My grandfather was the second person DeBakey installed an aortic graft on. DeBakey sewed the graft on his sewing machine at home then had it sterilized. He flew my grandparents to Dallas from El Paso to do the surgery. My grandfather lived another ten years. Dr DeBakey corresponded with my grandmother over the years checking on Mac (my grandfather.) Amazing surgeon, but seemed genuine also. If you work in medicine you know that’s uncommon.
