ដំណោះស្រាយរំខាននៃការថតឆ្លុះផ្នែកវេជ្ជសាស្រ្ដក្នុងការធ្វើរោគវិនិច្ឆ័យ និងការព្យាបាល អន្តរាគមន៍សរសៃឈាមបេះដូង

1、 Disruptive technology of coronary artery intervention

(1) Intravascular optical coherence tomography (OCT)

ការរំខានផ្នែកបច្ចេកវិទ្យា៖

10 μ m resolution: 10 times clearer than traditional angiography (100-200 μ m), and can identify vulnerable plaque fiber cap thickness (<65 μ m is considered high-risk for rupture).

AI plaque analysis: such as LightLab Imaging system automatically classifies components such as calcification and lipid core to guide stent selection.

ទិន្នន័យគ្លីនិក៖

(2) Intravascular ultrasound optical fusion imaging (IVUS-OCT)

របកគំហើញបច្ចេកវិទ្យា៖

Boston Scientific Dragonfly OpStar catheter: Single scan simultaneous acquisition of vascular wall structure (OCT) and plaque burden (IVUS).

The accuracy of edge branch protection decision-making for bifurcation lesions has been improved to 95%.

2、 The endoscopic revolution in structural heart disease

(1) Transesophageal endoscopic ultrasonography (3D-TEE)

Mitral valve repair surgery navigation:

Real time 3D modeling displays the location of tendon rupture (such as the Philips EPIQ CVx system).

The accuracy of aligning the edges during MitraClip implantation has been improved from 70% to 98%.

កម្មវិធីច្នៃប្រឌិត៖

Measure the diameter of the opening during left atrial appendage occlusion surgery to reduce residual leakage (with a proportion of less than 3mm reaching 100%).

(2) Intracardiac Endoscopy (ICE)

Atrial fibrillation radiofrequency ablation:

The 8Fr catheter is equipped with a 2.9mm endoscope (such as AcuNav V) for direct visualization of pulmonary vein potential isolation.

Comparison of X-ray fluoroscopy: surgery time shortened by 40%, and esophageal injury was reduced to zero.

3、 Direct visualization scheme for large vessel intervention

(1) Aortic Endoscopy (EVIS)

គំនួសពណ៌បច្ចេកទេស៖

Observe the interlayer rupture through a guide wire channel using a 0.8mm ultrafine fiber optic mirror (such as Olympus OFP).

Stanford University research: The positioning error of B-type sandwich stent decreased from 5.2mm to 0.8mm.

Fluorescence enhancement:

Near infrared endoscopy shows intercostal arteries after ICG injection to avoid the risk of paraplegia.

(2) Venous endoscopic thrombus removal

Mechanical thrombectomy system:

AngioJet Zelante DVT catheter combined with endoscopic visualization has a clearance rate of over 90%.

Compared to thrombolytic therapy, the incidence of bleeding complications decreased from 12% to 1%.

4、 Intelligence and Robotics Technology

(1) Magnetic Navigation Endoscopy System

Stereotaxis Genesis RMN：

Magnetic guided endoscopic catheter completes a 1mm precision turn for the treatment of chronic total occlusion (CTO) of coronary arteries.

The success rate of surgery has increased from 60% in traditional methods to 89%.

(2) AI Hemodynamic Prediction

FFR-CT combined with endoscopy:

Real time calculation of blood flow reserve fraction based on CT and endoscopic data to avoid unnecessary stent implantation (negative predictive value 98%).

5. ទិសដៅបច្ចេកវិទ្យានាពេលអនាគត

ការឆ្លុះរូបភាពម៉ូលេគុល៖

Fluorescent nanoparticles targeting VCAM-1 label early atherosclerosis lesions.

Degradable vascular endoscope:

The polylactic acid material catheter dissolves after working in the body for 72 hours.

Holographic projection navigation:

Microsoft HoloLens 2 projects holographic images of the coronary artery tree, enabling screenless operation.

តារាងប្រៀបធៀបអត្ថប្រយោជន៍គ្លីនិក

ការណែនាំផ្លូវអនុវត្ត

Chest Pain Center: Standard OCT+IVUS composite imaging catheter.

Valve Center: Construct a 3D-TEE robot hybrid operating room.

Research institution: Developing endoscopic coatings for vascular endothelial repair.

These technologies are bringing cardiovascular intervention into the era of precision medicine through three major breakthroughs: cell level imaging, zero blind spot operation, and physiological function repair. It is expected that by 2028, 80% of coronary interventions will achieve AI endoscopic dual guidance.
