seeing that the surgeon did not move, the extracorporeal circulation doctor and the anesthesiologist became a little nervous and needed to consider the possibility of extreme situations.
Shen Youhuan, who was standing at the door, had a more serious expression on his face. He might be wondering whether he should go find Zhang Huayao to check on him.
After the child was born, Zhang Huayao went to meet the patient's family first. The safe birth of the child means that half of the mission has been completed, and the 20 million can be obtained. This must be a joke. Zhang Huayao left because the next cardiac surgery would be performed by doctors in his own hospital who were familiar with the operation and he didn't need to worry too much.
The operation reached a stalemate.
At a time like this, no one in the operating room had the heart to think about dinner.
His stomach was rumbling and Du Meng'en felt like he was about to faint from hunger, but he didn't dare to complain.
Finally, the surgeon on the operating table murmured, "Tell me, what's the problem?"
Several assistants gathered there to help the surgeon think about the problem. To be honest, if they had really thought of it, the first and second assistants would have spoken up long ago. Why delay it until now? It didn't seem like Du Yeqing was just asking the assistant on the operating table, but everyone watching the operation in the operating room.
