Ukungasebenzi kwe-valve ye-aortic ibonakala ngokuphulwa kokusebenza kwayo. Umsebenzi oyinhloko we-valve ukukhipha igazi kusuka e-ventricle kwesokunxele kuya e-aorta. Lapha kusetshenziselwa oksijeni, okwathi ngemva kwalokho kuthathwa kuzo zonke izitho. Phakathi kwezinhlangothi ze-cardiac i-valve ye-aortic isendaweni evaliwe, ngaleyo ndlela ivimbela igazi ukuthi lingabuyeli. Ngakho-ke, kungase kuqondwe ukuthi nge-dysfunction ye-valve, ezinye zegazi zingakwazi ukubuyela ezingxenyeni ezingakwesokunxele, okubangela ukuthi izitho ezisele zilahleke igazi futhi zenze inhliziyo isebenze ngokwengeziwe, okuholela emiphumeleni engemuhle ngendlela yokwanda ngobukhulu benhliziyo.
Izimpawu zokuhluleka kwe-valve
Ukuhluleka kwe-valve ye-aortic eziteshini zokuqala ayinayo izimpawu. Lesi sifo sibonakala sekwephuzile kakhulu, lapho inhliziyo isivele ikhuphukile ekukhulekeleni ngokweqile, futhi izindonga zayo seziba mncane kakhulu. Ngalesi sikhathi, isitho sinamandla kakhulu, futhi i-ventricle engakwesokunxele ayisebenzi kahle, okwenza ukuba i-stasis ibe ne-atrium namaphaphu. Yilokho lapho izibonakaliso zokuqala zesifo ziqala ukuvela:
- ubuthakathaka;
- ukukhathala okungekho emthethweni;
- i-arrhythmia;
- i-dyspnea ngisho nasesikhathini sokuthula;
- isiyezi;
- ukulahlekelwa kokwazi.
Kunezibonakaliso ezivelele kakhulu ezivela ngokuzumayo - ukukhululeka nokuvuvukala ku-hypochondrium kanye ne-heart palpitations, okungazibonela yona isiguli.
Ukuhlukaniswa kokuhluleka kwe-valve
Lesi sifo sinezigaba eziningana zokuthuthukiswa, okuhlukile emfanekisweni wezitholampilo kanye nezimpawu. Ngakho:
- Ukungaqiniseki kwe-valve ye-aortic yezinga eli-1 libhekene nokungabikho okuphelele kwezikhalazo zesineke mayelana nempilo nokuhlonza izimpawu ngesikhathi sokuhlolwa. Ngalesi sigaba, lesi sifo singabonakala kuphela ngokuhlolwa okuvamile, ngoba isiguli ngokwakhe asibona isizathu sokubonisana nodokotela.
- Ukungasebenzi kwe-valve ye-aortic yezinga lesibili kubonakala ngokuhluleka kwenhliziyo elandelekile . I-ECG yembula ukwehluleka kwe-ventricle kwesokunxele. Isiguli siqala ukubona izinguquko ezimbi emzimbeni - ngemithwalo encane, i-dyspnoea nokukhathala kuvela.
- Uma i-valve ye-aortic ebangeni lesi-3 ingenalutho, isiguli sizizwa sinezinhlungu, ubuthakathaka obukhulu, nokuphelelwa amandla okungazelelwe. Ngesikhathi esifanayo, u-hypertrophy we-ventricle we-ventricle. Esigabeni esilandelayo, lesi sifo siphuthuma ngokushesha, futhi izinqubo ezidumile zitholakala kakade ezingxenyeni eziningi zangaphakathi, ngoba ukungabi khona kwegazi kuqala ukuphazamisa umsebenzi wabo ngokungalungile.
Ukwelashwa kwe-valent aortic insufficiency
Kungakhathaliseki ukuthi isigaba saleso sifo siphila, ukwelashwa kuqala ngemithi. Isiguli sithatha imithi ezinzisa inhliziyo futhi igcizelele isigqi sayo. Futhi, izidakamizwa zibuyisela ukucindezelwa kwegazi kanye ne-cholesterol.
Kusukela ngesigaba sesithathu sesifo, ukungenelela okuhlinzekwayo kuvame ukusetshenziswa, lapho i-valve ye-aortic ishintshwa khona. Le ndlela yokwelapha iphumelela kakhulu. Inqubo evamile, njenge-valvotomy, ingasetshenziswa ukubuyisela noma ukulungisa i-valve ye-aortic. Phakathi nenqubo, i-catheter ene-inflatable ibhaluni ifakwe enhliziyweni, lokhu kusiza ukuthuthukisa ukugeleza kwegazi. Kodwa le ndlela isetshenziswe ngokungajwayelekile.
