Cardiology. naau kiwikā - he kanaka ka ola

Healthy naʻau ua kapaia ka ikaika, e hana ana i noke a me ka haʻahaʻa kino. Kona nui hoʻopili like me ka nui o na kanaka lima, a kaupaona ma kahi o elima haneri nā huna. Ma waho aʻeo i kona papa hana e hōʻoia 'maʻamau (lio) koko, ia mea hiki ke hakuloli i ka hoʻololi pono o ka meaola mau.

Hana me he mau-ala EII ni, ka naau hoʻolako i ke koko holo ma ke kino. Ma keʻano o ka muscular pa (septum) ka mea, ua maheleia i halves. Kēlā me kēia hapalua maupaʻa mau keʻena (atria a me ventricles).

Ka'ākau atrium loaʻa ke koko mai o ka pau ana o ka māhele lalo a me luna o ke kino. E like me ka mea tricuspid kiwikā o ke koko hele i ka ventricle akau, a, ma ka malamalama kiwikā kumu ma loko EII ni koko. Oxygenated, ka mea, ua hoouna aku la i ka atrium hema. Mai laila ma luna o ka mitral kiwikā koko hele i loko o ka ventricle hema, i mea ka aortic kiwikā hāʻawi i ke koko ma ke kino. Iai? Oaiaaiea i ke kino o ka oxygen, ka mea, ua depleted, hou i loko o ka atrium akau mai.

Heart kiwikā e weheʻana o kekahi i kekahiʻaoʻao "puka" ma waena o nā keʻena. 'Aʻole wale nō hana e kākoʻo i ka paipai' ana o ke koko i mua, akā, no hoi e ole ai kona hope iho ka neʻeʻana. Healthy naau kiwikā i petals, oia hoi o ka wiwi,'ōlewa palapala maʻamau'aʻaʻa. Ka wā o ka naau, ua nanea wale a me ka ho'ēmi wehe a me ka panina i wahi smoothly.

Birth mā hiki i pathology. Heart kiwikā hiki ke uhi ia me scars a poino like me ka hopena o nā mea palahēhē, rheumatic kuni, hereditary maʻi, naau ho'āhewa wale. Poho i ke kauoha ae la ia ma ka mana o ke kanaka elemakule. Ka poe i kamepiula loa nō i ka mitral kiwikā. A pau keia ia lŘlŘ reguritatsiya (mitral regurgitation), ma a he mea kulu ana o ke koko, mai ka nohona kiwikā i loko o ka aʻe ala ma hope o panina o ka nohona kiwikā. Ma keia hihia, no ka hana ana o ka naau i oi, pili - ka mea, ua imi e pili i ka pono nui o ke koko i loko o ka kino, a compensate no ka ole. Poino i ka naʻau kiwikā a me nā stenosis (hou o ka nohona kiwikā hamama), i loko o ke koko a hele ma ka ino kiwikā. Ma keia hihia, e like me ke kino hoʻomaka e hana paʻakikī e e lawa ke koko ma ka puali ololi e puka. Oia hou hoʻopilikia i loko o ka naʻau hoʻonāwaliwali ia, ka mea e hookomo ana ia e hoonui a me ke kumu likeʻole maʻi.

Ma na hihia a pau, e lawe nui na laau, a ma lalo pono 'inikua hooponopono, me ka naau maʻi kanaka, e ola i ka piha ola. Naʻe, ka mea hana i na ai 'mai i lawe mai i kekahi kanawai paha e nā palapala i ke ola. Ke kaumaha ma muli o ka ana, i ke kahuna lapaau ke koi 'hoihoi hou ia ana paha prosthetic mitral kiwikā. Eia naʻe, ma ka hihia o ka mea deformations a poho ke ola e ole lawe mai i ka makemake hopena. Ma ia he pololei ai paakiki kulana, e pono i ka naau kiwikā o hope. ʻoki lāʻau lapaʻau 'uao ua pono ai ma ka hoouka kaua ana o symptoms o ka maʻi naʻau ole, a me ka nui emi ma ka ejection o ke koko o ka hema ventricle (systolic dysfunction).

Ke? Aeiino? (Hoihoi hou ia ana, ea) o ka nohona kiwikā ua lawe mai me ka mālama 'ana o kona mau naʻau kiwikā. Ma keia hihia, ma hope o ka hana o ka hoʻomanawanui mea,ʻaʻole ma ka pono o ka a eia i? Eaia o ke koko-thinning lapaʻauʻia.

Me ka ikaika,ʻaʻole amenable e hana hou i poino hoonoho i hope (prosthetic) kiwikā. No keia mea, me mechanical (ʻimi hoʻopunipuni) ole liluwelo ('aʻaʻa) prostheses.

Mechanical naau kiwikā mau loa ike loea a me kaʻaʻahu, mai koi hope. Naʻe, ka mea, i ka nui drawback - i mea e pale aku i ke koko coagulation, i ka hoʻomanawanui ma hope oʻoki kino i hoʻokohu 'ia e like medicaments no ke ola.

Liluwelo prostheses i mai chemicallyʻia holoholona naau hapa (lio, bipi a me puaʻa). Ma hope o mea hoʻonoho o ka'aʻaʻa kiwikā prosthesis i ka hoʻomanawanui ua ole i hoakakaia lapaʻauʻia, ke koko thinners. Naʻe, i ka hana o ke ola ana o ka prosthesis mea i kaupalena 'ia i ka manawa, a ma hope o kekahi wā (he umi i ka umikumamalima makahiki) ua luku, kūpono i hiki lua o ka hana.
