Kaafi waalka Mitral

kaafi waalka Mitral sababa jirro in shaqo xiritaanka. Waxaa jira khalkhal ay sabab u tahay calaamadaha lahayo ee qaybood waa dabeecad guud ahaan buunshada ku. Saameynta horumarinta cudurka leeyihiin lesions dhismeedka subvalvular, iyo sidoo kale daacadnimada cudurada qaar ka mid ah xubno ka waalka. Waxaa sidoo kale muhim waa Dilatation ee fibrosus anulus. Dhammaan oo ka mid ah raad kor ugu danbeyn dhaqdhaqaaqa soo laabashada dhiigga ka ventricle bidix galay systole ee bidix, sababaya hoos u dhac ku wareegga dhiigga daqiiqo iyo horumarinta hypertension pulmonary.

Ka gaabinta ee waalka mitral go'doonsan qof iska arrin aad u dhif ah. gobolka noocan oo kale ah waxaa lagu xusay in boqolkiiba kiisaska oo dhan kaliya labo. Sida caadiga ah, shaqo xiritaanka xadgudubka waxaa ku weheliyay stenosis ah mitral biiyaha ama cilladaha wadnaha aortic.

xaalada waxay noqon kartaa nooca functional ama organic.

Xaaladda hore, failure oo ka mid ah mitral waalka yeesho inta lagu guda jiro ballaarinta in mugga of ventricle bidix oo sabab u ah cudurro myocardial. cudurada noocan oo kale ah ka cadhaysiinina formation of dollar hemodynamic waaxda muruqa wadnaha.

Sababta oo ah noocan ah failure waxaa laga yaabaa in dystonia autonomic iyo papillary hoos cabirida xaalada muruqa.

Waa in la ogaadaa in cudurka functional ma la xiriira cudurada wadnaha.

La'aanta dabiiciga ah organic ee waalka mitral dhacaa sabab u ah nabar jidh ama si toos ah seedaha threads ay qudhiisa.

Cudurku loo kala saari karaa sida daran ama joogtada.

Xaaladda hore failure waa natiijo ah oo waxyeelo ay giraanta by formation of malax ah ku saabsan asalka ah endocarditis infective ama dhaawac (inta lagu guda jiro qalliinka). Waxaa intaa dheer, sababta oo ah cudur ba'an laga yaabaa inay noqdaan qaybood socodka xadgudub daacadnimada iyadoo ay sabab u daloolin ama burburinta, myxoma wadne.

horumarinta noocan oo kale ah ee cudurka iyo waxa lagu gartaa cillad ah ama dhaawac murqaha papillary.

cudurada Chronic baxdo ka dhanka ah bararka (scleroderma, qandho rheumatic, lupus erythematosus oo nidaamsan) iyo side (kalshum fibrosus annulus ah, Ehlers-Danlos Syndrome iyo Marfan ee, pseudoxanthoma) isbedel. Influence dhalin iyo Bilowgii. Waayo, kiisaska noocaas ah waa in loo gudbiyaa endocarditis fibroelastosis, transposition of weelashii weyn, logu talagalay ee horumarinta halbowlaha wadnaha ee bidix. failure Chronic dhacdaa midowga xadgudub lagu jiro uurjiifka waalka formation primordia. Sidaas awgeed, ma jiraan wax Barkimo endocardial xarunta. xumaanshaha Myxomatous ee waalka mitral (qaybood ay) waxaa sidoo kale horumarinta qaab raaga.

Dabcan, xadgudub ee function xiritaanka laga yaabaa in lagu kiciyay iyo isbedelka dhismaha. Waxay muujiyaan, sida caadiga ah ee cardiomyopathy hypertrophic, nasasho chords seedaha (taasoo keentay in Wadnaxanuun sare myocardial, prolapse, kuwa dhimirka, iyo sidoo kale lama filaan ah) fistula paraproteznoy timi sabab u tahay qarax of tolay.

failure Chronic ku keeni karta endocarditis infective, aasaasay in waalka hooyo ama bedalay.

Iyadoo ku xiran darnaanta regurgitation jira saddex darajo.

First - sheegin - waxa lagu gartaa ogaanshaha codsiga dhiig soo laabtay oo kaliya at waalka. Marka awood labaad arkay Atrium ballaarinta dhexdhexaad ah. dabeecad Sayidka postback ay qayb dhexe.

In heerka saddexaad waxaa jira Dilatation badan. Sayidka hadda reguritatsii gaari karaan gobolka danbe ee derbiga ah ee bidix ka.
