I-Mitral valve insufficiency

Ukungaqiniseki kwe-Mitral valve kubangelwa ukukhubazeka emsebenzini wokuvala. Kukhona ukwephulwa okunjalo ngenxa yokuguqulwa kwamagagasi, njengombandela, wezinto eziphathekayo. Ithonya ekuthuthukiseni lesi sifo lithinteka ukulimala kwezakhi ezincane ze-valvular, kanye nokuphazamiseka kobuqotho bezici ezithile ze-valve. Okubaluleke nakakhulu ukuqhutshwa kwendandatho ensimbi. Konke lokhu okungenhla kuholele ekupheleni kwenhlangano yokubuyela emuva kwengxenye yegazi kusukela e-ventricle systemole kuya kwe-atrium engakwesobunxele, okubangela ukwehla ekuhambeni kweminithi kanye nokuthuthukiswa komfutho wegazi ophezulu wamaphaphu.

Ukungasebenzi kwe- valve ye- mitral yohlu olulodwa olukude lisho izinto ezivame kakhulu. Lesi simo sibonakala ngamaphesenti amabili kuphela azo zonke izimo. Njengomthetho, ukuphazanyiswa komsebenzi wokuvala kuhambisana nesimo se-mitral valve noma amaphutha enhliziyo e-aortic.

Lesi simo singasebenza noma sokwemvelo.

Esikhathini sokuqala, ukungakwazi ukusebenza kwe- valve mitral kukhula nokwandiswa kwendawo ye-ventricle kwesokunxele ngenxa yezifo ze-myocardial. Izifo ezinjalo zivusa ukwakhiwa kwe-hemodynamic ngokweqile kwalesi sigaba senhliziyo.

Isizathu salolu hlobo lokuntuleka kungase sibe yi- vegetative dystonia futhi kunciphise ithoni ye-papillary musculature.

Kumele kuqashelwe ukuthi ukugula okusebenzayo akuyona isifo senhliziyo.

I-mitral valve enganele ngokwanele yemvelo ivela ngenxa yokulimala okwenziwe nge-anatomical emathethini ama-filaments ayo noma ngokuqondile.

Inkambo yesifo ingahle ibekwe njenge-acute noma engavamile.

Esikhathini sokuqala, ukungakwazi ukusebenza kungumphumela wokulimala kwendandatho yayo ngenxa yokwakheka kwe-abscess ngemuva kwesizinda sokuphefumula noma ukuhlukumezeka (ikakhulukazi ngesikhathi sokuhlinzwa). Ngaphezu kwalokho, imbangela yesifo esiyingozi ingaba ukwephulwa kobuqotho be-valve njengomphumela we-perforation noma ukubhujiswa, i-myxoma atrium.

Ukuthuthukiswa okufanayo kwalesi sifo nakho kuyisici sokungasebenzi noma ukulimala emasculature amaphepha.

Inkambo engapheli yalesi sifo ivela emlandweni wokuvutha (i-scleroderma, i-rheumatism, i- systemic lupus erythematosus) ne-degenerative (i-calcification fibrosus ring, i-Ehlers-Danlos ne-Marfan syndrome, i-pseudocanthoma) izinguquko. Ithonya linalo kanye nesifo sofuzo esiswini. Amacala anjalo afaka i-fibroelastosis ye-endocardium, ukuhanjiswa kwezitsha eziyinhloko, okungahambi kahle ekuthuthukiseni umthambo we-coronary wesokunxele. Ukwehluleka okungapheli kwenzeka uma ukukhubazeka kwe-fusion kwenzeka ngesikhathi kuhlanganiswa kwe-intrauterine ye-rudiments ye-valve. Ngenxa yalokho, imithwalo endocardial ayixhunyiwe. Ukuchithwa kweMikksomatous kwe-valve mitral (ama-valve awo) nakho kuvela ngendlela engapheli.

Yiqiniso, ukuphulwa komsebenzi wokuvala kungashukunyiswa nezinguquko zesakhiwo. Zibonakaliswa, njengokungumthetho, ekufweni kwe-cardiomyopathy, ukwehlukana kwe-tendon lobes (eyesibili ngenxa ye-infarction ye-myocardial, i-prolapse, i-traumas, kanye nokuzenzekela), i-paraprosthetic fistula evela ekuqhumeni kwe-sutures.

Ukwanele okungapheli kungabangela ukuphela kwe-infective endocarditis eyakhiwe ku-valve yomdabu noma isisu.

Ngokuya ngobukhulu bokuphindaphinda, kunezigaba ezintathu.

Iyokuqala - engazange ivezwe - ibonakala ngokumbula isicelo esiphezulu segazi kuphela ku-valve. Ezingeni lesibili kukhona ukwanda okulinganisiwe kwe-auricle. Isicelo esiphendukayo siyinto ejwayelekile engxenyeni yayo ephakathi.

Ngezinga lesithathu kukhona ukuhanjiswa okuphawulekayo. Kulesi simo, umthamo wokulawula ungafinyelela esifundeni esilandelayo sedonga ngakwesokunxele.
