Tricuspid vharafu: tsananguro, mamiriro, mashandiro uye vawana kuremara

Muvanhu, tricuspid vharuvhu runodikanwa zvisaora, kuitira kudzivisa ropa neshure kufamba. Akaisa pamusoro Kuparadzana mutsetse rwerudyi atrium uye runoenzanirana ventricle. vharuvhu mamiriro iri rinoumbwa unobatanidza kwamahwendefa. Kukanganisa basa rake ngozi upenyu hwevanhu.

mamiriro

Tricuspid vharafu, maererano mabhuku nesayenzi, anonziwo tricuspid. Kana inofamba kwemoyo, pezvakaitwa zvose zvaitika panguva imwe chete. Kana blockage kunoitika madhipatimendi kusakosha nguva, kamwe muviri anonzwa yekudyidzana kuchinja mamiriro. Mamiriro utano iri kuipa kamwe, zvinovawo zvakaoma kufema uye hazviiti kutama.

Tricuspid vharafu riri kuruboshwe pamusoro sternum. Ndizvo chikamu kupomba hurongwa kupomba ropa. Zvinokosha chivharo rudzi anovhura pasi kumanikidzwa vabudiswa ropa. Kuvharwa imhaka reflux pamusoro Urume mauto rwoga nokuda kwokudzvinyirira pamusoro pechiso mashizha.

Rushoma kuvhara of tricuspid vharuvhu kunoitika nokuda kuzvivaraidza mwoyo tsandanyama kana vasingachakwanisi ishande zvakanaka. Nokuda kuti kutyorwa kuri redistribution yomunyika Matambudziko vanotanga kuputsa zvinyama, zvichiguma nokuumbwa chemwoyo kukatyisidzira. Zvimwe zvirwere muri vaikurudzira zvokurwara kwakadaro.

basa muviri

Tricuspid vharafu chikamu kweropa dzevanhu hurongwa. A huru uwandu ropa richibva mwoyo kupinda yeropa zvakawanikwa, achipfuura ose arteries uye capillaries, izvozvo anokurukura masero pamwe okisijeni uye anogamuchira carbon dioxide. With saturation ichi kunoitika kuora zvigadzirwa kubva kupatsanurwa chicherwa uye micronutrient anova nerima. ropa iyi inonzi venous.

Next pane redistribution zvakarurama munharaunda mwoyo, zvimwe kufamba rinowanikwa mune arteries dzose mapapu kuti okisijeni vapfume. Tricuspid vharafu ane zvinopfuura chimwe zvinoita neizvi ano ichivharira. Zvakafanira kuti kuparadzana kushanda pamwe: kuruboshwe, ventricles kurudyi uye atria.

Ropa anozadza akasiya munharaunda mwoyo, ipapo kubva atrium inoyerera kupinda ventricle. Pashure paizvozvo pane makopi wokufambisa. Anodzoka deoxygenated ropa zvakarurama atrium, ipapo kupinda zvakanaka ventricle, uye anoenda kunze pulmonary riparadzirwe. Mushure oxygenation guru denderedzwa kutenderera inodzokororwa zvakare Via atrium kuruboshwe uye ventricle.

vharafu mabasa

Sezvo kuruboshwe uye zasi mwoyo vari nemasiraidhi akapendwa, nguva inodiwa kuti adzikatidza neizvi pakati madhipatimendi kuitika. Mushure ropa kupomba kutenderera kunoitika: pane yakatarwa mvura iri ventricle, zvichiteverwa simba ejection ropa mukati yeropa. The vharafu Hurongwa inopa yakarurama oparesheni:

• Zvinowanikwa munzvimbo mwoyo kuruboshwe anonzi mitral.
• Triskupidalny.
• The vharafu ari pulmonary tsinga.
• Kutsemuka sezvo fiyuzi pakukura hurongwa.

Vanachiremba vanoshandisa kutsunga regurgitation, zvichiratidza kutanga ropa riyerere ari neizvi mirayiridzo achishandisa vharuvhu. Kuti izvi zvisaitike, dzakanyorwa blockers vane nguva kuzadzisa mitemo zvinotevera:

• Mitral vharafu yakazarukira chete panguva kupomba ropa kubva atrium rworuboshwe kupinda runoenzanirana ventricle. Rwunopera kana akasunungura akaunganidza zvinwiwa kupinda yeropa. The vharafu mamiriro parizvino ichibhabhamisa maviri.
• Tricuspid kutsemuka vharafu anovhara ndima pakati rworudyi atrium uye runoenzanirana ventricle. Jobs rakafanana mitral. The mamiriro ane mapepa matatu.
• Pulmonary chokuita munzvimbo pakati pulmonary hunde uye yakarurama ventricle. Inoshanda kuderedza kuitika bindepinde panguva yokuzorora mwoyo tsandanyama.
• Kutsemuka riri nzira yokubudisa nzira ventricle kuruboshwe. Anovhara backflow ropa kubva yeropa panguva dzokuzorora mwoyo tsandanyama. Inoitwa vatatu semilunar cusps.

