A naʻau kiwikā o: ka hana no ke kūapoʻana a me ka hiki mai

Ke kanaka naʻau i eha cavities. Kēlā me kēia no ia ua pili ma kūikawā lua - kiwikā. Ka mea, Pono, e kūhōhō i ke koko a hiki i na keena kōā kaulike. I maʻi o ka naau kiwikā, e noi mai ana kōkua cardiologist. I kekahi manawa, e hoʻopau i ka pathology,ʻoki kino ka pono. Maʻi kiwikā i hoʻomākaukauʻia alakai i circulatory ole. Inā i hana e ia, i ka pathology ke alakai i ka make.

He aha ka naau kiwikā?

Heart kiwikā e pono e hōʻoia 'hoʻokahi-ala koko pono mai kekahi aeea i kekahi. Ka mea, iloko o ka pahale loko, ahu iho o ke kino - ka endocardium. Cardiac kiwikā lawelawe 'ana window ma waena o nā cavities. Mahalo iā ia, ke koko kahe mai kekahi keʻena i ka 'ē aʻe like pono. Valvular i hoʻomākaukauʻia ninoieo o na kēia mau eiiiiiaiou:

1. Ke annulus fibrosus.
2. Muscle'aʻaʻa a kāʻei.
3. Chord.

Mau hale a pau loa imua i loko o nā mea a pau kiwikā. Fibrotic komolima a me i pohā ma waena o nā cavities kuahene ka naau kapiliia. He ua poe e anuanu laholio a me ka collagen olona. Ka nohona kiwikā puapua i e pono ai i mea e hōʻoia 'kona weheʻana i ka manawa o ka systole. Koko ua kiola mai ka kiʻekiʻe-puʻe keʻena o ka naau i kekahi. I ka mea, aole pili pono i kekahi i kekahi, i ka nohona kiwikā puapua i manawa e slam. Chord - he connective'aʻaʻa auka e paa ai. Ka mea, hoʻohui i ka nohona kiwikā i ka papillary nāʻiʻo o ka naau. Kā lākou hana - kaulike i ka pa apŘ ma waena o nā puka.

ʻano likeʻole o ka naʻau kiwikā o

Aia nō 2 ke ano o ka nohona kiwikā o: ka atrioventricular a me ka semilunar. First - i interconnection ma waena o nā keʻena. Semilunar kiwikā mea e pono ai e malama pono koko i loko o na moku nui o ka naau - ka aorta a me pulmonary artery. Ma ka atrioventricular puka loaʻa nā kēia mauʻano o ka nohona kiwikā o:

1. Mitral.
2. Tricuspid.

Mitral naau kiwikā hoʻohuiʻia ka atrium hema a me ka ventricle. Ua ninoieo o 2 eheu. Tricuspid kiwikā o ua aia ma ka palena o ka akau naau keʻena. Like ka hema atrioventricular puka, ka mea, he ekolu puapua. Ke koko EII ni mai o ka naʻau i nā ipu a pau o ke kino, nele ka aortic naau kiwikā. He ua 3 pā: akau, haʻalele a hoʻi. I ka puka o ka pulmonary kumu ua manaʻo ma ka mākeke, mai ka atrium akau. I mea e hana i ka poe liilii, a me ka nui holo, pono e kaha i ka hana o nā mea a pau kiwikā. Poino i kekahi o ia hiki aku ai i ka naʻau ole.

Maʻi o ka nohona kiwikā nakeke

Valvular naau kiwikā i hoʻokuleana i ka likeʻole nā palapū. Ma kekahi hihia i ka hewa 'ole o nā lua ma waena o nā keʻena. Kēia Hōʻike i ke alo o congenital malformations o ka naau, i mea i hanaʻia i ka lepe puke nā loko ma ka fetus. No ka mea anomalies komo:

1. Ventricular septal kina.
2. Palapala Sila Nui ductus arteriosus.
3. Atrial septal kina.
4. Aortic a pulmonic stenosis.

