I recently watched a movie produced by HBO titled "Something the Lord Made". No, it's not really a religious story. It is about Dr. Alfred Blalock, & his assistant, Vivien Thomas. They developed the procedure in the 1940's that saved the lives of us "blue babies", with Tetrology of Fallot. It is a fascinating story. I highly recommend it! It really blew me away that this story is about the exact procedure that saved my life when I was 2 years old. It's referred to as the Blalock-Taussig procedure. This procedure was truly the beginning of modern heart surgery. Here's the film's website: http://www.hbo.com/films/stlm/
