Chiremba anopinza waya yekutungamira nepano tsono, anobvisa tsono, uye ndokuitsiva neyekuzivisa, chiridzwa chine madoko maviri ekuisa michina inochinjika. Ipapo yekutanga tambo waya inotsiviwa netambo yakaonda. Chiremba anodarika chubhu refu yakatetepa inonzi catheter yekuongorora pamusoro petambo nyowani, kuburikidza neanosuma, uye mutsinga.Kana yangopinda, chiremba anoitungamira kune aorta uye anobvisa waya yekutungamira.

Ne catheter pakuvhura kwecoronary arteri, chiremba anopinza dhayi uye anotora X-ray.

Kana ikaratidza kuvharika kunorapika, chiremba anotsigira catheter kunze ndokuitsiva nekateti inotungamira, asati abvisa waya.

Iyo yakatetepa waya yakaiswa uye inotungamirwa kuyambuka iyo yekuvhara. Bhatiro catheter inozoendeswa kunzvimbo yekuvhara. Bhaluni rakaputirwa kwemasekonzi mashoma kumanikidza iko kuvhara kumadziro etsinga. Ipapo yakadzikiswa. Chiremba anogona kukwidzira chibharumu dzimwe nguva shomanana, nguva imwe neimwe achiizadza zvishoma kuti awedzere nzira.

Izvi zvinogona kuzodzokororwa pane yega yega yakavharidzirwa kana yakamanikana saiti.

Chiremba anogona zvakare kuisa stent, yakakwenenzverwa simbi scaffold, mukati meiyo coronary artery kuti irambe yakavhurika.

Kana iko kumanikidza kwaitwa, dhayi inorowa uye X-ray inotorwa kuti itarise shanduko mune tsinga.

Ipapo iyo catheter inobviswa uye maitiro acho apera.
