Chii chinonzi Pulmonary Valve? Ngatizvinzwisise zviri nyore!

Funga nezvemoyo wako seimba diki ine makamuri mana. Kuti ropa riyerere kubva mukamuri imwe kuenda kune imwe, panofanira kunge paine magonhi, handiti? Ndizvo zvakaita vharuvhu remapapu. Ndiro rimwe remavharuvhu mana ari mumoyo. Kutaura chokwadi, 'musuwo' unotora ropa risina oxygen kubva mukamuri rezasi rekurudyi remwoyo wako (rinonzi ``right ventricle'') kuenda ku ``main pulmonary artery'', tsinga huru yeropa inotakura ropa risina oxygen kuenda kumapapu. Ropa iri parinosvika mumapapu, rinotora oxygen. Zvadaro, ropa iroro rine oxygen yakawanda rinofamba kuenda kumuviri wese. Saka, unogona kufungidzira kuti zvakakosha sei kuti suo iri rishande nemazvo? Vharuvhu remapapu, pamwe chete nerimwe vharuvhu mumoyo wedu, ``aortic valve'', pamwe chete zvinonzi ``semilunar valves'' . Izvi zvinodaro nekuti maflaps (senge magonhi) ari pamavharuvhu aya akaumbwa secrescents. Aya mavharuvhu ecrescent anodzora kuyerera kweropa kubva mumakamuri epasi (ventricles) emwoyo wedu kuenda kumidziyo mikuru yeropa (artery). Unogona kunzwawo vachinzi Pulmonic valve. Ose mazita acho anoreva chinhu chimwe chete.

Saka vharuvhu iyi yemapapu inoitei chaizvo?

Basa guru revharuvhu iyi yemapupa, sezvatakambotaura, nderekudzora kuyerera kweropa risina mweya kubva ku ventricle yekurudyi yemoyo kuenda ku tsinga huru yemapupa. Ngatitarisei kuti izvi zvinoitika sei zvakadzama:

• Nguva dzese mwoyo wako uchirova, vharuvhu iyi yemapapu inovhurika nekuvharika, semusuwo .
• Kana ventricle yako yekurudyi yavharika (izvi zvinonzi "systolic phase" mukurapa), vharuvhu yemapapu inovhurika. Apa ndipo panotanga kuyerera ropa richibva mumoyo, richienda kumapapu.
• Zvadaro, kana mwoyo 'wazorora' kwenguva yakati (izvi zvinonzi "diastolic phase" kana kuti relaxation phase), vharuvhu yemapapu inovhara. Izvi zvakakosha zvikuru. Nekuti kana ikasavhara seizvi, ropa rakaenda kumapapu rinogona kudonha richidzokera mumoyo. Izvozvo hazvina kunaka.
• Saka, kana vharuvhu iyi yavharwa ndipo panozadzwa ventricle yekurudyi neropa rainoda kupwanya nguva inotevera.

Funga nezvazvo sepombi yemvura. Unoivhura kana waida wonwa mvura, wozoivhara kana wapedza. Kana zvisina kudaro, mvura yacho inosara isina simba. Vharuvhu yemapapu inodzorawo kufamba kweropa nenzira imwecheteyo.

Basa rakakosha revharuvhu yemapapu mukuita kwaRoss

Pamusoro pekudzora kufamba kweropa nguva dzose, vharuvhu iyi yemapapu inogonawo kuita rimwe basa rakakosha. Kureva kuti, inogona kushandiswa senzira yekutsiva kana imwe vharuvhu inokosha mumoyo medu, iyo `(vharuvhu yeaortic)` ikabatwa nechirwere uye isingashande nemazvo. Izvi zvinonzi `(maitiro eRoss)` . Uku kuvhiya kwakaoma zvishoma. Kunoitwa mune vamwe vana nevakuru vari pasi pemakore makumi matanhatu vane `( Chirwere cheAortic Valve )`. Mukuvhiya uku, chiremba anobvisa `(vharuvhu yeaortic)` yako ine chirwere uye anoitsiva nevharuvhu yako yemapapu ine hutano. Zvadaro, vharuvhu yemapapu kubva kune mumwe munhu ( mupi ) inoiswa mauri. Vharuvhu yako yemapapu inotsiva zvakanaka vharuvhu yeaortic nekuti chimiro nebasa rezvose zvakafanana. Ndosaka inogara kwenguva refu.

