Worst part of stints is having to lay absolutely STILL for 30 min after they take the catheter out of your femoral artery. But do it, you don't want a bleed. Ask me how I know. If you end up having a bypass (a future problem if ever for you) demand that they do not use the heart/lung machine, find a surgeon who will operate while your heart is beating. (New vs. old tech.) My two cents.
SO glad you got a milder warning for your heart conditions. Your life will change for the better now.
We should go through this shit at 18 instead of 45 so we would appreciate our health while it's at it's peak. Smart ass 18-year-olds.
