I Can See Health

Dai Wansong reacted immediately.

Lu Chen from the Heart Failure Conference?

He also participated in a heart failure conference some time ago, and his mind immediately recalled the young man who amazed everyone.

He looked at Lu Chen in front of him, with a hint of surprise in his eyes!

He remembered that Lu Chen was studying dapagliflozin?

Why did you come to their tavr class?

(TAVR is used instead of valve intervention below)

…

After a brief interlude, calm returned to the cath lab.

Dai Wansong took a deep look at Lu Chen.

Is it possible that this guy wants to cross research fields to engage in tavr?

"Let's continue..." Dai Wansong retracted his thoughts and began to continue explaining.

Everyone in the cath lab looked at Lu Chen from time to time.

Everyone has a little bit of curiosity about this mysterious young man.

On the operating table, Dai Wansong continued: "After the valve is successfully crossed, a hardened guidewire needs to be sent through the pigtail catheter for large sheath implantation through the vascular approach, delivery of the expansion balloon and valve system, and treatment of peripheral vascular complications. Processing. Does anyone know what kinds of tavr-hardened guide wires are available in China?

As soon as this question came up, the entire cath lab was silent.

This is already a very professional question. Everyone present is new to TAVR. They shouldn’t know this question, right?

Everyone looked at each other with no clue.

Dai Wansong looked at Bai Xin and was a little disappointed when he found that the latter had his head lowered and not looking at him.

So, he turned to look at Lu Chen who was standing aside.

Lu Chen saw Dai Wansong's gaze, paused, stood up, and said softly: "Currently, the two types of hardened guide wires available in China that are suitable for TAVR are lunderquist and amtz."

Lu Chen paused and continued: "The lunderquist guidewire is harder and more supportive than the amtz guidewire. It is suitable for almost all types of valves, but at the same time, the risk of complications such as guidewire perforation and cutting injuries is also relatively increased... …”

As soon as Lu Chen finished speaking, everyone in the cath lab looked at him.

Let me go, is this still a newcomer to tavr?

He actually knows so much about the current guide wires in the domestic market.

This time, no one had any doubts about Lu Chen's answer.

Being able to answer so fluently must mean that Lu Chen truly understands and is right!

Sure enough, a smile appeared on Dai Wansong's face, "Well said!"

He then added: "The curvature of the tip of the hardened guide wire must match the size and shape of the ventricular cavity, and there must be no edges or corners. Otherwise, fatal complications such as myocardial perforation may occur during valve delivery and release. It takes time during the operation. Note the position and tension of the guidewire within the ventricle.”

This is why there are currently only two types of hardened guide wires in China.

Because hardened guide wires are so important, once the matching fails, it will directly affect the success rate of subsequent surgeries.

"Let's try orbital establishment and balloon pre-dilation?"

Dai Wansong's words were addressed to Lu Chen alone.

All the students in the cath lab looked at Lu Chen with envy.

There are not many opportunities for this kind of practical operation!

It is very expensive to fake the simulated operating room, and the equipment required for each simulated operation consumes a lot of money.

"Okay." Lu Chen smiled and nodded.

He practiced for a long time in the system's virtual space last night, but this was also his first time operating in reality.

Slowly walked onto the stage and took over Dai Wansong's position.

…

There are still some differences between the system virtual space and the actual operation.

The real touch made Lu Chen's heart beat slightly faster.

This is not yet a real operation.

If it were a real human surgery, the string in Lu Chen's mind might be even tighter.

Lu Chen didn't get started quickly.

Instead, an appropriately sized dilation balloon is first selected based on ultrasound and CT measurements.

Then adjust the angle through the balloon marker and calcification position, place the middle part of the balloon in the calcified narrow area, and select the appropriate position according to the CT angle so that the target calcification area does not overlap with the balloon position, so that the balloon expansion effect can be observed.

Seeing Lu Chen's actions, so mature and sophisticated, Dai Wansong couldn't help but nodded slightly.

In his mind, with this level of proficiency, it was definitely not his first TAVR surgery!

After Lu Chen successfully completed the balloon pre-expansion, Dai Wansong did not shout to stop, but said with some expectation: "Lu Chen, don't stop, you continue!"

Lu Chen nodded.

This was a rare opportunity to operate in real life, so he concentrated even more.

The next step is valve delivery and release.

This is the top priority of the entire operation!

Lu Chen needed to transport the artificial valve to the location of the diseased valve and then release it successfully.

This is also the step that most tests the skill of the surgeon.

Dai Wansong looked at Lu Chen without blinking.

The reason why he let Lu Chen continue was because he wanted to see where the limits of his abilities were.

If he could complete this last step, it would prove that Lu Chen was ready to start his career.

…

In the cath lab.

All the students did not dare to express their anger, and they all stared at Lu Chen's movements.

Every step he takes touches everyone's nerves.

After balloon pre-expansion, if the valve is severely damaged, a large amount of regurgitation occurs, and the patient's hemodynamics is unstable, an artificial valve needs to be implanted quickly.

However, it was just a simulated surgery now, and without such worries, Lu Chen could not be in a hurry and just take it slow and steady.

The artificial valve is slowly transported under full fluoroscopy.

The early delivery of the valve went smoothly.

Lu Chen paused for a moment until he reached the aortic arch.

"Be careful here!" Dai Wansong reminded appropriately.

At this time, if the hardened guide wire cannot be pulled in, it will easily come out of the ventricle.

Lu Chen did not act in a hurry, but recalled the training steps in the system space last night in his mind.

He first adjusted his body position to the left anterior oblique position, then pushed the valve, and at the same time tightened the super-hard guidewire to avoid damaging the aorta during valve delivery.

However, no matter how Lu Chen adjusted the position, the valve could not be inserted.

…

Other students also discovered the abnormality in Lu Chen's operation.

"its stuck!"

"The valve can't go in...I guess the angle of the valve is too big and it can't go through at all!"

"Haha, let me tell you, UU Reading www.uukaｎshu.ｎ, Lu Chen will probably not be able to get in. Theoretical knowledge is only the facade, and the final operational skills are the first aspect."

"We are still in the training class now. It is already quite good to be able to achieve this level!"

Some people sigh with emotion, and some people rejoice in the misfortune.

However, Lu Chen was not affected at all.

"If it doesn't work, you can end the operation." Dean Dai Wansong said softly.

Dai Wansong was already very satisfied with Lu Chen's performance, even if he failed to complete all the steps.

At this time, Lu Chen slowly raised his head, without any trace of nervousness on his face. He put down the guide wire in his hand and said to Dai Wansong beside him: "Dean Dai, the simulated patient's aortic valve has a large angulation, and the artificial valve cannot be used." It was difficult to pass through the aortic valve orifice, so I needed snare to assist in crossing the valve and correct the artificial valve misalignment.”

"This..." Dai Wansong was stunned when he heard Lu Chen's words, "You want snare assistance? Why not use dual guide wire technology?"
