Tiyeni tiphunzire za valavu ya aorta yomwe ili mumtima mwanu. Tiyeni tikambirane izi mosavuta!

Kodi munayamba mwadzifunsapo ngati pali ziwalo zazing'ono, zonga chipata mkati mwa mtima wanu zomwe zimatseguka ndi kutsekedwa panthawi yoyenera kuti zilamulire kuyenda kwa magazi? Gawo limodzi lofunika kwambiri ndi valavu ya aorta . Lero tikambirana za gawo laling'onoli, koma lamphamvu kwambiri la mtima wathu. Musadandaule, ndikukufotokozerani m'njira yosavuta yomwe mungamvetse.

Kodi ma valve omwe ali mumtima mwathu ndi otani?

Chabwino, choyamba tiyeni tiwone zomwe ma valve a mtima awa ali. Tangoganizani mtima wanu uli ngati nyumba yokhala ndi zipinda zinayi. Zipinda ziwiri pamwamba ndi zipinda ziwiri pansi.

• Timatcha zipinda ziwiri zapamwamba izi kuti ' atria' .
• Timatcha zipinda ziwiri zomwe zili pansi pa mtima kuti ndi ma ventricle .

Tsopano, pakati pa zipinda izi, pakati pa mitsempha ikuluikulu yamagazi yomwe imanyamula magazi kuchokera mumtima, pali ziwalo zomwe zimagwira ntchito ngati zipata. Ndicho chimene timatcha ma valve amtima . Ma valve awa amapangidwa ndi ma flaps ang'onoang'ono otchedwa 'timabuku' kapena 'cusps'. Nthawi iliyonse mtima ukagunda, ma flaps awa amatseguka ndi kutsekedwa panthawi yoyenera. Izi zimathandiza kuti magazi aziyenda mbali imodzi, monga magalimoto omwe ali mumsewu akupita mbali imodzi.

Ndiye, kodi valve yotchedwa aortic valve iyi imagwira ntchito bwanji?

Chabwino, valavu iyi ya aorta yomwe tikukamba pano ndi imodzi mwa mavalavu anayi akuluakulu mumtima mwanu. Ndi yapadera kwambiri. Kodi mukudziwa kuti ndi chiyani? Ndi kulumikizana pakati pa chipinda chachikulu chopopera magazi kumbali yakumanzere ya mtima wanu, ventricle yakumanzere , ndi mtsempha waukulu kwambiri wamagazi womwe umanyamula magazi oyera kupita ku thupi lanu lonse, aorta .

Mwachidule, valavu ya aorta ili ngati galu wanzeru wolondera.

1. Imatsegula : kulola magazi okhala ndi mpweya kupita ku aorta kuchokera ku ventricle yakumanzere.

2. Imatseka : Magazi akalowa mu mtsempha wamagazi, amatseka mwachangu. N’chifukwa chiyani imatseka? Kuletsa magazi kuti asatulukenso m’njira yolakwika, kutanthauza kuti, kuchokera mu mtsempha wamagazi kupita ku ventricle yakumanzere. Zili ngati kutseka pompo yamadzi.

Valavu ya mtsempha wamagazi iyi ndi imodzi mwa mitundu iwiri ya mavavu otchedwa `` semilunar valves.'' Dzinali limachokera ku mawonekedwe a timapepala ta vavu, tomwe timafanana ndi mwezi wooneka ngati mwezi. Kodi si wokongola?

Kodi valavu ya aorta imagwira ntchito bwanji ndi ziwalo zina za mtima?