Ma waho aʻeo i ka nohona kiwikā mā hiki e malama hou i na ipu a ka papa kuhikuhiE koko, i ko lakou hewa wahi,ʻaʻohe keena o ka naʻau, a no laila, ma luna o .. Ma kekahi mau hihia, diagnosed he huihui 'ana o kekahi mau mea hewa.

Maʻi o ka nohona kiwikā nakeke hiki ke loaa. Lakou ana ana ma ke kāʻei kua o ka maʻi infectious naau maʻi, systemic hoʻoʻino keʻano o ka hanaʻana. Ke kumu nui no ke kahua o ka mā nā: endo- a me ka myocarditis, rheumatic kuni, atherosclerosis, etc. By loaa kāna hana nā stenosis a me insufficiency o ka nohona kiwikā o ... Mau maʻi pinepine i diagnosed ma ka opiopio, a mawaena ae-elemakule nā mea maʻi.

Nāʻikepili no kaʻoki kino

Inā 'ōlelo ma waena o cardiac cavities ua wawahiia, e pono e puku i ka naʻau kiwikā. I ka hana, e kōkua i ka pale i ke kūpono 'ana o circulatory ole. Oiaʻoki kino - keia mea he hana nui i akoakoaia wale i nā nohoʻana mai i lawe mai ai ia. Aia nō i ke kēia nāʻikepili noʻoki kino:

1. Kāheaʻia kiwikā insufficiency. Wehewehe aku i loko i ka lau i nawaliwali, a hiki wawe ka extensible.
2. Stenosis o ka nohona kiwikā. Ua mea e puka i ka weheʻana ma waena o nā keʻena o ka naau.

Prosthetics ua hana i ka hihia ma ka nohona kiwikā o ka loa hoʻopōʻino'aʻaʻa, a hoihoi kona 'ole mea i hiki. Ma mau, ka mea, ua ike ia ma nā mea maʻi me ka loa stenosis. ʻoki lāʻau lapaʻau lapaʻau mea pono ina ka hoʻomanawanui i na hoailona o ka naau ole i diagnosed loa. Symptoms o keia kulana nā: pokole o ka hanu i koena, syncope, angina. Nō hoʻi, hope o ka nohona kiwikā hua ina kona puka ua hou oi ma mua o 50% a me ka emi o 1 knm. Prosthesis hanaʻia i loko o ia mau hihia a pau he mea calcification o na leaflets a papillary nāʻiʻo.

He aha ke kumu naau kiwikā insufficiency?

Kiwikā insufficiency e hoʻomōhala ana i ma luna o ke kāʻei kua o ka maʻi naʻau maʻi. Ua hiki aku i ka loli i loko o ke koko pele a me ka regurgitation - e hoole haalele. Ole e diagnose ka wā o ka naau kiwikā 'aʻole i pani loa. Ma keia hihia, ke lau e emi laholio. Ma ka hapanui o na hihia, he pono ole aortic a me ka mitral kiwikā.

E hookupaa i ka naau hana valvuloplasty. I loa hoopii, he nohona kiwikā prosthesis. Aortic insufficiency hiki aku ai a hiki i ka hoi ana mai o ke koko, kiola ia i loko o ka ventricle hema. E like me ka hopena o kēia keʻena o ka naʻau i nā Hoʻonui i ka pono a me ka haalele i kona contractility. Ole o ka mea mitral kiwikā o ua wehewehe aku ma ka regurgitation o ke koko i loko o ka lua o ka atrium hema. Kēlā me kēia no kēia mau pathologies alakai i ka naʻau ole.

