Isici se-mitral valve singenye yeziphambeko zenhliziyo ezivame kakhulu. Zonke iziphambeko zenhliziyo zithinta ikhwalithi yenhliziyo. Kungaba kokubili kokuzalwa, futhi kutholakale ngenxa yezifo ezithintekayo.
I-valve ye-mitral ibizwa ngokuthi iyinkimbinkimbi kunazo zonke, ezakhiwe ngamacwecwe amabili amancane, aphinde alawulwe izinhlobonhlobo zemisipha yamapill kanye nama-valve. Umsebenzi odidiyelwe wezo zonke lezi zindaba zenhliziyo unesibopho sokuvala nokuvula i-mitral orifice ngenkathi kukhishwa kwemisipha yenhliziyo.
I-malformation ye-congenital ye-valve mitral
Uma iphutha le-valve elinjalo likhona kusukela ekuzalweni, njengombuso, izintambo ezihlukahlukene ezihambisana nazo zihlanganisiwe kuwo, kuze kube yilapho kungaphili kahle kwengxenye yonke yesokunxele yenhliziyo. Kodwa kwakukhona nemikhuba enjalo ekuthuthukiseni okujwayelekile kwe-ventricle kwesokunxele, isibonelo, ukungakwazi ukusebenza kwe-valve mitral.
Ukukhubazeka okubangelwa yi-congenital ekuthuthukiseni i-valve, okuzodinga ukwelashwa okusheshayo kwabahlinzayo benhliziyo, kuyinto engavamile kakhulu. Iphutha elivame kakhulu yi-mitral valve prolapse.
Izimpawu zesiphambeko esinjalo azikhombisi ngokwabo nganoma iyiphi indlela. Ngokujwayelekile ukuxilongwa okunjalo kungatholakaliswa kwengane etholakala ukuthi inomsindo osebenzayo. Futhi kakade ngenkathi kwenziwa i-echocardiography, imbangela yalezi zomsindo iyacaca.
Iphutha le-valve ye-mitral ayidingi ukwelashwa kokuhlinzwa uma kungabangeli ukuhluleka kwenhliziyo.
Amaphutha we-mitral valve atholakele
Isifo senhliziyo esivamile kakhulu se-mitral valve sinesifo se-rheumatic. Kuvela njengesifo sezifo ezithathelwanayo ezithathelwanayo, isibonelo, angina . Ezimweni ezinjalo, izidakamizwa ezilwa nezifo ezithathelwanayo nezilwa ne-antirheumatic zinqunywe. Into ebaluleke kakhulu ukuthola lesi sifo ngesikhathi bese ubeka ukwelashwa okufanele. Ezimweni ezinzima kakhulu nokunganakwa, khetha imisebenzi.
