Tiyeni tiphunzire za Aortic Valve: Chimodzi mwa zipata zofunika kwambiri mumtima mwathu.

Tonsefe timamva phokoso mkati mwa chifuwa chathu lomwe limati "lub-dub...lub-dub..." nthawi zonse, sichoncho? Ndi phokoso la mtima wathu lomwe likugunda. Mtima uwu ndi makina odabwitsa omwe amapopa magazi m'thupi lathu lonse. Koma kuti makinawa agwire ntchito bwino, zitseko zina zazing'ono mkati mwake, kapena ma valve, ziyenera kugwira ntchito bwino. Lero tikambirana za imodzi mwa ma valve ofunikira kwambiri, "Aortic Valve," yomwe imagwira ntchito ngati chipata chachikulu chomwe chimatumiza magazi m'thupi lathu.

Kodi Valavu ya Aortic ndi chiyani?

Mwachidule, valavu ya aorta ndi imodzi mwa mavalavu anayi akuluakulu mumtima mwathu. Taganizirani za mtima wathu ngati nyumba yokhala ndi zipinda zinayi. Timatcha zipinda zinayi izi:

• Atria: Izi ndi zipinda ziwiri zapamwamba. Atrium yakumanja ndi atrium yakumanzere.
• Ma ventricle: Awa ndi zipinda ziwiri zapansi. Ventilaki yakumanja ndi ventricle yakumanzere.

Pamene magazi akuyenda pakati pa zipinda zimenezi, ma valve amenewa amakhalapo kuti aletse magazi kuyenda molakwika. Ma valve amenewa ali ngati zitseko zomwe zimangotseguka mbali imodzi.

Vavu ya msempha wa aorta ili pamalo ofunikira kwambiri. Ndiko kuti, pakati pa ventricle yakumanzere, chipinda chachikulu chomwe chimapopera magazi oyera, okhala ndi mpweya kupita ku thupi lathu lonse, ndi aorta, mtsempha waukulu kwambiri wamagazi womwe umanyamula magazi amenewo m'thupi lonse. Kunena zoona, vavu ya msempha wa aorta iyi ndiye chipata chachikulu chomwe magazi amatuluka mumtima.

Kodi valavu ya aorta imagwira ntchito bwanji? Magazi amayenda mumtima...

Kuti timvetse izi, tiyeni tiwone momwe magazi amayendera mkati mwa mtima. N'zosavuta kwambiri.

1. Choyamba, magazi omwe akhala akugwiritsidwa ntchito m'thupi lathu komanso omwe ali ndi mpweya wochepa amabwera kumanja kwa mtima.

2. Mbali yakumanja imapopera magaziwo kupita ku mapapo. Mapapo amabwezeretsanso mpweya m'magaziwo.

3. Magazi atsopano, oyera, odzaza ndi mpweya, tsopano akubwera kumanzere kwa mtima.

4. Apa ndi pomwe munthu wathu wamkulu, valavu ya msempha, imayamba kugwira ntchito. Pamene ventricle yakumanzere kumbali yakumanzere ya mtima yafupika kwambiri ndikutulutsa magazi, valavu ya msempha imatseguka kwambiri .

5. Kudzera mu valavu yotseguka, magazi okhala ndi mpweya amalowa mu mtsempha wamagazi, komwe magazi amafalikira m'thupi lathu lonse kuyambira kumutu mpaka kumapazi.

6. Magazi akatulutsidwa, valavu ya aorta imatseka nthawi yomweyo . Imatseka kuti magazi omwe alowa mu aorta asatulukirenso mumtima.

Kodi ziwalo za valavu ya aorta ndi ziti?

Mu valavu ya aorta yathanzi komanso yabwinobwino, pali tinthu tating'onoting'ono tating'onoting'ono ta minofu tomwe timatcha kuti "timabuku kapena ma cusps." Mtima ukagunda, tinthu titatuti timatseguka kwambiri kuti magazi alowe, kenako timatsekana mwamphamvu.

