Hi,
I am so sorry for your ordeal. My husband does Interventional Radiology, he puts in stents. Can I let him read your post ? He may have some suggestions.

I know just from listening to him two things. What you went through is not the standard and if you need to have another artery taken care of it is important to do that. But I can understand after what you went through you want to stay far away from any hospital.