Taganizirani izi motere: Kuyenda kwa magazi m'thupi lathu kuli ngati njira yovuta ya misewu. Valavu ya aorta imagwira ntchito yayikulu pakusunga dongosololi bwino. Umu ndi momwe limagwirira ntchito, mwadongosolo kwambiri:

• Gawo loyamba: Mbali yakumanja ya mtima wanu imasonkhanitsa magazi opanda mpweya (omwe amatchedwanso "magazi onyansa") omwe akhala akuyenda m'thupi lanu lonse ndikupopera kupita ku mapapo.
• Gawo lachiwiri: Kenako, mapapu anu amawonjezera mpweya watsopano m'magazi amenewo, n’kuwasandutsa “magazi oyera,” n’kuwatumizanso kumanzere kwa mtima.
• Gawo Lachitatu: Tsopano pakubwera protagonist wathu, valavu ya mtsempha wamagazi.Imayamba kugwira ntchito. Imatseguka, zomwe zimathandiza kuti magazi atsopano, okhala ndi mpweya wochokera kumanzere kwa mtima (ndiko kuti, ventricle yakumanzere) alowe mu aorta.
• Gawo Lachinayi: Pomaliza, mtsempha wanu wamagazi umapopa magazi ochulukirapo a okosijeni m'thupi lanu lonse, kuyambira kumutu mpaka kumapazi. Apa ndi pamene selo lililonse m'thupi lanu limalandira mpweya womwe limafunikira kuti likhale ndi moyo.

Kodi mukumvetsa momwe njira imeneyi ilili yodabwitsa?

Kodi valavu ya aorta ili kuti? Kodi imapangidwa kuti?

Valavu yanu ya aorta ili pakati pa ventricle yakumanzere ndi aorta . Kunena zoona, ngati muyang'ana mtima wanu molunjika, uli pakati pa mtima.

Vavu iyi imapangidwa ndi zigawo zitatu zopangidwa ndi chinthu cholimba koma chosinthasintha chotchedwa collagen . Izi zimatchedwanso timabuku kapena cusps. Mu mtima wathanzi, timabuku titatuti timagwira ntchito mogwirizana bwino:

• Imatseguka bwino ikafunika kutuluka magazi.
• Imatseka bwino kwambiri ngati pakufunika kuletsa magazi kuti asabwererenso.

Kodi valavu ya Bicuspid Aortic Valve ndi chiyani?

Kawirikawiri, aliyense amakhala ndi ma cusps atatu mu valavu yawo ya aortic. Komabe, anthu ena amabadwa ndi ma cusps awiri okha m'malo mwa atatu. Ndicho chimene timachitcha bicuspid aortic valve . 'bi' amatanthauza awiri. Kukhala ndi ma cusps awiri okha nthawi zina kungapangitse kuti magazi aziyenda bwino komanso mavuto ena a mtima. Koma si aliyense amene amatero.

Kodi ndi zinthu ziti zomwe zimakhudza valve ya aorta?

Mwatsoka, matenda ena a mtima angakhudze valavu yathu yofunika kwambiri ya mtsempha wamagazi. Ena ndi obadwa nawo, zomwe zikutanthauza kuti amapezeka pobadwa. Ena amatha kukula pambuyo pake, mwina chifukwa cha matenda, kuwonongeka kwa mtima, monga matenda a mtima , kapena kusintha komwe kumachitika ndi ukalamba.

Nazi zina mwa zinthu zazikuluzikulu izi:

• Kubwerera kwa valavu ya mtsempha wamagazi : Apa ndi pamene valavu siitseka bwino, zomwe zimapangitsa kuti magazi ena omwe amaponyedwa mu mtsempha wamagazi atulukirenso mu ventricle yakumanzere. Zili ngati chitseko chikapanda kutseka bwino, chinthu chomwe chinakankhidwira kunja chimabwereranso. Izi zimapangitsa mtima kugwira ntchito molimbika.
• Kutsekeka kwa valavu ya mtsempha wamagazi : Apa ndi pamene valavu ya mtsempha wamagazi imachepa kapena kukhuthala. Vavuyo siitseguka bwino, zomwe zimachepetsa kuchuluka kwa magazi omwe angadutsemo. Taganizirani ngati chitoliro chamadzi chomwe chimatsekedwa pakati, zomwe zimachepetsa kuchuluka kwa madzi omwe angadutse. Izi zimayikanso kupsinjika kwakukulu pamtima.
• Valavu ya aorta ya bicuspid(`Bicuspid aortic valve`): Monga tanenera kale, pali ma valve awiri okha. Vutoli limayambitsa `stenosis` kapena `regurgitation` pakapita nthawi.
• Endocarditis : Iyi ndi matenda oopsa kwambiri. Pachifukwa ichi, mkati mwa ma valve ndi zipinda za mtima (zotchedwa endocardium ) mumatupa, zomwe zikutanthauza kuti zimatupa ndikukhala ndi kachilomboka. Ngati izi sizichiritsidwa mwachangu, ma valve amatha kuwonongeka.