Kukura mwoyo chirwere

Tricuspid vharafu zvichiita kuti paumbwe ropa regurgitation kana kuzvishandura ayo aibuda nzira kubva atrium kusvika ventricle. Izvi zvinoitika panguva systole (kurudyi ventricle zvibereko). Makasununguka nebhanhire sag pasi kwokudzvinyirira kwomunhu ropa.

mamiriro kwakadaro kunogona inoumbwa zvokuimba blockage yacho yeropa. Varwere kazhinji vawane chirwere panguva yohupenyu hwavo. Asi pane mienzaniso kubva vachiberekwa mwoyo kuremara.

pathologies

Kutyora vharuvhu nokuda kwezvikonzero zvinotevera:

• Kushaya micronutrients pamuviri, pamusoro izvo arambe achirema uye elasticity kuti munyama, kusikwa vharuvhu ndiro.
• dzichipfekeka Kuvhiringidza of tricuspid vharuvhu zvingaitika nokuda kukundikana pedyo zvikamu mwoyo.

Nokuda kurega kunotanga ropa mumuviri zvisakakwana kuvhara zviri tricuspid mwoyo vharuvhu. It kungaita munhu kupinda ezvinhu incapacity. Hypertrophic atrial rusvingo inoumbwa ne dilation (kukura) rwerudyi ventricle. Nokudaro akaumba mira pezvakaitwa ari arteries uye mutsinga.

Zvokurwara anogona kuonekwa nevanhu munyika nezvekufadza uye kuzvimba mutsinga dziri mumutsipa nenguva ejection ropa kubva mumwoyo. Venous kumanikidzwa Kazhinji ichiwedzerwa. The chiropa ichiwedzerwa kwazvo.

Zvinokonzera uye zviratidzo

Pakati akasimbisa zvinokonzera ari kunetesa ari tricuspid vharuvhu ndedzinotevera:

• Carcinoid syndrome.
• Migumisiro kukura rheumatic nefivhiri.
• Endocarditis nezvirwere mavambo.
• Zvokuimba kukuvara kana atsamwira kuti papillary tsandanyama Chord.
• Mugumisiro kuitwa myocarditis.
• After cardiomyopathy.
• Mhedzisiro inorema States of thyrotoxicosis.

Vachiberekwa ezvinhu zvinowanzoitika pamwe nemamwe abnormalities marongerwo mwoyo. Tricuspid vharafu stenosis kungaita kuti yokururamisa pechipfuva, chiremba anoona kupfurikidza palpation. chinokosha ruzha panguva systole (ejection ropa kubva ventricle) vo apo kuteerera heartbeats.

Zvisinei, ruzha zvinogona kuonekwa chete kana kuti rikwanise kukundikana. Kazhinji zvishoma kwazvo zviratidzo vakasara vasina akavatarisa. Nokuti yakarurama chirwere kunodiwa paku kudzidza pamusoro namano.

nzira nechirwere

Kana chirwere kunokosha systolic kutsutsumwa panguva inhalation. Izvi unoratidza tricuspid vharuvhu. Zvisinei, cherechedza kuti chiitiko ichi hachisi kugara uye anogona kuva nguva kunyangarika zvachose. Kuzosimbisa rokutanga zvokuongorora inoitwa kwemwoyo unonzi, electrocardiograph.

On kunoguma girafu pamwe zvokurwara akati:

• kurudyi yemagetsi akabatana kutsauka;
• kuwedzera kukura zino P (ari mubhokisi rechipiri uye rechitatu anotungamirira).

Uyewo, maekisirei zvinogona kushandiswa. Nomufananidzo ventricular dilatation kana atrium. Zvarakasiya zvinoonekwa pamusoro echocardiography mifananidzo, wakaiswa zvemamiriro huchiitwa mwoyo masvingo. Mune kuongorora murwere ezvinhu, funga zvinotevera:

• Namarudzi ruzha, uye kukura kwebasa kuonekwa.
• The kukura mwoyo, chinowanzoonekwa ichiwedzerwa.
• Kuvapo kurega kunotanga riparadzirwe madenderedzwa.
• The kwakakura venous kumanikidzwa.
• Kukura chiropa.
• Status pechipfuva.
• Right atrial kumanikidzwa.

chirwere chaiko

Aienda pamusoro vharuvhu hwomukova inonzi stenosis. Izvi zvinoitika pasi pokudzora rheumatic nefivhiri, vachiberekwa malformations, uyewo refu zvemaziso migumisiro. Somugumisiro, chirwere chacho kuwedzera kumanikidza pamwoyo pamadziro. Anowedzera atrium. Tangai kurega kunotanga ari kweropa ino.

Nokuti pakurapa nyoro zviitiko chirwere aite chokudzivirira zviito. Sezvo chechipiri kwokuomerwa kare inokurudzirwa kuvhiyiwa. The vharafu ikarapwa ane scalpel, zvinowanzoguma kunodiwa kuti Musono ndiro kana kusiya pane vatatu chete vaviri. Maererano nenhamba, vanenge 14% wevarwere regai kurarama avhiyiwa.

Asi kunyange pashure vakabudirira kurapwa, murwere ratova kuwana akaremara. It kunodiwa kudzivisa mumuviri nesimba uye narwo nguva nenguva kuongorora kuitira kudzivisa kumwe kufambira mberi chirwere.
