Mitral vavu insufficiency

Mitral vavu insufficiency chifukwa cha matenda mu kutsekera ntchito. Pali chisokonezo chifukwa mapindikidwe mu kutseka kuti uchiwo usatuluke zambiri fibrous khalidwe. Impact pa chitukuko cha matenda ndi zotupa nyumba subvalvular, komanso kukhulupirika kwa matenda ena a zinthu valavu. Mofanana kwambiri ndi dilatation mu fibrosus anulus. Onse atsogolera pamwamba kenako kubweranso kayendedwe ka magazi kuchokera ventricle kumanzere mu anasiya atrium systole, kuchititsa kuchepetsa mphindi magazi ndi chitukuko cha matenda oopsa m'mapapo mwanga.

Kulephera kwa mitral vavu olekanitsidwa khalidwe limabweretsa chodabwitsa chosowa kwambiri. okhumudwa limatchula peresenti awiri okha milandu onse. Monga ulamuliro, kuphwanya kutseka ntchito limodzi ndi stenosis wa mitral vavu kapena kupunduka kung'ambika mtima.

chikhalidwe akhoza kukhala zinchito kapena organic chikhalidwe.

Mbali yoyamba, kulephera kwa mitral vavu akufotokozera pa Kukula buku la ventricle kumanzere chifukwa cha matenda m'mnyewa wamtima. matenda imautsa mapangidwe hemodynamic zimamuchulukira wa dipatimenti mtima minofu.

Chifukwa cha mtundu kulephera kungakhale autonomic dystonia ndi papillary kuchepetsa minofu kamvekedwe.

Tikumbukenso kuti matenda zinchito zosagwirizana ndi matenda mtima.

Kupanda chikhalidwe organic wa valavu mitral kumachitika chifukwa cha chotupa anatomical kapena tendons ulusi wake mwachindunji yekha.

Matendawa akhoza wachinsinsi monga yopweteka kwambiri kapena yokhalitsa.

Mbali yoyamba kulephera ndi zotsatira za kuwonongeka kwa mphete yake mwa mapangidwe abscess pa maziko a endocarditis infective kapena kuvulala (makamaka opaleshoni). Komanso, chifukwa cha matenda pachimake akhale otaya kutseka kuti uchiwo usatuluke kukhulupirika kuphwanya chifukwa cha perforation kapena chiwonongeko, matenda myxoma.

Chotero chitukuko cha matenda ndi amakhala ndi kukanika kapena kuwonongeka kwa minofu papillary.

matenda aakulu ukapezeka ndi yotupa (matendawa, enaake ophwanya m'thupi, zokhudza zonse lupus erythematosus) ndi osachiritsika (calcification wa annulus fibrosus, Ehlers-Danlos Syndrome ndi Marfan a, pseudoxanthoma) kusintha. Mphamvu titadziwa ndi zidakwa. Pakuti Zikatero ayenera kunena fibroelastosis endocarditis, transposition ziwiya chachikulu, anomaly mu chitukuko cha mtsempha wamagazi kumanzere inatsekeratu. Matenda kulephera limapezeka pa siudzalandilidwa ngathi lamulo pophatikizana pa yoopsa vavu mbalizo mapangidwe. Choncho, palibe cushions pawiri endocardial. Myxomatous alibe wa valavu mitral (kutseka kuti uchiwo usatuluke ake) amadziwikanso osauka mawonekedwe aakulu.

Inde, kuphwanya kutseka ntchito amayamba ndi kusintha structural. Akamauzana, kawirikawiri mu cardiomyopathy hypertrophic, yopuma makodi tendons (chifukwa mu sekondale m'mnyewa wamtima infarction, prolapse, mabvuto, komanso lachibadwa) paraproteznoy fistula akuwuka chifukwa kuphulika kwa sutures.

Matenda kulephera chingachitike n'chiyani endocarditis infective, aumbike mwa valavu nzika kapena apulasitiki.

Malinga ndi kukula kwa regurgitation madigiri atatu.

Choyamba - asanawonetseredwebe - amakhala ndi kudziwika pempho magazi kubwerera okha pa vavu. Pamene mphamvu wachiwiri anati zolimbitsa kuwonjezeka atrium. Choncho postback khalidwe la mbali pakati.

Mu digiri wachitatu pali umboni dilatation. Choncho reguritatsii panopa angafikire kumbuyo m'chigawo cha khoma mu atrium kumanzere.
