Mitral valvụ insufficiency

Mitral valvụ insufficiency mere site a aghara na mmechi ọrụ. E nwere nsogbu n'ihi deformation na flaps bụ n'ozuzu fibrous agwa. Mmetụta na mmepe nke ọrịa nwere ọnya subvalvular akụkụ, nakwa dị ka ike n'ezi ihe nke ụfọdụ anaghị ekwe nke valvụ ọcha. Dịkwa mkpa bụ dilatation na anulus fibrosus. All nke n'elu edu imesị nloghachi ije nke ọbara si ekpe ventricle n'ime ekpe atrium systole, na-eme a gụnyere ya ná nkeji ọbara mgbasa na mmepe nke akpa ume ọbara mgbali.

Odida nke mitral valvụ dịpụrụ adịpụ agwa bụ nke a nnọọ obere onu. Ndị dị otú ahụ a na steeti a na-e kwuru na naanị mmadụ abụọ percent nke ihe nile ikpe. Dị ka a na-achị, ndị mebiri mmechi ọrụ na-esonyere stenosis nke mitral valvụ ma ọ bụ aortic obi ntụpọ.

The ọnọdụ nwere ike na-ọtọ ma ọ bụ organic okike.

Ke akpa idaha, ọdịda nke mitral valvụ amalite n'oge mgbasa na olu nke ekpe ventricle dị ka a n'ihi nke myocardial ọrịa. Ọrịa ndị dị akpasu guzobe hemodynamic bufee nke obi muscle ngalaba.

The akpata ụdị ọdịda nwere ike autonomic dystonia na papillary Akwara ụda Mbelata.

Ọ ga-kwuru na ọtọ aghara metụtara obi ọrịa.

Enweghị organic ọdịdị nke mitral valvụ emee ka a n'ihi nke anatomical lesion ma ọ bụ akwara ya eri ozugbo onwe ya.

The ọrịa nwere ike nkewa dị ka nnukwu ma ọ bụ ala ala.

Ke akpa idaha odida bụ a n'ihi mmebi ya mgbanaka site guzobe ihe etuto na ndabere nke infective endocarditis ma ọ bụ mmerụ (tumadi n'oge ịwa ahụ). Ọzọkwa, ihe na-akpata nnukwu ọrịa nwere ike ịghọ eruba flaps ike n'ezi mebiri dị ka a n'ihi nke perforation ma ọ bụ mbibi, atrial myxoma.

Ndị dị otú ahụ a na mmepe nke ọrịa na e ji dysfunction nke ma ọ bụ mmebi nke papillary uru.

Adịghị ala ala ọrịa na-ebilite megide mkpali (scleroderma, rheumatic fever, systemic lupus erythematosus) na degenerative (calcification nke annulus fibrosus, Ehlers-Danlos ọrịa na Marfan si, pseudoxanthoma) mgbanwe. Mmetụta ebum pụta ụwa na Jenesis. N'ihi na otú ahụ ikpe ga-zoro fibroelastosis endocarditis, transposition nke oké arịa, na anomaly na mmepe nke ekpe akwara akwara. Adịghị ala ala ọdịda pụtara na ịda iwu mmakọ n'oge nwa ebu n'afọ na primordia guzobere valvụ. N'ihi ya, ọ dịghị compound endocardial cushions. Myxomatous mbelata nke mitral valvụ (ya flaps) na-na-emepe emepe na-adịghị ala ala ụdị.

N'ezie, ndị mebiri nke mmechi ọrụ nwere ike triggered na bughi mgbanwe. Ha na-egosipụta, na-emekarị na hypertrophic cardiomyopathy, ezumike chords akwara (n'ihi na nke abụọ myocardial infarction, prolapse, mkpasasị uche, nakwa dị ka n'amaghi) paraproteznoy fistula ịda ruru mgbawa nke isi agịga Ma do.

Adịghị ala ala ọdịda nwere ike ịrụpụta infective endocarditis, guzobere nwa afọ ma ọ prosthetic valvụ.

Dabere na ogo regurgitation bụ atọ degrees.

First - unexpressed - e ji nchọpụta nke ọbara nloghachi arịrịọ naanị na valvụ. Mgbe nke abụọ ike hụrụ agafeghị oke mgbasa atrium. N'ihi ya postback e ji mara nke ya n'etiti akụkụ.

Na-atọ ogo e bukwanu dilatation. N'ihi ya reguritatsii ugbu a nwere ike iru n'azụ obodo nke mgbidi na ekpe atrium.
