After being separated from my family, I became a darling of the military region thanks to my medical

As soon as the morning shift ended, Ye Zhen closed the duty log and left Gao Yuan, Liu Xiaohe, and Li Hong alone.

The calendar on the wall turned a page; there were still more than forty days left until the three-month period she and Gu Zheng had agreed upon.

Gao Yuan stood by the door, holding the morning's surgical schedule in his hand.

"Professor Ye, today we had three interventional procedures: two for atrial septal defects and one for pulmonary valve stenosis."

Liu Xiaohe took over the conversation.

"The patient in the catheterization lab No. 2 with pulmonary valve stenosis is a two-year-and-eight-month-old child weighing 10.6 kilograms with a transvalvular pressure gradient of 72 mmHg."

Ye Zhen pulled out the medical records for catheterization lab number three from the schedule.

"The first ward was vacant, Gao Yuan was the lead surgeon, and Liu Xiaohe was the first assistant."

Gao Yuan's fingers tightened slightly.

"Aren't you going to hold the show?"

"I'm on stage."

Ye Zhen handed the medical record back.

"Today we're not testing how steady your hands are, but whether your brains will stop working when faced with unforeseen circumstances."

Li Hong entered carrying a stack of sterile packs. Upon hearing this, she slowed her pace considerably.

"Professor Ye, more than a dozen interns have come to the demonstration room, saying they want to watch today's surgery."

Ye Zhen looked up.

"Can the catheterization lab hold so many people?"

Li Hong shook her head.

"It can't be stuffed in."

"Last time they stood outside the lead glass, the people in the front row could see the screen, but the people in the back row could only see the backs of other people's heads."

Gao Yuan was also somewhat helpless.

"After the surgery, we will send the imaging data to the demonstration room for a review."

"But what really needs to be said happens during the surgery."

Ye Zhen walked to the window and looked across the corridor at the closed double doors of the catheterization lab.

The angiography images in the catheterization lab can only be displayed on two monitors in the sterile area.

If you want to see the demonstration room, you can only wait until the surgery is over.

By the time the images are sent over, the most crucial minutes have already passed, and we've already figured out why the guidewire stopped, why the occluder was changed, and why the blood pressure suddenly dropped.

Ye Zhen pointed to the floor plan of the catheterization lab on the wall.

"The adjacent demonstration room is less than ten meters away from the catheterization lab."

"Could you send the imaging images directly?"

Li Hong was stunned.

"Send it to TV?"

"Send simultaneously."

Ye Zhen spoke calmly.

"One step is performed in the catheterization lab, and one step is displayed on the screen next door."

Gao Yuan frowned.

"Wouldn't that require modifying the machine?"

"The machine must not be tampered with."

Ye Zhen took out a pen and marked the third catheterization room on the scheduling sheet.

"Come on stage first."

Nine o'clock in the morning, catheterization lab number three.

The three-year-old girl has been anesthetized and is lying quietly on the operating table.

She has a secundum atrial septal defect, which is not large, but is located close to the root of the aorta.

Last night, Gao Yuan went through the ultrasound, angiography, and occluder models three times, and the edges of the medical record folder were worn and wrinkled.

The father of the sick child stood in front of the signing table, his pen hesitant to come down.

"Dr. Ye, I've read the newspaper."

The man's throat felt tight.

"I'll accept you."

Gao Yuan stood to the side without saying a word.

Ye Zhen opened the surgical consent form and pointed to the column for the chief surgeon.

"Today's surgeon is Gao Yuan."

"I will supervise the entire process in the operating room, and I will be responsible for handling any problems that arise."

The child's father glanced at Gao Yuan, his face full of hesitation.

"Can he really do it?"

Ye Zhen put the pen on the table.

Don't worry.

The man's face flushed as he looked down at the medical record.

Gao Yuan walked over and picked up the heart model on the table.

"The child's deficiency lies here."

He tapped the spot on the model with the pen cap.

"After inserting the occluder, you must avoid the aortic valve and mitral valve."

