Mudziyo uyu unonyanya kubatsira pakutarisira nzvimbo yekuboorwa mutsinga dzeropa (dziri muruoko), iyo iri kufarirwa zvakanyanya kupfuura kupinda mutsinga dzeropa dzechikadzi nekuda kwenjodzi shoma yematambudziko uye kukurumidza kupora kwemurwere.

Maitiro ekuvharira tsinga iyi anobvumira kushandiswa kwesimba rekumanikidza kwakanyatsogadziriswa, zvichiita kuti ropa ribude zvakanaka ukuwo ropa richiyerera muruoko. Inzira yakachengeteka, inoshanda, uye inobatsira murwere pakurapa mushure mekuvhiyiwa.

Iyo Bhendi reTR rezvekurapamudziyo wekurapa wakagadzirirwa kubatsira kubvisa ropa kubva muropa (maitiro ekumisa kubuda kweropa) mushure memaitiro anosanganisira kupinda muropa kubva muropa, akadai se cardiac catheterization, angiography, kana mamwe maitiro e radiology. Inonyanya kushandiswa mushure memaitiro apo radial artery (iri muruoko) inowanikwa, sezvo nzira iyi iri kuramba ichifarirwa nekuda kwenjodzi yayo shoma yematambudziko kana tichienzanisa nekupinda muropa kubva muropa kubva muropa kubva muropa kusvika muropa kubva muropa.
