Njira yosokoneza ya endoscopy yachipatala mu matenda a mtima ndi chithandizo chamankhwala

1. Ukadaulo wosokoneza wa kulowererapo kwa mtsempha wamagazi

(1) Intravascular optical coherence tomography (OCT)

Kusokonezeka kwaukadaulo:

10 μm kusamvana: 10 nthawi zomveka bwino kuposa angiography yachikhalidwe (100-200 μ m), ndipo imatha kuzindikira makulidwe a plaque fiber cap caption (<65 μ m imatengedwa kuti ili pachiwopsezo chachikulu chophulika).

Kusanthula kwazithunzi za AI: monga LightLab Imaging system imadziyika yokha zigawo monga calcification ndi lipid core kuti zitsogolere kusankha stent.

Zambiri zachipatala:

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

Kupambana kwaukadaulo:

Catheter ya Boston Scientific Dragonfly OpStar: Single scan imodzi yopeza vascular wall structure (OCT) and plaque burden (IVUS).

Kulondola kwa zisankho zachitetezo cha m'mphepete mwa nthambi za zotupa za bifurcation zasinthidwa kukhala 95%.

2, Kusintha kwa endoscopic mu matenda a mtima

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

Kuyenda kwa opaleshoni ya Mitral valve:

Nthawi yeniyeni ya 3D modeling imasonyeza malo a tendon kupasuka (monga Philips EPIQ CVx system).

Kulondola kwa kugwirizanitsa m'mphepete mwa kuyika kwa MitraClip kwasinthidwa kuchoka pa 70% mpaka 98%.

Mapulogalamu aukadaulo:

Yezerani kukula kwa khomo panthawi ya opaleshoni ya kumanzere kwa atrial occlusion kuti muchepetse kutayikira kotsalira (ndi gawo lochepera 3mm kufika 100%).

(2) Intracardiac Endoscopy (ICE)

Atrial fibrillation radiofrequency ablation:

Catheter ya 8Fr ili ndi endoscope ya 2.9mm (monga AcuNav V) kuti iwonetsetse mwachindunji kudzipatula kwa pulmonary vein.

Kuyerekeza kwa X-ray fluoroscopy: nthawi ya opaleshoni yafupikitsidwa ndi 40%, ndipo kuvulala kwam'mero kunachepetsedwa mpaka ziro.

3, Chiwembu chowonetseratu chowongolera chotengera chachikulu

(1) Aortic Endoscopy (EVIS)

Zowunikira zaukadaulo:

Yang'anani kuphulika kwa interlayer kudzera mu njira yolondolera mawaya pogwiritsa ntchito galasi la ultrafine fiber optic 0.8mm (monga Olympus OFP).

Kafukufuku wa Yunivesite ya Stanford: Kulakwitsa kwa malo a B-mtundu wa sandwich stent kudatsika kuchoka pa 5.2mm mpaka 0.8mm.

Kuwonjezera Fluorescence:

Pafupi ndi infrared endoscopy amawonetsa mitsempha yamkati pambuyo pa jekeseni wa ICG kuti apewe ngozi ya paraplegia.

(2) Kuchotsa venous endoscopic thrombus

Mechanical thrombectomy system:

AngioJet Zelante DVT catheter kuphatikiza ndi endoscopic visualization ili ndi chilolezo chopitilira 90%.

Poyerekeza ndi chithandizo cha thrombolytic, kuchuluka kwa zovuta zamagazi kunatsika kuchokera 12% mpaka 1%.

4, Intelligence ndi Robotic Technology

(1) Magnetic Navigation Endoscopy System

Stereotaxis Genesis MRI:

Magnetic guided endoscopic catheter imamaliza kutembenuka kolondola kwa 1mm kuti athe kuchiza matenda osakhazikika (CTO) a mitsempha yam'mitsempha.

Kuchita bwino kwa opaleshoni kwawonjezeka kuchokera ku 60% mwa njira zachikhalidwe kufika ku 89%.

(2) AI Hemodynamic Prediction

FFR-CT kuphatikiza ndi endoscopy:

Kuwerengera nthawi yeniyeni ya kagawo kakang'ono ka kayendedwe ka magazi kutengera CT ndi data endoscopic kuti tipewe kuyika kwa stent kosafunikira (mtengo wolosera woyipa 98%).

5. Mayendedwe aukadaulo amtsogolo

Endoscope ya molekyulu ya ma cell:

Fluorescent nanoparticles yolunjika ku VCAM-1 imalemba zotupa zoyamba za atherosulinosis.

Degradable vascular endoscope:

Katheta wa polylactic acid amasungunuka atagwira ntchito m'thupi kwa maola 72.

Holographic projection navigation:

Microsoft HoloLens 2 imapanga zithunzi za holographic za mtengo wa mtsempha wamagazi, zomwe zimathandizira kugwira ntchito popanda skrini.

Table Yofananira ya Phindu Lachipatala

Malangizo okonzekera njira

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

Valve Center: Pangani chipinda chopangira ma loboti cha 3D-TEE.

Bungwe lofufuza: Kupanga zokutira zama endoscopic zokonzanso mitsempha yamagazi.

Ukadaulo uwu ukubweretsa kulowererapo kwa mtima mu nthawi yamankhwala olondola kudzera m'njira zitatu zazikulu: kujambula mulingo wa ma cell, maopareshoni akhungu, ndi kukonza magwiridwe antchito a thupi. Zikuyembekezeka kuti pofika chaka cha 2028, 80% yakuchitapo kanthu kwa coronary ikwaniritsa upangiri wapawiri wa AI endoscopic.