Vharuvhu iyi yemapapu iri kupi chaizvo?

Izvi zviri mukati memoyo wako. Sezvatakambotaura, izvi zvakafanana nekubatana pakati peventricle yako yekurudyi netsinga yemapapu, iyo tsinga huru inotakura ropa kuenda kumapapu ako. Iri kurudyi rwevharuvhu yeaortic, uye iri pamberi zvishoma, pavharuvhu huru mumoyo.

Chimiro chevharuvhu remapapu chii, ndiko kuti, chimiro, chevharuvhu remapapu?

Vharuvhu yemapapu ine zvidimbu zvitatu zvikuru zve cusps kana kuti flaps. Kuvhurwa nekuvharwa kwezvidimbu izvi kunodzora kufamba kweropa. Zvipfeko zvitatu izvi zvinonzi anterior cusp, left cusp, uye right cusp. Zvipfeko izvi zvakabatanidzwa kune tambo yakasimba zvishoma, ine fibrous inonzi annulus. Kana moyo wareruka (ndiko kuti, panguva ye diastolic phase), zvikamu zvitatu izvi zvinobatana zvakasimba uye zvinovhara vharuvhu zvachose. Izvi zvinodzivirira ropa kuti risayerere richidzokera kumashure kuenda ku right ventricle (regurgitation).

Ndezvipi zvirwere nemamiriro ezvinhu anokanganisa vharuvhu yemapapu?

Chirwere chevharuvhu remapapu chinogona kuitika nenzira dzakasiyana-siyana. Kazhinji, idzi inyaya dzemwoyo dzekuzvarwa nadzo. Izvi zvinoreva kuti iwe kana mwana wako mungave nematambudziko aya pakuzvarwa. Zvisinei, kashoma, matambudziko nevharuvhu iyi anogona kukura gare gare muhupenyu. Izvi zvinowanzo kukonzerwa nezvimwe zvirwere, zvakaita seBP yemapapu . Zvimwe zvezvirwere zvinogona kukanganisa vharuvhu remapapu zvinosanganisira:

• Kupera kweropa mumapapu: Ichi chirwere chemwoyo chinowanikwa pakuzvarwa. Izvi zvinoitika kana vharuvhu yemapapu yemwana isingakure zvakanaka, kana kuti muromo wayo wavharwa nenyama. Izvi zvinoita kuti ropa riyerere kune dzimwe nzvimbo dzemwoyo wemwana. Izvi zvinokonzeraPakuzvarwa, mwana anogona kuita bhuruu ( cyanosis ) (zvichireva kuti oxygen yakaderera).
• Tetralogy of Fallot: Ichi chirwere chemwoyo chinokonzerwawo nekuzvarwa nacho. Chirwere ichi chinokanganisa mwana mumwe chete pavana 2,500 vanozvarwa muUnited States. Muchiitiko ichi, mwana ane zvirwere zvina mumoyo. Chimwe chezvirwere izvi i pulmonary stenosis (kutetepa kwevharuvhu yemapapu netsinga huru yemapapu). Ichi chirwere chakakomba nekuti chinodzikisa huwandu hweropa rine oxygen rinotenderera mumuviri wemwana wese. Vana vane chirwere ichi vachatoda kuvhiyiwa.
• Kuvharwa kwevharuvhu remapapu: Uku kuvharwa kwevharuvhu kudiki. Izvi zvinowanzoonekwawo pakuzvarwa. Zvinowanzoonekwawo kuvana vane Tetralogy of Fallot. Kune nzira dzisinganyanyi kupindira dzinogona kushandiswa kuvhura vharuvhu senzira yekurapa. Vamwe vanhu vangangodawo kutsiviwa vharuvhu. Hazviwanzoitiki kuti munhu akazvarwa aine vharuvhu remapapu rine hutano awane stenosis yemapapu gare gare muhupenyu hwake.
• Vharuvhu yemapapu isina: Ichi chirwere chemwoyo chinokonzerwawo nekuzvarwa nacho. Chinokanganisa mwana mumwe chete pavana 50,000. Chinonyanya kuitika kuvana vane Tetralogy of Fallot. Apa ndipo apo mapepa/maflaps evharuvhu yemapapu emwana anenge asipo kana kuti asingakure zvakanaka. Izvi zvinoita kuti kuvhurika kwevharuvhu kuve kutetepa (stenosis) uye ropa ribude richidzokera kumashure (regurgitation). Izvi zvinoita kuti ropa ridzokere mu ventricle yekurudyi kubva mutsinga huru yemwana kuenda kumapapu (pulmonary trunk). Chirwere ichi chinofanirawo kurapwa achiri mudiki.
• Kudzoreredza vharuvhu yemapapu: Apa ndipo panobuda ropa richibuda nepavharuvhu. Izvi zvinowanzokonzerwa neBP yemapapu kuvanhu vakuru kana chirwere chemwoyo chekuzvarwa nacho. Zvinogonawo kuitika kune vamwe vanhu vakavhiyiwa Tetralogy of Fallot. Izvi zvinoitika kana vharuvhu yemapapu isingavharike zvachose nguva imwe neimwe moyo uchirova. Nekuda kweizvozvo, kana moyo wasununguka, rimwe ropa rinobuda richidzokera mu ventricle yekurudyi kubva mutsinga yemapapu. Vanhu vazhinji vane zviratidzo zvishoma. Zvisinei, vamwe vanhu vanogona kuva nezviratidzo zviri pakati nepakati kana zvakakomba zvinoda kurapwa. Kana rudzi urwu rwekubuda ropa rukaramba rwuripo kwenguva yakareba, zvinogona kukonzera kuwedzera uye kutadza kwe ventricle yekurudyi, pamwe nekuzvimba (edema).

