Kutanga, anesthesia yemuno inorwadza nzvimbo yekugomera. Ipapo chiremba anoisa tsono mutsinga yevakadzi, tsinga inoyerera ichidzika negumbo. Chiremba anoisa waya yekufambisa kuburikidza netsono uye obva abvisa tsono. Iye anochitsiva nekwaizivisa, chiridzwa chinobhururuka chine madoko maviri anoshandiswa kuisa michina inochinjika senge catheter mumudziyo weropa. Kamwe iyo yekuzivisa painenge yavapo, iyo yekutanga girairewire inotsiviwa neakajeka waya. Iyi tambo nyowani inoshandiswa kuisa catheter yekuongorora, chubhu refu inoshanduka, mutsinga uye kuitungamira kumoyo. Chiremba anobva abvisa waya yepiri.

Nekateti pakuvhura kweimwe yetsinga dzekoniyoni, chiremba anopinza dhayi uye anotora X-ray. Kana ikaratidza kuvharika kunorapika, chiremba anoshandisa imwe waya yekutungamira kuti abvise catheter yekutanga oitsiva nekateti inotungamira. Ipapo tambo yaishandiswa kuita izvi inobviswa yoiswa neimwe yakanaka tambo iri kumberi mhiri kwekuvhara.

Imwe catheter yakagadzirirwa kucheka kwechironda yakafambiswa pamberi penzvimbo yekuvhara. Bhaluni rakamanikidza-pasi rakanamatira padivi pemucheki, rakafemerwa, rinoburitsa maronda echinhu kumucheki.

Iyo yekutyaira unit yakavhurwa, ichikonzera iyo yekucheka kutenderera. Chiremba anofambisa lever pane yeyuniti yedhiraivhu iyo inofambira mberi mucheki. Zvidimbu zvekuvharika zvainocheka zvinochengeterwa muchikamu checatheter chinonzi mhino kusvikira dzabviswa panopera maitiro.

Kutenderera iyo catheter uchikurisa uye kushomeka chibharumu kunoita kuti zvikwanise kucheka kuvharika munzira ipi neipi, zvichitungamira kuyunifomu yekudzikisira. Stent inogona zvakare kuiswa. Ichi chi scaffold chesimbi chakateyiwa chakaiswa mukati meiyo coronary arteri kuitira kuti ngarava ivhurike.

Mushure mekuita, chiremba anopinza dhayi uye anotora X-ray kutarisa shanduko mutsinga. Ipapo iyo catheter inobviswa uye maitiro acho apera.
