Nziyo dziri mumoyo wemwana - zvikonzero

Kushanda kunoshanda mukati memwoyo wecheche kunofungidzirwa sechimiro chekuratidzwa kwebasa romwoyo mukati mevana vane utano hwakanaka, asi zvinogonawo kuonekwa apo myocardium (musikana wemwoyo) yakaputsika, hemodynamics ishanduka. Uyezve, chimwe chezvikonzero zvakawanda zvekuonekwa kwemashoko akadai mumoyo wemwana angave, semuenzaniso, chirwere chekushaya ropa. Ruzha rwemhando iyoyo runowanzoti "asina mhosva", nokuti Kuvapo kwavo zvinenge zvisingabatsiri hutano uye huwandu hwemwana. Ngatiedzei kuona kuti "ruzha rwemwoyo" rwomwana runorevei, zvisinei kuti manzwi ose ane ngozi uye nei achioneka.

Ndezvipi zvinokonzera kukwidziridzwa kwechirusi mumoyo wemwana?

Tichifunga nezvezvinhu zvinotarisana nemoyo wehutano hwevana, zvinowanzosiyanisa zvinotevera zvikonzero zvekuonekwa kwechirwere chakadai:

• Valvular - tsvina yemagetsi emwoyo valves, asymmetry yemashivhiri yemagetsi, mamwe mavhavha emagunirari, trigonoidization yemagetsi emashizha emashizha;
• chordal - inozivikanwa nechitarisiko (chenhema) zvinyorwa zvevhirikiri ye mwoyo, kuchinja munzvimbo yavo, kuputsa kwekuchinja kwavo;
• papillary - kuchinja munzvimbo, chimiro, nhamba yemisumbu yemapillary, kushungurudzika kwemazwi avo nekupikisa nekuzorodzwa kwemutsipa wemwoyo;
• barrier-parietal - window yevhavharo yakasununguka (LLC), aneurysm ye septat interatriria, valve Eustachian, kushandiswa kwechimiro chechimiro chepamusoro chesevhenekeri inopindirana, nezvimwewo.

Zvose zvinoratidzirwa zvirwere mumishonga zvinonzi zviduku zvisinganzwisisiki zvekuvandudza moyo (MARS). Vanowanzobatanidzwa nehutano hwemwoyo hunokanganisa uye mumwe nomumwe, iyo inofanirwa kuongororwa painoongorora mamiriro emwana uye nekugadzirisa maitiro ekuzvibata kwake. Izvo zvipingamupinyi izvi zvinotungamirira kune kuonekwa kwechirwere chechiropa mumoyo wemwana muduku.

Mitral valve inowedzera sechikonzero chinowanzovhiringidza nenyuchi dze systolic

Sezvo wataura nezvekuti nei mwana ane ruzha mumoyo, uye zvaanoreva, funga chikonzero chinowanzoitika chechitarisiko chavo, icho chinonzi kupera kwe mitral valve.

Pakati pezvataurwa pamusoro apa vhuvular, zvinowanzoitika ndezve mitral valve prolapse (PMC). Ichi chirwere chinoratidzirwa sekudzivirira kwe 1 kana kuti magetsi ose aya evhavha, nenzira yekamuri yepamusoro iri pedyo nepakati. Maererano ne medstatistics, chirwere ichi chinoitika munenge 6 kusvika 6% yevana vemakore ose, kusanganisira vana vanozvarwa. Panguva imwe chete, vasikana vanotambura nechirwere ichi 2-3 kazhinji kakawanda.

Sezvo mutemo, kukurudzirwa kwekutanga kwePPP kunokonzerwa nekuderera kwezvibvumirano zvezvivako zvevhavha pachako, kuvapo kwezvinyorwa zvisingaoneki mumagetsi emagetsi.

Chimwe chechipiri chechirwere chinowedzera nekuda kwekuvandudzwa kwezvirwere zvinokonzerwa nehutachiona. Muchiitiko ichi, pane kuunganidza kwezvinonzi acid mucopolysaccharides zvakananga mu stroma yevhavha iyo pachayo. Nezvirwere zvakadaro zvepfungwa yemwoyo, se rheumatism, infective endocarditis, isina-rheumatic carditis, kupera kunogona kubuda sechinhu chinonetsa.

Vhura hwindo revharogi (OOO)

Rudzi urwu rwehutano nderwe chikonzero chekugunun'una kwe systolic mumoyo wemwana. Inozivikanwa nekuvapo kwechidimbu chiduku chiduku pakati pekodzero nechekupedzisira paneri, iyo yakafukidzwa nevhavha inowanikwa kuruboshwe rwetrium. Nekuputsa kwakadaro, kubudiswa kweropa kunoitika mune imwe nzira-kubva kurudyi kuenda kuruboshwe.

Iko kusanganiswa kweiyo nzira kunokonzerwa nevhavha uye chikamu chechipiri. Somugumisiro, gomba rinoumbwa panzvimbo yehwindo. Pasi pemamiriro ehutano, hwindo revhavha rinowanzovhara munguva inenge miviri kusvika kumwedzi gumi nemaviri mushure mokuberekwa. Zvisinei, izvi zvakasiyana-siyana zvakakonzerwa nekugadzirwa kwepfungwa yemapfungwa yemavhudhi hazvitike kuvanhu vose. Maererano nevanyori vakasiyana, hwindo revharo rinoramba richizaruka muna 20-40% (pamwero-mu25-30%) yevanhu vakura.
