Glad they caught it on time! Good luck with the surgery and recovery.
I've had a couple of CT angiograms to try to get a handle on the status of my arteries. So far so good (partial blockages, but less than what is typical for my age). In another couple of years, I think I'll get another to check out the status. It's hugely important to catch blockages before heart damage is done.
