Kulephera kwa valve aortic kumadziwika ndi kuphwanya ntchito yake. Ntchito yaikulu ya valve ndiyo kuchotsa magazi kuchokera kumapeto kwa ventricle kupita ku aorta. Kumeneko umapindula ndi mpweya, kenako umatengedwa ku ziwalo zonse. Pakati pa mapiritsi a mtima, valve ya aortic imakhala yotsekedwa, motero kupewa magazi kuti abwererenso. Choncho, zimatha kumvetsetsa kuti, ngati magaziwa sagwiritsidwe ntchito, magazi ena amatha kubwerera kumanzere, omwe amachititsa kuti ziwalo zina zisawononge magazi ndipo zimapangitsa mtima kugwira ntchito mwakhama, zomwe zimabweretsa mavuto omwe amachititsa kukula kwa mtima.
Zizindikiro za kulephera kwa valve
Kulephera kwa valve ya Aortic mu magawo oyamba alibe zizindikiro. Matendawa amadziwika mochedwa, pamene mtima wakula kale kuchoka kuwonjezereka, ndipo makoma ake afika pochepa. Panthawi imeneyi, limbali lafooka kwambiri, ndipo zotsalira za ventricle sizikugwira ntchito bwino, zimayambitsa stasis mu atrium ndi mapapo. Ndizomwe zizindikiro zoyamba za matenda zimayamba kuonekera:
- kufooka;
- kutopa;
- kukonza;
- dyspnea ngakhale m'malo ozizira;
- chizungulire;
- kutaya chidziwitso.
Pali zizindikiro zooneka bwino zomwe zimabwera mwadzidzidzi - kulemera ndi kutupa mu hypopondrium yolondola komanso mtima wophiphiritsira, zomwe wodwala mwiniwakeyo angazindikire.
Chiwerengero cha kulephera kwa valve
Matendawa ali ndi magawo angapo a chitukuko, omwe amasiyana mu chithunzi ndi zizindikiro. Kotero:
- Kulephera kwa valve ya aortic ya digrii yoyamba ikudziwika ndi kupezeka kwathunthu kwa madandaulo okhudzana ndi thanzi ndikuzindikiritsa zizindikiro panthawi yofufuza. Panthawi imeneyi, matendawa amatha kudziwika ndi kafukufuku wokhazikika, chifukwa wodwala mwiniyo sawona chifukwa chilichonse chofunsira dokotala.
- Kulephera kwa aortic valve ya 2 digiri amadziwika ndi latent mtima kulephera . ECG imavumbula zosavuta mu ventricle ya kumanzere. Wodwala amayamba kuzindikira zolakwika m'thupi - ndi zochepa, dyspnoea ndi kutopa zimawonekera.
- Ngati valve ya aortic ya m'kalasi 3 ilibe, wodwalayo akumva kupweteka, kufooka kwathunthu, ndi kutaya mwadzidzidzi. Pa nthawi yomweyi, kumbuyo kwa ventricle zowonongeka. Pachigawo chotsatira, nthendayi imakula mofulumira, ndipo njira zowonongeka zimapezeka kale mu ziwalo zambiri zamkati, chifukwa kusowa kwa magazi kumayambitsa ntchito yawo molakwika.
Kuchiza kwa valve aortic kusakwanira
Mosasamala kanthu ka siteji ya matenda, mankhwala amayamba ndi mankhwala. Wodwala amatenga mankhwala omwe amatsitsimutsa mitima ndi kuimika nyimbo yake. Komanso, mankhwala osokoneza bongo amabwezeretsa kuthamanga kwa magazi ndi kolesterolo.
Kuyambira ndi siteji yachitatu ya matenda, opaleshoni yopaleshoni imagwiritsidwa ntchito, nthawi yomwe valvato ya aortic imalowetsedwa. Njira imeneyi ndi yothandiza kwambiri. Njira zodabwitsa, monga valvotomy, zingagwiritsidwe ntchito kubwezeretsa kapena kukonzanso valavu ya aortic. Panthawiyi, catheter yokhala ndi galasi yotengera inflatable imalowa mu mtima, izi zimathandiza kusintha magazi. Koma njira iyi imagwiritsidwa ntchito kawirikawiri.
