Isiphako se-mitral valve ngenye yezona ziphosakeleyo zentliziyo. Zonke iintsilelo zentliziyo zichaphazela umgangatho wentliziyo. Zingabini zomntwana, kwaye zifunyenwe ngenxa yezifo ezidlulisiweyo.
I-mitral valve ibizwa ngokuba yinkqubo enzima kakhulu, eyenziwe ngamacwecwe amabini amancinci, abuye alawulwe iindidi ezahlukeneyo zamathambo kunye namagatya. Umsebenzi olungelelanisiweyo wezo zonke iinkcukacha zengqondo zinoxanduva lokuvala nokuvula isiqalo se-mitra ngexesha lokwahlukana kwentliziyo yesisu.
I-malformation ye congenital ye-mitral valve
Ukuba isiphene saloo valve sikhona ukusuka ekuzalweni, njengomthetho, iziphene ezihamba kunye nazo ziyaqhotyoshelwa kuyo, ukuya kutshintshulwa kwinqanaba elingaphandle lentliziyo. Kodwa kwakukho neengcinga ezinjalo ekuphuhliseni okuqhelekileyo kwe-ventricle ekhohlo, umzekelo, ukungakwazi ukusebenza kwe-valve mitral.
Iintsilelo zentsapho ekuphuhliseni i-valve, eziza kufuna unyango olukhawuleza lwezilwanyana zonyango, zincabile kakhulu. Isiphene esiqhelekileyo sisifo se-mitral valve.
Iimpawu zesiphene eso asizibonakali ngokwayo nayiphi na indlela. Ngokuqhelekileyo ukuxilongwa okunjalo kufumaneka kumntwana ofunyaniswa ukuba unomsindo osebenzayo. Kwaye sele sele iqhutywe i-echocardiography, imbangela yezi bhulozo zicaca.
Isiphene se-mitral valve ayifuni unyango lotyando ukuba aluyi kubangela ukungaphumeleli kwentliziyo.
Iimpazamo ze-mitral valve
Iyona ntsilelo yesimo senhliziyo i-rraumatic defect. Iyenzeka ngenxa yezifo ezithathelwanayo ezidluliselwayo, umzekelo, i- angina . Kwiimeko ezinjalo, izidakamizwa ezichasayo nezichasayo zichazwe. Into ebaluleke kakhulu kukufumanisa isibetho ngexesha kunye nokunika unyango olungileyo. Kwimiba enzima kwaye inganakukhatyathwa, khetha imisebenzi.
