Who is the first man in the world to get bipass surgery and when?

He is seriOSly my dad! No Joke. His Name is Frederick Otto Bloechl, and got the surgery in 1971. He is also the first man in the world to survive a bipass the longest, to the ripe old age of 48 (in year 2010) years. He got the surgery when he was eight, and i could still see his scar from the surgery at his age! Pretty cool, huh? He's also in most of the medical books, which i don't read much. He had his surgery at the age of eight.
