Aortic kiwikā o: ka 'ole, hanaʻano papa hana. Stenosis a me insufficiency o ka aortic kiwikā o

Aortic valvular naau maʻi ua ana wehewehe aku ma ka kuai ano, a hoikeia'ku auanei clinically wale i ka wa elemakule. Lākou alo hiki i loa hemodynamic ka haunaele. Ke oolea o ka maʻi mea e loli ka hoohuoi ana kiwikā i irreversible.

Ka naau o ka puha kino a he eha keʻena. Ka hema a me ka pono halves kaawale ma i pohā i i ole me ka ho okumu, nae, ma waena o ka atrium a me ka ventricle ma kēlāʻaoʻao mai o ka puka i hoʻolako pono me ka nohona kiwikā. Mau hale e ka mea e hiki ai e hooponopono i ke koko holo, pale regurgitation, oa aʻe ninini.

Ma ka haʻalele ma laila ka mitral kiwikā he a mau kiwikā, a ma ka akau - ka tricuspid, ka mea, he ekolu leaflets. Kiwikā i hoakaka ia tendon lopi, a hōʻoiaʻiʻo i ka puka i loko o hoʻokahi wale ao ao. Kēia 'ano ua ālai backflow o ke koko i loko o ka atrium ninini. Ma o ka hoʻololi o ke ventricle hema i loko o ka aorta, aortic kiwikā o laila. Kona kuleana pili i - e hoolako i kekahi i kekahi-kapakahi paipai 'ana o ke koko i loko o ka aorta. Ma kaʻaoʻao'ākau ka hoi he nohona kiwikā o ka pulmonary artery. He mau nāʻoihana i kapaia "semilunar" ka mea, kela mea keia mea i ekolu leaflets. Kekahi abnormality, e laʻa me, calcification o ka aortic kiwikā, hele aku ai i ka hoʻohuikau 'ana i ke koko neʻeʻana.

Keʻano papa hana o ka aortic kiwikā o

A nui kūlana ma ka holo Radio ka aortic kiwikā. Ka puapua i silaia ai hoopokole - keia mea kekahi o ka papa kuhikuhiE pathologies. Ua lilo ke kumu o hemodynamic instability. I ka hana ana o keia hapa o ka kino - e hōʻoia i ka paipai 'ana i ke koko mai ka atrium hema i loko o ka ventricle, pale regurgitation. e wehe i ka nohona kiwikā iloko o atrial systole, ma i ua kuhikuhi manawa koko ma ka aortic kiwikā i loko o ka ventricle. Eia, i ka puapua i paa i ka ole nana e hoole ninini.

Ma ka manawa o ka hanana hiki ke hōʻike 'congenital naau mā (aortic kiwikā a me nā ē aʻei) a me ka loaa. Nā loli lakou aloha ole wale na kiwikā, akā, me ka naʻau pa. pinepine Congenital mā i hui, e ka mea paakiki e diagnose a me ka hana.

Aortic kiwikā stenosis

Pathology komo hou ana o ka hoʻololi o ke ventricle hema i loko o ka aorta - e loli ai i ka nohona kiwikā leaflets a me kā lākou a puni nā'aʻaʻa. Kēia maʻi, e like me ke ana helu nā hoailona, oi, he pono ole i ka poe kane a pau. Hoailona iho la i o na paia o ka aorta a me ka aortic kiwikā o ua nō kāu me rheumatic a me ka degenerative lesions pili. Nō hoʻi, e like me ka etiologic konohiki ke hana endocarditis, rheumatoid arthritis. Mau maʻi ka hopena kuʻi nukeliu o na slats, hiki hoemi lākou ka hoʻoneʻe, a me ka nohona kiwikā hiki ole e loa haumāna i loko o systole o ka ventricle hema. I ka wa elemakule, ke kumu no ka holo pono o pinepine atherosclerosis a me calcification o ka aortic kiwikā leaflets.

E like me ka hopena o ka hou o ka aortic orifice loaʻa nā mea hou i loko o hemodynamics. Ka mea, i malama ia ai ka degere o ka stenosis ua kaheaia ma ka - hoemi'āpana e oi aku mamua o 50%. Ua hiki aku i ka mea ana i keʻano piʻina o ka aortic kiwikā puʻe loli - aortic puʻe koe maʻamau, akā, ka mea maoli i loko o ka ventricle hema. Mahuahua waiū ma luna o ka paia o ka ventricle hema hele aku ai a hiki i ke kūpono 'ana o ka uku' hypertrophy,ʻo ia hoʻi, i kona ai hanaʻia naʻe. A laila pilikia diastolic hana a me ka mea e hookomo ana i ka mahuahua ma ka puʻe i loko o ka atrium hema. Hypertrophy hiki aku ai i ka mahuahua o oxygen koi, nae, o ka mahuahua myocardial nuipa a hoike no ka mua koko lako, a hiki i ka emi ma concomitant pathologies. Ua hiki aku i ka ulu ana o ka naau ole.

