Isifo sentliziyo Acquired: stenosis mitral

Ukuvala liso phakathi ekhohlo ezingontsini zentliziyo , eyaziwa ngokuba stenosis mitral njalo organic. Isizathu esiyintloko uphuhliso nesifo sentliziyo ezifunyenwe - endocarditis rheumatism. ngaphantsi kakhulu kunjalo stenosis mitral endocarditis ezinye imvelaphi.

Ukuvala orifice atrioventricular liphuhlisa ngenxa ngxubevange na amaphetshana ka vana mitral kunye namanye, ukuqina lwabo uphawu. Ivelufa kuthatha ngokohlobo kovalo kunye noqhoqhoqho zibekwa umngxuma phakathi okanye imilo ifanele.

Le ndawo orifice mitral ngokuqhelekileyo 4 - 6 macala onke. cm. Mitral stenosis kukhokelela utshintsho egazini flow entliziyweni. ukuphazamiseka Hemodynamic kuvela xa ukuvala somnyango 1.5 macala onke. cm. Ngexesha diastole, igazi intendelezo ekhohlo akazange abe ixesha ukuya ngokupheleleyo ventricle ekhohlo. Ngoko, kwi intendelezo lasekhohlo kuku imali encinci yegazi, apho idityaniswe igazi evela yegazi miphungeni. Ngenxa yoko, intendelezo leyo ugalelwe igazi kwandisa uxinzelelo kuyo, nto leyo kuqala ukubuyekeza izishunqulelo inzuzo kunye twa atrial. Kodwa njengoko udonga dystrophy ye intendelezo obuthathaka, ukuba kungekudala zancitshiswa contractility, ukuxinana ukwanda kunye noxinzelelo kwaphinde lekhamera. Ekuhambeni kwexesha kukho ngxi igazi kuye kwasasazwa pulmonary, ukwandisa umthwalo ventricle ekunene, kukho nokumfixana olujikeleza wesangqa enkulu.

Nge stenosis mnene izikhalazo isiguli ukuba umsebenzi emzimbeni akukho kakhulu imiqathango. Isikhalazo yokuqala, ibonisa imbonakalo ekuma kwi izitya kwegazi pulmonary nje, iphika ukhohlokhohlo - ezomileyo okanye imali encinci isikhohlela, kwakunye lidiniwe kunye iyangongoza. Kwixesha elizayo, kukho hemoptysis kunye nokuhlasela nezolo yesifuba intliziyo. Intlungu entliziyweni uvela nama-10% yezigulane.

Pulse kusenokungabikho into enye kuzo zombini iingalo. Oku kungenxa yokuba intendelezo eyandisiweyo ekhohlo licudisa ekhohlo subclavian kwemithambo, wazalisa intliziyo nokuncipha ekhohlo. Amaxesha amaninzi kukho fibrillation atrial.

Ngokucofa-njengezona intliziyo emiselwe umqondiso purr bekati ngayo. purring ngwe ivela xa igazi udlula le orifice mitral kuguquka.

imida emgama intliziyo sagqitywa lisisiqalo wobomi kwaye ngasekunene, leyo kwenzeka ngenxa utshintsho emagumbini ngamnye zentliziyo, ufumana uqwalaselo mitral.

Auscultation entliziyweni kubaluleke kakhulu lokufunyaniswa vice njengoko stenosis mitral iye lwengoma eqhelekileyo auscultatory. Ngaphezu enkcochoyini kwentliziyo auscultated sonorous ngokuqhwaba isandi sokuqala, nisikrokrele ukuzala kunye neetoni ezongezelelweyo eziveliswe ngethuba kuvulwa ivalve mitral. Konke oku kwenza uncuthu eqhelekileyo auscultatory, ekuthiwa izagwityi isingqisho. Ngomhla esisekweni intliziyo ngendlela auscultated noqhekeko okanye ithoni cleavage II, ukubonakala leyo enxulumene kokoma igazi emiphungeni.

uxinzelelo lwegazi ngokuqhelekileyo akawatshintshi loo manqaku, maxa wambi kuyehla iSystolic kunye ukuzala ukunyuka.

ekuxilongweni

Ngomhla radiograph ixhomekeke khona uqwalaselo basis of intliziyo, ebizwa ngokuba mitral kunye ingxinano.

Le ECG - Iimpawu ze wawandisa nasemagumbini intliziyo.

Ezi PCG phinda iziphumo auscultation kwentliziyo.

Kubaluleke kakhulu kwi lokufunyaniswa iziphene echocardiography zisuswe, sivumele ivelufa ukumisela deformation, ukuqina kunye calcification enezinto zayo, ukutshintsha umthamo kwamagumbi ngentliziyo, igazi udonga ubukhulu.

unyango

Unyango stenosis nawuphi lizwe kufuna uqhaqho. ukusebenza Stenoses vana sikuko ekwenzeni commissurotomy - asike amaphetshana valve iguqulwe kancinane. Le mitral kunye stenosis aortic, unyango leyo yenzelwa intsumpa, phambi kokuba umsebenzi ukuba zitshintshwe zibe linyathelo babuyekezwe.
