Mitral insufficiency thiab nws cov kev kho mob

Mitral insufficiency - ib tug pathological kev npaj feem ntau thaum lub sij hawm nram qab no cov kab mob: rheumatism, mob endokardit.Znachitelno tsawg nws muaj raws li ib tug tshwm sim ntawm calcification ntawm lub mitral nplhaib, lub plawv valve txhab nyob rau hauv mauj scleroderma los yog mauj lupus erythematosus, raws li zoo raws li aortoarteritis, kab mob ntawm lub connective cov ntaub so ntswg - syndromes Eilers-Danlos thiab Marfan. Raws li teeb meem kev zais pa valvuloplasty yog tseem tau lub rov tshwm sim ntawm tus kab mob no.

Mitral insufficiency muaj vim kev sib tawg ntawm lub chord los yog papillary nqaij, xws li myocardial infarction. Lub sij hawm ntawm ua kab mob endocarditis tau sai puas tsuaj los yog kev puas tsuaj rau Valve leaflets. Nyob rau hauv nqa tawm lub valve prosthesis yuav tsim teeb meem - okoloklapannaya regurgitation.

Tus kwv tij mitral insufficiency yuav tsim vim lub expansion lag hauv lub plawv (thaum myocardiodystrophy, myocarditis, cardiomyopathy, ischemic plawv tus kab mob).

Nws muaj ob hom ntawm mitral insufficiency: mob thiab ntev.

Cov yam ntxwv cov tsos mob ntawm tus kab mob mob yog ces sab laug ventricular tsis ua hauj lwm nrog cov accession ntawm hypotension thiab pulmonary edema. Feem ntau muaj yog atrial fibrillation, tsawg yuav muaj atrial yeej.

Mob mitral regurgitation yog ib tug ntev lub sij hawm (txog 10 xyoo) tshwm sim muab zais. Ces, muaj cov twb tsis txaus siab cov yam ntxwv ntawm lub plawv tsis ua hauj lwm: ua tsis taus pa rau rau siab, qaug zog. Tej zaum cov tsos ntawm cov tsos mob Ortner: zoo nkaus li txhaws qa vim compression ntawm enlarged lub plawv recurrent paj. Tom qab tuaj koom los ntawm hnoos thiab hemoptysis, o vim lub pronounced stagnation nyob rau hauv me me thiab cov loj loj ncig.

Thaum saib ntawm xws li ib tug neeg mob tej zaum yuav tau txais ob daim di ncauj cyanosis. Qhov no mitral lub plawv kab mob no yog yus muaj los ntawm tus mem tes ntawm qhov nruab nrab cov ntsiab lus. Tej zaum tachypnea. Lub xaav cov apical impulse tshwm sim mus rau sab laug, nws yuav diffuse thiab ntxiv dag zog rau; muaj teeb meem loj mitral regurgitation tshwm sim systolic jitter nyob rau hauv lub apex ntawm lub plawv.

Auscultation mitral insufficiency tsiag ntawv los ntawm cov tsos systolic yws yws ua nyob rau apex, uas yog zoo ua nyob rau hauv lub axillary cheeb tsam. Nws kuj yus muaj los ntawm ib tug weakening nyob rau hauv lub apex ntawm lub plawv kuv laus.

Mitral lub plawv tsis xws luag, uas muaj xws li mitral regurgitation yuav tsum tau yuav tsum tau kev kho mob, kev cais tawm - mob asymptomatic. Thawj tsa diuretics (furosemide) thiab peripheral vasodilators (sodium nitroprusside). Kom muaj lub hemodynamics ntawm qub ntau ntau, yuav siv intra-aortic zais pa counterpulsation.

Phais kho mob yog nqa tawm kev noj mus rau hauv tus account lub zwj ceeb ntawm cov neeg mob thiab ua kom muaj mitral insufficiency. Piv txwv li, nyob rau hauv ua kab mob endocarditis mob mitral valve insufficiency nyob rau hauv lub tom ntej no hnub yuav tsum tau kev phais, thiab myocardial infarction feem kev siv ntawm ib tug conservative kev kho mob.

Txawm li cas los ntawm lub etiology ntawm vice tsim nyog los nqa tawm tiv thaiv ntawm ua kab mob endocarditis.

Pib ntawm cov tsos mob yog ib tug hais rau phais kho mob. Lag luam kev xaiv - yas mitral valve. Qhov no pub rau ib tug zoo synchrony nyob rau hauv rau sab laug ventricular contraction thiab tsis yuav tsum tau tas mus li anticoagulation. Nyob rau hauv lub xub ntiag ntawm calcifications thov mitral valve. Annuloplasty yog siv nyob rau hauv cov kev kho mob ntawm txheeb ze mitral insufficiency.
