In this 2nd part of a 2-part series on the world-famous cardiac surgeons Drs. DeBakey and Cooley, we cover their life's work, their feud, and eventual reconciliation. In addition, the history of artificial hearts is covered, as well as other topics, including the reason for Jehovah's Witnesses refusing blood transfusions. And in the latest Suture Tales, the Vineberg procedure is brought out of the dustbin of history, given a shake, and covered in detail!
