Cardiology. mwoyo mavharuvhu - hwomunhu

Healthy mwoyo unonzi simba, kushanda akaramba uye pasina kuvhiringidzwa muviri. Kukura kwayo unoenderana ukuru yevanhu chibhakera uye hunorema anenge mazana mashanu magiramu. Kuwedzera kwaro chikuru basa kuitira (kugadzikana) ropa aibuda kuipa, zviri anokwanisa kuchinja kuti kuchinja zvinodiwa nhengo dzose.

Ndichishanda somushumiri maviri-nzira pombi, mwoyo anopa ropa kuparadzirwa pakati muviri. Achishandisa tsandanyama rusvingo (septum) rakakamurwa sezvikamu. hafu neimwe unotora makamuri maviri (atria uye ventricles).

Kodzero atrium anogamuchira ropa kubva rose repasi uye okumusoro nhengo dzomuviri. Maererano tricuspid vharuvhu ropa anoenda kurudyi ventricle, izvo, kuburikidza chiedza vharuvhu hunde mairi pumps ropa. Oxygenated, zvinonzi akatumira atrium kuruboshwe. Kubva ipapo ari mitral vharuvhu ropa achipinda ventricle kuruboshwe, unova ndiye kutsemuka vharuvhu anovapavhurira ropa rose muviri. Yokusimbisa muviri okisijeni, zvinonzi kwezvinoshandiswa, zvakare anopinda zvakanaka atrium.

Heart mavharuvhu Munotadzanura muna rimwe divi "masuo" pakati pamakamuri. regai chete vanotsigira kusimudzira ropa mberi, asi kuti asashandiswe neshure kufamba. Healthy mwoyo mavharuvhu vane petals, zvinosanganisira nhete, anonzwisisa chimiro zvakajairika tishu. Kana mwoyo akadekara uye reductions kuvhura nokuvhara kuchiitika zvakanaka.

Pakupona zvinogona kukonzera zvokurwara. Heart mavharuvhu inogona akafukidzwa mavanga kana kukuvaradzwa somugumisiro nezvirwere, rheumatic fivha, nhaka zvirwere, mwoyo kurwiswa. Damage anogona kukonzerwa musimba yevanhu zera. Avo vakawanda pangozi ndivo ari mitral vharuvhu. Kana izvi zvaitika reguritatsiya (mitral regurgitation), umo leakage ropa kubva vharuvhu iri neizvi mirayiridzo pashure nokuvhara mavharuvhu. Panyaya iyi, iro basa mwoyo kwava zvikuru - iri kuedza kushandisa zvakakodzera uwandu ropa mumuviri uye aripire kukundikana. Kuvadza mwoyo mavharuvhu uye anosanganisira stenosis (kuderedza pamusoro vharuvhu hwomukova), umo ropa ichipfuura vharuvhu zvakaipa. Panyaya iyi, sezvo muviri unotanga kushanda nesimba kuti ropa zvakakwana kuburikidza rakamanikana buri. Kwakadaro mamwe makakatanwa mwoyo simba payo, chinoita kuti kuwedzera uye anoita zvirwere zvakasiyana-siyana.

Muzviitiko zvakawanda, vanhu pakutora zvinokosha mishonga uye pasi zvakakodzera zvokurapa kutarisirwa, mwoyo chirwere, hupenyu huzere. Zvisinei, zvinoitika kuti mishonga urege kuuyisa zvainoita kana dzinokanganisa utano. Zvichitsamira pamamiriro ezvinhu, chiremba anogona mishonga kudzorerwa kana prosthetic mitral vharafu. Zvisinei, kana zvikuru deformations kana kukuvara kupora haazogumisi zvandinenge zvabuda. Zvakadaro kwakandiomera ezvinhu, unofanira mwoyo vharafu kutsiviwa. Kuvhiya kupindira chinodiwa panguva kutanga chirwere chemwoyo uye chinokosha kuderera ejection ropa kuruboshwe ventricle (systolic dysfunction).

The rokuvakazve (Kudzorerwa, mapurasitiki) pakati vharuvhu rinoitwa nokuchengetedzwa kwomwoyo wake vharafu pachake. Panyaya iyi, avhiyiwa murwere haasi vanoda kugara kugamuchira ropa rive dete mishonga.

With simba, kwete amenable kugadzirisa ukama gadzai yokutsiva (prosthetic) vharafu. Nokuti chinangwa ichi, zvemaziso (chakagadzirwa) kana chaivo (zvinyama) prostheses.

Zvokuimba mwoyo mavharuvhu yakavimbika zvikuru uye rakasimba, regai zvinoda kutsiviwa. Zvisinei, vane kuchikosha drawback - kuitira kudzivirira coagulation ropa, murwere mushure kuvhiyiwa ratidzai tsamba medicaments muupenyu.

Biological prostheses yaigadzirwa mishonga zvakaipa mhuka mwoyo chakapatsanurwa (mabhiza, mombe kana nguruve). Pashure kugadzwa zvinyama vharuvhu prosthesis murwere haungopiwi mishonga, ropa thinners. Zvisinei, upenyu pabasa prosthesis pane zvaasingakwanisi nguva, uye pashure imwe nguva (gumi kusvika namashanu) raparadzwa, zvichiguma zvichibvira rechipiri kutoshanda.
