Mitral valve insufficiency

Mitral insufficiency umphini ebangelwa akaphilanga, umsebenzi wokuvala. Kukho ukuphazamiseka ngenxa deformation kwi beziya kuba ubhalo ezinezikhondo ngokubanzi. Iimpembelelo kuphuhliso izifo amanxeba izakhiwo subvalvular, kwakunye ingqibelelo ukuphazamiseka ezithile izinto vana. Enye into ebalulekileyo dilatation kwi fibrosus anulus. Zonke umkhondo ngentla ekugqibeleni yintshukumo ukubuya igazi ukusuka ventricle ekhohlo ukuya intendelezo systole ngasekhohlo, ebangela ukuncitshiswa ejikeleza ngaphandle kwegazi ngcaciso imfutshane kunye nophuhliso wegazi miphungeni.

Ukungaphumeleli ka vana mitral bodwa umlinganiswa bobabo into enqabileyo kakhulu. Loo urhulumente uphawuleka ekhulwini ezimbini kuphela zonke iimeko. Ngokuqhelekileyo, umsebenzi ukungathobeli lokuvala sikhatshwa stenosis le mitral vana okanye iziphene intliziyo aortic.

Imeko ibe uhlobo esebenza okanye organic.

Kwimeko yokuqala, ukusilela ye mitral vana kuqala nokwandiswa umthamo ventricle lasekhohlo ngenxa yezifo engabalulekanga. izifo ezifana bawaphikise ukuyilwa ukucima kombane hemodynamic yesebe kwentliziyo kwezihlunu.

Unobangela wale hlobo ukusilela inokuba DYSTONIA yawo kunye nokunciphisa kwezihlunu papillary.

Kufuneka kuqatshelwe ukuba sigulo esebenza na ezinxulumene izifo intliziyo.

Ukunqongophala uhlobo somgquba vana mitral kwenzeka ngenxa sisilonda esidumbileyoesingaphakathi yokwakheka okanye nemisipha imisonto yayo ngqo ngokwakhe.

Isifo kuchazwa oyingozi okanye engapheliyo.

Kwimeko yokuqala ukuhluleka ngenxa yomonakalo ukuba ikhalele kwayo ukuyilwa ithumba imvelaphi endocarditis infective okanye ukwenzakala (ubukhulu becala ngexesha utyando). Ngaphezu koko, unobangela yesifo etsolo abe flow beziya ingqibelelo ukungathobeli ngenxa ye perforation okanye ukutshatyalaliswa, myxoma atrial.

Loo uphuhliso isifo kwaye luphawulwa kwekhono okanye umonakalo kwizihlunu papillary.

kuvela izifo ezondeleyo nxamnye ukudumba (scleroderma, samathambo, systemic lupus zomzimba) kunye sisiba mandundu (calcification le fibrosus annulus, Ehlers-Danlos Syndrome kunye yiMarfan kaThixo, pseudoxanthoma) utshintsho. Impembelelo isegazini kunye nesisekelo. Kuba Kwiimeko ezinjalo kufuneka ibhekiswe fibroelastosis endocarditis, transposition yeempahla enkulu, anomaly kwi kuphuhliso kwemithambo ekhohlo. ukusilela Chronic kwenzeka xa ulwaphulo nokudibana ngexesha foetal primordia Ukwakheka vana. Ngenxa yoko, akukho mfuma compound endocardial. yamehlo Myxomatous ka vana mitral (enezinto zayo) nalo asakhulayo ngendlela ezigulo ezondeleyo.

Kakade ke, lo nokuhluthwa umsebenzi wokuvala kuxhokonxwa kunye utshintsho lobume. Babonakalisa, ngokuqhelekileyo cardiomyopathy hypertrophic, ikhefu ukulele imisipha (kukhokelela iqhosha eziziisekondari engabalulekanga, prolapse, unxinzelelo, kwakunye kulogo) paraproteznoy fistula ezivele ngenxa mlilo sutures.

ukusilela ezondeleyo enokubangelwa endocarditis infective, kwasekwa ivelufa lomthonyama okanye angoozenzele.

Kuxhomekeka ubuzaza regurgitation ezi degrees ezintathu.

Okokuqala - engavezwanga - luphawulwa ekufumanekeni yesicelo ukubuya igazi kuphela vana. Xa amandla yesibini lathi ngcathu ukwanda intendelezo. uphawu Ngaloo postback zenxalenye yayo ephakathi.

Kwinqanaba wesithathu kukho dilatation omkhulu. Ngoko ke ngoku reguritatsii unako ukufikelela kummandla ngasemva udonga intendelezo ekhohlo.