I ka kuʻina kakahiaka nui o ka loli ana o aortic kiwikā hiki 'aʻole i hoike ia. Lapaʻau loli ana ka wā wehe i ke kapu a hiki i 2/3 o ka maʻamau. I loa exertion hoʻomanawanui iki mai hoʻomaka e hoʻopilikia i ka eha, IIeEeAIEUIeXAIIUE ma ke kua o ka breastbone. Pain maʻi pale i loko o pohihihi keia hihia, i ke pili me ka poho o ka ike paka i aie i ka systemic vasodilatation. Ho okumu ana o pulmonary hypertension alakai i ka pokole o ka hanu, a initially e pili ana me ka haawe wale, akā, laila, he mea i maha. Protracted maʻi papa i ke kumu o ka maʻi naʻau ole. Pathology ponoʻoki lāʻau lapaʻau lapaʻau, me he mea he pilikia o ka mea hōʻemi, a me ka manawa e cardiac make.

Ma keia hookolokolo ana, nā mea maʻi i ano pallor pili me ka ho'ēmi i kā cardiac auaiaea. Kahahānai artery lāʻau ikiʻai wale i māhunehune detectable - he mea pohihihi a me ka nawaliwali. Auscultation malama i mea hoʻonāwaliwali maoli o 2 nanahe a me splitting. ECG mea,ʻaʻole i lawa informative - hoailona o ka hypertrophy e paa wale i loko o loa stenosis. Ka loa ma ka hōʻike echocardiography ma ka mea e Loiloi i ka aortic kiwikā. i hōʻailona nā puapua a meʻia naʻe, hou weheʻana - i ka papa kuhikuhiE PalekanaEND_LINK ana hoʻohālike, i kokua, e huai ae i kēia mahele.

Aortic kiwikā insufficiency

Ka inoa i haawiia i ka pathology wehewehe aku nesmykaniem mau'ēheu. O kŰia hiki aku ai a hiki i ka hoi ana mai o ke koko, kiola ia i loko o ka ventricle hema e ia lŘlŘ i diastole.

Emi pinepine ka mea hiki aku ai i ka syphilis, aortic aneurysm, ka aorta, hypertension, Marfan ka maʻi pale, systemic lupus erythematosus.

Aortic kiwikā Radio nui i kūlana ma ka holo. Kāpili panina o kona mau'ēheu ke kumu regurgitation, 'o ia hoʻi, ke hoʻi o ke koko a hiki i ka hema ventricle ninini. Ke hualoaʻa Ua excessive koko ka leo o kona lua, i hiki aku ai i overload a me ka stretchability. O ka wawahi systolic hana, a kiʻekiʻe ke koko, hiki aku ai i ke kūpono 'ana o ke hypertrophy.

Like stenosis, pathology ua iho i manao ai wale i ka loa degere o ka ole. I ka exertion pokole i, ka mea, ua pili me ka pulmonary hypertension. Pain pilikia wale nō i loko o 20% o ka hihia. I ka Ia manawa hōʻike auscultation a me symptoms o pathology:

1. Pulsation o ka carotid arteries.
2. Symptom Duroziez ole hanana systolic ohumu ma ka femoral artery. Ua lŘlŘ ka wā āna i ae like nō kokoke i ka Papa Hana wahi.
3. Symptom angioedema - hoʻololi i keʻano o nā lehelehe, a kui i kulike ai me ka pulsation o na arterioles.
4. Traube kaulua nanahe, nui, "pūkuniahi" i ala mai ma luna o ka femoral artery.
5. Symptom de Ka Musset, hoikeia mai luliluliʻana i kona poʻo.
6. Diastolic halulu ma hope o 2 nanahe 'ia ma luna o auscultation o ka naʻau, e like me hoʻonāwaliwali i 1 kona nui.

Informative ki ina hana like nā echocardiography a me ka catheterization cavities. Ka mea, ae oe, e Loiloi i ka aortic kiwikā, e like me ka Hoʻokolo i ka buke o regurgitated koko. Ma ke kumu o kēia mau haʻawina hoʻoholo i ke oolea o ka Hope, a kamaʻilio maila i ka hoopuka ana o ka mea e pono ai no kaʻoki kino.

Loa ka nele o ka buke nui o ke regurgitation, mālama nui symptomatic ponoʻoki lāʻau lapaʻau lapaau. Pau e pono ai, e haawi aku -ʻimi hoʻopunipuni aortic kiwikā, a ae oe, e hoʻihoʻi kuleana pili i ka naau. Inā pono, ia symptomatic ka lapaʻauʻia.

Stenosis a aortic kiwikā - ka loa e like me ka naau mā, a e hookuu i ka hope o ka maʻi kūloko paha systemic. Ke pathology progresses, aole lohi, e leie manawa e diagnose ia. Hoikehonua, ano o ka hana, e kōkua hoihoi kiwikā papa a me ka hoʻoikaika 'ana i ka hoʻomanawanui ka kulana.
