Chapter 870 Ablation of the scar area (second update)

catheter outside.

The senior doctors from the Kyoto Affiliated Hospital all looked very nervous.

"Director Yang, do you want to cut off the live broadcast signal?" An attending doctor hurried to Yang Feng's side.

"Okay, cut it off first!"

Yang Feng nodded, his expression serious.

In case the patient has any problems, it will be broadcast live, which is not good for the reputation of the First Affiliated Hospital of Kyoto.

Just as the doctor in charge of Huaxia wanted to return and informed the information department to cut off the live broadcast signal source, Shen Wenguang on the side made a sound.

"Director Yang, wait a moment."

At this time, Shen Wenguang's face did not show any tension or worry.

"Director Shen, this situation is not very good. Don't cut off the signal source, in case something happens..." Yang Feng gritted his teeth, with a serious expression on his face. He put his hands behind his back and couldn't help clenching his fists.

"Don't worry, Lu Chen can handle it well." Shen Wenguang still looked calm, "This kind of ventricular tachycardia ablation, after the patient's ventricular tachycardia is induced, ventricular fibrillation is inevitable, even if it is made I do it, and there is no way to avoid it [-] percent.”

"That's fine."

Yang Feng saw that Shen Wenguang, the director of Mayo, said so, and he was so calm.

What more can he say?
I can only call back the attending doctor just now, "Wait a minute, don't cut off the signal source."

After thinking about it, he also gave a magnificent reason, "Let all the audience take a look at the rescue, and don't think that the operation is all smooth sailing."

The attending doctor was a little confused.

This director Yang Feng's change before and after is too big!

However, as a young man at the bottom, he could only do what Director Yang Feng said.

……

The scene of rescuing the live broadcast really shocked the audience.

But after a brief surprise, they were even more amazed at Lu Chen's calm handling.

We all know that the ablation of ventricular tachycardia is very likely to induce ventricular fibrillation.

But how to deal with the emergence of ventricular fibrillation is another matter.

As a magician, Lu Chen showed his extreme calmness in front of everyone without reservation.

Cardiopulmonary resuscitation, defibrillation, intravenous CPR drugs.

Everyone has been skeptical at the beginning, and now they are silent.

Everyone was staring at the screen in the live surgery room, unwilling to move their eyes at all.

……

Finally, after the third defibrillation, the patient's ventricular fibrillation finally recovered!
"The sinus rhythm has been restored!" Xiao Shikang took a deep breath, and said to Lu Chen, "Continue with the operation?"

Lu Chen nodded without hesitation: "Continue!"

Ventricular fibrillation is inevitable!

Even if the operation is stopped this time, who can guarantee that there will be no ventricular fibrillation in the next operation?
If there is no operation, then this young male patient is likely to continue to live under the pain of electric shock!

This situation is something that no one wants to see.

"Okay!" Xiao Shikang didn't say much, he just glanced at Lu Chen blankly, as if recalling the time when Lu Chen had surgery in Kyoto.

Back then, Lu Chen was still quite young.

Seeing him, he has already become calm.

After the patient's ventricular fibrillation recovered, Lu Chen immediately started to measure the ventricular tachycardia.

"The distance and direction of the bipolar mapping catheter and the contact tissue will affect the qualitative and quantitative signal, which in turn will affect the results of matrix mapping based on voltage and abnormal potential."

Lu Chen said while talking.

What he said was naturally to Xiao Shikang beside him and the audience in the live broadcast room.

"In addition, the patient is suffering from dilated heart disease and myocardial remodeling, so there are many scars inside the heart, and the degree of delay of the local potential in the scar largely depends on its anatomical location."

These little skills are knowledge points that are not accessible to textbooks or ordinary practitioners.

Lu Chen explained it to everyone without reservation.

Many people in the live broadcast room are knowledgeable.

Many people immediately sat up straight and watched the live broadcast more seriously.

……

Twenty minutes later, Lu Chen stopped the mapping in his hand, and he turned to look at Xiao Shikang, "The mapping is complete."

Xiao Shikang was taken aback for a moment, the mapping was really fast!
Ordinary mapping, even if it goes smoothly, will take at least half an hour.

Lu Chen's speed is all due to his familiarity with the anatomy and electrophysiology of the heart.

This ability can be improved not only by simply increasing the amount of surgery.

It requires personal perception and understanding of surgery.

However, Lu Chen's expression did not relax at all.

Because the mapping is over, the next step is the more important ablation!
The patient is dilated cardiomyopathy.

In dilated cardiomyopathy, the heart gradually enlarges to compensate for heart failure.

In medicine, this enlargement of the heart is called "ventricular remodeling".

Myocardial remodeling means that there are many scars on the heart muscle.

The existence of scar area greatly affects the progress of ablation.

Xiao Shikang would like to see how Mayo's doctors deal with the ablation of the scar area.

At this time, Lu Chen had already prepared the ablation catheter, and he said in a deep voice: "The mechanism of ventricular tachycardia in the scar area is mostly related to the reentry mediated by the diseased tissue near the annulus and scar tissue!"

Xiao Shikang thought for a while and asked, "Then how can it be accurately ablated?"

If the ablation is not careful enough, the VT may recur.

The ablation range is too large, and there is a high risk of damage to the heart muscle.

This is the place where ablation tests the most for the operator. How to grasp the speed is the key to the success of the operation!
Lu Chen sent the ablation catheter into the patient's heart along the channel, and said with a smile: "This is to formulate different ablation methods according to individual differences."

"Generally speaking, we can divide it into the isthmus, outer ring, inner ring, and bystander according to the role of each part in the reentry loop. The isthmus can be subdivided into the entrance, exit, and central isthmus. Regionally determine the scar area and the isthmus-related area, and find the key isthmus through towing and mapping."

"As for ventricular tachycardia in non-ischemic heart disease, due to the complex pathogenesis, combined ablation of endocardium and epicardium is often required."

These surgical experiences were not imagined by Lu Chen out of thin air.

It is extracted from the surgical cases of the predecessors after hundreds of operations.

Lu Chen's biggest help is the system virtual space.

He has countless chances of trial and error!

Every failure is Lu Chen's most valuable experience.

The surgical experience he has accumulated so far is beyond the reach of many surgeons in their lifetime.

On the side, Xiao Shikang listened to Lu Chen's explanation, his eyes became brighter and brighter.

If it is said that Lu Chen in the past was just a little better at surgery, but now he has completely surpassed his cognitive range in terms of surgical operations and knowledge reserves.

Surgery Live.

The audience also heard Lu Chen's explanation.

Those who have been watching the live broadcast all this time are all serious and understanding of electrophysiological interventional surgery in the Department of Cardiology.

Everyone has learned more or less experience from Lu Chen.

The number of live broadcast audiences has increased, but the barrage has decreased.

Everyone was immersed in Lu Chen's art-like electrophysiological surgery.
