Mwoyo vharafu: zvipenyu zviri regedhi

The vharafu midziyo mwoyo anoita chinokosha basa kuunza kwakakodzera kweropa. Mumwe mwoyo vharafu (dzinokwana ina), synchronously kuzarura uye mukuvhara, kunotadzisa kufamba kweropa aibuda mune neizvi negwara. Kuti anotipa kusachinja-chinja hwakakwana uye yakakwirira nemazvo yose mashandiro ari nechepakati nhengo dzemuviri.

Kana tikaenzanisa ari cardiac kamuri resuwo, mwoyo vharuvhu chinoita basa pamapapiro ake. Mumwe nomumwe wavo ane pachake zvachiri uye chinangwa. Kutsemuka mwoyo vharafu rinoshandiswa kuti nokuvhara pamusuo yeropa. Anatomically, inoitwa mapapiro zvitatu zvakafanana nomwedzi. Kana kuruboshwe ventricle kwemoyo, ichi rutapudzo vharafu kunoita ropa riyerere kupinda yeropa.

Mitral vharafu kuva clamshell chimiro, iri pakati ventricle kuruboshwe uye atrium, pamukova chaakanga anovhara, nokudaro zvichiita rimwe neizvi mirayiridzo ropa kuyerera. Flasher ake zvizere nemasiraidhi akapendwa ventricle kuruboshwe.

Tricuspid vharafu kwomwoyo, kunonziwo tricuspid yaiva pakati ventricle uye atrium uye kurudyi, sezvo zviri pachena kubva zita raro, ane tambo yakakoswa mamiriro. Pachena mamiriro, chobudira ropa kubva kurudyi atrium kupinda ventricle mhango, mumwe zvekupfakira wakakwana izvo anoita tsandanyama marwadzo maitiro, mauri vharuvhu kuvhara kunoitika. Ndezvipi chinonditadzisa neizvi kufamba kweropa uye nechokwadi kuparadzirwa kwayo mugwara.

Pulmonary vharafu, riri pana mugamuchiri mazano womuviri uyu, dzinovimbisa kufamba ropa inoyerera kubva kurudyi ventricle kusvika pulmonary arteries. Ndiwo vakawanda marongerwo uye chinangwa dzichipfekeka pamusoro cardiac valvular midziyo. Saka zviri pachena kuti ishande yose kweropa hurongwa musimboti muviri chete zvinogoneka ane kumeso uye akakwana kushanda zvipenyu mashandiro.

A maitiro chepfungwa mavharuvhu ndechokuti vari pasi chenguva zvokuimba basa vari pasi kumusoro zvinorema. Zvinofungidzirwa kuti anopfuura makumi manomwe makore eupenyu kutenderera mavharuvhu kuti zvakawanwa - the kuvhara anopfuura mabhiriyoni maviri nguva. Kazhinji izvi zvinoita kuti pathologies siyana. Petals (ichibhabhamisa) noutano mavharuvhu dzakaonda uye zvikuru kusanduka jira akakwana geometric chimiro. Sezvingatarisirwa, kwakadaro jira iri pachena kupfeka. Mukuwedzera, chirwere kazhinji zvinogona kukonzerwa pakupona. The mavharuvhu anogona kukuvaradzwa uye akuvadza somugumisiro rakafukidza rheumatic kurwisa, zvirwere zvakasiyana-siyana, nemagene zvikonzero, nokuda zera-ukama kuchinja, yomwoyo , uye muzvizhinji nezvimwewo zvinhu.

izvi zvose zvinogona kukonzera stenosis (kuderedza pamusoro Inlet) kana kutadza (ane kukwana kuvhara zviri ichibhabhamisa). Dzimwe nguva zviitiko zvakadaro kungada kuvhiyiwa mwoyo vharuvhu iyo inoda kudzorerwa kana kutsiviwa. Kunyange yazvino uye zvinhu zvinoita kuti tiite kudaro kunzwisisa uye kurayira nzira rurefu chaizvo mukana chokubudirira, ngozi achiri yakakwirira chaizvo.

The inonyanya nhasi zvinoitiswa pakuvhiya vavakezve "pfava" mwoyo vharafu - the mitral. Kana chakakomba kukuvara vharuvhu yokutsiva nzira kazhinji chete noruponeso murwere. Surgery, nenhumbi nengozi yacho, nokure panyaya kubudirira chero yokurapwa.