Kodi Transcatheter Aortic Valve Replacement (TAVR) iyi ndi chiyani?

Tsopano, onani, nthawi zina ngati valavu ya aortic yawonongeka kwambiri moti singakonzedwenso, kapena ngati yakula kwambiri ngati stenosis, valavuyo iyenera kusinthidwa. Kale, iyi ikanakhala opaleshoni yayikulu, opaleshoni yotseguka. Ndi nkhani yaikulu.

Koma tsopano, chifukwa cha kupita patsogolo kwa sayansi ya zamankhwala, pali njira yotchedwa Transcatheter Aortic Valve Replacement (TAVR). Nthawi zina imatchedwanso Transcatheter Aortic Valve Implantation (TAVI). Uku ndi kupita patsogolo kodabwitsa kwambiri.

Izi zimaphatikizapo kusintha valavu kudzera m'bowo laling'ono, popanda kudula kwakukulu. Imeneyi ingakhale njira yabwino yothandizira ngati muli ndi vuto la aortic valve stenosis , makamaka ngati ndinu okalamba kapena simungathe kupirira opaleshoni yayikulu.

Umu ndi momwe mungachitire izi, mwachidule:

• Dokotala amaika catheter (chubu chopyapyala, chosinthasintha, komanso chopanda kanthu) mu mtsempha wamagazi (mtsempha kapena mtsempha wamagazi) womwe uli mu mwendo wanu (nthawi zambiri m'mimba mwanu) kapena pachifuwa.
• Poyang'ana makina apadera a X-ray, catheter imatsogozedwa mosamala ku valavu ya aorta ya mtima.
• Valavu yatsopano yopangira (iyi ndi valavu yolumikizidwa pa chimango chapadera chachitsulo) imalowetsedwa mumtima kudzera mu catheter imeneyo ndikukhazikika m'malo mwake mkati mwa valavu yakale, yodwala.
• Nthawi zina baluni yaying'ono imagwiritsidwa ntchito kupopera valavu yatsopanoyi, kapena mavalavu ena amapangidwira kuti adzipopera okha.
• Valavu yatsopano ikayikidwa, catheter imachotsedwa.

Njira imeneyi imatanthauza kuti munthu asakhale kuchipatala nthawi yayitali, asamachire, komanso asamavulale kwambiri. Ichi ndi chinthu chabwino kwambiri, eti?

Kodi tingatani kuti valavu yathu ya aortic ikhale yathanzi?

Pali zinthu zambiri zomwe tingachite kuti mtima wathu wonse ukhale wathanzi, osati mtima wathu wokha. Izi ndi zinthu zosavuta, koma zofunika kwambiri zomwe tingaziphatikize m'miyoyo yathu ya tsiku ndi tsiku:

