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

The moment the clamp was applied, the waveform on the electrocardiogram monitor became a straight line.

The heart stopped.

The timer has started.

Ye Zhen had already taken the scissors from the scrub nurse with her right hand.

The high-powered microscope requested by the Soviet transport medics was not used, nor were the German Aesculap separation forceps on Andrei's list.

She only had a pair of domestically made ophthalmic micro-scissors in her hand.

The handle is twelve centimeters long, and the blade has a 30-degree arc. It's a standard consumable item that costs 1.2 yuan in the hospital's warehouse.

Liu Jianmin's hoarse voice came through the loudspeakers in the observation room.

"She didn't use a microscope?"

Zhou Hai opened his mouth, his Adam's apple bobbing up and down twice, but he couldn't utter a single word.

Andrei's gaze was fixed on the projection screen in the surgical field.

The anterior descending coronary artery, buried in the muscle layer, is completely invisible under the operating light; its color is almost indistinguishable from the surrounding myocardial tissue.

But the tips of the leaves had already begun to separate along some unseen line.

Her technique was completely opposite to what everyone knew about coronary artery separation.

She started from the outer edge of the muscle layer, against the direction of the fibers, and used the back of the scissors to make blunt dissection, pushing the muscle away from the blood vessel wall little by little.

The advantage of this direction is that you always operate on the safe side of the point of force application. The disadvantage is that the distance of each thrust cannot exceed 0.5 millimeters, otherwise it will tear the muscle fibers and rupture the coronary artery below, which is not much thicker than a hair.

Andrei's pen nib broke off unconsciously.

A very faint, crisp sound came from the tip of the pen. Ink splattered on the blank page of the notebook. He glanced down, put the broken pen aside, took a pencil from his jacket pocket, and continued writing.

His hands never stopped, and his mouth never closed; it remained slightly open the entire time.

No one spoke in the observation room; everyone's breathing was suppressed to the shallowest possible.

Ye Zhen, who was on the stage, spoke.

"Attractant".

The nurse handed it over.

"Pull open the left side, another half millimeter."

Ichisuke adjusted the angle of the hook.

Ye Zhen's scissors advanced another step into the muscle layer.

Then she stopped.

The right hand is suspended above the surgical field, remaining motionless.

two seconds.

three seconds.

In the observation room, Ivan, standing behind Andrei, dug his nails into his palm.

Ye Zhen inserted her left index finger into the surgical field, and her fingertip lightly touched the surface of the tissue.

She was feeling it with her fingers.

With eyes no longer in use, one relies entirely on the tactile nerve endings in the skin to identify exactly where the blood vessel beneath the muscle fibers is, how thin its wall is, and which direction it has deviated by a fraction of a degree.

Liu Jianmin's voice came out through clenched teeth, very low.

"Blind separation? In the newborn's coronary artery?"

Zhou Hai shook his head, not in denial, but in disbelief.

Five seconds later, her right hand moved.

The scissors tip followed a trajectory that only her fingertips could perceive, precisely bypassing an unseen fulcrum, the blade turning at a tiny angle, separating the last layer of muscle tissue covering the coronary artery.

A bright red pipe, thinner than a sewing thread, was revealed.

In good condition.

Not a single hair was broken.

Andrei's pencil slipped from his fingers and rolled to the ground, but he didn't pick it up.

His hands were resting on his knees, his fingers interlocked, his knuckles clenched white.

The Soviet transport medic slowly stood up from his corner seat, his legs trembling. He opened and closed his mouth several times, but no sound came out. Finally, he reached out a hand to hold onto the glass wall and slowly bent over.

Ye Zhen's voice on stage was as relaxed as if she were doing ward rounds.

"Coronary artery separation complete, preparing for aortic root reconstruction."

She changed her equipment.

A needle holder, an absorbable suture not much thicker than an eyelash, and a piece of pre-tanned autologous pericardium.

This pericardial membrane was taken from the baby's own pericardium, soaked and solidified in a 0.6% glutaraldehyde solution, and then repeatedly rinsed with hypertonic saline.

There are no artificially synthesized materials.

There is no polyester.

Zero rejection, zero calcification.

She picked up the thin, translucent biofilm, held it up in the air with both hands, and then began to fold it.

It folds four times to form a tubular shape.

Then, use sutures to fix three equidistant recessed structures on the inside of the tube wall.

Three valves.

Handmade.

It took a total of seven minutes from material selection to shaping.

Andrei turned and glanced at Ivan.

Ivan's lips trembled, his hands gripping his knees, and he replied in broken Russian.

"Seven minutes, but it takes us forty minutes to press it with molds in our lab."

Andrei didn't reply, and turned back to stare at the screen.

The pipeline construction has entered the matching stage.

Ye Zhen's needle holder gripped a curved needle the size of a fly's head, and she inserted the needle from the left hand, pushing it through the entire thickness of the vessel wall and the severed end of the blood vessel in a rotating manner.

Parachute-type continuous suture.

First injection.

The second injection.

The third injection.

The spacing between each stitch is no more than one millimeter, and the entry and exit points of each stitch fall 0.8 millimeters directly below the previous stitch.

The stitches are arranged so neatly it looks unreal.

Distal anastomosis completed; proximal anastomosis completed.

The pipeline is connected.

Ye Zhen straightened up and stretched her neck.

"Remove the clamp, restore blood flow, and prepare for rewarming."

The infusion technician operated the machine.

Warm blood was re-infused into the heart that had stopped for forty-one minutes.

Everyone in the observation room had their eyes glued to the monitor screen.

A straight line.

One minute.

A straight line.

Two minutes.

The Soviet military doctor's hands were already trembling.

three minutes.

Andrei's Adam's apple bobbed, his lips were dry and cracked, and he licked his lower lip.

Four minutes.

Liu Jianmin's voice was filled with barely concealed anxiety.

"It's been four minutes, and they still haven't jumped."

five minutes.

straight line.

Someone in the observation room muttered a curse under their breath.

The Soviet transport medic closed his eyes and rested his chin on his chest.

Ye Zhen on the stage did not speak.

Her gaze was not fixed on the monitor.

She was looking at the heart.

The heart, barely larger than a thumbnail, which had been completely upside down and whose passageway had been rebuilt by her own hands, was now submerged in warm blood.

The color is changing from bluish-gray to dark red.

very slow.

But things are changing.

The anesthesiologist's hand was already reaching for the defibrillator switch.

"Dr. Ye, should we prepare for defibrillation?"

"No defibrillation."

Ye Zhen's answer consisted of only three words.

The anesthesiologist's hand froze in mid-air.

"Conduction block, do not use the defibrillator."

She glanced at the completely silent electrocardiogram waveform on the monitor, then looked down at the surgical field again.

Extend your right index and middle fingers together.

My fingertip hovered less than two millimeters above that heart.

She was aiming.

It is aimed at the bifurcation region of the His bundle.

The central hub of the entire cardiac electrical conduction system is a tiny cluster of specialized cells less than 0.5 millimeters wide in the newborn's body.

Liu Jianmin grabbed Zhou Hai's arm, his voice barely audible.

"Is she going to manually tap the pacing device?"