Ano o kaʻoki kino

He aha ina o ka pōʻino, ua make naau kiwikā? Ke hana ua hana ia ma na hihia o na hiohiona dysfunction o ke kino. Inā naau ole ua compensated, he makeʻe kulana Inc. Maʻi o ka nohona kiwikā i hoʻomākaukauʻia i nāʻikepili o prosthetics pono ole. Ma kekahi hihia i ka pilikia hiki ke eliminated me ka hoʻokomo 'ia' ana o ke pakuiia auanei lakou. No kaʻoki lāʻau lapaʻau kaʻina hana ma luna o ka naʻau nā ka penei:

1. Hoʻonui valvuloplasty. Paa ana no ka hoʻonui i ka hou kiwikā stenosis.
2. Annuloplasty. Ua mea e hoihoi mai i ka haka ai ma ka mea o ka nohona kiwikā kākoʻo apo. Ke PAaIEN no keia hana o ke anoe o ka lua ma waena o nā keʻena, kena ae la e ka ole.
3. Prosthetic naau kiwikā - ua lawe mai i loko o hihia o ka poho a me calcification o na leaflets.

Ke koho ana o kaʻoki kino hilinaʻi nui ma luna o ka oolea o ke kina, i ka makahiki a me ka nui ana o ka hoʻomanawanui.

'ana i kūpono valvuloplasty

Ka manawa "valvuloplasty" pili i nā hana likeʻole ma luna o ka nohona kiwikā o ka naau. Oiaʻoki kino ua hana e like me ka congenital anomalies kino, a ma ka hihia o ka lilo ana kina. Valvuloplasty ua hana, ina he mea stenosis paha insufficiency kiwikā me ka poho o kona 'ole. Nō hoʻi, i kēia hana o kaʻoki lāʻau lapaʻau lapaʻau ua hana ia ma ke alo o ka contraindications i prosthetics.

Ka loa, he pono ole cardiacʻoki kino o aortic stenosis a haʻalele atrioventricular hamama ua manaoia e hoʻonui valvuloplasty. Ua ninoieo o ka kūikawā uea i hoʻolaunaʻia ma ma ka femoral artery. A hiki i ka Tube kīnā ka nohona kiwikā hamama, he hoʻonui hoolilo ma kona hope, ea ua injected. Mahope, i ka catheter ua wehe. Ke hana ua hana ma lalo o ka hooponopono ana angiography. Ua 'Aʻole e koi mau anesthesia, a hoʻohui i ka hoʻomanawanui i ka ventilator.

Ma kekahi mau hihia, stenosis commissurotomy hana. , Ae waiho nei ma ka dissection o fused leaflets.

Annuloplasty ua hana ka wā o ka nohona kiwikā ole. Ke PAaIEN o ke anoe o ka puapua ole ā 'inoʻino kekahi i ka ke aloha. Ke surgeon Nāna e koho i kekahi kākoʻo komolima nui koi 'ia, a fixes ia i ka endothelium ma ka mea o ka nakaka.

Prosthetic naau kiwikā o

Ka hana e puku i ka naau kiwikā o ua hana ma hou i ka atrioventricular orifice i 1.5 knm, aortic -. 1 knm e hoʻohana likeʻole mea like prostheses. Ma kekahi mau hihia, e hoomanawanui i transplanted naau kiwikā holoholona - puaʻa a me na bipi wahine. Ua Ua manaoio aku i ka pilikia o ka rejection o ia prostheses mea haʻahaʻa ma mua o kemikala mea. Kekahi koho o ka transplantationʻoki kino pulmonary kiwikā ma wahi o ka poino aortic orifice. A like ke kaʻina hana no ua hana wale ma kaikaina hoʻomanawanui iki mai, no ka mea pili i ka technically apau iʻoki lāʻau lapaʻau kaʻina hana.

Life ma hope o ka naauʻoki kino

I loko nō o ka mea i cardiacʻoki kino i manaoia risky, ka mea, he pinepine ka wale ala, e hoola i ke kanaka i ka ola. Ma hope o ka prosthetic kiwikā ikaika aku e hooponopono ana o ka hoʻomanawanui pono. Hoʻomanawanui iki mai undergoingʻoki kino e lawe ka lapaʻauʻia no ke ola, ke koko thinning. lāʻau "Warfarin" pili ia i ka ai '. He mea pono e pale aku i ke kahua o ke koko clots ma kaʻimi hoʻopunipuni kiwikā.
