Enye indlela entsha yokuhlinzwa kwenhliziyo evulekile yamavalvu amaphaphu avuzayo

Ngomhla ka-Dec. 8, 2021, u-Jasmine waba ngesinye seziguli zokuqala e-Florida ukuthola i-Harmony™ Transcatheter Pulmonary Valve. Ivalvu ifakwa nge-catheterization yenhliziyo futhi inikeza enye indlela yokuhlinzwa kwenhliziyo ezigulini ezinamavalvu avuzayo wamaphaphu. Isibhedlela Sezingane sase-St. Joseph siyisikhungo sokuqala eFlorida futhi phakathi kwezibhedlela ezimbalwa ezikhethiwe ezweni ukunikeza lobu buchwepheshe bezinguquko. 

I-Congenital heart defects (CHD) iwuhlobo oluvame kakhulu lwezinkinga zokuzalwa, ezithinta izinsana ezilinganiselwa ku-40,000 e-United States unyaka ngamunye. I-Tetralogy ye-Fallot ingenye yama-CHD avame kakhulu futhi zonke iziguli ezizalwe zinalokhu kuxilongwa zidinga ukuhlinzwa kwenhliziyo kokuqala ngesikhathi sosana futhi ngokuvamile izinqubo zenhliziyo ezengeziwe kamuva ebuntwaneni noma phakathi nokukhula. 

Phakathi nenqubo ka-Jasmine, uDkt. Ringewald wafaka i-Harmony valve elayishwe kwi-catheter yayo yokulethwa emthanjeni osemlenzeni wakhe futhi waqondisa i-catheter nge-fluoroscopy endaweni yevalvu yakhe yamaphaphu evuzayo. I-valve ye-Harmony yasetshenziswa futhi lapho ikhululiwe, i-valve yaqala ukusebenza ngokushesha.

I-Harmony inohlaka lwentambo ye-nickel-titanium emise okwe-hourglass ene-valve yethishu yenhliziyo yengulube ethungelwe ngaphakathi kuyo. Umklamo oyingqayizivele, ozikhulisayo uvumela idivayisi ukuthi isebenzele iziguli ezihlukahlukene.

Inqubo ka-Jasmine yaba yimpumelelo futhi esikhundleni sokuhlala cishe isonto lonke esibhedlela okuvamile kwezinqubo eziningi zokuhlinzwa zenhliziyo evulekile, wadedelwa ngemva kosuku olulodwa nje.

Isibhedlela Sezingane sase-St. Joseph siyikhaya lohlelo oluphelele lwendawo yase-Tampa Bay okuwukuphela kwalo oluphelele lwesifo senhliziyo sokuzalwa, futhi odokotela baso benhliziyo yezingane benza amakhulu ezinqubo unyaka ngamunye ukuze belaphe izimo zenhliziyo ezizalwa nazo nezitholiwe ezinganeni zanoma iyiphi iminyaka, kuhlanganise nezinsana. Ubambiswano phakathi kweSibhedlela Sezingane sase-St. Joseph kanye neSibhedlela Sezingane se-UPMC sase-Pittsburgh kunikeza imindeni yonkana eFlorida ukufinyelela okungakaze kubonwe izinga eliphezulu lokunakekelwa kwenhliziyo kwezingane elitholakalayo. Ngokuhlangene, bahlinzeka ngokunakekelwa okukhethekile kwenhliziyo nemithambo yegazi ezigulini ezisukela ezinganeni ezisesibelethweni kuya kubantu abadala abanesifo senhliziyo abazalwa nabo.
