Now you're starting to understand why cardiac surgeons are paid so highly - supply is low and demand is high. Also you can understand why it took so long in medical history to even be able to do that. When I was a kid, if you had a heart attack, you died, there were no other options - attempting open heart surgery would have been murder (literally).

It is awful hard to suture up an artery, you need lots of very tiny, very accurate stitches. And you can't just goober on some caulking...
