Ukuphindaphinda kwe-tricuspid kungenye yezifo zenhliziyo lapho umsebenzi we-valve we-tricuspid uphazamiseka, okwenza kube nokugeleza okuphambene kwegazi kusuka ku-ventricle kwesokudla kuya kwe-atrium.
Izimbangela zokuphindaphindiwe
Ngokuvamile, lesi sifo senzeke ngokukhuliswa kwe-ventricle efanele, ephindaphindiwe, edala ukuhluleka kwe-valve. Kanti futhi ukuphindaphinda kwegazi kungabangela ukucindezeleka kwe-pulmonary, ukwehluleka kwenhliziyo , ukuphazamiseka kwemithambo ye-pulmonary. Ngokuvamile, kubonakala kungemuva kokulimala kwezicubu ze-rheumatic, i-carcinoid syndrome, i-endocarditis ye-septic. Ngaphezu kwalokho, lesi sifo singakhula ngokusetshenziswa kwemithi ethile isikhathi eside (i-Ergotamine, i-Fenfluramina, i-Phentermine).
Ukuphindaphinda isikhathi eside kakhulu kungabangela ukuphefumula kwe-atrial nokuhluleka kwenhliziyo.
Amadijithi we-tricuspid regurgitation
Kuzokwelapha, kunezigaba ezine zalesi sifo:
- Ukuziphindaphinda kwezinga elingu-1. Ukujova kabusha kwegazi akubonakali nakancane. Awekho ukubonakaliswa kwemitholampilo yesifo.
- Ukuziphindaphinda kwezinga elingu-2. Ukulahlwa kwegazi kunqunywe ngaphakathi kwamamitha amabili ukusuka ezindongeni ze-valve. Izimpawu zomtholampilo azikho noma zithobe kakhulu. Kungase kube nokunciphisa kancane kwemifino yomlomo wesibeletho.
- Ukuziphindaphinda kwezinga lesithathu. Kukhona ukudonsa egazini okungaphezu kwama-2 amentimitha ukusuka ku-valve ye-tricuspid. Ngaphezu kokutshala kwemifino, ukuphelelwa umoya , ubuthakathaka, ukungalungi kwisigqi sokushaya kwenhliziyo kungabonwa.
- Ukuziphindaphinda kwe-4th degree. Ukuxoshwa kwegazi okunamandla ku-atrium. Isithombe esitholakala emtholampilo: ukuvuvukala nokunciphisa izinga lokushisa kwamagatsha angaphansi, ukuvuthwa okuzwakalayo esifubeni, ukuphazamiseka kwenhliziyo enamandla, ukwanda kwesibindi, nezinye izimpawu zokuhluleka kwenhliziyo.
Ukwelashwa kwe-tricuspid regurgitation
Ukuphindaphindiwe kwezinga eliphansi lochwepheshe odokotela kubhekwa njengendlela ehlukile yokujwayelekile, engadingi ukwelashwa okuqondile. Uma kunesifo esithile, khona-ke nguye ophathwayo.
Ngezinga lesibili lesi sifo, ukwelashwa kunomkhawulo nakwezinyathelo ezijwayelekile kanye nokuvimbela, kanti ngezinye izikhathi - ngokuthatha imithi ethuthukisa ukusebenza nokuphumula umsizi obushelelekile wezinsizwa zenhliziyo.
Izinga lesithathu nelesine lihlanganisa izindlela ezizongayo zokuhlinzeka. Ngaphandle kokwelapha izidakamizwa, i-plastic valve flaps noma i-prosthetics ingaboniswa.
