Mitral valve zvinetso zvinetso

The mitral valve chinhu chinonyanya kukosha chemwoyo yemwoyo yevanhu. Mukubatana neizvi, kupesana chero kupi zvayo mukushanda kwayo kunoshatisa hupenyu hwedu nekugara zvakanaka. Tinokurudzira kuziva pamusoro pekugadzwa kwemaster valve, uyewo nezvekukanganisa kunogona kuitwa mubasa rayo, zviratidzo zvavo nemigumisiro. Iniwo ndinoda kuziva kuti, kana pane zviratidzo zvekuti basa re "tsanangudzo" iyi yemutsipa wepanyama rinoputswa, zvinodikamwa kushanyira mutori wenhau, iyo inobatsira kutsvaga chirwere chinogona kuitika pakutanga.

Basa re mitral valve mubasa romwoyo wemunhu musungo

Ivhavha yacho ishizha rinokosha rinobatanidzwa uye riri kurutivi rworuboshwe rwemoyo wemunhu. Iyo inodzivisa kupesana kwekuyerera kweropa kuchipinda kuruboshwe rweatrium kubva kuruboshwe kuruboshwe panguva yekusagadzikana kwemyocardium. Apo mwoyo wako wakakwana zvakakwana, iyo valve, inodarika chidimbu chinodiwa cheropa, inovhara. Kana mabheji atanga kuvhara zvakasimba, mwoyo wakatambanudzwa uye unofungidzirwa, iyo inoguma ichitungamirira kuvhiringidzi mubasa rayo. Kazhinji kacho munharaunda iyi pane zvirwere zvakadai se mitral valve kusimbisa (kana kuparara) uye kusakwanisa kwayo. Tinokurudzira kujekesa pane imwe neimwe yezvipupuriro mubasa remuviri wemwoyo.

Prolapse

Inopera ye mitral valve, iyo ndiyo migumisiro ye compaction, inoitika kakawanda. Chirwere ichi, sekutonga, hachina kumira. Zvisinei, zvinoitika kuti inofambidzana nekupfupika kwemhepo, marwadzo uye kuwedzerwa kwemoyo.

Pane zvinhu zvakawanda zvinowedzera dambudziko rekupera. Izvi zvinosanganisira zvikonzero zvinotsanangurwa pasi apa.

1. Pauro. Muvanhu, chirwere ichi chinowanikwa kakawanda kupfuura pane vamiririri vehafu yakanaka yevanhu.
2. Zera. Ngozi yekukura mitral prolapse inowedzera zvikuru nezera.
3. Nhoroondo yemhuri. Kana umwe wehama yako akatambura nechirwere chakadai, ipapo mikana yekuitika kwayo inowedzerawo.
4. Zvisizvo zvisiri izvo (kuberekwa kana kuwanikwa kuchinja).

Mitral insufficiency

Kune miviri miviri ye mitral valve insufficiency: yakaoma uye isingaperi. Yokutanga inokonzerwa nekukuvadzwa kwemapurisa, mapurisa, maitiro emapuroni anokonzerwa nemakumbo emaroto, infective endocarditis uye kukuvara kwakasiyana-siyana. Chimiro chisingagoneki chinogona kuva chikonzero cherheumatic kukuvara kumutsipa wemwoyo, zvirwere zve systemic, zvirwere kana hutachiona, zvirwere uye mamwe mamiriro.

Chirwere chinyoro chechirwere ichi ndechokushaya kukwana kwe mitral valve yediresi yekutanga. Kuonekwa kukuru kwechirwere ndiko kuonekwa kwemheremhere mumoyo. Sezvo mutemo, varwere vanotungamirira hupenyu hunoshingaira uye havana kana kunyunyuta. Nekutral kusakwana kwechipiri chechipiri kana chechitatu kune ruzha mumoyo , kupfupika kwemhepo uye mapapita zvinowedzera panguva yekuita muviri. Chinhu chinonyanya kuipa muupenyu hwehupenyu ndechezvikamu zvechina uye zvechishanu, apo dystrophic inoshanduka mumutsipa wemwoyo inotanga kuitika, uye kushanda kweimwe nhengo kunowedzera semugumisiro wekushungurudzika kwepakati.