Koma anthu ena amabadwa ndi ma valve awiri okha mwa awa. Vutoli limatchedwa bicuspid aortic valve . Ngakhale kuti izi sizimayambitsa mavuto kwa zaka zambiri, nthawi zina pamakhala chiopsezo chochepa cha mavuto a ma valve mtsogolo.

Kodi ndi zinthu ziti zomwe zimakhudza valve ya aorta?

Pakapita nthawi, chifukwa cha matenda, kapena chifukwa cha zifukwa zina zobadwa nazo, valavu ya msempha imatha kusagwira ntchito bwino. Pali mavuto akuluakulu angapo omwe angawonekere.

Kodi pali chithandizo cha vuto la valavu?

Inde, ndithudi. Njira yochizira imadalira mtundu ndi kuopsa kwa matendawa, komanso thanzi la wodwalayo. Nthawi zina, dokotala wanu angakupatseni mankhwala, kulangizani kuti musinthe moyo wanu, ndikukuyang'anirani nthawi zonse.

Komabe, ngati valavu yawonongeka kwambiri, opaleshoni ingafunike. Masiku ano, pali njira zambiri zamakono zochitira izi.

Njira yatsopano yotchedwa TAVR

Imodzi mwa njira zapaderazi ndi Transcatheter Aortic Valve Replacement (TAVR) .

Izi zimaphatikizapo njira yaying'ono kwambiri, osati opaleshoni yayikulu yomwe imaphatikizapo kutsegula chifuwa.

• Dokotala adzaika catheter , chubu chopyapyala komanso chosinthasintha, kudzera mu mtsempha wamagazi womwe uli mu mwendo kapena pachifuwa chanu mpaka kumtima kwanu.
• Mkati mwa chubu ichi, valavu yatsopano yopangira imatumizidwa kumtima.
• Vavu yatsopano imayikidwa pamalo omwewo monga valavu yakale, yowonongeka. Nthawi zina, imadzazidwa ndi chinthu chonga baluni yaying'ono ndikuyikidwa pamalo ake.
• Kenako chubucho chimachotsedwa.

Njirayi ndi yoopsa pang'ono ndipo imachira mwachangu kuposa opaleshoni yachikhalidwe yotsegula mtima. Komabe, si yoyenera aliyense. Dokotala wanu adzasankha chithandizo chomwe chili chabwino kwa inu.

Kodi ndingatani kuti valve yanga ya aortic ndi mtima wanga zikhale zathanzi?

Mtima wathu ndi chinthu chomwe tiyenera kuchisamalira bwino. Kukhala ndi moyo wathanzi kungathandize kuti mtima wathu ukhale wathanzi, komanso kuti mtima wonse ukhale wathanzi.

• Khalani ndi kulemera kwabwino: Yesetsani kukhala ndi kulemera kwabwino kwa thupi komwe kukugwirizana ndi kutalika kwanu ndi msinkhu wanu.
• Idyani zakudya zopatsa thanzi pamtima: Idyani mchere wochepa, mafuta, ndi shuga, ndipo onjezerani ndiwo zamasamba, zipatso, zitsamba, ndi tirigu wonse wa ulusi muzakudya zanu.
• Kuchita Maseŵera Olimbitsa Thupi: Chitani masewera olimbitsa thupi omwe amakupangitsani thukuta, masiku osachepera 5 pa sabata, kwa mphindi zosachepera 30 patsiku. Kuyenda, kuthamanga, kapena kusambira ndi njira zabwino.
• Pewani kupsinjika maganizo: Pumulani maganizo anu kudzera mu zinthu monga kusinkhasinkha, yoga, kulankhula ndi anzanu, ndi kuchita zinthu zosangalatsa.
• Pewani kusuta fodya kotheratu: Kusuta fodya ndi mdani wamkulu wa mtima. Siyani chizolowezichi lero.

Ngati mukukayikira matenda a mtima, kupweteka pachifuwa, kapena zizindikiro monga kuvutika kupuma, musachedwe ndipo pitani kwa dokotala nthawi yomweyo. Iye adzachita mayeso ofunikira ndikukupatsani upangiri wofunikira.
