Kusakwana kwemaster valve ndeimwe yemhando dzehosha, iyo ine zita rinowanikwa chirwere chemwoyo. Muchiitiko ichi, mabasa e mitral valve anoputsika, uye haasati avhara zvachose, izvo zvinoita kuti ropa risapinde nechokumucheto atrium, apo simba rayo rinowedzera, iyo isiri nzira yakanaka yehutano hwemwoyo uye yehupenyu hwose hwakazara.
Zvinokonzera chirwere chacho
Kubva pamusana pacho kunotarisa kuti kusakwanisa kwe mitral valve kuchakudziridza sei. Pane zvinhu zvakawanda zvinokonzera kuonekwa kwechirwere ichi:
1. Chirwere chechiKristu chinokonzera chinowanzoitika kakawanda kupfuura vamwe. Izvi zvinokonzerwa nekuti panguva yekuzvitakura, zvimwe zvinhu zvisingaiti (utachiona, kushushikana, kuipa kwezvisikwa, miviri, njodzi) zvakakanganisa hupenyu hwemamai huri mberi. Congenital insufficiency ye mitral valve inogona kuva yemhando dzakasiyana siyana:
- myxomatous degeneration;
- anomalies muhutano hwe mitral valve;
- chimiro chekugadzirwa kwetambo dzedononi (makumbo).
2. Zvirwere zvinogadziriswa zvinoshandiswa nekushandurwa muzviputi. Izvi zvinogona kukonzerwa nezvinhu zvinotevera:
- rheumatism;
- kushungurudzika kwakadzikama kwemoyo;
- infective endocarditis ;
- kuporesa kupindira mukurapa mitral stenosis .
3. Kuwanikwa kunokonzera izvo zvisingabatanidzi nekushandura muzviputi zvevhavha. Izvi zvinosanganisira
- misodzi yematope tsvina inobatanidza misoro yemapurisa kusvika pamwoyo mususu;
- kukundwa kwemapurisa emisumbu;
- Kuwedzerwa kwemhete yakaoma pamadziro emoyo, iyo inonzi ring ring.
Chikonzero chekupedzisira chekukundikana kwemaster valve chikonzero chekuputika kwemutsipa wemwoyo, kuwedzera mukati memwoyo, kana kuchinja kwekutaura kwemasvikiro emwoyo.
Zviratidzo zve mitral valve insufficiency
Chiratidzo chokutanga chekuratidzwa kwemaster valve kusakwanira ndiko kuputsa kwemwoyo mafungiro, anosanganisira kuporesa kunetseka. Kusvika pamwero mukuru, izvi zvinoratidzika pasi pemitoro yepanyama, kwete kunyange zvikuru. Kana murwere achiona kushungurudzika kwomuviri wemwoyo paanozorora, ipapo chirwere chinobudirira. Uyezve, kune kutya kunononoka, kuzvimba uye kunetseka mukodzero yepamusoro ye quadrant, iyo inokonzerwa nekuwedzera kwechiropa. Chiratidzo chisina kutarisirwa chekushaya kukwana kwe mitral valve chirwere chakaoma nekubuda.
Pakati pezviratidzo zvakajeka zvinoratidza kuti hapana chirwere chemwoyo chakakomba, chinyorwa:
- cardialgia (kugomera uye kumira, kazhinji-kuomesa marwadzo munharaunda yemwoyo);
- pastose ezasi pasi.
Kurapa kwechirwere
Nzira yekurapa mitral valve kusakwanira inoenderana neshato iyo chirwere chacho chiripo. Pachigamba chekutanga, kurapwa kwemishonga kunoitwa, pachipiri uye chechitatu - chirwere. Chikamu chechina nechishanu chakakosha, uye chirwere chemuviri hachina kugadzikana, naizvozvo havasati vasarudza kuvhiyiwa.
Mukushanda, basa rekuvhara mavhareji remitral rinodzorerwa. Kuti uite izvi, deredza mhete yakasungirirwa nekodzero inokosha yakasimba ring. Munyaya ye calcification uye fibrosis, chigadzirwa chemagetsi kana mashandisi evhavha inoiswa. Nguva yekugadziriswa kwemashure kunotarisana nemamiriro emurairo. Izvi zvinotarirwawo kune chiremba anoenda, anorondedzera nzira uye kugadzirira.
Nokudaro, zvinogona kuonekwa kuti kusakwanira kwemitral valve chirwere chakaoma icho chinonetsa kurapa muchikamu chechipiri kusvika kunechishanu, saka, neyokutanga zviratidzo, kunyange kure kure, chiremba anofanira kubvunzurudzwa pakarepo, sezvo kusinganzwisisiki uye kushaya kukwana kwe mitral valve zviri nyore kurapa .