• Khalani ndi kulemera koyenera malinga ndi mtundu wa thupi lanu, jenda, komanso zaka zanu. Kunenepa kwambiri ndi vuto lalikulu pamtima.
• Idyani zakudya zopatsa thanzi pamtima. Izi zikutanthauza:
• Chepetsani mchere (sodium).
• Chepetsani zakudya zokhala ndi shuga wambiri ndi mafuta ambiri.
• Onjezerani zipatso zatsopano, ndiwo zamasamba, ndi tirigu wathunthu (monga mpunga wa bulauni, buckwheat, ndi oats) muzakudya zanu.
• Idyani nsomba (makamaka nsomba zamafuta monga salimoni ndi mackerel) kawiri kapena katatu pa sabata.
• Kuchita masewera olimbitsa thupi. Kuchita masewera olimbitsa thupi kwa mphindi zosachepera 30 patsiku, masiku asanu mpaka asanu ndi awiri pa sabata. Mutha kuchita zinthu monga kuyenda mwachangu, kuthamanga, kusambira, kapena kukwera njinga. Sankhani chinthu chomwe mumakonda.
• Sinthani kupsinjika maganizo. Kupsinjika maganizo kwambiri sikwabwino pamtima. Chepetsani kupsinjika maganizo m'njira zabwino, monga kusinkhasinkha, kuchita yoga, kuchita zinthu zomwe mumakonda, komanso kukhala ndi nthawi ndi anzanu komanso abale anu.
• Ngati mukusuta, siyani lero. Kusuta ndi mdani wamkulu wa mtima.
• Chepetsani kumwa mowa.
• Ngati muli ndi matenda ena monga matenda a shuga, kuthamanga kwa magazi, kapena cholesterol, samalani bwino. Tsatirani malangizo a dokotala wanu mosamala.

Kodi ndiyenera kufunsa dokotala wanga chiyani za valve yanga ya aortic?

Ngati muli ndi nkhawa kapena mavuto ndi mtima wanu, makamaka valavu yanu ya mtsempha wamagazi, kapena ngati muli ndi zizindikiro monga kupweteka pachifuwa, kupuma movutikira, kapena kutopa pafupipafupi, muyenera kuwona dokotala wanu ndikukambirana za izi. Nazi mafunso ena omwe mungafunse dokotala wanu:

• Kodi ndingadziwe bwanji ngati ma valve a mtima wanga akugwira ntchito bwino? Ndi mayeso ati omwe angachitike kuti awone?
• Ngati ndikuganiza kuti ndili ndi vuto ndi valavu yanga ya aorta, kodi chifukwa chake chachikulu ndi chiyani?
• Kutengera ndi zizindikiro zanga, ndi njira ziti zochiritsira zomwe ndili nazo?
• Kodi ndiyenera kuchitidwa opaleshoni ya valve ya aortic kapena china chake chonga TAVR?
• Ndi kusintha kotani komwe ndiyenera kuchita pa moyo wanga kuti ndikhale ndi thanzi labwino la mtima wanga?
• Ngati wina m'banja langa wakhala ndi matenda a mtima, kodi inenso ndili pachiwopsezo?

Musachite mantha, funsani mafunso onse omwe muli nawo. Dokotala ali pano kuti akuthandizeni.

Pomaliza, zinthu zoti muzikumbukira

Chabwino, kuchokera pa zomwe takambirana lero, ndikukhulupirira kuti mwamvetsetsa bwino za valavu ya aorta.

Kumbukirani, valavu ya mtsempha wamagazi ndi gawo lofunika kwambiri komanso lofunika kwambiri la mtima wanu. Bola ngati ikugwira ntchito bwino, magazi opatsa moyo m'thupi lanu lonse amakhala abwino.

N’zoona kuti matenda ena a mtima angakhudze valavu ya msempha. Komabe, ndi mankhwala apamwamba amakono, matenda ambiriwa amatha kuchiritsidwa bwino. Ngati zizindikiro zanu zili zazikulu, dokotala wanu angakulangizeni opaleshoni yokonza kapena kusintha valavu ya msempha, kapena njira monga TAVR.

Komabe, ndikofunikira kwambiri kutsatira moyo wathanzi kuti muwongolere thanzi la mtima wanu. Ngati muli ndi mafunso okhudza thanzi la mtima wanu, musaope kulankhula ndi dokotala wanu, chabwino? Kusamalira mtima wanu ndi imodzi mwa mphatso zazikulu zomwe mungadzipatse nokha!

Valavu ya mtsempha wamagazi , valavu yamtima, mtima, kuyenda kwa magazi, matenda amtima, TAVR, thanzi la mtima
