Ukusetyenziswa kwe "BiVACOR iyonke yeNtliziyo eyenziweyo", isixhobo sesinyithi se-titanium senze ukuba eyona bhulorho iphumeleleyo yokufakelwa kwentliziyo ehlala ngaphezulu kweenyanga ezintathu. Isigulane sakhutshwa esibhedlele nentliziyo eyenziweyo isafakelwa. Ufumene uqhaqho-fakelo lwentliziyo yomxhasi kwiintsuku ezili-100 emva kokufakelwa isixhobo sokwenziwa kwaye ngoku uchacha kakuhle. Ngaloo ndlela umguli wasinda kangangeentsuku ezili-100 ekwisixhobo sentsimbi esathabathel’ indawo intliziyo yakhe. Isixhobo sisekelwe kwipompo ye-rotary centrifugal, isebenzisa i-impeller ene-magnetic levitated, inendawo enye ehambayo, ingenayo i-valve, kwaye ayinayo inkqubo yokumisa i-no-contact. Yaphuhliswa njengebhulorho yokufakelwa kwentliziyo kodwa inamandla okusebenza njengotshintsho olusisigxina lwentliziyo yomntu. Ukuba kunjalo, iya kuba yintlupheko kwizigulana ezingakulungelanga uqhaqho-fakelo lwentliziyo kunye nabaninzi kumgca omde wezigulana zokusilela kwentliziyo ezilindele uqhaqho lofakelo lwentliziyo.
Isigulana sokungaphumeleli kwentliziyo silindele ukutshintshwa kwentliziyo safakelwa "iNtliziyo ye-BiVACOR iyonke ye-Artificial" njengebhulorho ngaphambi kokuba intliziyo yomnikeli ifumaneke. Le nkqubo yokufakelwa kwesixhobo yenziwe ngempumelelo liqela leklinikhi yeSibhedlele saseSt Vincents eSydney ngasekupheleni kwe2024. Ekuqaleni kwe-2025, isigulane sakhutshwa esibhedlele samenza umntu wokuqala emhlabeni ukuba ashiye esibhedlele kunye ne "BiVACOR Total Artificial Heart". Emva kweentsuku ezingaphezu kwe-100, elona xesha lide kakhulu kwisigulane esinolu kufakelwa, wafumana ngempumelelo ukufakelwa kwentliziyo yomxhasi ekuqaleni kuka-Matshi 2025. Isigulane ngoku silulama kakuhle.
| Ekupheleni kuka-2024: "I-BiVACOR iyonke yeNtliziyo ye-Artificial (TAH)", isixhobo sensimbi ye-titanium efakwe ngempumelelo kwisigulane esiyindoda kwiminyaka engama-40 ejongene nokuphelelwa ngamandla kwentliziyo, elindele ukutshintshwa kwentliziyo yomxhasi. |
| Ekuqaleni kukaFebruwari 2025: Isigulane sakhutshwa esibhedlele simenza umntu wokuqala emhlabeni ukuba ashiye esibhedlele kunye nokufakelwa kwe-BiVACOR TAH. |
| Ekuqaleni kukaMatshi 2025: Isigulana sasinda kwisixhobo se-titanium ngaphambi kokuba sifumane uqhaqho lofakelo lwentliziyo ekuqaleni kukaMatshi ka-2025 kwaye ngoku siyachacha. |
Isigulana esonakele kakhulu sentliziyo sasinda kweso sixhobo sentsimbi esimiliselweyo kangangeentsuku ezili-100 esenza umsebenzi wentliziyo yaso ngexesha lokuvala ibhulorho ngaphambi kokuba kutshintshelwe intliziyo yomxhasi.
I-BiVACOR Iyonke yeNtliziyo eyenziweyo yimpompo yegazi ene-rotary biventricular efakelweyo. Isebenzisa i-impeller enemagnethi ekuphela kwayo ehambayo. Ukutshintsha isantya se-impeller kuvelisa "ukubetha". Isixhobo asikho i-pulsatile kwaye asinazo iivalvu kwaye sinenkqubo yokumiswa yokungabikho koqhagamshelwano. Ifuna kuphela ipakethi yebhetri ukuze isebenze.
Inkqubo ye-BiVACOR TAH ithatha indawo yomsebenzi wentliziyo enesifo kwizigulane zentliziyo. Yenzelwe ukuvala ixesha lokufakelwa kwentliziyo. Kwimpumelelo yamva nje, esi sixhobo sibonise ixesha lokuvala elingaphezulu kweenyanga ezintathu nto leyo ebonisa ukuba sinokuba namandla okuthatha indawo esisigxina yentliziyo yomntu. Ukuba kunjalo, iya kuba yintlupheko kwizigulana ezingakulungelanga uqhaqho-fakelo lwentliziyo kunye nabaninzi kumgca omde wezigulana zokusilela kwentliziyo ezilindele uqhaqho lofakelo lwentliziyo.
Ukungaphumeleli kwentliziyo (ekwabizwa ngokuba yi-Congestive heart failure okanye i-Congestive cardiac failure) yimeko apho intliziyo isilela ukumpompa igazi elaneleyo njengoko kufuneka. Yimeko enzima efuna ukungenelela kwaye inokubangelwa ngenxa yezizathu ezininzi ezibandakanya isifo senhliziyo, ukudumba kwentliziyo, uxinzelelo lwegazi oluphezulu, i-cardiomyopathy, njl. Abantu abangaphezu kwezigidi ezingama-60 bachatshazelwa yile meko kwihlabathi jikelele. Uninzi lufuna uqhaqho-fakelo lwentliziyo nangona kunjalo kukho umgca omde wokulinda ngenxa yokufumaneka kwentliziyo yomxhasi. Isixhobo esifakelwayo esisebenzayo njengokutshintsha okusisigxina kwentliziyo yomntu sisidingo esikhulu seyure kwizigulana zokusilela kwentliziyo.
