Ukungakwazi ukusebenza kwe-valve ye-mitral ingenye yezinhlobo zezifo, okubizwa ngegama lesifo senhliziyo. Kulokhu, imisebenzi ye-valve mitral iphulwa, futhi ayigcinanga ngokuphelele, okwenza igazi lingene e-atrium lesokunxele, kuyilapho ivolumu yayo ikhuphuka, okuyinto engeyona inqubo enhle yesistimu ye-cardiovascular kanye nayo yonke inyama yonke.
Izimbangela zesifo
Kusukela kuleso sizathu kuncike ekutheni ukungakwazi ukusebenza kwe-valve mitral kuzokhula. Kunezici eziningana ezithonya ukubonakala kwesifo:
Isifo se-Congenital yisisusa esibangelwa kaningi kunabanye. Lokhu kungenxa yokuthi ngesikhathi sokukhulelwa, ezinye izici ezimbi (ukutheleleka, ukucindezeleka, imvelo embi, imisebe, njll) zathonya impilo yomama esikhathini esizayo. Ukungakwazi ukusebenza kwe-valve mitral kungabangela izinhlobo eziningana:
- ukuchithwa kwe-myxomatous;
- izimo eziphuthumayo ngesakhiwo se-valve mitral;
- isici sesakhiwo sezintambo (izintambo).
2. Izifo ezitholakalayo zihlotshaniswa nezinguquko ezithombeni ze-valve. Lokhu kungabangela izici ezilandelayo:
- i-rheumatism;
- ukuthukuthela okuvaliwe kwenhliziyo;
- i-endocarditis yokuphefumula ;
- ukungenelela kokuhlinzwa ekwelapheni kwe- mitral stenosis .
Izimbangela ezitholakalayo ezingahlotshaniswa nezinguquko kumaphuzu we-valve. Lokhu kufaka phakathi
- izinyembezi zezintambo ezinamathele emisipha emasipha enhliziyweni;
- ukunqotshwa kwemisipha yamapill;
- Ukwandiswa kwendandatho encane ezungeze izindonga zenhliziyo, okuthiwa i-ring fibrous.
Isizathu sokugcina sokuhluleka kwe-valve mitral kungumphumela wokuvuvukala kwemisipha yenhliziyo, ukwanda kwenhliziyo, noma ukushintsha ithoni yemisipha yangaphakathi yenhliziyo.
Izimpawu zokungasebenzi kahle kwe-valve mitral
Isibonakaliso sokuqala sokubonakaliswa kwe-valve ye-mitral kungukuphulwa kwenhliziyo, okufaka ukucindezeleka kokuphefumula. Ngezinga elikhulu, lokhu kubonakala ngaphansi kwemithwalo yemvelo, hhayi ngisho nezinkulu. Uma isiguli sizwa ukuphazamiseka kwesigqi senhliziyo ekuphumuleni, isifo siqhubeka. Futhi, kukhona ukukhathala okusheshayo, ukuvuvukala nobuhlungu endaweni ephezulu yesigcawu, okubangelwa ukwanda kwesibindi. Isibonakaliso esingenalindelekile sokungakwazi ukusebenza kwe-valve mitral ukukhwehlela owomile nokukhipha.
Phakathi kwezimpawu ezisobala ezibonisa ngokuqondile isifo senhliziyo esibi, inothi:
- i-cardialgia (ukukhala nokugaya, ukuphindaphinda kancane - ubuhlungu obunzima esifundeni senhliziyo);
- ukunqunywa kwamalungu angaphansi.
Ukwelashwa kwesifo
Indlela yokwelashwa kwe-mitral valve insufficiency ixhomeke esiteji lapho lesi sifo sitholakala khona. Esigabeni sokuqala, ukwelashwa kwezidakamizwa kwenziwa, okwesibili nangesithathu - ukuhlinzeka. Izigaba zesine nesesihlanu zibalulekile, futhi isimo sesiguli asizinzile, ngakho-ke abajwayele ukuvula ukuhlinzwa.
Ekusebenzeni, umsebenzi wokuvala i-mitral valve ubuyiselwe. Ukuze wenze lokhu, unciphisa indandatho enomshini ngekhawu elikhethekile eliqinile lokusekela. Uma kwenzeka ukubalwa kanye ne-fibrosis, i-valve ye-biological noma ye-mechanical ye-valve ifakiwe. Isikhathi sokuvuselelwa ngemuva kokusebenza silingana nesimo sesiguli. Lokhu futhi kusekelwe odokotela abaya kulo, ebeka izinqubo kanye namalungiselelo.
Ngakho-ke, kungase kuqaphele ukuthi ukungakwazi ukusebenza kwe-valve mitral kuyinkinga enzima okuyinto enzima ukuyiphatha ngezigaba sesibili kuya kwelesihlanu, ngakho-ke, ngezibonakaliso zokuqala, ngisho nakude, udokotela kufanele abonisane ngokushesha, ngoba ukulinganisela okulinganiselayo nokungalingani kwe-valve mitral kulula kakhulu ukwelapha .
