Isisombululo esiphazamisayo se-endoscopy yonyango kwi-cardiovascular intervention diagnostic and treatment

I-1, iteknoloji ephazamisayo yokungenelela kwe-coronary artery

(1) I-intravascular optical coherence tomography (OCT)

Ukuphazamiseka kwezobuchwepheshe:

Isisombululo se-10 μ m: amaxesha angama-10 acace ngakumbi kune-angiography yendabuko (i-100-200 μ m), kwaye inokuchonga ubukhulu be-plaque ye-fiber cap ye-plaque (<65 μ m ithathwa njengengozi enkulu yokuphuka).

Uhlalutyo lwe-plaque ye-AI: njenge-LightLab Imaging system ihlela ngokuzenzekelayo amacandelo afana nokubala kunye ne-lipid core ukukhokela ukhetho lwe-stent.

Idatha yonyango:

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

Impumelelo yetekhnoloji:

I-Boston Scientific Dragonfly OpStar catheter: Ukuskena okukodwa kunye nokufunyanwa kwesakhiwo sodonga lwe-vascular (OCT) kunye nomthwalo we-plaque (IVUS).

Ukuchaneka kokwenziwa kwezigqibo zokhuselo lwesebe kwizilonda ze-bifurcation kuphuculwe ukuya kuma-95%.

I-2, i-endoscopic revolution kwi-structural heart disease

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

Ukukhangela utyando lokulungisa ivalve yeMitral:

Ixesha langempela imodeli ye-3D ibonisa indawo yokuphuka kwe-tendon (njengenkqubo ye-Philips EPIQ CVx).

Ukuchaneka kokulungelelanisa imida ngexesha lokufakelwa kwe-MitraClip kuphuculwe ukusuka kwi-70% ukuya kwi-98%.

Ukusetyenziswa okutsha:

Ukulinganisa i-diameter yokuvula ngexesha lotyando lokuvala i-atrial ekhohlo ukunciphisa ukuvuza okushiyekileyo (kunye nomlinganiselo ongaphantsi kwe-3mm ukuya kwi-100%).

(2) I-Intracardiac Endoscopy (ICE)

I-Atrial fibrillation radiofrequency ablation:

I-8Fr catheter ixhotyiswe nge-endoscope eyi-2.9mm (efana ne-AcuNav V) yokujonga ngokuthe ngqo kwe-pulmonary vein enokwenzeka ukuba yodwa.

Ukuthelekiswa kwe-X-ray fluoroscopy: ixesha lotyando lifutshane nge-40%, kunye nokulimala kwe-esophageal kwancitshiswa ukuya kwi-zero.

3, Iskimu sokujonga ngokuthe ngqo kungenelelo olukhulu lwenqanawa

(1) I-Aortic Endoscopy (EVIS)

Amagqabantshintshi obugcisa:

Jonga ukugqabhuka kwe interlayer ngomjelo wocingo wesikhokelo usebenzisa i-0.8mm ultrafine fibre optic mirror (efana ne-Olympus OFP).

Uphando lweYunivesithi yaseStanford: Impazamo yokubeka uhlobo lwe-B-sandwich stent yehlile ukusuka kwi-5.2mm ukuya kwi-0.8mm.

Ukwandiswa kweFluorescence:

I-endoscopy ekufutshane ne-infrared ibonisa i-intercostal arteries emva kwesitofu se-ICG ukuphepha umngcipheko we-paraplegia.

(2) Ukususwa kwe-thrombus ye-venous endoscopic

Inkqubo ye-thrombectomy yoomatshini:

I-AngioJet Zelante DVT catheter idityaniswe ne-endoscopic visualization inezinga lokucoceka elingaphezulu kwe-90%.

Xa kuthelekiswa nonyango lwe-thrombolytic, iziganeko zokuphuma kwegazi ziyancipha ukusuka kwi-12% ukuya kwi-1%.

4, Ubukrelekrele kunye neTekhnoloji yeRobhothi

(1) I-Magnetic Navigation Endoscopy System

I-Stereotaxis yeGenesis MRI:

I-Magnetic guided endoscopic catheter igqiba ukujika okuchanekileyo kwe-1mm kunyango lwe-CTO) ye-coronary arteries.

Izinga lokuphumelela lotyando liye landa ukusuka kwi-60% kwiindlela zendabuko ukuya kwi-89%.

(2) I-AI Hemodynamic Prediction

I-FFR-CT idityaniswe ne-endoscopy:

Ubalo lwexesha langempela lokuhamba kwegazi kwiqhekeza elisekelwe kwi-CT kunye nedatha ye-endoscopic ukuphepha ukufakelwa kwe-stent okungafunekiyo (ixabiso elibi lokuxela kwangaphambili i-98%).

5. Izalathiso zobuchwepheshe bexesha elizayo

I-endoscopy ye-molecular imaging:

I-Fluorescent nanoparticles ejolise kwi-VCAM-1 ilebula ekuqaleni kwezilonda ze-atherosclerosis.

I-endoscope yemithambo yemithambo:

I-catheter ye-polylactic acid iyancibilika emva kokusebenza emzimbeni iiyure ezingama-72.

IHolographic yokujonga ukukhangela:

I-Microsoft HoloLens 2 iprojekthi yemifanekiso eqingqiweyo yomthi we-coronary artery, evumela ukusebenza ngaphandle kwesikrini.

Itheyibhile yokuthelekisa iNzuzo yezonyango

Iingcebiso zendlela yokuphumeza

Iziko leentlungu zesifuba: I-OCT esemgangathweni + IVUS i-catheter yokucinga edibeneyo.

Iziko leValve: Yakha i-3D-TEE irobhothi elixubileyo kwigumbi lokusebenza.

Iziko lophando: Ukuphuhlisa iingubo ze-endoscopic zokulungiswa kwe-vascular endothelial.

Obu bugcisa buzisa ungenelelo lwentliziyo kwixesha leyeza elichanekile ngokusebenzisa iimpumelelo ezintathu eziphambili: umfanekiso wenqanaba leseli, uqhaqho olungaboniyo, kunye nokulungiswa komsebenzi womzimba. Kulindeleke ukuba ngo-2028, i-80% yongenelelo lwe-coronary iya kufezekisa i-AI endoscopic isikhokelo esimbini.
