How much of the trimmed flap is retained depends on the specific case. For some patients, the large flap is completely cut off, leaving only the root of the ru (homonym of "nipple") muscle, and the small flap can be completely retained with the chordae tendineae. The large flap and small flap here refer to the anterior flap and the posterior flap of the mitral valve. The anterior flap has a large area, so it is called the large flap. The posterior flap has a small area, so it is called the small flap.
The tissue that can be preserved must be sutured and connected to the artificial valve. The part of the artificial valve that is responsible for the connection is called the valve ring. In the second operation to remove the broken artificial valve, the first valve ring must be completely removed, which will undoubtedly remove and damage the original tissue of the human body.
It cannot be said that the surgeon did a bad job in the first surgery, which resulted in a strange shape after the second surgery. Rather, it was because the patient's own proliferative tissue on the artificial valve was not good, so the surgeon had to cut and cut the valve in the second surgery, and the regular shape of the valve orifice that the surgeon had worked hard to create in the first surgery had to be scrapped.
There is nothing we can do about it, bad organizations will be cut off.
After the surgery, if the surgeon's idea of arranging the flap opening can be judged, it will be helpful to trim the original human tissue and suture it again. Xie's eyes are sharp. The guidance he said pointed out that the surgeon's treatment of the subvalvular structure during the first surgery had retained the large flap, even though the surgeon had been forced to cut off part of it during the second surgery.
The surrounding environment of the preserved large subvalvular structure was judged again, and the protruding hypertrophy pointed out by Xie Wanying was found. The location and structure of this hypertrophy were very clever and scheming, like a little devil hiding in the patient's heart. If the doctor does not do calculations and does not think carefully, he will not be able to see the problem at first glance.
It seemed that something was amiss. To be able to fully develop his thoughts like Xie, he needed to think about it for a few more times. Doctor Yu was a little confused. He didn't dare to look at the surgeon with a questioning look for fear of being scolded. He could only look at Senior Shi Lei beside him.
Shi Lei remained silent. Ever since classmate Xie spoke, he kept his mouth shut even tighter, like a mute stone.
Having almost flipped over the car, he knew that Xie's ideas needed to be thought about again and again.

It is difficult to understand how this muscle affects the valve opening just by looking at it intuitively. We need to combine it with the Ru (homonym of "ru") head muscle mentioned by Xie Wanying. What is the biggest feature of the Ru (homonym of "ru") head muscle? It is movable.
In other words, what Xie was calculating in his mind was not only the static image of the valve but also the dynamic image of the valve.
When the cranial muscles pull the valve, it is definitely not just the valve that moves, but the entire heart. If the muscles near the valve opening do not move at all, it is absolutely inconsistent with human physiology.
It's like putting something into a hole. It's completely different whether the narrow hole you put the thing into is a completely fixed dead object or a movable living thing. The limit of the mouth of a dead object is much lower than the range limit of a living thing.
This is the point where we need to open our minds.
"Hmm." The surgeon made a sound, indicating that he had started to think.
"I see."
As his assistant spoke these words, Doctor Yu hung his head: His mind hadn't figured it out yet and was almost going crazy.
It is really difficult to be a doctor with a good brain.
Even though he couldn’t figure it out, it didn’t matter. Dr. Yu knew there was another way to think around the problem: look at the results.
