Lwemiphunga yentliziyo nokufakelwa: iimpawu ngokobugcisa kwesango

Izixhobo vana kwentliziyo ezisebenza umsebenzi ebalulekileyo ekuqinisekiseni ejikeleza efanelekileyo kwegazi. Nganye valve yenhliziyo (abangama-ezine), lokuvula synchronously nokuvala, kuthintela ukuhamba kwegazi ukugeleza kwicala umva. Oko inika ukuvumelana egqibeleleyo usenokungachani eliphezulu yonke indlela welungu engundoqo omzimba womntu.

Ukuba sithelekisa egumbini kwentliziyo kunye kwesango, ivelufa intliziyo idlala indima kwamaphiko akhe. Ngamnye kubo uneempawu zawo kunye nenjongo. Aortic yentliziyo nokufakelwa osetyenziswa ukuvala umnyango ukuya aorta. Anatomically, kuba iqulathe amaphiko ezintathu ezifana kwezaa ntsimbi. Xa ventricle lasekhohlo intliziyo, ngalo mbhojana ukwehla ivumela igazi flow kungena aorta.

umphini Mitral ukuba isakhiwo unefoni, ephakathi ventricle yasekhohlo kunye intendelezo, umnyango apho uyawavala, ngaloo ndlela ethintela kwicala reverse yokumpompoza kwegazi. Flasher lakhe uhambisana ngokupheleleyo kunye ventricle ngasekhohlo.

valve Tricuspid wentliziyo, ebizwa kwakhona nge tricuspid ephakathi ventricle kunye intendelezo kunye ngasekunene, njengoko kubonakala ukusuka igama layo, iye isakhiwo ezintathu. Kule meko evulekileyo, igqitha igazi ukusuka intendelezo ekunene ukuya lweHo- ventricle, ukugcwaliswa ngokupheleleyo ebangela izihlunu ucutheko reaction, apho kwenzeka kukuvalwa vana. Yeyiphi ethintela ukuhamba umva kwegazi nokuqinisekisa kwegazi yayo kwicala elifanelekileyo.

ivalve pulmonary, sise kwisamkeli igalelo kulo mzimba, iqinisekisa intshukumo igazi ukusuka ventricle ekunene ukuya imithambo miphungeni. Olu isakhiwo jikelele kunye injongo yomsebenzi izixhobo valvular intliziyo. Ngoko kucacile ukuba ukusebenza kakuhle kwenkqubo yokujikeleza iphela umzimba engundlunkulu kuphela kunokwenzeka kunye nokusebenza kakuhle nokugqibelela indlela eziphilayo.

A phawu uphawu kwemithambo kukuba baphantsi umsebenzi rhoqo ngomatshini ziphantsi layisha phezulu. Kuqikelelwa ukuba bangaphezu asixhenxe iminyaka umjikelo wobomi kwemithambo yokufumanisa - ukuvalwa amaxesha ngaphezulu kwezigidi ezibini. Oku kudla ngokukhokelela ezimbi ezahlukeneyo. Zalo (enezinto) kwezivalo esempilweni ilaphu angamarhoqorhoqo, irubhrikhi kakhulu imilo lwezibalo egqibeleleyo. Ngokuqhelekileyo, lilaphu loo ubethwa ukunxiba. Ukongeza, isifo badla ezinokubangelwa kwasekuzalweni. Kwemithambo ukuze ezonakeleyo boyikiswa ngenxa alekwe ukuhlaselwa samathambo, zizifo ezahlukahlukeneyo, izizathu yemfuza, ngenxa yeenguqu ezinxulumene-ubudala, isifo sentliziyo , kunye nobuninzi nezinye izinto.

Konke oku kunokubangela stenosis (licuthe ugwebu) okanye ukusilela (i ukuvalwa engaphelelanga le enezinto). Ngamanye amaxesha kwiimeko ezinjalo angafuna utyando entliziyweni vana ekufuneka nokubuyiselwa okanye indawo. Nangona ubuchwepheshe bale mihla kunye nezinto kwenza kube lula ukwenza loo inkqubo onzima nobilis kunye namathuba eliphezulu kakhulu impumelelo, le ngozi ebese phezulu kakhulu.

Eyona ixhaphakileyo namhlanje kwenziwa utyando ukuvuselelwa "krobo" yentliziyo nokufakelwa - le mitral. Ukuba umonakalo omkhulu inkqubo vana replacement ntonje usindiso kuphela isigulane. Surgery, ziingozi yawo yonke, mkhulu kude ngokwemigaqo ukusebenza naluphi na unyango.
