Gusana agafunika k'umwanya w'aorta no gusimbuza agafunika k'umwanya w'aorta

Kubaga agafuniko k'umutima gakuru no kugusimbuza agafuniko k'umutima gakuru ni uburyo bwo kubaga umutima. Bikorwa mu kuvura agafuniko k'umutima kakomeretse cyangwa karwaye. Agakombe k'umutima gakuru ni kamwe mu mafumbiro ane agenga imiterere y'amaraso mu mutima. Kari hagati y'icyumba cyo hasi ibumoso cy'umutima n'umusemburo mukuru w'umubiri, witwa aorte.

Ibikorwa byo gusana valve ya Aorta no kuyisimbura bikorwa mu kuvura indwara ya valve ya Aorta. Ubwoko bw'indwara za valve ya Aorta bishobora gusaba gusana valve cyangwa kuyisimbura birimo: Gusubira inyuma kwa valve ya Aorta. Valve ya Aorta ntisa neza, bituma amaraso asubira inyuma mu cyumba cyo hasi cy'umutima w'ibumoso. Icyo ari cyo cyose kibangamira valve ya Aorta gishobora gutera gusubira inyuma. Rimwe na rimwe, umwana avuka afite valve ya Aorta ifite ishusho idasanzwe itera gusubira inyuma. Kugabanuka kwa valve ya Aorta. Ibyiciro bya valve ya Aorta, bizwi nka cusps, birakomera kandi bikaramba, cyangwa bikabana. Valve iragabanuka cyangwa ntikingura neza. Ibi bigabanya cyangwa bikabuza amaraso kugenda. Kugabanuka kwa valve ya Aorta bishobora guterwa n'indwara y'umutima ibaho kuva ku ivuka cyangwa na zimwe mu ndwara zibangamira valve y'umutima. Ibindi bibazo bya valve ya Aorta bibaho kuva ku ivuka, bizwi nka uburwayi bw'umutima bwavutse. Bamwe mu bana bashobora kuvuka bafite valve ya Aorta ibura umwanya wo gufungura cyangwa ifite ibyiciro bibiri bya valve aho kuba bitatu. Uburwayi bw'umutima bwavutse bushobora kandi gutera valve kuba ifite ingano cyangwa ishusho itari yo. Ushobora kuba ukeneye kubagwa valve ya Aorta niba indwara ya valve yawe igira ingaruka ku bushobozi bw'umutima wawe bwo gutera amaraso. Niba udafite ibimenyetso cyangwa niba uburwayi bwawe buri hasi, itsinda ryawe ry'ubuvuzi rishobora kugutekerezaho gukora isuzuma buri gihe, guhindura imibereho n'imiti. Ariko uburwayi bwinshi bwa valve ya Aorta amaherezo bukeneye kubagwa kugira ngo hagaruke ibimenyetso kandi hagororwe ibyago by'ingaruka mbi nko kunanirwa kw'umutima. Icyemezo cyo gusana cyangwa gusimbuza valve ya Aorta yangiritse gishingira ku bintu byinshi, birimo: Uburemere bw'indwara ya valve ya Aorta, bizwi kandi nka icyiciro cy'uburwayi. Imyaka n'ubuzima rusange. Niba kubagwa ari ngombwa kugira ngo hakorwe indi valve cyangwa uburwayi bw'umutima. Muri rusange, ababagisha bagira inama yo gusana valve iyo bishoboka. Bigabanya ibyago by'indwara, bikarinda valve y'umutima kandi bishobora gufasha umutima gukora neza. Igisubizo cyiza gishingira ku ndwara ya valve ya Aorta, ndetse n'ubuhanga n'uburambe bw'itsinda ry'ubuvuzi. Ubwoko bw'ubuganga bwo kubaga valve ufite biterwa n'imimerere yawe bwite. Urugero, bamwe mu bantu bafite indwara ya valve ya Aorta bashobora kuba batakwiriye kubagwa umutima ufunguye kubera ibindi bibazo by'ubuzima, nko kurwara ibihaha cyangwa impyiko, byatuma ubuvuzi buhinduka ikintu gikomeye. Itsinda ryawe ry'ubuvuzi rirakwereka inyungu n'ibyago bya buri gisubizo.

Ubuvuzi bwose bufite ibyago. Ibyago byo gusana no gusimbuza umuvure wa aorte biterwa n'ibintu byinshi, birimo: Ubuzima bwawe muri rusange. Ubwoko bw'ubuvuzi bw'umuvure. Ubuhanga bw'abaganga n'abandi bakozi bo mu rwego rw'ubuzima. Kugira ngo tugabanye ibyago bishoboka, ubuvuzi bw'umuvure wa aorte bugomba gukorwa muri centre ifite itsinda ry'abaganga b'inzobere mu bijyanye n'umutima kandi bafite ubunararibonye muri ibyo bikorwa, kandi bakora ubuvuzi bw'umuvure wa aorte. Ibyago bishoboka byo gusana no gusimbuza umuvure wa aorte bishobora kuba birimo: Gukura amaraso. Ibibyimba by'amaraso. Ikibazo cyangwa kunanirwa kw'umuvure wasimbuwe. Gukubita k'umutima hadahuje umuvuduko, bizwi nka arrhythmias. Amazi. Impinduka mu bwonko.

Mbere y'uko bagukorera igikorwa cyo gusana cyangwa gusimbuza umuvure wa aorte, itsinda ry'abaganga bazakwitaho rizakubwira ibyo utegereje mbere, mu gihe cyo, no nyuma y'igikorwa, ndetse n'ibyago bishobora kuvuka. Mbere yo kujya mu bitaro kubagwa umuvure w'umutima, ganira n'ababitaho ku bijyanye n'igihe uzamarayo mu bitaro. Muganire ku bufasha ukeneye igihe uzaba ugarutse mu rugo. Ntuzuzagere kubabaza ibibazo uba ufite ku bijyanye n'icyo gikorwa.
