Pulmonary vharafu stenosis

Pulmonary valve stenosis chirwere chevhavha yemoyo chinosanganisira iyo pulmonary valve.

Iyi ndiyo vharuvhu inoparadzanisa ventricle yekurudyi (imwe yemakamuri mumoyo) uye tsinga yemapapu. Iyo pulmonary arteri inotakura oksijeni-isina ropa ropa kumapapu.

Stenosis, kana kudzikira, kunoitika kana vharafu isingakwanise kuvhura zvakakwana zvakakwana. Nekuda kweizvozvo, shoma ropa inoyerera ichienda kumapapu.

Kuderedza kwevhavha yemapurmoni kunowanzo kuvepo pakuzvarwa (kuberekwa). Inokonzerwa nedambudziko rinoitika sekukura kwemwana mudumbu asati azvarwa. Chikonzero hachizivikanwe, asi majini anogona kutora chinzvimbo.

Kudimbudzira kunoitika muvharuvhu pachayo kunonzi pulmonary valve stenosis. Panogona zvakare kuve nekudzikira nguva isati yatanga kana mushure mevhavha.

Iko kuremara kunogona kuitika kwega kana nekumwe kukanganisa kwemoyo kuripo pakuzvarwa. Mamiriro acho anogona kuve akapfava kana akaomarara.

Pulmonary valve stenosis chirwere chisingawanzoitika. Mune zvimwe zviitiko, dambudziko rinomhanya mumhuri.

Zviitiko zvakawanda zve pulmonary valve stenosis zvinyoro uye hazvikonzere zviratidzo. Dambudziko rinowanzo kuwanikwa muvacheche kana moyo uchigunun'una ukanzwika panguva yekuongorora moyo.

Kana iyo vharuvhu yakadzikira (stenosis) iri pakati nepakati kusvika kune yakaoma, zviratidzo zvinosanganisira:

• Kusununguka kwemukati
• Ruvara rweBluish kune ganda (cyanosis) mune vamwe vanhu
• Chido chisina kunaka
• Kurwadziwa pachifuva
• Kufenda
• Kuneta
• Kurera huremu kuwedzera kana kutadza kubudirira muvacheche vane rakanyanya kuvharika
• Kufema kwekufema
• Kufa kamwe kamwe

Zviratidzo zvinogona kuwedzera nekurovedza muviri kana chiitiko.

Anopa hutano anogona kunzwa moyo uchigunun'una kana uchiteerera kumoyo uchishandisa stethoscope. Kugunun'una kuri kupururudza, kurira, kana kutinhira kunonzwika panguva yekurova kwemoyo.

Miedzo inoshandiswa kuongorora pulmonary stenosis inogona kusanganisira:

• Catheterization yemwoyo
• Chest x-ray
• ECG
• Echocardiogram
• MRI yemoyo

Iye mupi anozoverenga kuomarara kwevhavha stenosis kuronga kurapwa.

Dzimwe nguva, kurapwa kunogona kusadikanwa kana kusagadzikana kuri nyoro.

Kana paine zvimwe zvinokanganisa moyo, mishonga inogona kushandiswa ku:

• Batsira kuyerera kweropa kuburikidza nemoyo (prostaglandins)
• Batsira moyo kurova zvine simba
• Kudzivirira kugwamba (kuwonda kweropa)
• Bvisa zvakawandisa mvura (mapiritsi emvura)
• Bata kurova kwemoyo zvisina kujairika uye mutinhimira

Percutaneous balloon pulmonary dilation (valvuloplasty) inogona kuitwa kana pasina zvimwe zvinokanganisa moyo zviripo.

• Maitiro aya anoitwa kuburikidza neateri mune iyo groin.
• Chiremba anotumira chubhu inochinja (catheter) ine bharumu rakanamatira kumagumo kusvika pamoyo. Yakakosha x-ray inoshandiswa kubatsira kutungamira iyo catheter.
• Bhaluni rinotambanudza kuvhura kwevhavha.

Vamwe vanhu vangangoda kuvhiyiwa moyo kugadzirisa kana kutsiva vharuvhu remapapu. Ivhavha nyowani inogona kugadzirwa kubva kwakasiyana zvigadzirwa. Kana iyo vharafu isingakwanise kugadziriswa kana kutsiviwa, mamwe maitiro anogona kudikanwa.

Vanhu vane chirwere chinyoro havawanzo kuwedzera kuipa. Zvisinei, avo vane chirwere chine mwero kusvika chakanyanya vanozonyanya. Mhedzisiro yacho inowanzo kuve yakanaka kwazvo kana kuvhiya kana kubhaluni kuwedzera kuri kubudirira. Kumwe kuberekwa kwemoyo kuremara kunogona kuve chinhu chinokonzera mune maonero.

Kazhinji kazhinji, mavhavha nyowani anogona kugara kwemakumi emakore. Nekudaro, mamwe achasakara uye anoda kutsiviwa.

Zvinetso zvinogona kusanganisira:

• Kusina kujairika kwemwoyo (arrhythmias)
• Rufu
• Kukundikana kwemoyo uye kuwedzera kwerutivi rwerudyi rwemoyo
• Kuyerera kweropa richidzokera mukati chaimo ventricle (pulmonary regurgitation) mushure mekugadziriswa

Fonera mupiki wako kana:

• Iwe une zviratidzo zveplmonary valve stenosis.
• Iwe wakarapwa kana usina kurapwa mapapu emagetsi stenosis uye wakagadzira kuzvimba (kwemakumbo, makumbo, kana dumbu), kunetseka kufema, kana zvimwe zviratidzo zvitsva.
