Mehato e khethehileng ea ho buoa sebaka sa valve ea aortic:
1. Ho seha le ho theha potoloho ea extracorporeal
2. Ho chesoa ha aortic .Kamora ts'ebetso ea cardiopulmonary bypass , ha mocheso o theohetse ho 30 ℃, aorta e nyolohang e ne e koetsoe, 'me ho tšeloa cardioplegia e batang, ha pholile ea pelo e ntse e etsoa.Ka mor'a ho tšoaroa ha pelo, ho ile ha etsoa ho phunyeha ha aorta e pota-potileng kapa e oblique, 'me karolo e ka tlaase ea sekhahla e ne e le hoo e ka bang 1-1.5cm ho tloha ho buleha ha methapo e nepahetseng ea mali. ho nkela sebaka sa lefu la aortic valve
3. Mohala oa ho hula o sutured ho e 'ngoe le e 'ngoe ea litsela tse tharo tsa valve ea aortic.
4. Ho tlosoa ha valve Li-lobe tse tharo li ile tsa tlosoa ka thoko, tsa siea 2mm moeling.Ka mor'a moo lesela le calcified lesale le tlosoa.Lesale le ne le lekanngoa ka meter ea valve ho fumana palo ea valve ea maiketsetso
5.Suture Khoele e ncha ea polyester ea 2-0 e ne e sebelisoa bakeng sa suture ea materase ea nakoana ho tloha holimo ho ea tlase.Ka mor'a hore lesale le rokoe, mela ea suture e lokela ho aroloa ka ho lekana le ho aroloa pakeng tsa lesale le valve ea pelo ea maiketsetso.Sebaka sa nale ka kakaretso se ne se le 2mm
