Kaviri kuburitsa kurudyi ventricle

Kaviri kuburitsa kurudyi ventricle (DORV) chirwere chemwoyo icho chiripo kubva pakuberekwa (kuberekwa). Iyo aorta inosangana neiyo kurudyi ventricle (RV, iyo kamuri yemoyo iyo inopomba oxygen-isina ropa mapapu), pachinzvimbo chekuenda kuruboshwe ventricle (LV, iyo kamuri inowanzo kupomha oxygen-yakazara ropa kumuviri).

Ose maviri epurmonary arteri (ayo anotakura okisijeni-isina ropa mapapu) uye aorta (inotakura okisijeni-yakazara ropa kubva pamoyo kuenda kumuviri) inobva mukamuri imwechete yekupomba. Hapana tsinga dzakabatana nevekuruboshwe ventricle (iyo kamuri inowanzo pomba ropa kumuviri).

Mune yakasarudzika moyo chimiro, iyo aorta inosangana neLV. Iyo pulmonary arteri inowanzo kuve yakabatana neiyo RV. MuDORV, tsinga mbiri dzinoyerera dzichibuda muRV. Iri idambudziko nekuti RV inotakura oxygen-isina ropa. Ropa iri rinotenderera mumuviri wese.

Chimwe chiremara chinonzi ventricular septal defect (VSD) chinowanzoitika neDORV.

Oxygen-yakazara ropa kubva mumapapu inoyerera ichibva kuruboshwe rwemoyo, kuburikidza neVSD kuvhura uye kupinda muRV. Izvi zvinobatsira mucheche ane DORV nekubvumira ropa rine oxygen kuti risanganise neropa-isina ropa. Kunyangwe nemusanganiswa uyu, muviri unogona kusakwanisa kuwana oxygen yakakwana. Izvi zvinoita kuti moyo ushande nesimba kusangana nezvinodiwa nemuviri. Kune mhando dzinoverengeka dzeDORV.

Musiyano uripo pakati pemhando idzi ndiyo nzvimbo yeVDS sezvo ichienderana nenzvimbo yepurmonary arteri uye aorta. Zviratidzo uye kuomarara kwedambudziko kunoenderana nerudzi rweDORV. Kuvapo kwepulmonary valve stenosis kunokanganisawo mamiriro acho.

Vanhu vane DORV vanowanzove nekumwe kukanganisa kwemoyo, senge:

• Endocardial cushion kuremara (iwo madziro achiparadzanisa ese mana makamuri emoyo haana kusimba kuumbwa kana kusavapo)
• Kubatana kweaorta (kuderera kweaorta)
• Matral valve matambudziko
• Pulmonary atresia (pulmonary vheji haina kuumba mushe)
• Pulmonary vharafu stenosis (kudzikira kwepulmonary valve)
• Kurudyi-kuruboshwe aortic arch (aortic arch iri kurudyi pane kuruboshwe)
• Kuchinjika kweakakura arteri (iyo aorta uye pulmonary arteri yakachinjiswa)

Zviratidzo zveDORV zvinogona kusanganisira:

• Wakawedzera moyo
• Moyo kugunun'una
• Kukurumidza kufema
• Kukurumidza kurova kwemoyo

Zviratidzo zveDORV zvinogona kusanganisira:

• Kudya zvakashata kubva mukuneta nyore
• Bluish ruvara rweganda nemiromo
• Kirabhu (kuomarara kwemabhedha ezvipikiri) zvigunwe nezvigunwe (chiratidzo chekupedzisira)
• Kukundikana kuwedzera uremu uye kukura
• Ruvara rwependi
• Kudikitira
• Makumbo akazvimba kana dumbu
• Kunetseka kufema

Kuyedza kuongorora DORV kunosanganisira:

• Chest x-ray
• Ultrasound bvunzo yemoyo (echocardiogram)
• Kupfuudza mutete, wakapfava chubhu mukati memwoyo kuyera BP uye jekiseni dhayi yemifananidzo yakasarudzika yemoyo uye arteri (moyo catheterization)
• Mwoyo MRI

Kurapa kunoda kuvhiyiwa kuti uvhare gomba mumoyo uye utungamire ropa kubva kuruboshwe ventricle kuenda muaorta. Kuvhiya kunogona zvakare kudikanwa kufambisa pulmonary arteri kana aorta.

Zvinhu zvinoona mhando uye huwandu hwekuvhiya hunodiwa nemwana hunosanganisira:

• Rudzi rweDORV
• Kuomarara kwekukanganisa
• Kuvapo kwemamwe matambudziko mumoyo
• Mamiriro ezvinhu emwana wese

Kunyatsoita mwana zvinoenderana ne:

• Kukura uye nzvimbo yeiyo VSD
• Kukura kwemakamuri ekupomba
• Iko iko kweaorta uye pulmonary arteri
• Kuvapo kwemamwe matambudziko (senge coarctation yeiyo aorta uye mitral vharuvhu matambudziko)
• Hutano hwese hwemwana panguva yekuongororwa
• Kunyangwe kukuvara kwemapapu kwakaitika kubva kuwanda kweropa kuyerera kusvika kumapapu kwenguva yakareba yenguva

Zvinetso kubva kuDORV zvinogona kusanganisira:

• Kutadza kwemoyo
• Kuwedzera kweropa mumapapu, ayo asina kurapwa anogona kukonzera kukuvara kwemapapu zvachose
• Rufu

Vana vane moyo uyu mamiriro vangangoda kutora maantibayoti vasati varapwa mazino. Izvi zvinodzivirira hutachiona hwakakomberedza moyo. Mishonga inorwisa mabhakitiriya inogona zvakare kudikanwa mushure mekuvhiyiwa.

Fonera wako mupi wezvehutano kana mwana wako achiita kunge aneta nyore, anonetseka kufema, kana ane bhuruu ganda kana miromo. Iwe unofanirwa zvakare kubvunza mupi wako kana mwana wako asiri kukura kana kuwedzera uremu.