"I can perform preoperative angiography, intraoperative measurements, and pre-release follow-up examinations."

"If even one step in the process fails to meet the standards, I would rather withdraw from the project than force it to continue."

The man stared at the model for a long time before finally writing his name.

"Dr. Gao, please help me."

Gao Yuan took the consent form, his palms sweaty.

Ye Zhen had already put on her gloves and entered the sterile area.

After the perspective is activated, black and white images flicker on the monitor.

Gao Yuan established a pathway via the femoral vein, and the guidewire was inserted into the left upper pulmonary vein. The operation was carried out without any delay.

Liu Xiaohe is responsible for recording stress data.

"Right atrial pressure 8."

"Pulmonary artery pressure is 26."

"Left atrial pressure nine."

Ye Zhen stood to the side and behind Gao Yuan, without urging him on.

After the high-resolution balloon was inserted and contrast agent was injected, the edges of the defect gradually became visible.

"15.2 millimeters missing".

Liu Xiaohe reported the values.

Gao Yuan picked up the pre-selected occluder and slowly inserted it into the sheath.

After the left atrial disc opened, the position on the screen suddenly seemed a bit off.

The upper edge of the occluder was pressed too close, leaving only a small gap at the root of the aorta.

Gao Yuan stopped pushing the lever in his hand.

"Teacher Ye, the aortic side edge is too short."

Ye Zhen bent down to look at the front and side views.

"Don't put it down."

"Replace the eccentric occluder with the zero-degree end facing the aorta."

Gao Yuan immediately retreated.

Liu Xiaohe handed over the spare model quickly and efficiently.

After the second deployment, the occluder adhered to the edge of the defect, the aortic valve functioned normally, and the mitral valve blood flow was not affected.

Gao Yuan took a deep breath.

"Prepare for release."

Ye Zhen raised her hand and pressed down on his wrist.

"Perform another lateral angiography."

Gao Yuan did not hesitate.

Contrast agent is injected, and residual shunt is zero.

"release."

Unscrew the push rod.

The blocking device on the screen was firmly in place.

When the surgery was over, the child's father stood at the door. When he saw Gao Yuan come out, he was stunned for a moment, and then bent down.

"Dr. Gao, I apologize for what I said earlier."

Gao Yuan quickly helped him up.

"The child still needs to be observed after the surgery, so don't thank me today."

Ye Zhen took off her gloves and walked to the wall.

The lead apron hung on the rack, its shoulder straps soaked with sweat.

She raised her hand to press her aching shoulders and neck, then turned and called out to Li Hong.

"Give me the contact information for Hans, the chief engineer at Siemens."

Li Hong was quick; she brought the phone book in less than two minutes.

After the call was connected, Hans's voice came through the receiver.

"Dr. Ye, what kind of problem do you expect me to solve this time?"

Ye Zhen did not exchange pleasantries.

"Could your imaging system simultaneously display the real-time images on the TV in the next room?"

There was a two-second silence on the other end of the phone.

"Normal display is certainly possible."

Ye Zhen pulled out a chair and sat down.

"I need zero latency, no image distortion, and no interference with the host computer."

"The people in the next room need to give instructions via a screen."

The sound of papers turning over came from Hans's side.

"Are you planning to convert the demonstration room into a remote command center?"

"I want to keep the surgeon on the operating table and the attending physician outside the fluoroscopy area."

Hans remained silent for a moment.

"Siemens can provide you with signal distribution and isolation."

Ye Zhen pressed for an answer.

"Who will install it?"

"I'll do it."

Hans's voice was very low.

"You gave me the design of the titanium-magnesium alloy buckle, so I have to come up with something worthy of it."

Give me four days.

After hanging up the phone, Li Hong couldn't hide her excitement.

"Teacher Ye, is Hans really going to fly all the way from Germany just to install a television?"

Ye Zhen turned to the next medical record.

"He's not here to install a television."

"He's here to set up a command center for us."
