that this procedure will get the answers you need with the best outcome. That reassurance is based on this procedure having been done so many times by your team so that the experience makes it almost "routine." At the same time they are letting you know that they are likewise experienced in dealing with a more emergent finding that involves major arterial blockages. Fully informing without unduly frightening worst case and the rarest outcomes for those undergoing these procedures is incredibly important and it sounds like your team has a good approach to doing so.
Your DU family has you firmly in our thoughts and best wishes. I have confidence that you will be back with us better than ever--and quite soon! May your positivity sustain you and push any fears well to the side.
Best wishes!
