Replying to @TWilsonMD @DrIHHashmi1 and 9 othersI have many ostial RCA ROTAs, so it is easier to understand when you see it. This case was performed by my colleague Dr SUGIE, who will be the next gen. of ROTA experts. Finally, DES is implanted and IVUS shows a 4mm AG. I hope this is helpful to you. Video is at 3x speed.