Zvinokwanisika here kurarama usina vharuvhu yemapapu?

Aiwa. Vharuvhu yemapapu chinhu chakakosha chinotumira ropa kumapapu uye chinobatsira kuti ropa riwane okisijeni.Hatigone kurarama tisina vharuvhu inoshanda zvakanaka. Vacheche nevana vane matambudziko makuru evharuvhu yemapapu vanogona kuva nehupenyu hupfupi kana vakasabatwa zvakanaka. Saka, kana iwe kana mwana wako muine dambudziko revharuvhu yemapapu, zvakakosha kutaura nachiremba wenyu nezvesarudzo dzekurapa uye nguva yekurarama.

Ndingachengetedza sei vharuvhu yangu yemapapu iine hutano?

Matambudziko emavharuvhu emwoyo haagone kudzivirirwa nguva dzose, kunyanya ayo aripo pakuzvarwa. Asi, kazhinji, kutevedzera mararamiro ane hutano hwemoyo kunogona kubatsira zvikuru mukuchengetedza mavharuvhu ako nemoyo wako zviri kushanda zvakanaka. Heano mamwe emamwe zvinhu zvinogona kubatsira:

• Rega kusvuta, kuputa fodya, nezvimwe zvigadzirwa zvefodya zvachose. Kumbira chiremba wako kuti akubatsire kurega.
• Deredza kunwa doro , kana kuti rega zvachose.
• Idya chikafu chine hutano pamoyo. (Tichataura nezvazvo mune imwe nyaya!)
• Maekisesaizi nguva dzose sezvinokurudzirwa nachiremba wako. Vanhu vazhinji vanofanira kuita maekisesaizi ane mwero wemaminitsi angangoita 150 pasvondo, akadai sekufamba netsoka.
• Dzora mamiriro ezvinhu akadai seBP yakakwira uye cholesterol yakakwira.
• Inwa mishonga yawakanyorerwa nachiremba panguva chaiyo uye nemazvo.
• Ongororwa nachiremba kanenge kamwe chete pagore.
• Kana uine pamuviri, iva nechokwadi chekuenda kumakiriniki akakodzera ekudzivirira pamuviri uye evakadzi uye uwane rubatsiro rwakakodzera. Kuita izvi kunogona kuderedza njodzi yezvirwere zvemwoyo zvekuzvarwa nazvo mumwana wako achangoberekwa.

Kudzidza nezvemaumbirwo emwoyo wako dzimwe nguva kunogona kukuomera, kunyanya kana iwe kana mwana wako akaonekwa kuti ane chirwere chemwoyo. Ruzivo rwakawanda rwekudzidza panguva imwe chete. Hazvisi nyore kurangarira kuti mavharuvhu api anotakura ropa kuenda kupi, uye kuti chirwere chemwoyo chinokanganisa sei kufamba kweropa. Asi yeuka, chiremba wako anogara aripo kuti akubatsire kudzidza zvinhu izvi uye kukupa ruzivo rwaunoda. Usazeza kuvabvunza chero mibvunzo yaunayo.
